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.
Ok probably not what the inventors of hockey had in mind but it works well. Info on how to make some.
(I am sure this could be done w/o a lathe. The instructions below show the use of a Rockwell lathe but you could probably use a drill press with a wood paddle bit and a drill. )
Here are some photos of the "before" of my Hardinge HCNC Lathe that will eventually be rebuilt and retrofitted. I have had the machine for probably 5 years now and could really use it in the shop. So as time permits I will finally start working on it. It needs a lot of work but the base machine (ways, ball screws, spindle) seem to be in good shape. Back in the day these machine were incredible and many are still in service. The basic motion retrofit is not a big deal for me. The tool changer however is another story. I am missing many of the parts so I am planning on redesigning it to work with parts I can make. Right now I am in the information gathering phase. There are some great examples of retrofits of similar machines such as http://www.wallacecompany.com/cnc_lathe/HNC/. On some levels this project will be more involved because of the missing parts but I am thankful to have some examples to look to. Hopefully this blog will give someone else information they can use to save another one of these beauties.
