What pressure do you run on your air compressor for a air/hydraulic setup to bend 1.5 inch tube with .120 wall? I just got my setup running and it stalled on my 2nd bend when the 14" ram is out about 7". first bend went well after spending a lot of time bleeding it today. I am at 110psi. I think I may need to bleed the system better but wanted to see what people think about the pressure first.
