Close Quarters Impact Wrench

I was in a tight spot under the hood. Not enough torque on the wrench. Not enough room for a cheater bar, or pneumatic impact wrench. Not even enough room to swing a hammer.

The solution?  String a bicycle chain through the closed end of a combo wrench, and through a barbell weight, lock it with vice grips, and hammer away  with the weight pulling the chain. It works.
