Received my tumbler gears yesterday and not really that happy with them. The width of the gears, wider, does not allow for the use of washers that would take up play. The 24T roller bearing pops in an out of the gear and bore size is .040" oversize of the 1/2" shoulder bolt. Same sloppy play with the 20T bronze bushed gear and can't use washers or it will immobilize either gear against the selector body. I lathed down two change synthetic gear bushings to fit the old Zmak gears and seems to work fine "so far" ever though lathe is not running yet. Now my problem is the nylon compound gear fitted to the Zmak gears has zero mesh clearance and very difficult to rotate. I tried lathing the gears outer diameter but found out real quick that nylon doesn't like to be lathed! Anyone have any ideas on how to decrease the gear diameter for mesh clearance?
"Maybe" the nylon will just wear in. I'll put some grease and very fine sand on it and maybe it will help the wearing in process! "NEWBIES" PLEASE DON'T DO THIS AS THIS IS A JOKE!
