Pneumatic presses was RE: Emailing: P2130064

[Jude Reveley/Absolute Piano]

Nice job David! 

I just had to retool for my RC&S project (my 2nd pneumatic press in as many years, ouch). I did go with the perforated strut which I love, but the aluminum cross bars seem like they might be nice and light. I also added a torsion spring so the top bar could just hang out during set-up and disassembly.

Back to work...all the best,

  Sorry, forgot to rename my photo emailer with the original message.  



  I toyed with the idea of a screw press but since there are different length ribs, where to locate the screws, just how many screws to put in each one, how to make them mobile etc., how do distribute the pressure evenly and thoroughly all convinced me that pneumatic was better.  My set consists of 6 presses of varying lengths: 1 at 5', 2 at 3', 3 at 4'.  In retrospect, I should have built another 5 footer.  Also, I may end up switching the angle aluminum to perforated angle struts which would have been cheaper and easier with more options for placement of the pins for holding down the upper beam.
