sorry. I didn't think to get a photo while at school. Interesting how frustration hinders thinking.

Check your math on that one, don't trust someone else with it every time.
apologies - I mis-typed. 0.307 is the Rod diameter. the effective area is the piston area minus that,
3.14 sq in - 0.307 sq in = 2.8 sq in.

2.8 sq in * 60 p/sq in = 170 pounds

(I will update my previous post to correct this)

I wonder if this is as stupid as having a bad pressure gauge. It says 60 psi, but this is from the old parts bin and we have had similar disappointments in "Actual Force" on our pneumatics before. Maybe we have a bad gauge lurking. I think that would be a good thing to check, just in case.
