[AT] 1/2" air wrench

[charlie hill]

John get one with plenty of torque.  800 ft lbs is not too much for some big 
bolts.   For example the head bolts on some Cummins diesel engines torque to 
about that much.
When you get a job for it that you are afraid you might overdo you can dial 
the air pressure regulator back on the supply line and cut back on what the 
wrench  is doing.

Subject: [AT] 1/2" air wrench

Unless I can get a rebuild kit, I'm going to have to replace our 1/2" air 
wrench. Been looking at the specs on some that are almost scary. 800lbs of 
torque is enough to break a lot of stubborn bolts. The wrench we have now 
has 3 settings for tightening but only 1 for backing bolts out. What's your 
thoughts on how much torque is too much? Anybody got a particular wrench 
they recommend?
