This post is related to the air closer post. Now that the air closer project is started I realized that I need to figure out how much air pressure to use. I could do this empirically but this approach may show that my air closer isn't up to the job. After I have gone through the the whole process of adapting it to the lathe in question. The max air pressure I can use is 150 PSI which is dictated by the rotary union. So, how would I measure the clamping pressure the collet puts on the part? In production the part is clamped in the collet .050 from the collet face. The dead length stop controls this distance. But I think I can remove the stop and grip on something that is about .500 long and still get a good idea of the clamping capabilities of my air closer. I have the gauges but I'm not sure what would be best to squeeze on. Thanks, Eric
