Your so right. It is very addictive and you can pick these things up relatively cheap. I think I'll need a bigger workshop sometime in the future; my lathe count is already up to 3.

Funny you should mention SAE 660, as that is what I ordered in the end. Its what I use in my airsoft rifle gear boxes too.

Thanks Dennis but I am in the UK. I've just had a look at the PB price and it is £13.50+VAT for 100mm so not to badly priced.

I have removed the spindle and bearings. They were made by one of its previous owners using brass; a pretty crude affair to be honest but at least the shaft is ok thank goodness. The bearings were just bored out with no grooving or scrapping for the oil; just a hole at the top to let the oil in...

I'll have a look in to sintered bearings

Thanks guys. I think the best route would to be to replace the bearings as the history of the lathe is unknown and I don't want to break the headstock. So, I'm off to order and make a bloody great hole in a perfectly good piece of expensive phosphor bronze. Cheers Mat

I have recently purchased an ML4 and have noticed quite a bit of movement within the spindle bearing, 0.07mm when I moved the spindle upwards. So, I would like to make a new set of plain bearings. What I am looking for is a little advice, hints and tips as to tolerances etc. Cheers Mat
