Drum will be empty except for the rod running through the middle. Doesn't have to be too accurate, I just don't want it visibly wobbling or shaking the fixture it's mounted on.
Length 34", diameter 23" as is. I'm going to put some vanes on it, so total outside diameter maybe around 33" or so. Total weight probably less than 100 lbs, max RPM should be under 500, probably more like 200. At later stages that could increase, but for now I don't forsee it spinning any...
I'm in the (very early) prototype stage of designing a machine with a rotating plastic drum, specifically a 50 gallon drum. It rotates about the long axis. How would you go about balancing this? I'm thinking take some careful measurements and stick a rod through it, then fine tune it with...
