Burnt up my bandsaw today.
I've got a 1945 Wells 8M vertical bandsaw which I resurrected from a barn a few years ago.
These past several weeks I've been rebuilding a 5ton Atlas arbor press.
The press was rusted tight with multiple parts missing. The ram had been cut off with a torch.
Milled a new ram... etc. (I'll post when the press is complete)
Picked up a #400 pound piece of 11inch diameter hot rolled to make a platen and a turn a hand wheel.
The 11inch fits on the horizontal band saw just fine.
Got a third of the way through when the motor started smokin!
6hours and $25 dollars later I've a new/used 3phase motor installed.
I lost nearly a day to the repair, but could have lost my shop.
First thought was must of been a bad or tired 1hp 3ph motor, what ever that means.
However, I believe it is more likely that I was working her to hard despite the slow speed and sharp blade.
I remember the many threads here about shop safety and proper thermal protection etc.
Fortunately I was able to extinguish her by simply turning the saw off.
Had I walked away from the running saw (this will take hours to cut with a slow speed and a sharp blade) my shop might have been filled with flames instead of smoke.
I'm gonna have to step up my understanding of wiring, and thermal protection on all my machines.
I hope you electrical gurus don't mind when I start asking pesky questions.
