Thanks for the feedback. I ultimately went for a steel version of the copper washer that is just visible in the middle picture. Despite appearances, its sized so the sliding dog slides over it. Thus, all dogs can engage fully and I have ended up with a final 15 thou end float on the mainshaft. I reason that its easy to pull the end cover with the gearbox on the bike so in the event of any problems I can easily investigate. The box is now fully assembled and adjusted and selects nicely so all appears well for now. I’m hoping to coax the clutch and gearbox back into the bike today. I have some other jobs to do but should be able to road test next weekend 😀
