The tandem bearings are ready. There´s a split outer ring attaching to the tandem box, an inner ring attaching to the rear axle and a bronze ring there between, fixed relative to the inner ring. The bronze ring has the same dimensions as a certain "standard" 4-point contact, thin section bearing with a split inner ring. Unfortunately, however, the only supplier I know of couldn´t deliver .

To the left the two faces of the outer ring.










At the end I decided to split the bronze ring and make a one-piece inner bearing ring.


Finally, everything fits.



Making of

The bronze rings were made first, to allow for easy test fitting with the other rings.










The main outer ring portions being parted off.




Test fitting during grinding.



The stub was barely long enough for machining the other outer ring portions.


I hate making thin things. Either you have this rather insecure and hard to adjust grip or you have to make a jig.




This threading apparatus is really an excellent tool.


Thanks for looking.
