TR6 frame - drainage holes, GT6 left hand stalls

["Chris Kent Kantarjiev" <cak@parc.xerox.com>]

The right tool is a hole saw of some variety. For thick metal like a
frame, I'd reach into my metal removing tools drawer for the
"Rotabroach" kit - looks something like a normal hole saw, except that
the cutting surface is about 1/8" across, instead of just 18 gauge (bi-) metal.

Drilling with a drill bit will work, but will leave chips in the frame
(and won't make a round hole).
