Mortice and Tenon Test Pieces

These are some more mortices and tenon test pieces. They fit nicely but I think there's enough room for glue.

I now need to make some angle plates so I can machine these at the angles I need for the chairs.
I think you could make the tenons and mortices different shapes if required, which is an interesting option where multiple joints want to be in the same space, such as where two rails attach to the same upright.
