Home Made Crimper

These are the $21 hex crimpers that I have been using to crimp the connections on my Wabbit. I bought a $20 set of bolt cutters at the flea market as well as a $1, 13mm six-point socket. I sliced the socket almost in two with a saw. I then carved out a hole in the jaws af the bolt cutters with a grinder. Next, I welded in the 13mm socket. then, I sawed away the non-hex part of the socket, then trimmed and smoothed what remained.

The crimped battery jumper shown was made with these crimpers. Two overlapping crimps were made. Each stroke of the crimper makes a crimp about 1/2 inch wide. The barrel of the lug grows in length about 1/4 inch during the crimping process.
