    Hi Neil

    Some good suggestions there. Machined surface with fibre makes a lot more sense and I could make something if all else fails. I'll try a bit more PTFE then look into the locktight.
    Oil is what Warco recommend for their headstock and cross slide. Have a look in their website as there is only one.

    Pretty sure it is dripping out the plug. The front face where the shafts exit is bone dry. Underneath there were lots of drips gathered around the plug. But I'll double check.

    Strange how your lathe does not have a drain plug. Mine has a similar plug on the upper left side of the carriage to fill the oil and a sight glass on the lower right side. It has power feed and power cross slide.

    Thanks all

    My lathe is in bits at the moment (not completely). I had a loud constant screeching noise coming from the motor area, which I assumed was the bearing on the cooling fan.

    So I decided to replace it.
    To do that I had to get behind the motor,
    to get behind the motor I had to take the motor off the mounting studs,
    to get to the mounting studs I had to take off the electrical box and lift the lathe off the swarf tray by about 100mm.

    I also found that the VFD mounting lugs had broken and the thing was hanging on it's wires. So I have 3d printed new mountings and araldited them to the VFD case.

    This is where I am now, waiting to reassemble. I have a new cooling fan despite the old one working perfectly once out and on the bench. (it must have been swarf in it).

    I have some 100x50x5 box section and my intention is to make some raising blocks to lift the machine 100mm from the swarf tray to allow me easier access for swarf removal (and repairs if necessary). It also puts the centres of the machine at a better height for me.

    I am just waiting for my persistent cold to subside and my arthritis to ease to put it all back together, I can't face a cold workshop at the moment.

    Make a plug with a shoulder and use a Dowty Washer/Seal, job done! :D
    Regards,
    Nick
    You think that's too expensive? You're not a Model Engineer are you? :D

    You could try a copper or aluminium washer, or solder a steel washer on the shoulder and use an O ring.

    Why would you bugger about with something else?

    Nice idea Nick - added to the to-do list.
    Found some M12 Dowty seals on e-bay £1.95 for 2. Need to check exact bolt size before ordering and I'll knock something up over Christmas hols.

    Check your local industrial Bearing and Seal supplier, you'll probably get 10 for a fiver ;-)

    I have been having a few issues with the tailstock not ejecting tools. I found the problem, but can it be improved . . . ?!

    Finally after a 6 month wait the microprocessor has arrived from TI. Time to get going on this Electronic Leadscrew Project!

    Big thank you to James Clough for all the R&D and working it all out.
