Imagine assembling your engine like this, in your garage

I agree,especially with a 3/4 impact, i call mine the howitzer. I dont need it often, but it chokes on my 3/8 air line. Have to wait for pressure to build up.

My 3/4 has to run on a 1/2" line or it has no power, as far as the AMG all the bolts he is tightening up are 6mm or 8mm
