Do the same on successive days for as many coats as you think are necessary. I realize this comment was two years ago and you may well have already known the differencebut before anyone else tries it, it's important to note that common hardware store boiled linseed oil uses an assortment of really nasty drying agents that are countersink drill bit lowes 50 opposite of non-toxic. You'll also want to either drill a row of screws around the outside edge, in the bit you're going to countersink drill bit lowes 50 off, or you'll need clamps all around the edge. The advantage of hollow core doors is that they're flat, stiff, and cheap. I bought 24 feet of 1X3 instead of 12 feet of 2X3 because I couldn't find 2X3 stock and I don't have a table saw to rip 2X4 down to size. Now that we have our material for the vise jaws prepared, cut it to length plus a margin for error.

This means that when you cut with the router from left to right, the bit will tend to pull the router away from you, and when you route from right to left, the router will pull towards you. So, if you're hooking the edge guide along the near side of the board, route from left to right, and when you're hooking it along the far side of the board, route from right to left. Second, always test the position of your bit on scrap material.

Your odds of getting it exactly right by eye are nil. I ended up making a number of practice cuts. The first revealed that I hadn't tightened the screws on the edge guide enough.

The second revealed that the design of the edge guide provided very little support at the end of a board, because of the cut-out for the router bit. In the "Getting Started in Woodworking" video, they had screwed a piece of hardwood to the edge-guide, to provide a continuous -- and longer -- bearing surface.

I may do that myself, some day, but I didn't have the materials at hand, so I clamped some 2x4 scrap to the end of each board, to provide a continuous bearing surface past the ends. The two grooves in the long stretchers and the side groove in the short stretchers have identical layout.

I made practice cuts in scrap until I had the edge guide set correctly, then I cut them all with that one setting. The bottom groove of the short stretchers uses a different setup, so it was back to the scrap, before cutting them.

As I was handling the 2x4's, during the routing, I realized that I really wouldn't be happy with the look of the bench, if it were made from these unfinished boards. They had stamps, pencil marks, and more importantly, incipient splinters left by the saw, none of which I wanted. And I was remembering what other shop furniture made from unfinished pine had looked like, after a few years in the grime of a shop.

So I determined to clean up the boards, to remove the stamps and splinters, and to prep for a finish of some type. There's only the one picture for this step, but it was by far the most time-consuming. I used the hand screws again, to hold the pieces. I used a belt sander to remove the surface problems, then used a small random-orbital sander to remove scratches left by the belt sander.

In total, it required five passes - 50 and 80 grit on the belt sander, , , and grit on the orbital. My advice? Don't do this. If you have jointer and a planer, use them. If you don't, seriously consider using dimensional lumber that has already been planed and sanded. If you are going to try to clean up construction lumber by hand, using a hand plane is a lot faster and more pleasant than using a belt sander.

Except, of course, that to do a good job of planing a board you need a solid bench to hold the board, and you don't have a bench, yet.

Me, I'm stubborn, and nearly always insist on doing things the hard way. Now that we have parts, we'll take some of them -- two legs and two short stretchers -- and make our first trestle. Matching up the parts Not every part and not every cut will be perfect.

Match up your parts so that the less-than-perfect parts are in less-than-critical locations. The top is supported by the top ends of the legs and the top sides of the top stretchers. Stand your legs on end on a flat surface like my door and see if they wobble. If you have an end that isn't quite stable, use it as a foot, where the leveler will make it's flaws unimportant. Check the top edge of each stretcher for straightness.

If one has a bit of a bow, use it for a lower stretcher. It's less critical that the shelf be well supported along its length. Do a trial layout to see how the parts fit together. Label each part to indicate which part joins with which.

Mark the holes The holes we want to mark are the holes through which the threaded rod connecting the two legs will run. The hole for the upper stretcher has to be positioned so that when the rod is running through this groove, the top of the short stretcher is even with the top of the legs. The most precise way I've found for marking the position of this hole is to use a dowel center. Fit the dowel center into the bottom groove, line up the stretcher, and bang on the end with a rubber mallet.

