Jet1442
I bought a Jet 1442 about a year or so ago and, for the most part have been
pleased with it. I turned the handled for the Reeves Drive around to get it out of the way and have replaced the bearing on the head shaft (it sounded noisy, but was a loose pulley and not the bearings), but other than that done nothing, until this past weekend. Now for the question. The Reeves Drive has quite a bit of travel left when you put it in the last detent (450 RPM). The belt got stuck in the pulley and did an auto adjust to about 2,000RPM, instead of the expected 450RPM, to the determent of a floresant tube when a piece of bark hit it. So, while I had it down getting the belt unstuck, I decided to drill two more detents on the slow side of 450. Seems to work great (I have not figured out exactly what speeds I now have yet - I had turning to do!) but it seems to have slowed the lathe down without any loss in power. Is there any reason I should not run at those new lower speeds? Deb |

I wore out a couple of belts on my Delta and finally put a link belt on it and it ran quieter and never showed any wear as long as I used it. (I have a newer lathe now, without the Reeves drive). -- Gerald Ross Cochran, GA Animal testing is a bad idea: they get all nervous and give wrong answers. |

If you know someone who has a photo tachometer, you might check the rotation speed when in the 450 detent. My guess is that it's higher than 450rpm. I can take my handle slightly below the 450 detent, but it doesn't significantly slow the lathe. I'm guessing it might be around 425rpm, but probably no lower. Just a suggestion. Max |
