That is a tremendously generous offer Marcus, by stripped down = brake hubs and rim off?
Further inspection, after referring to David's supplied drawing (thank you) there is what appears to be the remains of the outer taper cage in the hub on one side at least and this has had the leading edge bludgeoned by some monkey, it maybe that this would preclude re establishing the taper bearing set up without removing, building up and re machining. Also, the speedo drive gear has been welded on !!.
All this makes me think that someone considered replacing the adjustable bearing and after subjecting the area to brute force, heat and a total lack of mechanical sympathy failed and reverted to the non adjustable bearing solution.
Am I right in thinking that the hollow axle would differ in length depending on if it was fitted with taper rollers or bodged non adjustable 'shady tree' solution. ?
I'll need to consider options and then maybe a short holiday in the beautiful west country.
