How to get nice corners on a plywood box.

Page 2 of 2  

I just found this site. This is exactly what I am trying to achieve. But without the internal snare stuff...

Here's our first attempt http://www.anneldavis.com/bobandanne/cajon.htm .
The corners were mitered with biscuits, then hand planed at a 45 degree angle to ease each corner, after staining.
1/4" is too thick for the drum "skin". Use 1/8" baltic birch. We used all baltic birch, 1/2" sides, 1/8" drum skin and 1/4" back.
The cajon we built has an awesome sound. We paid a lot of attention to making the joints air tight.

Bob,
Awesome!!! That is exactly what I'm looking for. Would you be so kind as to post dimensions? HxWxL and the radius of the sound hole? Is there anyway that you know of to cut holes for biscuits without a biscuit jointer? With both of the boys in college I am on a very tight budget. Also, I noticed you glued the front skin on, in some examples I have seen screws used, do you know why this is? They always seem to be in certain pattern with more at the bottom then the top. When you glued the skin and soundboard on did you have them flush with the edges and then 45 them? In other words, was the OD of both of them the same as the OD of the box?
Thanks a lot,
Jim

the current fine working has an article you might find interesting. The author is making a carcase, but wanted mitered corners. He cut a dado in each miter, layed the pieces together flat on the bench, outside up and used packing tape to hold them together. Then flipped the assembly and spread glue on each side. the tape acts as a clamp as the box is 'rolled' up. Finally, and while the glue is wet, he inserted splines into the dadoes to square eveything up.
Looked simpler than I am making it sound, though.
