Well I got the box almost finished over the weekend. I am going to use
keys, I just had the terminology wrong. I'm inserting 2 to a corner,
1/8". I used my mitre saw and it is very tight. I also did "the flip"
so that the grain matches all the way 'round. I did a 1/4x3/4 rabbit
around the top for the cocobolo piece to sit in for a top, then I cut a
half circle so that you can grab it and lift it out. The glue should
be set tonight and I will cut the slots for the keys and then put a
finish in it. I'm thinking of trying ferrous sulfate...
