A miter box is used to make 45-degree cuts and 90-degree cuts in wood, often used for trim or frames. Place a piece of scrap wood in the bottom of a miter box to prevent damage with tips from a remodeling contractor in this free video on home repair and maintenance.
Okay, hi, I'm Tim Gipson and I'm going to talk to you about how to use a miter box. In this case this is just a standard miter box that you can pick up any home improvement store or hardware store and I have mounted it to a piece of wood, scrap wood just to give it some stability to work with. Then I am using it on a work surface with a carpet pad. Now this allows you to set it down and be able to work on an area without it sliding around on you. Now with a miter box we can make forty-five degree cuts or ninety degree cuts for cutting trim, things for, such as making picture frames or trim around the house. When we're using our miter box it's a good idea to take a thin piece of scrap wood and place in the bottom. This will allow you when you're making your cuts, it will keep you from cutting into your miter box and allow you to make better use and keep your miter box usable over a longer period of time. Now we're getting ready to make our ninety degree and we mark our trim where we want to cut, then we just want to line up our mark with the edge of the miter box and then you want to use a back saw. The back saw what it does, it actually cuts on a forward motion, but these are specifically designed to work with a miter box. Then what we want to do is we want to just follow the miter box, make short smooth cuts. So short smooth cuts you can see gives us a very good forty-five degree angle. When we cut our other pieces, it gives you a very good job, joint. With a little bit of sanding, that makes a perfect ninety degree angle. Again, we can also use this with a straight cut to cut off and then we've got a side bevel for forty-five degree, so if you have wider pieces that you need to lay down, you can also cut from that angle. So I'm Tim Gipson and that's how to use a miter box.
