Motivation

We are getting some weird movement in the stage right now and so to try and minimize this I will machine the part below to make one solid movable stage.

Current Plan


Stats:

  • Length - 11 inches
  • length from left end to wide part - 6 inches
  • length of wide part - 5 inches SJK 02:57, 1 October 2009 (EDT)

    Wait...are we still talking about the diving board design?
  • diameter of big hole - 2 inches
  • center of hole - 2.5 inches from right side, 1.5in from top/bottom
  • width - narrow part is 1.25in, wide part is 3in
  • depth - .25in
  • left holes - .4375in from left
  • right holes - .875 from left holes
  • 4 left holes are designed for #8 screw (#15 drill for clearance, 5/16 diameter with .164in depth for counterbore)

Comments and Improvements

The screw holes will be counterbored. The big hole can also be counterbored too. That might give the objective a little extra room to work.

Andy Maloney 23:59, 30 September 2009 (EDT): I'm not sure but won't this vibrate? Also, should it be made from stainless steel?

Steve Koch 02:59, 1 October 2009 (EDT): I do think we want to worry about vibrations. Minimizing length is good. I used a diving board in the past so that's at least a bench mark. Friction seems to be killing us now, and I don't have something successful to say that we'll win with the current design. More thinking is good. I don't think that stainless would be better than aluminum. At some point we have to worry about the weight on the piezo and it's response time.
