It looks very much like a ML7 changewheel version there is lots of info on Lathes.co.uk site. As for the oiler there a lots of tales of woe on their adjustment qualities but IMHO one of the best things to do with them is to make the taper very shallow on the needle making the adjustment much finer, enjoy!

Also 1/8″BSP has 28TPI – if you have a thread-gauge that will help if the thread crest is badly worn.

If the thread is badly damaged one thought is to use a thread file or restorer . It is a square length of good steel with teeth cut on 4 faces and both ends giving 8 different thread rates, though I’m not sure it will go to 28tpi. They are available in metric and imperial. The thread will be BSP 1/8″. Remember oil is cheaper than the unobtainable ML 7 headstock bearings. Good luck. Noel.

headstock bearings are avail in bronze

The ML7’s fitted with Tri-Leva and two speed motors as standard were definitely fitted with hardened spindles and bronze bearings from the factory, as were the capstan lathes ML7 based with two speed motors and ML7 headstock. The place I served my time had a number of both for second op work, the bronze bearings were very long lived running over three shifts per day, I can only remember one machine giving spindle trouble as a result of negligent oiling by the operator, some scraping and removal of layers of peelable shim soon sorted it out.

I’ve read this thread with interest as my Myford 7’s main bearings have only those “Rotherhams [of] Coventry” cylindrical pots with rotary lids. As far as I know these have no more than a small hole in them, so are basically just miniature funnels with lids.

I am now wondering if these are adequate or if I ought replace them with proper Myford ones.

Assuming of course Myford had not fitted those Rotherhams ones from new anyway.

All the other oiling-points including those on the countershaft have those horrible tiny sprung-ball gubbins designed to frustrate all attempts to put oil down them, and to spread it all over their surroundings instead. I just move the saddle well along along the bed, wipe the latter clean and run the saddle back over pools of oil, and this seems to work. Similar methods for the cross and top slide and the screws.

However, it is the headstock bearings I am now worried about, so would I – or rather they – be better with the proper wick-feed or needle-valve lubricators?
