We are in the heart of pecan country in Arizona in the winter and there is a lot pecan cracking going on. I have been thinking abut a different type of “splitter” and finally got around to trying a design. I don’t have any drawings, I just started making parts out of scraps of wood laying around the shop until it came together.
The base is sycamore, the center block is Jarrah and the arm and upright are white oak.
Instead of just crushing the shell from both ends, I have 4 utility knife blades around a spring loaded plunger on the bottom to slit the shell. They are held in with set screws. The Jarrah wood taps very nicely and makes good threaded holes for the set screws. I started with just a hole in the wood arm at the top but then added the brass sleeve with a 30 degree taper on the inside to center the nut. I have one more change to put knife edge on the end of the screw holding in the top brass insert. I want to get some splitting action up there as well. The bandsaw blade cut was just the right width for the utility knife blades!!
It takes a feel to get it to split just right and not crush the pecan to pieces but I did manage to get many of the nut meats out in one piece.
I finished it with clear lacquer.
