Pretty simple and easy too. I found this chunk of maple late on Sunday afternoon, and had a finished tool by the time the sun went down.
I didn’t set out with the plan of getting all fancy with the wedge, but I got bored while the glue was drying on the other part. The shape kind of reminds me of a shaving curl, which makes me like it a lot.
If you want to build your own, mine was done just like this tutorial
Really, the only main difference is that I sketched out a different design that appealed to me. Also I didn’t mess with carving out the spot for the chisel. Instead I split the board lengthwise, sawed out each half, and then glued back together. (It’s arguably simpler/faster/easier that way, but whichever way you want to skin that cat.)
Hope this inspires somebody. If so, post pics of your build! :)
If you don't "know enough"... try anyway! (Cuz that's how you learn.)
