    Congratulations, they're nice machines. There are only maybe 3 or 4 lathes in this work envelope I'd trade mine for (and RC has one of them). While I don't like the Kopp variators, if yours works properly, think 3 times before swapping it out. You are *not* going to get the equivalent speed range from a motor with VFD by just varying the motor frequency. Using a VFD to get 3 phase assuming the motor can be set to use 220V is a different matter of course. I'd suggest changing the oil in the variator anyway. Make sure it's the right sort and filled to the correct level. Seems a lot of problems with the variators are due to wrong type or amount of oil. PDW

    Thanks.
    going VFD is purely for 3 phase as I don't have to phase installed so that is the only way i can get this running in the cheap .
    i will go over it , clean up and oil all area where it needed before run it .

    Well done. These seem to be excellent lathes. I was only looking at one 30 mins ago. It is sitting on the back of my truck along with a Nuttall lathe, Pal mill and Arbroga drill. Unfortunately it is not mine. I picked the machines up for a friend who inherited them from his uncle. Luckily though he didn't want the Arbroga ER 825 drill and the Power surface grinder ( which I am still to pick up) so you can guess were they are staying!
    Will probably have to help set up the Chipmaster when I delivery it so hopefully will get a chance to have a play then.

    Very nice indeed!

    My inlaws have a Colchester bantam in their shed. They are beautiful machines. It never gets used!

    Girl, I don't wanna know about your mild-mannered alter ego or anything like that." I mean, you tell me you're, uh, super-mega-ultra-lightning babe? That's all right with me. I'm good. I'm good.

    Hi Stuart .
    sorry I send the wrong link. he have the 240v~415v on his other auction. it just that at the moment he only have the 1.5kw unit. but i'm sure if i ask him for the 4kw one he should have it as well.
    check his other auction
    cheers

    1 5KW VSD VFD Inverter Single Phase 240V TO 3 Phase 415V Variable Speed Drive | eBay

    Well thats more like it.

    Way cheaper than Drives Direct by the look of it(though it was a quick look). I had heard of Chinese 240 to 415V VSDs... from Joe maybe? but I'd not seen one for sale before now.

    Yes, but how are you going to get 4kW out of the VFD if you can only put 2.2kW (10A plug) or 3.3 kW (15A plug) into it - and that is not taking into account losses within the VFD. If the Variator works you are better off putting the biggest single phase motor you can drive. While you can use a 4kW VFD you can't get more out of them than you put in and last time I looked (many years ago) the conversion efficiency was something like 80%, so if you are feeding 3.3kW in, you are likely to only see a bit over 2 1/2kW out.
