cut-perfect-circles-in-wood-on www.- shows you how to cut a perfect circle or an oval with a router and a special jig.  Drill Holes in the Wood Block. The second jig for cutting curves and circles with a router can be made from scraps that are around the workshop. Like the jig described above, it's attached to the router's sub-base. Drill holes the same size as the dowels into one long edge of the 12" x 1x4 wood block. The holes should be as far apart as the diameter of the router's base. Step 7. sand tips of dowels. Circle-Cutting Router Jig. All three of the previous techniques rely on having to buy a special bit or saw for each size hole you need to cut. This can get pricey. And what if you need to cut a really large hole, say 10” in diameter?  Like everything else in woodworking, there are options for every task. These are my favorite ways to cut perfect holes in wood. Mostly I want to emphasize that you can accomplish just about any woodworking goal with modest tools. My advice is always to buy a new tool or upgrade what you have only when you simply can’t accomplish something with what you have. No top-level wood ID, low effort, or price queries. Use a proper descriptive title. Buy some /r/woodworking!  I cut a perfect circle in about three minutes, with very little effort. Hard to be more efficient than that, eh? permalink.  Much less dangerous. Although a perfect cut on a band saw is nearly impossible, the blade can flex. There are better and safer ways to get a circle, but this can be an inexpensive way to do it. permalink. embed. I use double sided tape to stick the workpiece to a scrap piece of plywood otherwise when you cut through you could have flying bits. A jigsaw is a portable tool guided, free-hand to cut whatever shape or curve you want relatively quickly. Please dont forget to follow Banging Toolbox on. Once the work is roughed out, the danger of binding is little as the cut perfect circles in wood on is not embedded in the work. Lay the Dowels on the Sides of Router Place the dowels through the holes on the sides of the router's base. Using push pads to protect your hands, rotate the blank clockwise into the blade in order to shave and sculpt it into a perfect circle. For small circles I sometimes use hole saws lol.

Of course, everyone knows that a table saw pushes back on the work, and that the work can jam against the blade, especially if the fence and blade are not set parallel, or the wood has locked-in stresses. When the work is a many-sided polygon, pinned at its center, any backward rotation will cause a jam against the blade, VIOLENTLY kicking back the work and sled, and possibly leading to fingers contacting the blade!

I wouldn't even THINK about doing this without a guard in place, setting the blade as high as possible to minimize the pushback tendency , and setting the guard as low as possible to just clear the work.

Setting the blade high also gives truer cut when you get to the final "spin" pass. Your comment about bandsaw being limited in radius is true only to the extent you don't have room off to the side of the table. You can precut the corners off until you are less then that.

You must set the pin carefully, accounting for the "lead" or cutting direction, or the blade will be pulled to the side, and produce a spiral and then jam. Use a blade with a high tooth set. Avoid "thin kerf" blades. Set guides close and keep blade tension high. Another method to make circle is to first make template from scrap using your's or other methods , fastening this to the work, and using router with follow-bearing against the template.

Reply 3 months ago. I don't understand your concern about a hidden danger with the table saw method, unless you're basing it on trying to trim too aggressively on the final rounding pass. If that trim pass is taking off little more than the width of the blade, there's no chance of kickback. An advantage for the table saw is the relatively large supporting surface versus the small table of ordinary bandsaws, which makes it easier to get a square edge.

You state that you are "uneasy" about the table saw setup. When wood binds against the blade, it is pushed back. With usual table saw arrangement wood getting pushed directly in, fence parallel to the blade , backward motion tends to relieve the bind, and there is no tendency for the work to rotate because the binding force is in line with the pushing force.

But in your setup, the wood piece is pivoted about the center point of the circle, which is laterally offset from the blade, and connected to a massive sled.

If the work binds the blade suddenly, the inertia of the sled will resist moving back. The offset force will cause the work to rotate about that pivot, toward the blade, causing the bind to Cut Perfect Circles In Wood Quotes get tighter, contacting the blade in the back.

