    thanks lee. Was hoping for some kind of chemical, ive tried soaking in wd40 for 24 hours, scrubbing, if it means using cutting paste, I think il leave the stains there.

    ordered a couple of servo's for x & y
    http://www.aliexpress.com/store/prod...037562887.html

    intend to use a standard nema 23 4nm stepper for the quill (x)

    The spindle, is intended to be driven by a "vari-drive" pulley. This is essentially two discs, that are wound apart (by spindle speed winder)

    This picture shows the spindle pulley (with the top cover removed) here you can see the two discs


    a hand-wheel mechanism essentially parts the two discs, effecting where abouts on the diameter of these discs the belt grips, which in-turn changes the drive speed of the spindle



    problem is, I dont have the corresponding (sprung) pulley for the motor (or a motor for that matter at this point) I need something like this



    the pulley itself is NOT cheap. new, as a set of parts about (300). As I intend to drive a motor via vfd I may just scrap this mechanism? thoughts?

    below this, there is a back-gear, that I can still utilise even if I remove the variable disc arrangement and replace with flat pulleys?


    FYI, if anybody is interested, I note the seller has another one for sale.

    On my KRV, I have used a VFD too. I still use the back gear on it which gives some serious torque gains.

    The real question is if the motor you select will be able to give you the same amount of torque in the low frequency range as in the normal 60Hz range. If it can then go with a HTD type metric belt and pulley system. You can then keep the back gear too.

    3.) The clear hose coming out of the body of the machine, goes up to the quill, and the black line you can see seems to go to feed the network of lubrication lines plumbed into the machine (both these feed lines are not connected to the oiler, and are just loose. and I dont know where they would go)
    4.) It is marked 110v, so I guess Il have to use one of those yellow site equiptment block things to power it?
    1) Looks like a Bijur, however they normally have a manual primer.
    2) Slideway oil during normal use. A good quality 68 should be good, or 220 if you plan on doing lots of knee moving (68 isn't rated for vertical ways, but 220 will cause a bit dragging on other ways)
    3) I'd say there's a T-piece with another metering valve missing, unless the metering valve is mounted elsewhere i.e. on the quill.
    4) Yellow block, or just get a small 240-110V transformer if that's the lube is the only thing going to be running from 110V. You only need 4W, so you should find a suitable transformer for less than 10.

    Given the age and lack of use, the metering valves are likely to be blocked. First up, I'd disconnect all the lines going to the metering valves and make sure they're clean. Then fill the lube unit with some ATF, and leave it running over night. You can then check to see if there's red oil on the ways. If not, then you can try cleaning the metering valves with some carburettor cleaner, but they'll most likely need replaced.
    Once you're happy oil is getting everywhere it should, drain the ATF and put in slideway oil.