The dowel center will leave a mark indicating the center of the hole. The precise position of the lower stretcher is less critical. I marked out a position 8" from the end of the legs.

Drill the holes In the "Getting Started with Woodworking" video, the holes through the 4x4's were drilled from the back. That is, they start on the side opposite the precisely-positioned mark, and drill through to hit it. I drilled from the mark. That way I could ensure that the hole was where it was supposed to be, on the side where the position was critical.

Brad-point bits are far more precise than twist bits -- they're more likely to start where you want them to, and they're more likely to stay straight. So I started each hole with the brad-point bit, then finished it off with the twist bit.

I clamped a piece of ply on the back, to reduce tear-out. When the holes were complete, I flipped the legs and drilled the countersinks with a 1" Forstner bit. Trying to drill a countersink when the center was already drilled would be impossible with a spade bit or an auger, but Forstner bits are guided by their edges, not their center, so they can handle this job. On thing about Forstners, though -- they have a tendency to skitter around a bit when starting, before they bite.

An easy fix for this is to drill a hole through a piece of ply, and to clamp that to your work, creating a jig that will prevent the bit from drilling in the wrong spot. The countersinks should be deep enough to hold a nut and washer, plus a little bit.

These stretchers already have a groove running their length, centered on the bottom edge. Precise placement isn't necessary, but keeping track of which part is which is. We need a hole in each end of each stretcher. Take care to keep these holes square, you don't want them running at angles. Mark the leg dowel holes Lay a leg flat on your work surface, with the countersink side of the thru-holes down.

Stick a piece of threaded rod in each hole. Take a stretcher that is marked to have one end adjoin the top of this leg, stick a dowel center in its dowel hole, line it up against the leg, using the threaded rod for positioning, You want the top of the stretcher to be even with the top of the leg, or just slightly above it.

Give the end of the stretcher a whack with your rubber mallet. This will leave a mark indicating where the matching dowel hole in the leg needs to be drilled. Repeat with the lower stretcher than adjoins this leg.

Then repeat for the other leg that will form this trestle, and the other ends of the two stretchers. Drill the leg dowel holes When you have both legs for this stretcher marked, drill the other dowel holes at the marks. Again, take care to make the holes square. A board jack is mechanism to provide support to long boards that are being held in the vise. These can be quite sophisticated, involving parts that can be moved both horizontally and vertically.

The simplest mechanism is simply to stick a dowel into a hole drilled into the front of your bench. The "Getting Started in Woodworking" video showed only one hole, drilled in the right front leg, level with the vise. This is useful only for a narrow range of boards. I decided to drill holes at four different heights in each of the front legs, six inches apart.

The Jig Drilling a precisely positioned, deep, wide hole isn't easy, without a drill press. So I bought a WolfCraft drill guide. After experimenting with it, and drilling some test holes, I build a jig around it. To mark the centerline, set a compass to span something more than half the width of the leg. Draw an arc from corner of the leg. The point where the arcs intersect will be on the centerline. With a centerline point on each end of the leg, place a scribe on the point, slide a straightedge up to touch the scribe.

Do the same on the other end. When you have the straightedge positioned so that you can touch both points with the scribe, Countersink Drill Bit Lowes 90 and in each case it is touching the straightedge - without moving the straightedge - scribe the line. Use scribes, rather than pencils or pens, because they make more precise marks. Then mark the second hole on the centerline, six inches below the first. Repeat for the other two holes. To precisely set the span of the compass, use a rule with etched markings, and set the points of the compass into the etched grooves.

Place a centerpunch on each of your four points in turn, and press down to make an indentation. This will mark the center of the hole. Drilling the holes Because of the depth of the holes, drilling each hole became a four step process: 1. Flip the leg, position the jig, and finish the hole off with the Forstner bit. This gives a clean exit. The top hole on each does not extend through, and only steps 1 and 2 are necessary.

If you bought 6' lengths, cut off two 24" long lengths. On one end of each, place a washer and a nut. Screw on the nut only half way, you don't want the end of the rod protruding.

Thread the rods through one of the legs, then set the leg flat on the table. Insert dowels into the dowel holes. Place the matching stretchers into place. Put dowels into the dowel holes at the top end of the stretchers. Place the other leg onto the threaded rod and settle it down onto the dowels. You'll probably have another opportunity to whack away with your rubber mallet.

