 This is stale information and doesn't address your exact question, but
 I think at one point Keyways was selling replacements for the whole thing
 (including the hub I mean).  I don't know if Mitch Miller is still doing
 that, but there must be *some* reason for his owning the tu58.com domain name!

 I forget the price -- non-trivial but worth it, is what I remember.

 Otherwise ... do you mean to imply that people *have* been doing this on
 a lathe?  I'd be surprised to see rubber cooperate with that ... but I do
 have one (antique Sheldon BM-1026) and would be up for experimentation.

 Any idea how RTV silicone stands up?  It might be possible to cast new
 (fake) rubber on that way, although keeping it centered would be a
 challenge.

You can freeze the rubber material before turning it on a lathe,
probably with a sharp tool.  I've not done it myself at home, but some
of our Machinists have done it here at work.

Of course, you need to choose the correct durometer rubber for the
intended purpose -- TU58 capstans in this case....
