Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
The msg was dedicated to glassk but I made mistake on sending the post. Nevertheless all information that could help me to solve the vibration problem on my setup are welcome.Not sure to whom the request is directed. Don't think it's me, but if you need pix of my stuff, we're S.O.L. I'm out of town for another couple of months. Would be interested in seeing some pictures of your set-up though. Mine shook like a big dog until i got the idea of mounting the sleeve INSIDE the bowl. It reduced the amount of swing as it turned and moved the weight closer to the bearings supporting it. Still a little shaky, but nowhere near as bad.
Could you please send me a photo of your setup especially your balancer ?Centramatic wheel balancers install behind the wheel. Once installed, centrifugal force causes the shot and oil filled aluminum balancing ring to automatically balance the tire and wheel as you drive down the road.
Wheel Balancer Function
The free moving hardened lead alloy shot is bathed in a propietary synthetic oil. This two part combination moves automatically to the side opposite of the heavy points in the wheel assembly. The automatic function of these balancers can even compensate for mud, snow, and ice build up with the ability to correct front wheels that are up to 16 ounces out of balance and rear wheels up to 26 ounces.
I was thinking of a tube around the bowl filled with shot, of course if you had a lathe, you could build it in the coupling and then true the end and have stand by bowls for the kids to clean up

glassk, the link has one of the balancers like I make and use in the second photo. I calculated the rim speed of your examples and the 3450 rpm with 8" is 120.4 ft/second and the second, 6000 rpm is 209 ft/second. That will give something to compare to.
dikwks, how many rpm is your shaft, taking into account the motor and pulley ratio and what diameter is it? It appears to be about 14" in your photo. How did you determine your going at 2000G? That seems very high if you haven't balanced it.
As far as marking it with a marker and taking materials away thinking you are balancing it based on eliminating run-out, well, it better be low rpm.