When you have the other leg seated, the threaded rods will extend father than you want them to. You'll want to mark them so they can be cut to length.

Place a washer and a nut on each threaded rod, and then tighten down the nut to pull everything tight. Depending upon the wrench you are using, and how much longer the rod is than it needs to be, you may find it necessary to stack up a number of washers, so that the nut is positioned where the wrench can operate on it. Once you have pulled everything tight.

You want to cut it slightly below flush. Then take everything apart. Cutting the rods There's nothing very tricky about cutting the rods. Clamp them to your temporary table, and cut them off with a hacksaw. Make sure you're using a sharp blade. While you're setting up the clamps,. The hacksaw will often damage the last thread when it cuts. Running a nut off the end will fix this. You'll have to run the nut all the way down from the other end.

This doesn't take long, if you chuck up the rod in your drill and let it do the work. Hold the rod vertically, with the drill pointing down, and just hold on to the nut enough to keep it from spinning.

Assembly When you have the rods cut to length, put everything together the way you did before, and you'll have your first trestle. Repeat the same process for the second trestle, and then for long stretchers to assemble the base Once the stretchers and legs have been connected, flip the assembly upside down, and install the levelers.

Then flip it back upright. Next is the shelf. Start with the 24x48" piece of MDF. Clamp this on top of the base, and pencil in the outside of the stretchers and the inside angle of the legs.

Flip it over, pull out your trusty cutting guide, and cut it to width and to length. Cutting out the angles is simple, with a jig saw. It's not much work with a hand saw. If you took enough care with supporting blocks and stops, you could probably do it with a circular saw. Since I did have a jig saw, I used it.

I'd decided on an oil-and-wax finish. Oil finishes are by no means the toughest. In fact, they're really rather pathetic, so far as protecting the wood goes. But they're easy to apply, and not even the toughest finish will stand up to the abuse that a workbench will suffer, so it's more important that it be easy to repair.

Wax is usually used to add a high gloss. On a bench, it's there to keep glue from sticking. And then decided that the oil alone would be sufficient for the base. The wax serves to give the surface a gloss which I see no need for , and to make it easier to remove spilled glue and paint which I also see no need for, on the base. So I oiled the base and oiled and waxed the top.

The "Getting Started in Woodworking" video series has an episode on applying oil-and-wax finishes, that includes steps such as wetting the wood, and then sanding down the raised grain. All of this seemed excessive, for something that I was going to put in my basement and bang on with a hammer. I made a low table out of a couple of step-stools, my hollow-core door, and one of the MDF panels that would eventually form part of my top.

I was concerned that any oil that dripped on the door might interfere with its glue adhesion, when I finally get around to the project for which I'd purchased it. The top side of the top sheet of MDF, though, I planned to oil, anyway.

Ditto for the bottom side of the bottom sheet. Putting the base up on this temporary table put it an a more convenient height than it would have been on the floor or on a full-height table. Applying the oil is easy. Put on some vinyl gloves, pour some oil in a bowl, take a piece of clean cotton cloth the size of washcloth or smaller, dip it in the oil, and apply it to the wood. You want the wood to be wet. Apply oil to the entire surface, and then go over it looking for dry spots, applying more oil as needed.

After fifteen minutes of keeping it wet, let it sit for another fifteen minutes. Then apply another coat of oil, and let it sit for another fifteen minutes. Rub it dry. Wait half-an-hour, and then wipe dry any oil has seeped out. Check it every half hour and do the same, for a couple of hours. The next day, apply another coat, wait half an hour, then wipe it dry. Do the same on successive days for as many coats as you think are necessary.

I applied three. Remember those fire safety tips you used to get in grade school, about the dangers of oily rags? It was linseed oil they were talking about.

All oily rags are dangerously flammable. Linseed oil will self-combust. Linseed oil doesn't evaporate, it oxidizes. The oxidization generates heat, and the increased temperature increases the rate of oxidation. Linseed oil sitting in a bowl, or spread on the surface of wood, is perfectly safe.

