We had no good way to easily hold larger work on our Sherline Mini Mill at FLCC. So we made a clamping system and we cut our first parts with it today.  The students manually wrote a CNC program to drill all the holes. We made one adjustable back jaw that can be moved to any hole position on the plate. We also made Mitee-Bite style cam action clamps on the other side.  We can now use this plate to machine larger molds for the injection molding machine and sand casting patterns.  I will share the plans when I get a chance.
