Two Spurlock jigs, one a mirror image of the other for each side of the hammer, now the problem becomes how to clamp the hammer down effectively.  I have a prototype in the works but it is not there yet.  With a mounted hammer the only way to control weight is to take equal amounts off each side to keep the shank centered.
