Repaired the lift belt

Geo-TH,In · Jul 7, 2021

Keep in mind, this is the first time I've repaired a flat belt.
First I cut the old end off with a cut off blade.

Then I screwed 2 2x2s to work bench to position belt and clippers

Used 16 oz wacker to hammer clippers together. One side went straight to, the other side didn't. So I straightened the clips with needle nose and squeezed with vice.

Finally I gave it some adjustments with 48 oz calibrating tool.
Mission Accomplished.
If there's a next time Coldwell Bearings will make me a new belt. This belt is most likely the original, 1956.

Let the bowling tournament begin this afternoon when I

Get it back together.

In my Lab there is a South Bend lathe with a flat belt. It was originally a metal splice like yours. A new one was synthetic and skived. Thin angular taper overlapping where it connects together. The glue was only enough to make it bond, and it has been good for 6 years now. (the reason it comes disconnected is the dramatic difficulty of getting it on the pulleys if it was a loop. Jim

It will work until it doesn't, and it may not stop for another 75 years.

Even with Newbies operating it 7 hours a day. Jim

The old machines at the Sartell paper mill were run with flat belts, they ran on slightly tapered cone pulleys, so the belt could be shifted to change the draw. The widest belt was 6 inches and transferred a couple of hundred horsepower from a line shaft in the basement up to the machine. The line shaft was run with a 1,000 hp steam turbine. The splices in the belt were a long tapered glued splice, and they were cured in a heated press, and then stretched on with a 6 ton com-a-long. The were glued and cooked after stringing them around the shaft, there was always a spare belt off to the side ready to be stretched on after a failure. They ran like this up until about 2011.

Thanks. Neat info. I toured it once and wondered where the drives were. Jim

I have laced a lot of belts with my Clipper lacer.
You did very good.

Richard,
If there is a next time, I'll go all they way and get a new belt made at my go to store, Coldwell bearings.

I installed the belt. Let it run while I eat lunch. All is well.
My motor repair works well too.

All's good in my hood.
