Ernest,
I have an air compressor that you can borrow if you like.  It will probably
do a pretty good job with an air grinder.

Regards,
Steve Brooks

You've discovered the reason you can buy them for $15. :-)  I buy a lot
of stuff from Harbor Freight (a lot like NT), but I haven't had much
luck with their power tools.

I've tried to get familiar with where all the 'well stocked' pawn shops
are located in the areas where I typically drive. If I have time, I stop
in & look over their tool selections periodically.  Around here, I'll
see the putrid green $25 B&D homeowner grade drills priced at $35 &
right beside them, B&D 'HolGun' series (~$175 retail) for ...$35. Same
story for industrial grade Skill & Milwaukee tools. The only way you'll
wear out one of these industrial grade drills is to pour grinding
compound into the bearings.

For one-time work like you're doing, HF sells an electric tool with a
1/4" collet for about $20 when it's on sale. It's intended to be a
laminate trimmer, but you can remove the 'foot' & it will function like
a high speed air grinder.

Now, how do I get my freshly installed Puppy Linux computer to
automatically recognize shared folders on my Windoze computer attached
to the same network?
