RE: Gas engine starter
A friend of mine used to be the head of the Japanese group on the Byron Aviation show. He had to start a bunch of zeroes fast at the beginning of the show, he had a two handed starter built out of some type of car starter, this thing weighs about 10-15 pounds with the battery on the ground ! ha ha ha
I have never seen it used first hand.
As for using the drill to start motors, I tried this for awhile but the drill seemed to want to spin the chuck loose and kick out the shaft holding the cup.I thought I was really tightening it well, its one of those hand twist types. But the spinning up hard counter clockwise seemed to loosen it?
