Found a supplier of anodizing and plating services up in Chonburi called Thai Silvec. I kind of got the impression they’d never had someone just walk in the front door with parts that needed plating and anodizing, but they accommodated me just fine. Very serious Japanese management, everything organized and clean, and reasonable prices. They gave me a detailed quality report when they delivered the parts, so now I know just how much allowance to leave for plating a mating parts. For next time, that is. This time around, I’ve had to do a lot of hand work to get everything to fit due to the stack-up of plating and anodizing thicknesses. At least I had them mask the wheel bearing bores, so the bearings later pressed in smoothly.
