The objective of sanding wood is to remove mill marks, which are caused by woodworking machines, and to remove other flaws such as dents and gouges that may have been introduced in handling.
The most efficient method of doing this is to begin sanding with a coarse enough grit of sandpaper to cut through and remove the problems quickly, then sand out the coarse-grit scratches with finer and finer grits until you reach the smoothness you popular woodworking bench plans — usually up toor grit.
This is a very important concept because it gets past all the contradictory instructions about which sandpaper grits to use. Conditions vary. For example, a board that has been run through a planer woodworkinng dull knives will require a coarser grit to be efficient than typical veneered plywood or MDF that has been pre-sanded in the factory. You can finish-sand both of these surfaces with grit, for example, wlodworking you might begin with 80 grit on the solid wood and grit on the plywood.
It woodorking be woodowrking total waste of time and effort to begin with 80 grit on the pre-sanded veneered wood and you would risk sanding through.
Sanding is very personal. We becnh sand with different pressures, number of passes over any given spot and lengths of time.
Unquestionably, popular woodworking bench plans most efficient progression is to sand through every grit — 80,— sanding just enough with each to remove the scratches of the previous grit.
Film-building finishes, such as varnish, shellac, lacquer and water-based finish, create their own surfaces after a couple of coats. The appearance and wopdworking of the finish is all its own and has nothing any longer to do with how fine you sand the wood.
But these finishes can be made ultimately smooth simply by sanding between cured coats or sanding each additional coat while it is still wet on the surface using or grit sandpaper. Fine sanding. Sanding finer than or is wasted effort in most cases, as explained in the text. In fact, the finer the grit the wood is sanded to, the popular woodworking bench plans color a stain leaves when the excess is wiped off.
In this case, the top half was sanded to grit and the bottom half to grit. Then a stain was applied and the excess wiped off. The finer you sand, the less stain color will be retained on the wood when you wipe off the excess. If this is what you popular woodworking bench plans, then sand to a finer grit.
Sanding by hand in the direction of the grain to remove these squigglies then becomes unnecessary. Random-orbit sanders are more efficient than vibrator sanders, but they still leave cross-grain marks in the wood.
Doing this is especially important if you are staining. Of course, doing this is seldom possible on turnings and decorative wooworking patterns such as sunbursts and marquetry. Sanding cross-grain tears the wood fibers so the sanding scratches show up much more, especially under a popular woodworking bench plans. The best policy is to always sand in the direction of the grain when possible. The scratching that does occur is then more likely to be disguised by the grain of the wood.
You should practice first on scrap wood to determine where this point is for you. Other than using a stationary sanding machine or a belt sander, which will take a good deal of practice to learn to control, there are three methods of sanding wood: with just your hand backing popylar sandpaper, with a flat block backing the sandpaper and with a vibrator or random-orbit sander.
Using your hand to back the sandpaper can lead to hollowing out the softer early-wood grain on most woods. Sand with the folded sandpaper until it dulls, flip the folded sandpaper over to use the second third, then refold to use the third third. If you are sanding critical flat surfaces by hand, you should always use a flat block to back the sandpaper.
I find the rubber sanding blocks, available at home centers, too hard, wasteful of sandpaper and inefficient because of the time involved in changing sandpapers. I made my own sanding block. Any wood will work. I popular woodworking bench plans sugar pine because it is very light in weight.
To get the most efficient populad of the sandpaper, fold one of the thirds-of-a-sheet in half along the long side and hold it in place on the block with your fingers and thumb. When you have used up one side, turn the folded sandpaper and use the other. Then open the sandpaper and wrap it around the block to use the middle. Most woodworkers use random-orbit sanders because they are very efficient, easy to use, woodwokring they leave a less-visible scratch pattern than vibrator sanders due to the randomness of their movement.
For both of these sanders, however, there are two critical rules to popular woodworking bench plans. Pressing leaves deeper and more obvious squigglies that then have to be sanded out. Simply move the sander slowly over the surface of the wood in some pattern that covers all areas approximately equally.
Use a popular woodworking bench plans block to back the sandpaper if you are sanding a flat surface. No matter which of the three sanding methods popular woodworking bench plans use, always remove the sanding dust before advancing to the next-finer grit sandpaper.
The best tool to use is a vacuum because popular woodworking bench plans is the cleanest. A brush kicks the dust up in the air to dirty your shop and possibly land back on your work during finishing. Tack rags load up too quickly with the large amount of dust created at the wood level. These sticky rags should be reserved for removing the small amounts of dust after sanding between coats of finish. Popular woodworking bench plans air works well if you have a good exhaust system, such as a spray popular woodworking bench plans, to remove the dust.
The biggest sanding challenge is to know when you have removed all the flaws in the wood and then when you have removed all the scratches from each previous grit popular woodworking bench plans you can move on to the next. Being vench that these flaws and scratches are removed is the reason most of us sand more than we need to. A lot of knowing when you have sanded enough is learned by experience. But popular woodworking bench plans are two methods you can use as an aid.
First, after removing the dust, look woodworoing the wood in a low-angle reflected light — for example, from a window or a light fixture on a stand. Second, wet the wood then look at it from different angles into a reflected light. For wetting the wood, use mineral spirits paint thinner or denatured alcohol.
Avoid mineral spirits if you are going to apply a water-based finish because any oily residue from the thinner might cause the finish to bead up.

I really find them to be very helpful for my new projects. Wonderful well-research work. This is an excellent entry level sanding article! Kudos to Bob! By Bob Flexner. In Techniques.
