I have cleaned some stuff up to facilitate cutting, (chamfers instead of outside fillets and purely cosmetic profiles for example), and modeled the spacer and got the mating geometry good.
I added four ¼” cuts 90 degrees from each other in the thrust bushing as I wondered how I would rotate the screwed together bushings to adjust caster without some tool. I imagined four because as the bushing rotates having more could be good as the tension arm might rotate over the cut if I only had one. In checking other bushing pictures, as far as I can determine only Elephant has a hex key cutout for what I think would be used for this purpose. I do not have any experience with adjusting caster bushings and don’t know if a cut for a tool to help rotate the bushing is really needed. I circled one of the four cuts in red in one picture. Anybody have any thoughts on whether the cuts could be useful or are they unnecessary?
