The bushing is looking good. It's a good sliding fit on the shaft. Now I 
need a 7/16' bit.  I thought I might have one but no joy. It's about the 
same thickness as the fingers. I'll probably have to shorten it since 
the drill won't go as deep as original and a hack saw or dremel will 
take care of the slots.  I'm going to try some Permatex epoxy I have on 
hand I used for the filter repair.  If the glue holds, it will be better 
than the pot metal for the fingers.  I found the hss bit on ebay for 
less than $5 delivered.  So total of less than $10 plus my time which 
must be at about $3000 by now.
