Pulling wires...

I strapped a big ole 1/2 elec drill to a chunk of 2x12 to stand on. Put a 1/2 nut and bolt thru a 2 inch+ fan spacer, or a suitable small pulley, and wrap the tether around the spacer/pulley/capstan, let the drill pull the wire.

Takes a bit of practice, saves a lotta tuggin,, use lotsa lube..

cheers
