Ok, so I'm getting closer to my 40's/50's Mars Thor being up and running, and I have a question Re: lubrication of the spindle - what is the go with spindle lubrication on old plain bearing lathes like this? I've had the caps off and the spindle out the weekend just gone to fit a new flat belt, the journals on the spindle are in perfect shape, and the bronze bearings look to be in very good shape too - some marks from being hand scraped at some point, but very little wear from the looks. Now, I initially thought it odd that there was only one oil/grease cup - fitted to the cap closest to the chuck - when I pulled the spindle I learned that there is a et of passages drilled to feed the rear bearing from the front.
There is however no seals running anywhere, so slinging lube around the place is clearly the order for the day. I did put some 80w gear oil i had in it when I started the lathe up as a check, but I suspect there's something better? It's a curious lubrication fitting too - not alot of volume with the thread on cap off, and no provision for a wick like everywhere else on the lathe - I suspect it's intended for something thicker and screwing the cap all the way down acts as a pressure feed?
I should have taken some photos while i was messing with it.
