My BTM lathe is a war issue version and the motor that is currently driving the lathe is about the same vintage as the lathe, and worst of all is huge and ways over 10kg.

I've just sold my BSA WM20 motorcycle so have some funds to put into new tools and would like to replace the motor for my lathe.

I was thinking about buying a Sherline lathe motor and adapting that, but I'm open to other suggestions. I know I could buy an old sewing machine and use the motor from it, but then I'm back to having a motor that is probably atleast 40 years old. I do want one that has variable speed, the foot pedal would be a nice to have, but not a problem if it doesn't have one.

Anyone have a better suggestion than a Sherline lathe motor, and no I dont want to spend £1500 for the Bergeon lathe motor?

Once I've got a new motor I will make a new base for the lathe and refurbish the lathe too.

Thanks Tony

I would try with a sewing machine motor,it can be adjusted right out of the box and is easy to mount on a plate or worktable. .... and soit  is cheap, even from new! You might have to change the pulley!

An alternative is to find a small standard 230V motor and mount it on a plate. It is also possible to use a small 3phase motor and then add a capacitor. The method also makes it easy to reverse with a toggle switch. If you choose the method so I will elaborate and throw a wiring diagram up!

      Epilame / Fixodrop

      By Klassiker · Posted

      I agree with @JohnR725. Oil on an epilamed surface is essentially the same as water on a waxed surface. The same physical properties are at work (surface tension vs. adhesion).

      Without Our Forum

      I think we all get a lot out of this group, and it has been pivotal in my development by the sharing of knowledge, experience and learning from more seasoned experts such as @JohnR725 and others (you know who you are!) as well as fellow novices. I think that having a backup communication plan in reserve so that if there is a future problem just makes good sense. I don't think anyone is trying to undermine the forum, but if something unthinkable happens, like the Ranfft website for example, then it would be good if those who are willing can still keep in contact. Speaking personally, and I know I risk a charge of heresy, it would be good if Mark could be a little more visible in this forum, and maybe give any insight from time to time on the future/progress of forum and instructional videos etc. even if its just to confirm the status quo. I appreciate he is a busy man with a full time job, but so are most of the rest of us and to post a few lines every now and then shouldn't be too much to ask to reassure the restless villagers. Best outcome for me would be a message saying something along the lines of: "Hi guys, all good, no planned changes... enjoy the forum, will message again next month!" Just my two cents.

      A nice looking watch !! Did you try 9010, instead of the 9415, on the pallet jewels / escape wheel? And if you did, did you notice a difference?

      Knocked out another 404 last night...when you are in the zone! This watch was a non-runner which I picked up as part of a lot of 8 watches, so works out to be $3.12 per watch. Before:   And the finished watch, new crown and stem and the crystal was cracked so was replaced. I also replaced the mainspring as the original was the old steel type spiral and very 'set' - all else is original: The Movement was a AS 1686, but in reading around a little the ACCRO watch company were sued for their use of the five point crown on their Jacques Pere range as it resembled Rolex, see below: ACCRO then reverted to just ACCRO on their watches - I have done some sniffing around the internet and haven't seen another example of ACCRO and the crown together on a dial so maybe I have something unusual, or maybe I was looking in the wrong places 🙂.

      Pocket watch escape wh

      By Bonefixer · Posted

      This watch was damaged when I got it. I didn't break the escape wheel pivot, and I bodged a fix with epoxy to see if I could get it running. I'm not yet ready to get into lathe work, or shellacking jewels, and may never be. But I'm learning plenty with each watch I tackle.
