YEEEESSS!! This is my kind of thread right here! haha!
I would not do all this silly take this and then do this. Try and take a good look at the Odyssey Reloader and redesign how the clutch springs work on the driver, re do the springs, and for the driver bearing that habitually blows, make that bearing have an extra shell around it, like a metal bit that protects it in the actual driver, and a metal bit on the outside that protects the open side of the bearing. For the axle, yes, definitely go with the 17mm inside that has the true female option, that is good. but the main thing that is important about this is the way it engages, keep how it engages because that is flawless-atleast it always has been for me.
And as for using the same idea the Ezra does, dont. The derlin plate is made to be like that, they had it as metal i bet, and then switched it to derlin because it is a very hard plastic that does not wear out. I know people think it is that that makes the thing skip but it really isnt, it is the actual cassette ring missing the pawls, the way it engages as it rails the pawls upwards is different and as it pushes them up it isnt going to push them into the exact spot every time and will slip past into the next edge. Maybe use less wide cassette ring ridges if you are to do that so it doesnt skip. but i would stay away from that design personally.
And why would they automatically choose derlin for that clutch plate?? They didnt i bet. I bet they had it as a steel one and then encountered design flaws with that. That is my idea, i recommend that. But maybe im wrong about the Ezra thing, who knows.
