[Shop-talk] Impact seems...weak

[Jim Juhas]

I agree on the advantages of the battery powered impact tools. I used to 
depend on a generator and a small compressor for wheel and tire work at 
the race track, but now exclusively use the battery ones for that 
purpose. I use them also in the shop most times, but I have a some air 
powered ones that have more capacity that I rely on for the stubborn 
fasteners.

Because of the proliferation of the battery units, I have found deeply 
discounted air units at swap meets, some showing little wear and in 
perfect operating condition. $10 to $20 range; that's why I have 4 of 
them now.
