Tips/Techniques Another way to make a surface grinder balancing ring

[Susquatch]

When you guys are balancing your wheels, I assume the radial hole set screw ring stays put for both the initial run in (thus dressing the wheel OD perfectly radial to the shaft center dictated by the ring/arbor) and then directly to the balancing bars for set screw adjustment?

I think @Dabbler's reply nails it.

But I share your concerns anyway. The hubs on all of mine are tight. But I don't think it hurts to be a bit anal about the positioning.

It turns out that there is more variability in the OD of the hub shoulder than I expected - especially between different hub manufacturers. So each balance ring should really be customized and mated to its own hub. The Precision Kinetics balance ring is designed to address that, but I'm not about to do what they did. Another plus for epoxy I guess.

I didn't really address all of your question.

My process (which may not be like others or even right) is:

True the wheel with no balance ring.

Install the ring and balance.

Retrue the wheel.

Rebalance the wheel

Retrue the wheel.

I wanted to revive this thread just a bit to show @Susquatch robin renzetti's simple to build balancing jig.

3 steel plates, two precision ground rods and a 3 point foot system.

Thanks. Nice short video with a crap load of content. I really like that!

I think my jig is even simpler. Two posts using my tramming blocks, 4 small V-Blocks, and two ground rods. No welding, no machining, just dirt simple and works great. It worked so well that all my thoughts about making a dedicated fixture evaporated the first time I used it. I'll take some photos next time I'm in the shop.

His balancing ring deserves much closer scrutiny. I think there is much more there than meets the eye. I like it!

@TorontoBuilder - as promised, here is my balancing setup. Dirt simple. No need to make and store a special fixture.

Note the thin plastic sheet between two of my home made 246 blocks and my surface plate.

The screws in the V-Blocks stop the arbour from rolling off the blocks. You only need enough ground rod to roll the arbour 180 degrees in both directions.

If I ever make another arbour, I'd make the shaft on the left side longer to center the stone more. I might thread the shaft on the right side too.

So this is your balancing room. Nice.

I see your blade balancer:


PS - as we age we hopefully won’t become unbalanced

I see your blade balancer:

Yup, that's it!

here is my balancing setup. Dirt simple.

I get my new Baldor grinder on Friday - I will need to balance the wheels (with or without getting one of the OneWay balancing systems like the one @Ironman suggested).
I just cobbled up this setup, seems to be quite stable. Uses 3 fine thread nuts & bolts to quickly get it level.
Here’s a couple of general view pics:
and a few close-up looks:

The rod on the sq tube has a couple small magnetics to help it from rolling off and the bolt heads in the axle stands have a ground-in grove.

That will get it done.

I didn't like one way's balancing system that much, too cheesy with their standard nuts and washers. The real dislike was the 1" bore.

I have a slew of wheels, all with 1 1/4" bores so I wanted to have a hub that was the same size as my surface grinder wheels. Easy enough to make your own, and you can cut curved weight segments from a ring that you turn.
