Looks really great David. How much bend do you get from the aluminum beams? Gosh, those must be light! My 5' press gets pretty heavy. Because I use a radiused upper caul, plus the difference among rib heights, I find that I need to position the upper caul up or down several millimeters for any given rib. In the picture below you can see my upper retaining pin at the top of my angle iron. That is located in one fixed position. I simply have an assortment of maple spacer blocks that I place between the retaining pin and the top of the upper caul so that I get the hose shape I want (not squished and hanging over the sides of the rib, and not so high that the hose isn't in full contact with the rib). (Sorry the picture is kinda dark - couldn't find another better one.) 'Course, I guess you'd "have" to make yours out of aluminum - or maybe titanium! Or not. Terry Farrell ----- 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.
