Just a little fixture for my face plate to allow holding parts that may be odd shaped. The face plate is cast iron from Little Machine Shop. Holes were drilled and tapped in the face plate for this jig. There are 3 sets of "jaws" shown, one for large diameter, one for small, and one blank for whatever. Works with round also but then so does a 4 jaw chuck. Made from hot rolled steel plate and one slice from some hot rolled angle iron. This was really just a test of my "surface grinder" but I wanted to make something usefull that I could use when I get around to making my steam engine.
