But you would end up making a real one out of mundane matter. Such a real sawtooth would only ever touch on two of the ramp faces, and all the ramps would be at slightly different heights. Rather than a taper gib you could make a setscrew version, as used on many cross-slides, and all over the place on my milling machine. The milling macahine has quite a variety of versions. The Y has L-shaped blocks with screws through from underneath with locknuts. Those bear on a slider-bar with dimples for the screw tips. The Knee slid only has access from the front side, so there are cap-screws to pull the keeper blocks in, and concentric tubes with an external thread to push them back. It's actually slightly more complicated still, with extra anti-rotation parts. But it seems to work well. And then the X is even stranger, as the screws and locknuts are at right-angles to the clamping direction, and apparently use a system of taper wedges. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