But a linseed oil soaked rag provides a vastly increase surface area, so the oxidation happens faster, and the rag can provide insulation, trapping the heat. The increased temperature speeds up the oxidation even more, which raises the temperature even more, and the runaway feedback can quickly result in temperatures that will cause the rag to spontaneously burst into flame.

This isn't one of those "do not drive car while sunscreen is in place" warnings. This is one of those "keep your finger off the trigger until you have the gun pointed at something you want to shoot" warnings. Rags soaked in linseed oil will catch fire, if you don't handle them properly, and they can do so far more quickly than you might think. Hang them up outside, away from anything combustible, and where there's enough air circulation to keep them cool.

Or put them in a bucket of water, and hang them outside later. If you're just setting a rag down for the moment, set it out flat, without folds, on something non-flammable. Hanging outside in the breeze, the oil in the rags won't retain heat while they oxidize. For the oil to completely oxidize can take in a couple of days, if it's warm, or more than a week, if it's cold and rainy.

When fully oxidized, the oil will be solid and the rags will be stiff. At that point, they're safe, and can be thrown in the trash. Toss them in the trash before that, and you might as well say goodbye to your garage. Before you start cutting or drilling the pieces that will make up the top, determine the layout of the top. This should include the dimensions of the MDF, the dimensions of the edging, the locations of the vises, and of the screws or bolts that will support the vises, and of all of the benchdog holes and of all of the drywall screws you will use to laminate the panels, If you don't lay it all out in advance, you could easily find that you have a bolt where you need to put a benchdog hole, or something of the sort.

I sketched out ideas on graph paper, then drew the plan full-size on the top side of the bottom layer of MDF, using the actual parts as templates. The width of the top is determined by the width of the base. The length of the top depends upon the vise or vises you uses. The end vise I had purchased was intended to be used with hardwood jaws that extend the width of the bench.

I had a piece of 2x6" white oak I intended to cut down for the purpose. The decision to be made with respect to the end vise is whether the support plate should be mounted to on the inside or on the outside of the stretcher. Mounting the plate on the inside of the stretcher reduces the reach of the vise - it can't open as far, because the support plate is back from the edge by a couple of inches.

But mounting the plate on the outside of the stretcher means that we need to add some support structure for the inner jaw of the vise, which the legs would have provided if we'd mounted the plate on the inside.

I mocked up the two scenarios, and determined that with the plate inside the stretcher the vise would have a reach of 8 inches, and with it outside the stretcher it would have a reach of 9 inches. I decided that 8 inches was enough, and that the extra inch wasn't worth the extra effort.

With the end vise mounted like this, the right edge of the top would have no overhang. I wanted the left edge of the jaw of the front vise to be flush with the left edge of the top, the right edge with the left edge of the left front leg.

So the amount of overhang on the left depends upon the width of the front vise jaw. The width of the jaw is, at a minimum, the width of the plate that supports it, but it's normal to make the jaw extend a bit beyond the plate. How far? The more it extends, the deeper a bite you can take with the edge of the vise, when, for example, you are clamping the side of a board being held vertically.

But the more it extends, the less support it has. What you need to determine, by this drawing, is where you need to drill the dog holes, the mounting holes for the vises, and where you will put the drywall screws you'll be using for the lamination.

As well as where the edges of the top will be cut. The next step is to laminate the two sheets of MDF that will make up the lower layers of the top. First, trim the MDF to slightly oversize. You'll want room to clean up the edges after the pieces are joined, but you don't need more than a half-an-inch on each side for that, and there's no point in wasting glue. If you're lucky enough to have a vacuum press, use that.

Otherwise drill holes for the screws in the bottom layer at all the points you had indicated in your layout. You'll also want to either drill a row of screws around the outside edge, in the bit you're going to trim off, or you'll need clamps all around the edge. I just added more screws. The screw holes should have sufficient diameter that the screws pass through freely. You want the screw to dig into the second layer and to pull it tight against the first.

If the threads engage both layers, they will tend to keep them at a fixed distance. If you're using drywall screws, you'll want to countersink the holes. Drywall screws are flat-head, and need a countersink to seat solidly. If you're using Kreg pocket screws, the way I did, you won't want to counter-sink the holes.

