    Default Lathe Restoration

    I have almost finished restoring my new old lathe. It is a 1978 Taiwanese lathe that I inherited from my late father inlaw. I managed to damage one of the oiling ports, a ball bearing on a spring. Does anyone know where I might be able to purchase them? The lathe was powered by a single phase motor, but I have a VFD and would like to put a three phase motor on to it. Does anyone have a 1 HP three phase motor they would like to sell?

    Michael,
    If you want to measure the hole diameter I may have one of the oilers to fit, I can post it across if required. I get mine from Atom Supply here in Perth, but they are a normally order in job. There is an Alemite part# but can't find it right now.

    Try fleabay under Business and Industrial/ Electric motors. There are generally a few 3ph low power motors going from all around Australia.

    Nice job. It looks identical to my lathe. Mine is badged Frejoth () sold by Repco in the mid 80's. However, I found they were made by Lantaine P/L in Taiwan. The manual is online at metalillness.com

    I too would like to run a 3ph 1HP motor (needs to be a 220/415v motor) off a VFD to overcome the belt changes.

    If you don't take up the offer I would be keen to fill the gap.
    Cheers

    Michael,
    Good work, I have recently restored a British Kerry lathe.
    Very rewarding work (although imperial bushes and bearings are a pain to get).
    I fitted a VSD to the lathe for the following advantages: Obviously speed variation, I programmed the lower limit to 25hz (half motor speed) and upper to 50hz. I dont want to overheat the motor at low speed, and the max speed is still a referance to the gearbox. This is great for thread cutting using the reverse switch.
    The other advantage is the quick braking time that can be programmed.

    Having also fitted VSD's to a milling machine and a wood lathe, the results are worth it.
    Remember that the 3 phase motor running from a single phase VSD needs to be wired in a delta formation to accept running at 220/240 volts.
    I tried old motors, but gave up and have used a good quality "oriental" made unit copied from a respected Euro make.
    Regards, Peter
    PS This is my first entry,

    Thank you everyone for the replys. 3 Phase and VFD is deffinately the way to go. I am not in a hurry, it has been an ongoing project for over 6 months. I will keep looking for a suitable motor on ebay etc.

    Hux, you are welcome to Pipeclay's offer, if he is agreeable. Shipping via Australia post will be about $50.

    Default Vfd's

    Hi Guys,
    Everyone is talking about VFD's as if they are a dime a dozen.

    I priced one yesterday and was told about $1000. Lots of Bucks.

    Are they available cheaply if so where say 1 or 2 horse.

    If the three phase motor is run on 240 V instead of 415 does this mean a larger motor is need as the output power is lower.


    Thanks

    A 2hp vfd can be bought for about $450.00 new. Where???? this has been discussed before. I suggest you do a search on VFD and see what pops up.

    If the three phase motor is run on 240 V instead of 415 does this mean a larger motor is need as the output power is lower.
    This depends on a couple of issues. If the tool motor is wired 415v Delta, then you will need another motor to run off 240v. To run a 3~ motor from a 240v active and neutral supply as we have in most homes in OZ, you will need a motor that can be connected as 240v Delta. This is not an issue as most of the smaller motors (under 5HP), if they are resonably new, are dual wired for star or Delta, . IE.... they can run on 415v if connect wye, and can run on 240v if connected delta. The VFD's I pressume you are referring to, accept single phase 240v from the supply, and then provide 240v ~to~ at the output side which happily runs the afformentioned motors at full name plate power, as long as the VFD is rated for the motor size used. My lathe runs a 2hp 3~ motor, connected as 240v delta, being fed from a rotary phase converter that supplies 240v ~to~

    Look for Delta brand VFD's. I recall a thread on the CNCForum where an Aussie quoted under $500 for a 3hp VFD from a Brisbane supplier.

    I have a Delta 3HP VFD on my mill and it works great (it was on it when I got the mill).
    I was quoted @$1k for a single phase 240v NHP 5hp 3ph 240v vfd.
    Cheers
