Going to balance my transmission drums and would like to see what you have used...

That's what I have & use for any part that rotates - mine is a Sundstrand balancer.

These are made from seamed pipe and I had to drill holes to balance them. I use 2 transmission shafts for the drake drum.

I borrowed a lathe at the juco to make these.

I cut the rod from a scrap axle shaft.

Mine work like Steve's. One has two different size tapers, and is reversed to fit different bushes. I do not have a fancy factory made set of balancing wheels. I hand ground the back edge of two 14" hacksaw blades to make knife edges. These are bolted to a frame using the original blade mounting holes. When balancing, I set the frame up on the level, and the drums roll on the knife edges till the heavy spot is at the bottom.
The frame is tall enough that I can mount a flywheel assembly using two transmission shafts, and those shafts become the mandrel on which the assembly rotates.
Hope this helps those without the balancing wheel equipment.

I have not done drums, but for flywheels I too use the knife edge like Allan. I took a paper cutter blade that I cut in half and mounted to a frame I can level.
