Counter-bearing drag

[John Ross]

That is what I should have remembered, your 'hovercraft' drill.

I like the double drill idea, I can see how it would be more controllable.

One guy around here uses a hand drill, and I don't think he double drills. I 
haven't had a chance to tune one after he has done it, so I don't know how 
it works out.
He says he holds the air hose at the same time, for cooling. I don't know 
where he gets the extra arm. :-)

Is that a radial arm drill press?
