I have a 60 gallon upright air compressor and it seems to run the

air
drill fine. I've never seen an electric drill that turned RPMs in

the
thousands.


I have an electric drill that runs at 3000, great for drilling 1/8
but not that good for under that size. It's home made, used the motor
out of a B&D lawnmower, it used the same caseing as one of the small
B&D's but with a higher gear ratio.

My Makita cordless at work might do a few HUNDRED RPM. When





I bought my Sioux, it was the highest speed air drill I found at an
aviation tool supply. Oh well, that's life...

I love my Sioux drill. Great trigger. Mine only goes 2600 RPM.

Seems
to do just fine at that speed.

Dear Scott,

I don' t want to bust up your romance but I suggest you borrow a

drill-motor
that turns at a higher speed and shoot a few holes. You really

don't know what
you're missing.

I usta have a B&D 'aviation' drill motor, turned something like

4000 rpm. Wore
it out. Had it rebuilt. Twenty years later it needed another

rebuild but the
bull-gear was not available at a price I could afford. Since

then I've been
using those cheap Chinee imports that turn 3600 rpm, last just

about long
enough for one airplane's-worth of holes, throw it away when it

gets noisy.
Air tools are nice but compressing air to drive a drill puts you

on the wrong
side of the economic equation here in southern California.

That's a point a lot of newbies miss. Pneumatic drill is a real

air hog; takes
a pretty good compresser to keep you working. (On the other

hand, pneumatic
riveting hammers or squeezers don't use much air.) If a guy

doesn't already
have a big compressor, when you add the acquisition cost to the

operating cost
and divide by the number of holes, it represents a significant

increase in cost
when compared to using throw-away electric drill motors.
