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. 
<![CDATA[Hockey Puck Leveling Feet]]>Thu, 19 Apr 2012 01:20:17 GMThttp://conesusmachinetool.com/cmt-blog/hockey-puck-leveling-feetOk probably not what the inventors of hockey had in mind but it works well. Info on how to make some.


  • (1) per- hockey puck
  • (1) per- 5/8"-11 4" long FULLY threaded bolt. Carriage bolts would work also. 
  • (3) per- hex nut
  • (1) per- 5/8" washer

(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. )
  • Chuck up the puck.
  • Use a 5/8" drill and drill hole in middle of puck.
  • Use boring bar and place a .25 deep 1" dia pocket on center as shown. This is probably the only semi critical part of the entire part. You want to make sure the pocket is deep enough so the bolt head sits below the bottom surface of the leveling foot. 
  • Assemble... yep very easy.

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.
