Yet another Denford for the collection (Triac Retrofit thread)

I've also got a noisy bearing in the spindle. So il be referring to your other post re this. Do you by any chance have the bearing numbers required?
And roughly how warm does the main casting on yours get when running? Mines pretty hot after a few minutes at 3000 rpm. - presumably the worn bearing :-(

is that 7208ba ? angular contact bearing
are both bearings the same?- i presume there is just 2? - to be honest- not researched it properly yet

Correct two, I'll post a load of photos at some point over the weekend from when I did the bearings

Anyone that is running on single phase
What did you do re coolant pump?
Swap motor? Capacitor a phase to run single phase? Or install a vfd?

My Triac was a single phase machine, so the coolant pump wasn't an issue.

A new pump would probably be the most reliable long term option though.
