A torque multiplier...I learn something new every day. A bit expensive though.
I just noticed this old auction
HERE. If you think about the way it works, it's really a great idea. I don't know how it actually performs in the real world, but the concept is awesome.
On to impact guns...
Considering the torque multiplier effect and knowing they could have geared that 24v impact gun anyway they wanted, I'm really interested in hearing from anyone that's used one on rusted-stuck budd nuts. I've used a 1,200 Ft-lb Ingersol Rand impact gun with the correct diameter air hose and over-pressure from the compressor, yet that's only *barely* loosened the nuts...after going forward/reverse a half dozen times and using heat. I can't believe a 24v gun just plugs in and spins them off with ease. But I am prepared to be convinced....
