Homebrew PCBs

Thanks again Alan!

The blue version is around (used). They all have sort of a weird 
shape, but I guess if I do the body mounted standoffs like yours, it 
wouldn't make much difference. A perfect cylinder sure would look cool 
though. :) There's an older Dremel that looks like that, but it could 
sound like a chainsaw.

One complaint I saw on the blue one, was that it doesn't really allow 
for the lower speeds. I've got a varispeed box here that may work, but 
I've heard it can do nasty things to certain types of motors. You may 
have noticed the post here about the lower speeds being adequate most 
of the time. I realize that isn't the best idea for the carbides, but 
if it does OK, it would make a heck of a difference noise-wise. I tend 
to do boards late at night, usually at home. 

I'm still planning to check a newsgroup too. I'm not sure what would 
be the best group for that. It's possible there's someone out there 
who uses them all day and has owned twelve different models. I'm in no 
hurry. The Christmas junk has given me no chance of working on a press 
for at least a few days.

BTW- I do sound crap and I've got a couple dB meters here, as well as 
software that can capture spectrum and FFT shots. If I can get more 
than one roto, I may try that. It would probably give a good idea of 
who makes the more obnoxious sound.
