This past weekend I bought an old Bridgeport mill off of Craigslist. The seller was selling all his machinery. He claimed to have not used the mill in over ten years and looking at the ways it looked as if it had not been used in at least a few years.
The mill actually cleaned up better than expected and the motor belt seemed to move with very little resistance.
I wired up a 230v plug to the phase-o-matic static converter that was included with the mill then Boom! my dream came crashing down. White smoke started to come out of the motor while running.
I then changed the stepped pulley from 2700 rpm to 1700 rpm speed ( measured with a tachometer) and same result- white smoke after about 20 seconds of run time.
When it was at speed the motor and spindle actually seemed quieter than what I expected. I did touch the motor head after 20 seconds running it seemed very warm- borderline hot.
My questions are, can this be normal for a motor that has not been run in years? if not normal, any idea how I should proceed? remove motor or j- head and inspect?
Any help is appreciated.
