Hi Charles,

Thanks for the info....in many ways the Electronic Goldmine; along with all
their potentially
useful electronic items; seems to be potentially one of the best; if not the
only possible source of such mirror
finishes.  They do have a $10.00 minimum; not counting the freight charge.

I checked the other 3-4 major electronic surplus's on the web...none have
carbide drills/router bits that I noted.

The useful router shank bits appear to be roughly ~1.25"; which is more than
enough length.  The cutting ends can
usually be easily knocked off in a vise.

They also appear to have acouple small di-sectible and relatively cheap
120AC relays...from which one "might" try to
salvage the coil for a seismo.  Alot of these relays are tough to retrieve
the coil intact; without damage.

Hmmm, the guy that owes/runs it used to be in Denver and was running a
surplus many years back; but his name escapes
me now.  I know because he told me he was moving to Arizona before he left.
Real nice guy.  Of course it could be
someone else running it now.

Take care, Meredith

Hi Charles, 

Thanks for the info....in many ways the Electronic Goldmine; along with all their potentially
useful electronic items; seems to be potentially one of the best; if not the only possible source of such mirror

finishes.  They do have a $10.00 minimum; not counting the freight charge.

I checked the other 3-4 major electronic surplus's on the web...none have carbide drills/router bits that I noted.

The useful router shank bits appear to be roughly ~1.25"; which is more than enough length.  The cutting ends can

usually be easily knocked off in a vise.

They also appear to have acouple small di-sectible and relatively cheap 120AC relays...from which one "might" try to
salvage the coil for a seismo.  Alot of these relays are tough to retrieve the coil intact; without damage.

They have individual carbide drill and router bits at $0.99 apiece. They also pretty much always have a grab bag of bits.  I just checked and item no. G13259 is a bag of 8 or so bits for $2 -- a great deal. I've bought these over the years from Goldmine to use in my Dremel tool. They're a great bargain.  When the Dremel HS steel burrs and router are used on steel, they dull instantly, whereas the carbide bits keep on taking away metal.  They're the only bits I use.  I tend to break them faster than I wear them out.  With regards to seismo pivots, the shanks are a consistent 1/8" size for everything and the router bit were mirror polished in the last batch I bought maybe six months ago  so you might not even have to polish them.  So far as I can figure they're very good, micro-grain carbide bits that come out of the circuit board industry.




Anyway, just another thought.

Charles Patton