The only thing preventing this is the friction between the work and sled and your holding blocks, which is no match for the saw. The work will lift, and it and the sled will be shot back! Once the work is roughed out, the danger of binding is little as the blade is not embedded in the work.

For all of the cuts, setting the blade as high as possible reduces the amount of pushback, and keeping the cuts short so the back side of the up-moving blade is not contacted geometry more like the bandsaw setup.

Having a guard in place "protects" the high-set blade and prevents the work from lifting. The high setting also makes the sled position easier to determine, and the final spin-cut truer.

I hope you have Saw Stop on that saw! I don't think you intended the last comment as a reply to mine, but I agree that setting the blade high is important. I had to cut a circle for the well about a year ago, two pieces of plywood with poly insulation in the center. That was not fun cutting by freehand lol. Great tips, thank you for sharing! Thanks for sharing. For large circles I have used 2 dowels and one end has a rounded tip and the other I tape a marker on and use it like a giant compass and a hand held jig saw.

However, now that I have a large laser cutter - I am spoiled: It is just so easy to draw it and send it to the laser:. Reply 4 months ago. I agree, unfortunately I am not spoiled, so I use less or more what you suggest with hand held jig saw. For small circles I sometimes use hole saws lol. But you must have the right size of course, secondly there will be a drill hole left in the center. Tip 4 months ago on Introduction.

I like the router method, even for its mess - with a router you can also cut perfect large round holes. Years ago I needed holes to flush mount audio speakers, and a router was really the only practical way to get the two holes perfect On your router circle jig, try mounting a cord clip to keep from running over the cord. Maybe add a large hand on the small end to give you better control on the jig. Thanks, Mike Ironworxx Guitars. Just a question?

Your methods are well explained and would make creating circles much easier. But do you have a method of cutting a circle in a piece of wood where the circle is NOT the object to be used. My daughter was asking me minutes before I saw your Instructables on creating circles easily with power tools. She wants to build a dog food bowl stand and wanted to know the best way to remove the wood so the bowls will be inserted in the shelf.

Close is good enough for horseshoes, hand grenades and dog bowls. The bowls will have to have a LIP, right? The width of the lip covers a multitude of wavering. Use a jig saw if you've got one.

Determine the diameter required. Then use half that and a compass with a pencil to mark out the circle representing the hole required by the bowl. First drill a hole larger than the jigsaw blade somewhere inside the diameter of the hole required. Then drop the jigsaw blade into this hole and cut along the line you drew for the diameter of the hole required. Pop in the bowl to be sure of your fit, then assemble the top onto some supports to raise the affair to a height bowser finds most convenient.

Finsidh to suit daughter or puppy - or leave au natural as I did. However, a cordless model still has sufficient power for almost all jobs with added versatility and portability. A Makita or Dewalt 20v jigsaw is a great cordless choice for cutting circles in wood, metal, tiles, and plastic.

Depending on the thickness of wood you are cutting you would need to do the cut in multiple rounds, to avoid the router from being over-worked. It is a bit of a complicated set-up to just cut a simple circle. But as the video from YouTube below shows, you could even use this technique to cut circle patterns as well as a full cut.

A band-saw is another way to cut circles in wood if the material is small enough to be lifted onto the band-saws table. Band-saws are not the cheapest or easiest way to cut circles in wood however they are a good way to cut thicker Cut Perfect Circles In Wood Jacket gauged metal projects if you know someone that will let you use theirs.

Band-saws have more grunt and less blade flexibility than a jigsaw, making them more ideal for more heavy cutting jobs. But they are not cheap or portable like an electric jigsaw tool, making band-saws only suited for commercial workshops. After you have picked a circle cutting tool for your job you want to mark-out the cut-out. The best way to mark out a circle is to first mark the center.

Next, you want to tie a piece of string to the tip of your pencil and cut the string to the length that you want the radius to be. You can then attach the string to a screw in the middle and you can now use the string to guide your pencil to perfectly mark your circle on your wood, plastic, or metal surface.
