Well, as often happens these days, I am a bit asea.According to the Logan manual, my belt is listed as 39" long.My lathe currently has a 6K408 belt on it.Specs list is as being 40.93" effective length, and 41.53" outside circumference.It w0rks fine. Should I purchase a 41" belt as a spare??

Use the old belt as a gauge to determine the size required.

I have a '47 South Bend 9A and a '45 Canadian Moody (11x48). I converted both to automotive serpentine belts used rubber side down rather than flat leather belts. Zero slippage. Belts can be run much less tight, with less strain on pullies. Both lathes feel like gear driven heads with these belts. I can't remember where I read to try this, but it works so well, I use them on both of my lathes. If you're on a tight budget, broken serpentine belts can be obtained at any garage. They're going to be cut to length for your lathe and laced anyway.

I had bought one of the E-bay Squirrel Daddy belts, but it slips.TIA, Keith
Hey OT. Next time it pulls through I think I'll try and glue a strip of something to the flat side to splice instead of the aluminum wire splicing. Something like heavy mill canvas glued to the flat side about 2" on either side of the splice would spread the load across 4 square inches instead of the thin wire. I just have to discover some kind of magic glue that bonds well, is highly resistant to shear forces, and still remains flexible without fatigue.Did yours squeek? Mine do. Try chalk.
Yeah, my Logan came with a serpentine belt installed....I'm just concerned about replacing it should I ever need to......

Try chalk.So why not use a strip of belt to sew in like a seatbelt? My vision is ribs touching the pulley with the smooth out. Then take a strip how ever long flip it ribs out and use some very strong thread like what is used in ratchet straps or seat belts and stitch it in.