Kreg screws are pan-head, and seat just fine against a flat surface. Both drywall screws and Kreg pocket screws are self-threading, so you don't need pilot holes in the second sheet of MDF. Regardless of which type of screw you use, you'll need to flip the panel and use a countersink drill to on all of the exit holes.

Drilling MDF leaves bumps, the countersink bit will remove them, and will create a little bit of space for material drawn up by the screw from the second sheet of MDF. You want to remove anything that might keep the two panels from mating up flat. I set a block plane to a very shallow bite and ran it over what was left of the bumps and over the edges.

The edges of MDF can be bulged by by sawing or just by handling, and you want to knock that down. After you have all the holes clean, set things up for your glue-up.

You want everything on-hand before you start - drill, driver bit, glue, roller or whatever you're going to spread the glue with, and four clamps for the corners. You'll need a flat surface to do the glue-up on - I used my hollow core door on top my bench base - and another somewhat-flat surface to put the other panel on. My folding table was still holding my oak countertop, which makes a great flat surface, but I want to make sure I didn't drip glue on it so I covered it with some painters plastic that was left over from the last bedroom we painted.

Put the upper panel of MDF on your glue-up surface, bottom side up. Put the bottom panel of MDF on your other surface, bottom side down. The panel with the holes drilled in it is the bottom panel, and the side that has the your layout diagram on it is the bottom side. Chuck up in your drill the appropriate driver bit for the screws your using. Make sure you have a freshly-charged battery, and crank the speed down and the torque way down.

You don't want to over-tighten the screws, MDF strips easily. Once you start spreading glue, you have maybe five minutes to get the two panels mated, aligned, and clamped together. So make Countersink Drill Bit Lowes Jar sure you have Countersink Drill Bit Lowes Meaning everything on-hand, and you're not gong to be interrupted. Start squeezing out the glue on one MDF panel, and spreading it around in a thin, even coating, making sure you leave no bare areas.

Then do the same to the other MDF panel. Then pick up the bottom panel and flip it over onto the upper panel. Slide it around some to make sure the glue is spread evenly, then line up one corner and drive in a screw.

Line up the opposite corner and drive in a screw there. Clamp all four corners to your flat surface, then start driving the rest of the screws, in a spiral pattern from the center. When you're done, let it sit for 24 hours.

The edges of MDF are fragile, easily crushed or torn. MDF is also notorious for absorbing water through these edges, causing the panels to swell. This edging is one of the complexities that Asa Christiana left out in his simplified design. I think this was a mistake. MDF really needs some sort of protection, especially on the edges. Of course, I, on the other hand, with my Ikea oak countertop, Countersink Drill Bit Lowes Code probable went overboard in the other direction.

I clamped the countertop to my bench base, and used the long cutting guide. I'd asked around for advice on cutting this large a piece of oak, and was told to try a Freud Diablo tooth blade in my circular saw. I found one at my local home center, at a reasonable price, and it worked very well. Remember, you want the width of the top to match the width of the base, and you're adding edging.

First, cut one long edge. Second, cut a short edge, making sure it's square to the long edge you just cut. Finally, cut the remaining short edge square to both long edges. The length of the top doesn't need to precisely match anything, so we don't need to bother with clamping the trim before measuring. Glue up the trim on the end, first. Do a dry fit, first, then as you take it apart lay everything where you can easily reach it as you put it back together again, after adding the glue.

To help keep the edge piece aligned, I clamped a pair of hardboard scraps at each end. I used the piece of doubled MDF I'd cut off the end as a cawl, to help spread the pressure of the clamps. Squeeze some glue into a small bowl, and use a disposable brush. As you clamp down, position the trim just a little bit proud of the top surface.

Once you have all the clamps on, take off the scraps of hardboard. You can clean up the glue squeezeout with a damp rag.. When the glue is dry, trim down the strip flush with the panel using a router and a flush-trim bit. Then cut off the ends of the strip with a flush-cut saw, and clean up with a block plane, an edge scraper, or a sanding block.

