a cool cam deg wheel i found on hotrodders forum, designed in auto cad.
just save the picture, and when you print just print to fit on screen.
heres the one i made, i just plasma cutted mine out of 16gauge steel, took about 20 mins or so. or you can use a angle grinder with a cutoff wheel.
glue your deg wheel on it ,then center punch on the x in center of the degree wheel and drill to whatever size you want
