The mitre joint is an end-grain joint. Typically this joint by itself is not very strong. Therefore reinforcing the joint would be my approach. I would probably opt for a splined mitre, which is a fairly easy joint to make, but any method of reinforcing the mitre would be, in my opinion, better than not reinforcing.

I ran across an article which suggests that polyurethane glue is a superior glue to PVA yellow wood glue for gluing end grain. However the argument, made by Gorilla Glue founder, is not based formal testing.

thanks folks. Eugd, unfortunately I am going for a full solid wood design, i.e. no plywood, but that video was helpful nonetheless.

i know miter joints aren’t that strong alone, but was hoping someone could say all the fears are overblown re: the strength of the joint. looks like i’ll probably have to reinforce them somehow. I’m also going to use 2 part epoxy to glue the joints, allowing the edges one coat of epoxy to sit for 10-15 min or so before re-applying some more and putting the two edges together – this should mitigate the glue up the straw/grain issue somewhat. i’ll also probably go with some angle iron plates along each joint to support the miters and will likely use dowels as well to reinforce them from within the joint itself.

will plain miter joints be too weak?

Yup, they will be too weak. You’re going to spend a lot of money on wood and invest a lot of time. How are you going to feel when it falls apart? Use better joinery than miter. Full blind dovetails will look like a miter joint but will have the strength of dovetails, if that is the look you must have.

I know it was a idea how you could get the corners you were looking with a little strength, if you make the box inside out of plywood and paint or do a clear coat you will get some contrast and add a little stability then wrap it with solid wood to get the mitered corners you want.

Have your say...