Leaving the ends in place while you route the edge helps support the router. The strips along the front and back edge is glued up the same way. I suppose you could try to glue both on simultaneously. I didn't try. When the top is done, we want the edged MDF and the oak countertop to have exactly the same dimensions, and for their width to exactly match the width of the base.

I could see three ways of doing this: 1, join the MDF to the countertop and use my belt sander to sand down their joined edges to match the base; 2, join the MDF to the countertop and use a hand plane to plane down their joined edges to match the base; or 3, use a flush-trim bit against a straight edge to route the MDF to the width of the base, then join the MDF to the countertop and use the flush-trim bit to route the countertop to match the MDF.

So I chose option 3. If you choose the same, you want to trim the edges of the MDF layer prior to joining it to the countertop. In other words, now. Put the MDF on the floor, bottom up. Flip the base and place it on the MDF. Line up the base on the MDF in the posiiton you feel best, then mark the position of the legs. Sorry, I have no picture of this. Flip the base upright, put the MDF on top of it, then use a straightedge to draw two straight lines joining the outside edges of the legs and extending the width of the MDF.

I used the countertop as the straightedge. Use a carpenter's square to transfer these lines onto the ends of the MDF. Put the countertop on the base, put the MDF on top of the countertop, and line up the marks you drew on each end of the MDF with the countertop below it. I clamped a couple of scraps of doubled MDF at each end to give the router base something extra to ride on at the ends.

Edge-trimming endgrain can result in tearout at the right side, so route the short edge before you route the right long edge. Routing the right edge can then clean any tearout that occurs on the short edge.. When gluing the oak edges on the MDF, I made a mistake. On the back side, the edging was positioned too low, which would leave a noticeable gap when the MDF and the countertop were joined.

I was determined to fix it. Either of the strips I'd ripped from the oak countertop to remove the factory bevel looked like it would work, if I could figure out how to rip them safely with a circular saw.

I ended up using a couple of strips of MDF and a bar clamp to create a clamp that would hold the strip of oak, and had a profile low enough to fit under the cutting guide. Once I had the strip cut, I glued it in place, and clamped everything up.

I'd intentionally made it oversize, intending to trim it flush. Trimming is a little more complicated than usual, because I needed to trim it flush on two faces.

Aside from the use of the edge guide, flush trimming the edge face was unremarkable. For trimming the top face, I again stood the panel vertically, with the router base riding on the top edge, and the bit cutting on the far side of the panel. Because I was cutting on the back edge of the work piece, I needed to move the router from right to left. And here I ran into another problem. The gap in the edging that I was filling was not of even depth.

That means that on the right side, I was routing away all of the strip I had glued in. The result was significant tear-out. I did what I always do when faced with this sort of gumption trap - I turned off the router, set it down, and walked away for a bit.

I've found that whatever action I take in the frustration of dealing with something that hadn't worked right is almost always the wrong one, and usually makes things worse.

What I did, when I came back, was to clamp down the strip where it had torn away, and then to start routing from the other end. I still moved the router from right to left, but I did it in six-inch sections, taking light passes, and sort of whittled the strip flush. As the sections I was working were farther to the right, the strip was thinner.

Eventually I came to where I was trimming the strip away entirely, at which point I took off the clamps and the remainder fell away. A better solution would have been to route a rabbet into the side, so that the added strip always had thickness.

The way I did it means that the strip I glued in is very narrow, and hence very weak, at a certain point. In this case, that's not a problem, because it's going to be sitting under the countertop layer. I also noticed that because I had only clamped the strip down, and not into the edge, there was a noticeable glue gap where the strip butted up against the MDF. Again, in this application it isn't visible. But if I was doing something like this on the top of a table, I'd make sure to cut a clean rabbet, and to clamp both down and in.

So while for the end vise, if we mount it lower, we can make both the jaws deeper to compensate, for the front vise we cannot, so we want it mounted as close to the edge of the bench as possible.

It's usual to attach vises with lag screws from the bottom, but there is a limit as to how many times you can tighten up a lag bolt in MDF. I decided to use bolts from the top down, embedding the heads of the bolts inside the top. First step was to cut a piece of MDF the size of the base of the vise.

