I've been messing with my power drawbar now for a couple weeks and can't seem to get it to work consistently. Here's my problem, when i get the drawbar tightened to the point where the tool has no pull out during machining, the drawbar releases the tool fine before i machine anything but once i do the littlest amount of machining , the tool then will not release.

I've tried using different pound washers, stacking them in series and parallel, different amount of cylinder stoke to compress springs, i've tried lubricating the drawbar components according to Tormach's website and un-lubricated, different air pressures, not sure what else to try

any ideas? It's a floating plate design on a LMS x2

any help is greatly appreciated
Thanks
