do you guys take the weight / tension off of your lathe's drive belts when you are done using them for the day? i know band sawyers say relieve the blade tension so as to minimize wheel deflection. cars, however, have pressure on their engine belts all the time. just wanted some opinions on this - i've been relieving the tension on mine, but if it's not necessary, it's one less thing to hassle with / remember. as an aside - how many jet 1642 users have had to replace drive belts, and how often? thanks, mike

Have a 1642 - never released belt tension except to change speeds.... and I have probably only changed the speeds a couple of times in the past year.....I actually have never even heard of releasing the tension on the belt in order to save the belt.....YMMV

never heard of this either, thought I can't imagine it wouldn't help the slightest. Perhaps if you weren't going to use it for an extended period of time this might be an ok idea but still not necessary.

Nope. The belt tension on a 1642 is pretty low, just the weight of the motor. Really no need. Am told that a really bad catch can flat spot the belt if not shut off instantly, resulting in some unwanted vibration. If I ever get a catch I'll let you know if it hurt anything.

Take off the tension ??
I don't think it would do any good, I never do it, but if you do, don't forget ever to put the tension back on, or you will get a burned-up belt real quick, so there is a downside to doing it, but I suppose some people never forget these things :rolleyes: ;) :D

Gosh no Ken. Am pretty sure I had a catch a couple, three years ago.

What's a catch? The word is not in my vocabulary. ;)

I did loosen the belt on my Jet 1220 the other day, just because I haven't used it for a few months. I put a twister tie on the belt tension knob to remind me to retension it before use (I do the same thing on my bandsaw guide bearings when I de-tension it).

I haven't loosened the belt on my DVR xp because I can't find it. :rolleyes:

I've never relieved the tension on a drive belt, but I did regularly de-tension my bandsaw blade, on the advice of the saw's maker (Oliver).

you would only need to loosen the belt if there is a lot of tension, like mentioned with a sawyers blade, which i think has a couple hundred lbs of tension so the blade doesnt drift. you would only need to loosen the lathe if you had an enviornment where the belt would dry out and not run smooth from being left in the same position for a long time

Richard , great way to releave the tension ....:eek::D. In 40 years of Band saw tension the only time I ever did was with old model rubber tires , I had a Simco (? long time ago) that had a tension release but I only used it to change blades when i did something stupid ... the newer urethane tires do not seem to set/flat spot( if sat alot) like the old rubber compounds and the newer blades " keep on tickin" ...besides the price of a release "do hickey" is more than a good chuck and jaws ..... and a new gouge..:rolleyes: or maybe taking the SWMBO out to dinner now and then ....:o.

Mike, I appreciate your generous offer, and much as I hate to pass up anything free I must respectfully decline this time.

BTW I do detension my bandsaw blade between uses, but not with fancy doodad. The day after the new saw arrived I removed the useless plastic knob and installed a home made (as usual) bell crank. Nine turns off, nine turns on. No need to look at the "gauge" except after blade changes. Kind of a hassle though, so am thinking of motorizing it, maybe link it by remote to the shop lights. Ok that last sentence was just kidding again.
