Slipping drive on Jet 1236 lathe

>Guys - Purchased a slightly used Jet 1236 lathe a few months back. Have noticed that on larger diameter bowls, the turning slows and sometime stalls due to my agressive tool use. Motor doesn't seem to labor, as I watch the motor fan with one eye , and watch the lighting in the area (which shares the same circut) and no light dimming or motor slowing is noted. Appears the only way to tighten the belt is the spring on the motor pulley assembly, which won't be easy. Do belts wear out in this sort of drive? Is the belt supposed to be a cut-side or wrapped side belt? Or is this slowing situation the nature of the 1236? What's your experiences ? Thanx......

>Pete,

Mine does the same thing, because I have lubed the shaft and bushings so the Reeves-type drive will continue to work. Some of the lube was a spray-on dry graphite (dry after carrier solvent evaporates), and some got onto the belts. I have left it that way because I do a lot of delicate thin-walled hollow forms, and the slippage adds a safety factor.

A previous owner of the lathe may have added lubricant to your lathe, so you may have the same situation. You can get some spray belt cleaner from an auto parts store, and that will give your belts a little more grip.

I'd also make sure you're not taking too big a bite when roughing, and doing so with a sharp tool, which will also reduce belt slip.

Safe Spinning,

>Hi Pete,

No, I never had any lube near the belt, however, cleaner may help. I have a similar problem occasionally on my sewing machine (big industial monster). Sanding the belt a bit to remove any glazing & give better grip seems to help.

>Yes Pete the belts do eventually wear out... the best replacement belt I have found is the Gates 3L240, you can buy it at just about any auto parts store for about $5.00...It was recommended to me to replace the belt at least once a year even if it does not show signs of wear.. and at $5 each that is not a bad investment.. also as stated be careful about lubing the area around the reeves drive.. you don't want any lube in the pullies or on the belt..

I got the info from the site below..
