"hydraulic" artist bench problems

[Farrell]

55 lbs. from a bicycle pump is the same as 55 lbs. from an air compressor 
(I'm assuming lbs.= psi). Just as you would want to be sure the bicycle pump 
has a gauge on it to monitor air pressure, make sure the compressor has a 
pressure limiting valve such that the intended maximum pressure is pre-set.

Come to think of it, it's time to pump up my bicycle tires for my Saturday 
morning ride!  (With a compressor!)
