spzero Posted January 23, 2016 Posted January 23, 2016 Does anyone make the electric pick up parts that wear down on the 9volt motors I have 3 motors that are no good now as they have done a lot of mileage, I would be happy to use them for power pickup or fix them as motors if the thin metal parts had not worn but can't even do that, Does anyone make or have the contact strips for sale or any alternative idea's TIA Quote

codefox421 Posted January 25, 2016 Posted January 25, 2016 This what you mean? http://www.eurobrick...howtopic=102241 I recommend using thinner wire than legoman666 recommends. I initially tried 0.025 inch phosphor bronze wire, which was too thick. It caused extra friction, slowing down and heating up the motor. I inevitably settled on wire of 0.02 inch diameter (about 0.5 mm) that I think is beryllium copper. (I don't know for sure because I got it out of a scrap pile at a local model railroad club.) Beryllium copper tends to be more expensive than phosphor bronze, but it has better spring characteristics than phosphor bronze, so to get a similar springiness at a lower cost use phosphor bronze wire thinner than 0.02 inches (0.5 mm).
