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
 * 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.
