QUOTE (dgersh @ 8 Dec 2011, 14:08) <{POST_SNAPBACK}>I can see traces of what looks like epoxy, but not enough to be sure, and certainly not enough to balance the arm (theoretically, it had to be weighted epoxy to make any difference). Also, the wire seems a bit larger than stock, but again, not enough to really be sure - I'll let you know after I test it this weekend!

The static balancing technique they used back then wasn't particularly high tech and didn't need weighing as such. Might sound a bit crude, but the guys who knew what they were doing made motors go quite a bit better that way.
Essentially put the arm on a pair of razor blades, and add epoxy to the light side till it's in balance. The amount of epoxy needed depends on how far out of balance the arm was in the first place. That could be very little or quite an obvious amount.
The alternative was put the arm on a pair of razor blades, find the heavy side, drill off some metal and try again till it's in balance.

Dynamic balancing needs higher tech equipment, produces better results and these days is readily available to slot racers for a few pounds. That'll be why those forms of do it yourself balancing have pretty much died out.
