You would need to add additional balance weights or mill away part of the disc on the opposite side to maintain the balance.

Hi, I guess you could drill a few blind holes in the back and then fill them with lead. Careful calculation would be prudent though to get the balance correct, I would think. Tich wheels have a relief cast into them on the front side, so you could mill a similar into the same.

Regards Nick.

Bill,

Perhaps somebody will correct my comments but I would be very surprised if the counter weight makes a significant difference on a small scale model engine.

You only need to look across the available wheel patterns/ balance weight configurations to see a wide variation and as Nick suggests, a couple of blind holes would soon sort the difference out if you are really concerned.

Are you considering discs to save the relatively high cost of castings?
