I'll still do mine..MY way. Maybe you might remember back to about.....1700s or so( when you were but an apprentise..) Maybe they did this by hand tools, too?
I started doing these FINGER JOINTS as a "break" from dovetails.....nothing more. Doesn't take much in the way of tooling, mostly a common backsaw, a mallet and chisel, and something to lay them out with. I usually do this sort of work sitting down on my shop stool. Running 3/16 finger joints right now. Sizes will depend on the chisel I use. Too thin of fingers, makes it look machine made, like a crate. Too fat....more to just show off the joinery. Most of mine have been the same thickness of the wood I was using to make the box. For those that use mainly hand tools, this is a simple way to make them. BTW,shop does NOT have a tablesaw, no room.
