What are brushes made of? What's the process? I figure it'd be fun to make some and maybe make them of better quality product!

For what it's worth -
I was looking at an old Railroad Model Craftsman the other day, circa 1940s I think. There was a suggestion in a hints/tips column that brushes could be made from pencil graphite. The suggested using a carpenter's pencil because it has a big lead. They suggested soaking it in water to soften the wood to get the lead out.

That type of lead is way too soft in pencils today, maybe it was harder back then. But it would wear fast, gum up the gap in the commutator pads, and be a "short"-lived experiment at best. I suppose if you were TOTALLY without any other substance, it could be used, but like I said, it wouldn't last very long, or be very effective.
Slot car brushes of the older '70's cars are similar in diameter to the Tyco Power Torque motor brushes, I successfully substituted those for worn PT brushes and got several motors going again. Of course I had a supply on hand of those old style Brushes, but they are still reproduced today.
