185psi air, that is high!!! But not high enough.
A 1" diameter cylinder will give you about 145 pounds of force closing your air vise, not enough I am afraid. You would need something like a 3" or 4" diameter cylinder.
If you do not have a vise make yourself some halfmoon clamps that are closed using a couple of bolts, just like a split clamp except one half is machined into your plate.
