If you can do with a little AC motor i have one from a Clarke bench drill that got knocked off the bench and shattered the head, i removed the motor and switch and binned the rest of it. Will look at the plate to see what it is tomorrow.

well the news is in from Arc Euro Trade. My motor, and control board have been tested independently on a machine under working conditions.

The board is past being salvaged. The fet I fitted is gone, the board is damaged (no doubt by me) the potentiometer shows signs of fault. On/off switch not tested alone, its not worth bothering with, when used with a  perfect motor after a few minutes was getting hot!

The motor ran ok at low speed, higher speeds emitted a lot of sparks, showed signs of the misfire I reported, became very noisy, they said if used at lower speeds might be ok, but lacked any torque, so its on its last legs. Which failed first, did one component take out the other, what about the fool who stuffed ac into the motor, well that is all in the past now, so decision time.

Its £200 to replace the two parts, plus its not worth sticking with the original pot and on/off switch. new machine is £399, ok not with the belt drive, longer table I have, but brand new.

I said all along I would not spend £200, but now I am in the corner I wasn't really deep down expecting, and I have the nominal fee to pay for the tests. I could buy second hand, but if coming from an unknown source such as ebay I could be back to all this in  a short space of time. Maybe they machine is an expensive luxury, I only use it occasionally, and then its just some dabbling with model planes and boats, but its real nice to have, and I have a load of tooling now!
I could raise some cash, the machine sold as spares etc should raise £100 (one on ebay now without my upgrades is at £90), I also have a couple of model boats in the attic that could sell as I will probably never finish them.

Is it worth spending £200 on a machine a few years old, or call it a day and move on!

Maybe a quick Wanted on freecycle for an old treadmill? will have motor and controller for free if you are lucky? or a quick scourer on gumtree for something cheap to be a donor?

steampunkpete:
If you can find a cheap / free motor somewhere, then finding a motor of about the right size, speed and power is the starting point. A cheap controller to suit will be found on ebay.
