    From the picture of the upper guide, it looks to me like you just need two new bearings to complete the guide assembly. What about on the lower end?

    ...Built-in blade welder and all.

    Good luck. If everything's there and nothing's broken, you should be in business in no time.

The Laidlaw may be a different story, since it has a gear box driven by a flat belt from the motor, but I haven't yet tried it on the 3HP converter. I don't know if you will have any luck at all with a static converter. It really depends on how the drive is on the saw and how much grunt you're looking at to get her moving.
    I thought my posts were invisible to you, but I'll try again.

    I would hedge a bet that you need at least a 3HP 3PH rotary converter.
    I'm not an electrician, though. This is based on my experience as I mentioned above.

    How many wires are coming out of the motor?

    Did you get bearings for the upper and lower guides yet?
    Do the wheels spin true?
    How is the drive-train?
    I would work backwards from there. You can always swap in a single-phase motor if you don't have other three-phase equipment.

    Yes I saw your posts Chris thanx,,,,,,I wasn't exactly sure if I was reading the numbers on the motor right or not........I'm used to Apparently American made motors where 1 phase and 3 phase are clearly stated. I didn't really get that from looking at the tag on the motor on my saw.......I definitely am looking at using a rotary convertor if the motor is good,I can buy a cheaper mill/lathe and other stuff if I get the rotary convertor. As of right now the wheels seem to spin true..I'm cleaning up alot of surface rust on the table the speed adjustment looks similar to a centrifugal clutch ,,gearbox seems as though it works ..seems to be free and moving I haven't messed with the guide bearing yet I'm going to pull the table off and mess with all that in the near future. Did you see the pic of the motor tag Chris??I just want to make sure where I'm going with it .......when I'm not sure I get real ANTSY about moving forward......Any way Thanx Again for the info Jim

    Hi Jim,

    I saw the tag, but wasn't clear on single or three phase either.
    I did check out the motor manufacturer's website, though, and everything was three phase.
    Also, most machinery of that size and application tends to be three phase, as it is more efficient to operate in an industrial environment.

    I'm surprised no one else has come forward.

    You could pull the motor and take it to a local motor service outfit and have them test it.

    Good luck and keep us posted. Once you get that thing up and running, you're gonna be super stoked.

    Thanx Chris.......you see my predicament with the motor............Just not sure ExACTLY what it is ..also seems as though maybe it's a two speed motor as there are two rpm ranges listed next to each other.,......I think I will be taking it off and having it tested.Better to know then guess and waste money.....I will keep you posted on the motor developments as they happen..But it's going slow..I've got 5 month old twins at home eatin up a lot of free time lol Sleep time too for that matter.......... Thanx again will keep you posted Jim

    Chris, Just checked out the Katt Motor website.........I get the feeling that Knowing how to speak German might come in very handy for using thier direct tech line.......But I may just try if my local electric motor guy deosn't have answers. Thanx Jim
