Adjusting Nut for Boley Leinen Lathe

[jdrichard]

I set up my new Boley Leinen Reform lathe but the adjusting nut for the spindle does not lock as it is not a split nut and has no way of locking. I have included the photos. Would you know where one could get ine of these nuts?

As well, not sure if i can just acquire a machined nut and cut a slice out of it, compress it slightly and use this.

I'd try to find out what is factory and replicate that, I'll look at mine but I don't want to take it apart.  I have enough machines in pieces strewn across my basement and garage lol.

Making a nut like that is very easy for anyone with a machine shop, just make a drawing and get it made.....but first I'd want to know what about it isn't factory, and if it is factory, why it isn't working

I agree. It is so hard to find and data on boley leinen reform lathes and what the nut is supposed to be. Probably need a hand from all the resources out there. I have worn out the Google keys on my tablet.

JD, you require two thin nuts, one adjusts the end play of the shaft and the other is tightened against the adjuster nut to lock it.  You will require two "C" spanners to me the adjustment.

The nuts should look like these :-

Thanks. I can find these easily at the local “Ottawa Fasteners”. Have you done this?

No JD, I've not had the need to.

You may have to have them specially made to ensure the threads are correct and fit perfectly.

Ok, thanks.

Still will look for a split adjustment nut

Why not split the one you have and compress it slightly if you want to go that way?

I was going to get a nut that matches the one i have and do just that. There is a great fastener store 10 min from my house. Got all the hardware to bolt the lathe and motor to my desk

I’m not convinced that the arrangement you have is wrong. It may be that the locknut should run down a liitle tighter, but you may be able to deform it slightly to achieve that.

You could try contacting this guy who has infinitely more knowlegde of the subject than I do... http://www.lathes.co.uk/watchmaker/

On close inspection, it looks like the brass cover and the nut have been made as replacements.  The cover, appears to have been split with a hacksaw given that there are what appears to be linear scratching in the slot, and the depth (too shallow) and finish of the the threads do not look right for a machine made by Boley.
