Baseboards, picture frames, boxes and more require mitered corners, but they're not always exactly 45 degrees. Master mitered corners with tips from an experienced remodeler in this free video on using mitered corners.
Hi, I'm Chris Palmer. Today, I'm going to talk about some applications for mitered corners. There are lots of applications for mitered corners in building. Looking inside your home at the baseboard for example, you'd probably find miters on an inside corner of your walls or on an outside corner. So, an inside corner is when two walls meet in this direction. A miter joint is a really excellent way to make that inner section on your trim. Don't assume that it's going to be exactly 45 degrees especially if you are working in an older home. It could be anywhere one to three degrees on either side of that, that you'll have to adjust those cuts to make it fit tightly. Here is a picture frame that is made up all of 45 degree miters. It to cut, to cut these you lay the board flat on your miter saw as opposed to up on edge with your miter saw. Again don't assume they are all going to be perfect 45s. If you get a little bit of variation in length go...you might have to do some adjusting to get all these corners to come in tight. They, they can be finicky, it's a simple joint but to get them perfect it takes patience. Here is a simple box made with all 45 degree mitered corners. Really all this is are four outside corners that we already talked about. Again when you are building this at home take your time and adjust the miters to where they fit really nice and tight. Use glue on both sides. This is half long grain, half short grain so it will soak up a fair amount of glue. Also before I glued it up I would sand off that little bit of tear off, tear out there. And you can, you could glue this and nail it with brads. Or you could glue it and clamp it till the glue dries and then reinforce it with a spline. Or even just some tape holding it together till the glue dries will keep it together till you can reinforce it with a spline. And then also there's a scarf joint where two long pieces are joined together in a seamless visual way by using a mitered cut. A scarf joint is used when your boards are too short to make a long run and you need to use two boards. Instead of just butting up square corners together, if you cut opposite miters in there it gives you a stronger glue bond as well as a visually much more attractive joint. You would definitely want to use glue on this. Put glue on both sides, on both cuts. Lay it in there perfectly. Nail through the long point and that will catch both pieces of wood and hold it securely. Thanks so much for watching. I'm Chris Palmer. Those are some applications for mitered corners.