I scribed the positions of the bolt holes in it, then driilled small pilot holes. I also drilled larger holes at the corners of the rectangular cutouts, and the joined them with a jigsaw.

Then I flipped the top and the base, lied up the base in the proper location relative to the top, I then positioned the front vise and the support MDF for the end vise, and marked the locations of the bolt holes.

Then I flipped the base right side up, drilled small pilot holes from the bottom side where I had marked the locations, and then drilled shallow countersink holes from each side, then a through hole that matched the bolts.

Finally I tried out the bolts and washers, and deepened the countersinks until the heads of the bolts were just below flush. With the holes and countersinks in place, I inserted the bolts, used tape to keep them from falling out, flipped the top, applied glue to the support piece of MDF, fit it over the bolts, added washers and nuts, and tightened it down.

The reason I'd cut out the rectangles in the vise support was that I'd intended to put a benchdog hole through each, and I wanted the thickness of the top to be the same for all of the benchdog holes. Where I messed up was in not cutting out the ends, between the bolt tabs. I'd intended to put a benchdog hole through there, as well, but I'd forgotten to cut out the segments prior to glue0up.

No matter, It was only twenty minute's work to route out the areas flush with the top,. You'll want to get as much done on each of the two layers of the top separately, before we join them, because handling the top after the two layers are joined is going to be a major hassle.

So drill the benchdog holes through the MDF layer. Begin by laying out their positions. You'll want these to be precise, so that the distances between the holes are consistent. The vises you are using will constrain your benchdog spacing.

My front vise worked most naturally with two rows of holes four inches apart, my end vise with two pairs of rows, with four inches between the rows and eight inches between the pairs.

Because of this, I decided on a 4" by 4" pattern. I lined up the template, and drilled a second hole, then put another bit through that. From then on, I worked entirely from the template. With two bits through the holes pinning the template in place, the other holes in the template would be precisely located or so the theory goes on a 4x4" grid.

Having done all this, I'm not sure I'd do it this way again. It might well be faster to layout the positions with compass and straightedge directly onto the top. Either way, you'll want to use a scribe rather than a pencil. Scribe lines are hard to see, and impossible to photograph, but the scribe and compass points click into them, allowing a precision that pencils simply cannot match. Once you have all the positions marked, drill them through.

Drilling this many holes in MDF burns up bits. You're going to need to either buy several bits or learn to sharpen them. Forstner bits produce holes with cleaner edges than spade bits, but they cost more and they're more difficult to sharpen.

With my layout, I needed to drill 52 precisely located holes. I didn't get every one of them right. If you should drill a hole in the wrong position, if it doesn't overlap the correct position you can just ignore it.

If it does, you'll need to fill it. So I had to paint an odd number of rungs in bright colors — he would probably have preferred that I get three custom colors just for this but instead I used paints I had left over from other projects.

Balance however many dowels you choose to paint across the sawhorses, leaving the ends floating. Do a dry fitting to make sure your dowels all fit in the holes.

Ideally the dowels will lift easily in and out but a tight fit is OK as long as the dowel does go all the way to the bottom of the hole on the dry fitting as the glue will lube things up. For my prototype I came up with what I thought was a pretty nifty method to screw the dowels into the side rails. But if you want the extra security — maybe you have very heavy kids? Now put a dowel into each hole and tip the whole lot over so the unit is standing on the dowels on the floor and the side rail faces up.

Neat, huh? As described in Option A, drill a pilot hole through the divot left by the forstner bit in the two holes at the top of each of your long side rails ONLY so, four holes total.

Put a small amount of wood glue into each of the holes on one long side rail. Use your finger to spread the glue up the sides of the hole, which will help provide lubrication in case any of your dowels are a tight fit. Place a dowel in each hole and hammer each one with a rubber mallet to seat them. Working quickly, glue each of the holes on the other side rail of the same length. Make sure the tops of your side rails are facing the same way.

