The new thrust bearing arrived so I've made a start on the front diff . So the parts I've made are
1 The drive pulley , made from Acetal , I shadow cut it as a copy of a hardened steel gear with a dremel tool then drilled it for the balls .
2 The left diff outdrive , its not finished , it still needs the slots cut out for the drive pin on the drive shaft .
The balls in the thrust bearing were 1.5 mm , too narrow for the diff pulley so I just used the thrust washers , these are the grooved type so they will help align the left outdrive , i used 2.3 mm balls in the pulley . The little thrust bearing is 2.5 mm inner and 6 mm outer .
Tomorrow I'll finish it off and maybe it will even work .

If a jobs not worth doing then its certainly not worth doing well.
A problem shared is a problem halved but an advantage shared is no advantage at all.
