    Picked the lathe up yesterday. It came out of a school in Croydon, where I think it has been from new.

    Got most of the accessories it would of had from new:

    • Three Jaw
    • Four Jaw
    • Faceplate
    • MT4.5 > MT3 Taper Adapter
    • Travelling Steady
    • Live centre
    • Jacobs Chuck
    • Coolant Pump
    • Lovolite
    • Changewheels
    • Splash back
    • Chuck guard
    • All the C-Spanner’s and Chuck Keys
    Some damaged parts that you never spot until you actually have done the deal!

    Some damage to the L00 taper.

    Some damage to the compound.

    Damage to one of the screws of the four jaw.

    Damage to a jaw of the 3 jaw.

    Some Pics:

    So first things to do:

    Can I get a new screw for the 4 jaw Pratt chuck?

    Should I file the damage on the compound smooth?

    Need a decent tool post.

    That is identical to my one, I would lay money it hasnt done a lot of work. A few battle scars that will stone out! I would file the mangled bits smooth & leave it at that, i have seen far worse!
    A few tips, if you take the saddle off there is one bolt round the back underneath that is only visible & can only be gotten at if you wind the saddle fully to the left & I think you may have to take the gap piece out of the bed to get at it. I spent some time trying to figure out why the saddle wouldnt lift off!
    Clutch often sticks so worth stripping & cleaning.
    Did you get the manual & factory test chart with it?

    The chunks out of the compound won't hurt anything so long as there are no raised burrs. Cosmetic only. Any raised spots, even a tiny amount, will lift the compound off the ways and cause chatter, or if it's on the top will lift the tool post on that corner. Easy to check and fix but don't go mad with emery wrapped round a file or you'll dome the surface and make things 10 times worse.
    Chuck screws are hardened. I'd squeeze it back together and tig it then grind it back round.

    Thanks for your replies guys.

    Just getting this hideous paint off the tools first and giving the lathe a go over with a bit of diesel to loosen the old cutting fluid.

    Is the taper adapter meant to sit this flush? @doubleboost john perhaps you could advise?

    Completely forgot yes received the handbook. Put it to good use as it had drawings none of the manuals online had so I was able to identify some threads!
    Thank you for that!

    I may well take you up on that. Can you PM me some pictures?

    Less than a thou on the inside of the spindle nose.

    About a thou when indicating on the spindle (dinged up a bit).

    I’ve got a thou when indicating off of the back plate of the chuck. But saying that the backplate isn’t really a smooth surface.

    Looks like we should be okay.

    Perhaps @Pete. or someone with a steadier hand than me could come and stone the high points and check this compound slide for some pocket money?

    Thanks @doubleboost.

    I would like to get a larger fast motor or the two speed motor. Looks like it’s easy to swap. Would just have to get a different speed plate for the front.

    Between jobs today I’ve got to this stage.

    • 3 jaw completely stripped and rebuilt.
    • 4 jaw stripped - deciding what to do
    • Cleaned all the blue & yellow paint off the tools
    • Badges off machine - have started cleaning.
    • Cleaned muck off with diesel
    • Diesel washed off with APC
    • Rinsed
    • Started chipping off the horrible red paint that was flaking off.
    • WD40’d to stop any rust.
