[QUOTE="Marcus Bowden, post: 90254, member: 3287"] Roy's idea was my first thought, the other I use is a silicon brush end grain and it polishes up the commutator beautifully, then under cut segments of commutator.On big ships DC motors I use to put them in the lathe with a parting tool ground & mounted side ways then run saddle wheel to under cut the mica, some electricians I sailed with used a candle (wax) to & throw across the commutator as it was working and would prolong the brush life considerably. D & F connected together and put positive to D & F and negative to earth / body , this will polarise it to Negative earth connect and it should motor in direction to be driven, with a strong but slow RPM. Kick mechanical regulators into touch as one gets an additional 10 to 20 watts out of them. With added reliability. What I like about a dynamo is that it only produces what is required, with having Alton's on most of my bikes they produce maximum all the time with lighting on LED's my hand warmers are used nearly all the time, summer I ride with just the lightest touch on the handle bars otherwise my hands over heat, use what ever power you produce so that the regulators don't OVER heat and burn out, I've never had on go, but know several folf that have. bananaman.
