I was lucky enough to recently acquire a Boley F1 lathe but the belt is needing replacement.  Does anyone out there know where I can purchase belts for this type of lathe.  The belt I have is round rubber 3.5MM diameter with a total length of 265MM.

Any help is appreciated.

Thanks,

Bob

Most of us use polyurethane belts nowadays, although there are sone who swear by leather belts.

You can get a unjoined length, cut it to size and fuse the ends together. There are plenty of videos on YouTube showing how it's done.

That sounds like it might a sewing machine drive belt.

Just Google "3.5mm rubber sewing machine drive belt" and see what comes up.

Hector,

I have seen the videos on joining the polyurethane and looks easy. 

I ask this one question out of ignorance.  Does poly have a stretch to it?  I was assuming the belt should stretch to help with vibration.  If it doesnt make a difference I am in with polyurethane.

Thanks,

Bob

Hi polyurethane belts have a little give.  Move the motor to the closest position then fit and join the belt. Method I use to cut it slightly over size, fit the belt over the lathe pulley, heat a blade and press both ends of the belt on the blade and when melting slide off the blade and press together. And hold untill cured. Then fit over the motor pulley and adjust the tension. Do not over tension as it outs strain on the join.

      9020 or HP500? Which would I get the most use out of?

      By Simeon · Posted

      I did wonder about the feasibility of mixing two oils. I am guessing that 9010 / 9020 or HP500 / HP1300 would be a better mix than 9010 / HPxx. Some people might think that was heresy but I guess the only consequence is that you might have to service the movement again if you got a poor result.

      Yes, however, as you are just starting out, you can progress using Ronsonol lighter fluid (or equiv) to clean.  Use pegwood to clean all pivot bearings. Yes.  Some disagree with me.  I have many hundreds of dollars invested in multiple time graphers and vintage timing machines.  The phone app is just fine for a beginner. Probably just needs a good cleaning. My SWAG, is slim to none unless you own a 3D printer and can design and print a spacer

      Chances of fitting that movement into a modern case with pleasing results are not good unfortunately. Dial size, pinion height, the position of the stem relative to the thickness of the movement all play a role, so cases made for a specific movement are really only workable for that movement. If you have a lot of skill in 3D modeling you might find a way to make it work, but it would be a significant challenge. A case made for an ST36 would be gigantic in relation to the Benrus movement. A case made for something like a Seiko NH35 would be closer to a workable diameter, but most of those modern cases are made for automatic movements that are much thicker than vintage hand wound movements.

      Thank you very much for the very helpful info, folks. A lot of reading to do! I do like the look of that ingersoll. I am in the UK, so I think moebius is more readily available than Elgin. I hear 8000 does the trick as a jack of all trades. Given the rather sorry state of the Benrus, if I get the movement to run (If wound, it ticks for about 2-5 seconds then stops. Give it a tap, it ruins again, then stops again), What are the chances that I'll be able to fit it into an ST36 case (perhaps with a 3d-printed adapter)? I don't think I'll have the spare cash to invest in case re-plating and dial re-finishing! I would really appreciate some info/links on how to clean the parts: is it achievable without a ultrasonic cleaner, or am I better off buying one and not wasting my time? Also, can I get away with a timegrapher app on pc/phone?
