My Kearney & Trecker Model H Dividing Head has the option to use special "high number" plates to give users more options for divisions that can be made by having a set of three plates with higher number of holes than their regular plates. In order to use these high number plates, you need a special pin that fits into the smaller holes in these plates. Not having that particular pin for my dividing head, I decided to make one by turning it on the metal lathe and then heat treating it to get it to the proper hardness and then grinding it to the final precision size on the surface grinder using a spin fixture.
