They gave you a dimension to add to one end and subtract from the other end.

			Jim Kreider posted on Facebook, August 2018:

			: Here's some photos of the pin and bushing sets that I made for the Baker Valve Gear and sold along with the gear if a builder wanted them. Basically I have precision machined drill rod pins running in 660 bearing bronze bushings. Since you shouldn't press bronze bushings into bronze castings, I made precision slip fits between the castings and bronze bushings and then used bushing retainer pins to keep the bushings from rotating in the castings. The retainer pins sometimes were made to look like Alemite grease fittings as used on the prototype. Non-metallic thrust washers were used between interfacing bronze parts.

			: The design seems to have worked out well as there are many gears out there with many miles on them and showing little wear when using light machine oil on the gear pins. These pin and bushing sets were probably the first use I made of commercial CNC work.

			: The prototype used "fiber" thrust washers. The prototype NKP engines used Pilliod needle bearings while some other roads did indeed use bronze bushings.
