I have 16- 45 degree mortises to chop in the frame and the stretcher for this table. I made this guide block and the photo below shows the half assembled block with the two angled guides that I will chisel to. The small block with the holes in it are a drill guide that I will use to drill out waste before chiseling. That guide will be slipped into the block loosely and after drilling it can be pulled out for chisel work. I am hoping that the drill guide holds up but I have a buddy who said we could make it out of aluminum if need be.
The next photo shows the guide and drill bit in place in the assembled block. When actually drilling I will put a C-Clamp across the entire jig.
This photo shows the position of the chisel when chiseling to the guide block.
Next I will start layout on the blanks and start drilling and chopping.
