Finally finished my adjustable-mouth wood bodied jack plane after about 2 years off and on messing with it. Maple body, jatoba sides/sole, moradillo (pau ferro) tote, purpleheart and mahogany knob. I made the blade from A2 steel flat stock and did the heat treatment in a digital kiln. Finished with Tried & True Varnish Oil.
I don’t really like the color of the knob, I might have to remake it in moradillo.
So far it seems to work great. The wood crosspin has much more friction than the brass rods I tried previously, so it doesn’t take much force to keep the wedge in.
