Another use for which I find isoproply alcohol to be invaluable is
as a lubricant when drilling through aluminum. It makes the bit
cut cleanly and bite like it's going thru warm butter!!! Signif-
icantly better/cleaner/faster than when using most other commonly-
used drilling lubricants. The difference is pretty astounding.
I mention this because I'm sure many of us have cursed at the length
of time it sometimes takes when we're drilling thru thick aluminum
plates for boom-to-mast plates, etc.
I wish I could claim originality for this hint, but I got it from
an old QST, probably 25 or so years ago.
Who'da thunk it?