Place the second side rail over the dowels, coaxing them into the holes. Whichever method you used, complete the short ladder in the same way, except that you screw into all holes if you used the screw method. I didn't want to assume that you had access to anything other than a cheap household printer; sorry that this requires assembly of the template pieces. Use the point of a screw or drill bit to poke through and mark the holes labeled A and B ONLY do this first in case the template comes loose during cutting , and then use the band saw to cut out the shape.

Check for fit by aligning the Pivot Piece with one of the long side rails the end with the holes in. Do the contours of the Pivot Piece follow the side rail? Does it look like the hole markers are centered over the dowels? Put at least 3 coats of polyurethane on the two ladders and on the Pivot Piece.

This can be time-consuming because of all the nooks and crannies. After you finish a coat, go back over it again and brush away any drips. I suppose you could suspend each ladder from the ceiling and do a complete coat at once; if you lay it down you generally have to flip it back and forth from one side to the other to complete half a coat at a time.

Screw the Pivot Piece to one of the long side rails through the two holes. I set the screws so they're just sticking out of the bottom of the pivot piece, which helps me to locate the holes in the side rail. When the screws are in it should feel pretty solid. Do the same with the other Pivot Piece on the other side of the long ladder.

Set the long ladder down so one Pivot Piece is on the floor and the other is parallel to the floor. Slide some spacers left wood from cutting out the Pivot Pieces — one under the Pivot Piece and two under the side rail of the ladder.

Ease the drill bit in gently toward the end to avoid splintering on the Pivot Piece. Stop when you feel air followed by concrete Flip the unit over and countersink the hole on the pivot piece side only no need to countersink the side rail. Slip a bolt into the hole and install a locking nut. Now line up the second side of the short ladder in the same way that you did the first and make another bolt hole and install the second bolt.

Exact placement is not critical as long as you go through the Pivot Piece at some point, but I put mine half way between the top two rails. Again, ease the bit in gently to avoid splintering on the Pivot Piece. If you do get splinters as I did you'll have to trim them with a chisel as you won't countersink this hole. Exact depth is not critical but make it somewhere between the depth of the tee nut and the width of the side rail.

Flip the unit over and do the same on the other side. Insert a tee nut into each of the holes in the side rails and tap them down with a hammer if needed. Screw the thumb screw in from the outside of the Pivot Piece. It does take a fair bit of screwing to seat it but it does the job. Question 4 months ago on Step What is the measurements on the triangle pieace??

I thought I saw a drawing, but now I cant find it. I am going to finish mine with a non-toxic oil finish. You know baby is going to mouth those rungs. Better using a nice oil finish than feeding the kid paint. Even a non-toxic paint strikes me as less benign than a linseed oil.

Reply 5 months ago. I realize this comment was two years ago and you may well have already known the difference , but before anyone else tries it, it's important to note that common hardware store boiled linseed oil uses an assortment of really nasty drying agents that are the opposite of non-toxic.

Think "heavy metals" - and we're not talking Manowar here. You might not want to expose your baby to Manowar either, but it's probably less harmful than lead and cobalt. I haven't used them, but there do seem to be some versions of BLO that are formulated explicitly to be non-toxic - you'll have to shop carefully for them, though.

Raw linseed oil, on the other hand also sold as flaxseed oil is safe They're more expensive, but McMaster doesn't have a minimum order. As for the purpose, I'm not positive and I hope someone else can correct me on this but it looks like it acts as a release pin to fold up the triangle.

Someone else recommends hitch pins for what I believe is the same purpose. You can find less expensive but top quality birch dowels through Amazon. No stores in my country have any 1" dowels right now.

Question 9 months ago on Step Tip 12 months ago. Made it! If you made mistakes like I did, you should adjust the templete. Reply 9 months ago. Hiya, how did you have to alter the template for the top triangle piece for metric? I'm working with metric too. My dad made us one and used U shaped hitch pins. Reply 11 months ago.

Question 1 year ago on Introduction. If so what is the scale or actual size.. Thanks so much for posting this and your time in answering my question. Answer 1 year ago. The template is in Step 1, under the special equipment section at the end. It' a separate download. Took me a minute to find it as well. Question 1 year ago on Step 8. Tip 1 year ago on Step 6. I like to keep it simpler than simple.
