What torque is your arm rated for? It seems unlikely that any human can
put a 1000# push on a handheld tool that might be 12" in diameter at
most.

The mass of the wrench absorbs the "instantanious torque" or "impact".
Mean torque, or average torque, may be as little as 100-150 ft lbs and
still have a 1000 ft lb rating - without stretching things at all (or
very little)


The other day it would not remove the bolts that hold on my
front brake caliper bracket and sometimes it wll not remove lugnuts. I
am using it at 125psi with 50' of 3/8" hose and 1/4" M (milton) quick
connects). Would going to 3/8" qc fittings help at all? I notived a
local tire shop has the air pressure at 150 psi. Is this what is
needed? How come air tools say never to go above 90 psi?
