On the DC side, I scored a high torque motor - 4 brushes at 90 degrees -
that is 24V. Came out of a small elderly scooter. Some of these are beginning

I might have some Omniturn 90vt DC servo motors. Encoders are likely
dead, but will run fine. Bout 3" in diameter, about 8" long with a 1/2"
shaft about 2" long.

Free but for the shipping if I can find em.

They are about 1/2 hp IRC.

Start looking at Craigslist or Freecycle for a treadmill. Most of

Look under Free and be patient.

Or look in Ebay for a small VFD and then locally for a small 3 phase
motor. I just got a 56 frame three phase motor for $5 at a garage
sale.

I have been looking for a while at garage sales and local auction. I will
expand to Craigs list (where I follow other things). I saw one tread mill
motor at the auction here but it was about twice the size of the Taig
(2.5HP). I am told scroll saws are another possible source. Typically their
motors are rated for about 160 watts but that should do for the Taig (if Don
runs his off a 75W one).


"Lenin called them "useful idiots," those people living in
liberal democracies who by giving moral and material support
to a totalitarian ideology in effect were braiding the rope that
would hang them. Why people who enjoyed freedom and prosperity worked
passionately to destroy both is a fascinating question, one still with us
today. Now the useful idiots can be found in the chorus of appeasement,
reflexive anti-Americanism, and sentimental idealism trying to inhibit
the necessary responses to another freedom-hating ideology, radical Islam"
