I can't edit my post. Addendum With constant load a synchronous motor will not change speed relative to the mains frequency, it will vary a small amount based on load/slip ~50 RPM from no load to full load.

An oscilloscope would not be particularly useful to evaluate this problem. The correct tool for this is a power quality meter/recorder. We designed and sold them in large quantities to PG&E. Power utilities have these and if you complain they might come out and leave one for a week so they can...

Looking for Ali Express type suggestions for a carbide insert tool holder and inserts for chamfering the open end after facing when using a lathe I have been using SDNCN1212H07, however would prefer something with a smaller angle and ideally a holder that projects to the left. Something like...

If it can be done with tubes, it can be done with transistors. Having the knowledge to do it well that's another thing. If I had one, conversion would be at the top of my list.

Well another X for Vevor. I ordered a drill dispenser cabinet, when I ordered it they claimed it would be delivered today. Looks like UPS finally has it in BC as of today and now it will be delivered Friday if I'm lucky. Not a big deal but don't advertise a delivery date and then ship a week...

What a word salad that conveys little information. I prefer the way we implemented it in our products. "All uses settings are automatically saved to nonvolatile memory on power down or power failure" One of a thousand reasons we were able to sell our products for $100k per.

T1 to T8 T4 to T5 to one leg of 240V P1 to thermal cutout to other leg of 240V Ground to ground Test the thermal cutout It was probably clipped for a reason.

My Ditron sums knee and quill. Only complaint is that if I kill the power source, it does not save the coordinates, if I power it off with the switch it does.

The advice I revived here was to look for a good used made in Taiwan smaller knee mill. That was good advice. Found one with tooling and vise for $2500. I'm very happy with it. They do come on Kijiji every 6 months or so, when they do you will need to act because they usually don't last long...

I'm curious are you powering this with 240V? The T5 connection to one side of 240V appears incorrect.
