always put the least skilled (aka "idiot") on the gun, and not the bucking bar end.
No offense intended here, just the same way I've always explained to anyone how to drive rivets. The person with the skill and attention to detail goes on the bucking bar.
Also forgot to mention, a good tight space, 90 degree air drill. I have an old beat up Dotco that a friend of mine, who has a friend who works at Boeing, Seattle, got that friend to pick up a 90 and a 45 drill at the Boeing Employee surplus store. They look like they have been thru the war, but work great.
And the threaded bits to go with the 90 drill.
