A miter saw is nothing without a firm surface to make cuts on. A miter saw stand is one of the more expensive pieces of equip that a carpenter can have, and it’s in your interest to save money on one if you can.
The best way to do this is to construct one yourself. One of the biggest hassles of not having a stand, is trying to cut long pieces of wood. When you’re making a cut on a very long piece of wood, without proper support, it moves all over the place. This results in awful, messy cuts that just don’t look professional. In order to mitigate this, you can construct your own miter saw stand. The standard design for this is called a miter box, and has specific measurements that are an industry standard. First, you need hangar bolts with a matching nut, by measuring the table height and adding about two inches. Start with the wood by making a 15 and five eighths inch wide piece for the bottom, and a 16 inch wide strip for the top. The cuts don’t have to be perfect, but accuracy helps. Cut the 15 and 5/8 piece into 6 different pieces, these will make up the dividers. Ensure that they are at least 3/8 inch thick when you’re done cutting. Set up all the dividers next to the saw when you’re done. Then, set all the dividers equally on the base of the board. When you’ve done this, place your miter saw in the center. This will be the location of your miter saw bay. When you’ve done that, size the spaces to the size of the miter saw, and ensure that they are still equally divided from each other.
Following that, go to the underside of the base, and screw in all the dividers so that they are firmly attached to the base of the miter saw stand. Next, place your miter saw in the miter saw bay, and then secure clamps to it. This is so that the miter saw can not move while in operation, and the clamps ensure that this won’t happen. There’s nothing worse than having the saw slip while you’re trying to make a straight cut, and this will help to avoid that. After that, you’re going to want to cut two 1x4s to the size of the left side, on the top. Then, use what’s left to cut four triangularly shaped braces. Add the braces to the new cuts via screws, then start to screw the new “fence” to the edge of the dividers. This will help when you’re making continuous cuts of wood that have similar dimensions. Then, rest the entire miter saw box on either a sawhorse stand, or something of similar make. The important point is to have the miter saw box be flat and firm, and have enough weight bearing to be able to support both the miter saw, as well as any wood you might be cutting on it.
