A guy who is maintenance for one of my customers came up to me with a project. Someone in his family, maybe dad or FIL, not sure, has a older model power wheelchair or scooter. The original aluminum drive wheels that turn the rubber tires wore itself bald and slips alot. He went to buy more but company discontinued that part.
I normally try not to do cash work for individuals, since they usually want custom machining for something at production chicom pricing, but if the guy is handicapped, and having trouble getting around, and I can help, well sure, I'm gonna.
T-Dad 1066 told me as a youngin, "always help out the old folk, one day you gonna be one".
