Building a bed for my 6-month-old, who will soon have outgrown his crib.

I'm thinking of trying to use "fox tenon" joints, whereby a couple of slots
are cut in the tenon, small wedges are placed in the slots, and as the tenon
is driven into the mortise, the tenon expands, giving a very tight fit
indeed.

As I understand it, if you make the wedges too long, the tenon shoulders
won't reach the piece with the mortise, and you'll never get the thing out.
You only get one chance to get it right.

I've never done anything like this before. Any tips? I'm intending to use
beech, if it makes any difference.

Build one that is half of the finished size, just like someone took a
finished joint and cut it in half for a picture. since this one will have
an open face, instead of being boxed in, you cah gently pry the tenoned
piece out of the moriced piece.
Youmight als obe able toleave the whole depth of the mortice and just cut
off the face part, to get the full seating width of the mortice. Use a
piece of plexiglass as a cover while seating the tenon.
Also, drill a small hole wat the inner end of the split, it's supposed to
help prevent splitting.
