Thanks,what i meant was building a tranny basically.
Using an input shaft (with slipper ) with an input gear driving the diff gear via an idler gear i suppose.The diff would be as is,complete with outdrives.(basically think of a single speed e-maxx tranny with a diff instead of the output gear).

It would't be ideal for me anyway because i don't want the gear reduction,extra weight/bulk.
That's why a combined slipper/diff would be ideal.

i'm going to ask my friend Billy who's been giving me lessons on his lathe if he can help with a combined slipper/diff using your idea with the diff case.

Any suggestions for slipper pad material?Do you think brake lining/pads could work?

I like your slipper.the dominator collar is threaded on though so you can adjust the slipper easily but that wouldn't be a problem with a lathe.
