You make some good points that are very handy to know. I'm rebuilding a three belt 12 inch bench grinder, I'll apply this thinking when commissioning. Thanks for sharing. Regards Alan here in NZ
Yep, thanks for the tip yep and after the first year there's no tax on that. Hi, this is Frank down at fleco Technology it's late Sunday afternoon. I think I'll get on the lathe and see if I can turn some parts out
Perhaps many have not run across this, but when bias ply tires were the only thing out there, a condition that showed up especially in cold weather that when you jumped in your car and started driving down the road that there was a bumping or flat spot ride that occurred for a short period of time until the rubber was ‘exercised’ enough to smooth out the short term memory of the tire material from flat to round. I am not promoting radial V belts, but to say that Don is re-educating those out there to the why’s and where-for’s of machine operations. Same thing as letting your machine tool (or car) warm up to circulate lubricants before operations begin. Just things you learn as you go along!
I keep saying that about my old Axelson but I find another thing to do. I think you will find that helpful on the Clausing variable speed, the drives just smooth out faster keeping them at mid speed when done using and rotate off the belt set before starting.
So why does rotating the blade out of the "bump" in the belt before starting it cause the belt to straighten out faster? Just because the high torque at starting isn't applied to the belt in the same position? Maybe with the bump in the middle, the starting torque actually helps pull the bump out? That's the only explanation I can think of, but I'm not too convinced that's what's actually going on
Yes, that’s one of the most annoying things about belts. But the Reeves Drive in my lathe does allow it to run much quieter, even with the two speed transmission. Having that gearing buried inside the bottom of the lathe rather right on top majestic a difference. Unfortunately, my mill uses two belts with three pullers, so it’s difficult to get them aligned. But it’s mostly a problem with the one from the motor, which has a small diameter pulley at the top of the four different diameter stack.
The Pope Spindle Company had employees hand rotate spindles in stock once daily and recommended owners do that to installed spindles so the preloaded bearings do not brinell into the races "form dents" by working through the lubrication film from vibrations from other machines in the shop. The variable speed Reeves drive in the Moore was made by the same company that made the drive for the Rivett 1020, the belts are no longer available and have a different edge angle and width than what is available now. The cost of the belts was extreme 30 years ago, they are still good, I think it was good advice from Moore. Since, I rotate my machine spindles when not in use.

Thanks, It helps on the high speed machines
Good tip on belts. It’s good to see you again.
Hey, thanks!

Hi Frank!
Love this tip!
Glad it was helpful!

I have that old table saw running so good, I dropped everything and made a screen door for my house!
Thanks for that, definitely massive rain here on the west side of the mtns.
Still clear here, sometimes this area avoids the worst.
Thanks for adding this detail. You mentioned this but I didn't understand
Give it a try, thanks
Thats really interesting. I'll have to check that out on my Clausing Lathe. I finally officially finished it today.

Great tip Don!
Hi, thanks!
Thanks for the tip never knew this 1^ You have a nice day tooOOOOOOOO! :0
Thanks! You too!
Good morning Don….have a great week….paulie
hi, looking good so far

Most people will never even try this, and that is a fact. Thanks for tuning in.
Olá amigo Don é fantástico ver suas máquinas,sempre muito bem cuidads da gosto de ver e trabalhar com elas!!!
Abraço e boa sorte sempre!!!

@ honestly, I’ve thought about doing it, but never did. Your video has gotten me thinking about it now though.
