    I know of a 3-phase 220/440 step up transformer for sale cheap, but it is 12KVA and I only need 2KVA, maybe 3KVA at the most. Would it still work ok or would there be huge losses or other problems?

    Over the years I have seen many 220/440 machine transformers dirt cheap, just wish I could find 3 identical ones right now. This is for my home hobby shop, so for me it is definitely worth the...

    3 Phase Transformer

    I have been looking for a used 3KVA 3 phase transformer to step up the output of my rotary phase converter to 440V, no luck so far. Used single phase 220V/440V machine transformers are easier to...

    Did you find your answers about the Fuji VFD? I have had good results with a 5kHz carrier frequency, low noise and I think lower frequency is better in general. I set F37 to "2" for auto torque...

    I would go with the manufacturer’s recommendation. The pot has to be high enough wattage to take the maximum current to the analog input via the wiper. And it has to be low enough resistance to...

    Measuring VFD Input Current

    Evidently you can't use an analog clamp-on ammeter to measure VFD INPUT current, at least the kind I have. I suspect that it has to do with the digital nature of the VFD and the response of the...

    I just bought a Columbian 604 1/2. The jaw faces don't look that bad, but they do clamp on the right side. Right handers tend to use the left side of a vise and wear it there. I would rather have...

    I played with the VFD some more. I guess I am not worried about any noise at this point, I am more concerned about the lack of smoothness. It is not as smooth running as my good VFD, kind of jerky...

    Are cheap VFD's typically noisier?

    I just purchased a new cheap Chinese VFD to try out. I also have a higher quality Japanese VFD. I compared both VFD's running the same 3hp 60hz 1750 rpm motor. The Japanese VFD ran the motor very...

  11. Has anyone actually run a 208V motor on 230v?

    I know that you shouldn't theoretically run a 208V motor on 230V, but I would like to hear from someone who has actually tried it. My 2 applications are not full hp continuous duty and I can put a...

    I have a #4 brake like yours in the photos. Did you ever find a manual? I am missing the linkage parts on the rod that pull down the fingers.

    Serpentine Belt on South Bend Lathe

    I recently put a serpentine belt on my South Bend 13" lathe. It grips much better than the leather and woven belts I tried, and with less belt tension. The problem with splicing a serpentine belt...

    Chris,

    The old leather belt that came off my 13" SB lathe is about 62", so I would say the right size should be a little less than that (61"?). The new serpentine belt I bought is a 745K12, which...
  15. Serpentine Belt for SB Lathe

    I just bought a serpentine belt on e-Bay for my 13" SB lathe. It is 1 5/8" wide with 12 ribs, so I am going to remove one rib to make it about 1 1/2" wide. When I got the belt, I realized that my...

    I think it is interesting that people familiar with these lathes can't tell for sure if it is a 10" or a 13". Looks like a 10" to me, but I am only 80% sure myself.

    13" SB Lathe with Cabinet?

    Has anyone ever seen a 13" SB lathe with a cabinet instead of a cast base and leg? I talked to a guy that says he has one, but I am wondering if it might actually be a smaller lathe. He said it is...
