A neighbor of mine had an old Mercedes Airport Bus converted into a camper.? His alternator pivot bushing was no good.? I sent him to the local bearing supplier for an appropriate bronze bearing/bushing to make the mounting bushing to fit.? Used my U3 to trim the bushing to fit.? It was not the rubber and bronze original, but it worked and is still working 10 years later.
I make pens of all kinds including acrylic and wood.?
I make parts for amateur radio antennas a a shouldered spacer and end plugs for a 2m VHF? 3/4 Delrin turned to fit 1/2" water pipe to separate the two antenna elements and to plug the open ends
