Bubble Balancer Fix

I was able to get some pics of the balancer. Thought about throwing a tire and wheel on it to show some balancing but the 10* weather was more then I could bare!
So here's the bubble balancer model I was taught on. As you can see its base is made in a triangle style with screw adjusters on the 3 bottom corners. I would put the tire on the balancer head and level the bubble to start.

Here you can see the bubble head and the circle and valve stem mark in the head.

When you sit a wheel on the top the main body drops down and since its a cone style it keeps the wheel centered on the hub. Again it was to cold to find a wheel and tire to show this!

Once I got to this point I would push the black lever on the side to release the head to the floating position. This is where I said the head floats in a fluid as seen below

I'll try to add pics of wheel and tire on balancer once it gets warmer. But this is the bubble balancer from years past. A lot of older guys think this was a better way to balance because the weight is not all at one spot and it makes a smoother transition as the wheel rotates. I've balanced and checked between the 2 (spin and bubble) and it doesn't seem to matter which one its balanced on the other way says its not balanced. But both do the job in an acceptable result!
