Most of the drilling and cutting is quite straightforward. The three 3⁄4in. (19m.m.) diameter cut outs are made using a chas-sis punch. When the two 3⁄4in. diameter holes in the chassis have been made the positions of the two smaller holes for the coilholders are located using the coilholders themselves as templates.
