A 2 hour endeavor. Ground off the closed end, cut 2 pieces of mahogany, used straight bit on router table and cut tight channel approx 2 in deep for wrench shaft, glued together with Gorilla Glue, inserted shaft with same glue, used a 50 grit tiny drum on my electric drill held in my vise to fashion a shape, sanded and oiled. Thought of making a mold to pour plastic and form the handle and insert the shaft without glue but , I chose the short cut method. A simple prototype. I certainly would like to see yours once you receive the JessEm table, that is one nice tool
