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.
