I cut down a friends almost dead apple tree yesterday. I wanted to split some of it to see if it will dry better. So I made a couple riving froes today. Just some steel bar stock welded to pipe nipples. Turned the big handle and used another handle I had. Heated to cherry in the wood stove and oil hardened the blades. FYI oil harden outside, I knew it was going to flame up but wow what a stench in the shop. Maybe after it dries I’ll have some useable apple wood for tool handles.
