Here is a saw I made. It has a cocobolo handle, slotted copper back, .032” 1095 steel blade, and split nut screws. The saw took a lot of trial and error to get it cutting smooth. I first toothed it at 9 TPI but ran into issues right away. The teeth bit way too hard in anything besides doug fir to be practical, I tried filing the teeth with a bit less rake to them but it is a heavy saw with wide teeth, it wasn’t going to work. I refiled it to 11 TPI with a mild rake angle and it ended up being the right combination for cut speed and smoothness. It still has a bit of grab when starting the cut but it goes smoothly after that.
I’ve got a blog going on how I build these and will be adding more of the steps I take to make the saws. Quick note on the copper spine: it is must slower to mill when compared to brass.
13 3/4” Blade Length
4 5/8” Cut Depth
19” Overall Length
Back 1/4” x 1”
-- Power to the people.
