Hi Furgus, I would have drilled and tapped the pulley directly over the key. That would stop any movement of both the key and the pulley.

Having said that I've also seen a screw put into a shaft to stop a pulley moving. In the old days a tapered key would have been used and hammered in. You might have seen them on old machinery, they had a raised section on the end so they could be extracted.

Looks like you are sorted now but I converted my AUD to a inverter/VFD a few years ago. Probably the single best upgrade ive made to the boxford. It runs so much more smoothly and is a lot more convenient to use now. I would highly recommend it. A project for the future perhaps.

On the bearings, don't cheap out! Its not worth the hassle. Try to get decent branded ones. (FAG, Timken, Koyo, SKF)

Bearings is really a matter of choice sealed or not they are normaly grease packed for life,, Prices depends on the dealer if this is a large concern they are normally cheaper , Trade prices can be as much as 80% discount,

Good luck

Thanks, believe it or not I've got a Jaguar CUB inverter on order from Pete Moss at Transwave. I just need more control. I really need the best I can get but also have to keep my head during this lock down. Crazy timing I guess, not just for me.

Regarding the bearings, I've been looking at SKF at Simply Bearings. Quite a price range. I could pay £90 for one but I think that's out of my league and perhaps overkill. Maybe they're for marine use or the auto industry? Anyway I have to get 6 in 3 sizes so I'll try and get the best I can for around £30 a pop. They'll probably last as long as I use the lathe and maybe I'll be in a better place to buy higher end once they wear.

I'll update once everything arrives and I reassemble the lathe. It's at least comforting to know it's spotless inside now… for a while anyway.

[Fergus DavidsonParticipant @fergusdavidson50660]

Finally everything arrived after the 3rd attempt at ordering a sealed bearing and getting an unsealed one through the post.

The inverter has taken the lathe into another realm. Quiet and hopefully more efficient. It's at the very least good to know everything is clean and functional.

Thanks for all the suggestions. Here are three photos .

Well done sounds good bet you are pleased with your work, Just keep a watchfull eye on all you have done any noise that you are not used to have a look and find sometimes saves a lot of work later.

Nice to hear a success story.Regards Brian.

A bit late to join in on this one but in some of the early photos it looked as if the pulleys were misaligned, if you use a straight edge on the side of the pulleys you can check that the pulleys are in the correct position along the shaft and that they are parallel with each other. Make sure you allow for any difference in the thickness of the pulleys. It is surprising how misaligned pulleys will try to walk along the shaft. You may have found that the motor had moved and was generating your original problem. Glad you have it running sweetly now but could still be worth an alignment check.

Will do. Thanks again one and all! I'm not going to miss anything any more if I can help it.
