So here is my second plane. This one has a brass sole! With the wider infill you only need to machine one side of the brass plate. I added a 'ski jump' to the wedge using curves and boundary surfaces in the CAD program. Unfortuneatly the shaving travel straight up after passing through the mouth. For fun, I'm thinking of developing a rotating wedge on a 1/8th pin above the mouth that will allow you to direct the shaving to the left or right for situations where you are using the plane on its side. Included are photos of the plane going together. The 1/8th diameter brass pins are .540" long so I have a .020" shim with holes for the pins under the plane on the steel block so they projects enough for peening on both sides. It works great. My aim with the ball pien hammer is improving too! The infill is claro walnut and the wedge cocobolo. I picked up a board of East Indian rosewood on the weekend that I plan to use in the next plane. A local blacksmith will cut and temper A2 steel blades for me.
This plane weighs around 2 pounds and works great on face and end grain.
