I picked up a nice Decision Data model 8010 keypunch machine through 
It looks to be in good shape EXCEPT some rollers have turned to goo. 
They act just
like peanut butter, looks like it too. These are not simple round 
rollers but are tapered,
and there are 16 of them in a complex arrangement. Any ideas on how to 
fix them?
I guess I'm going to have to find some suitable plastic and turn them on 
a lathe. Probably
beyond my ability.

Here are some photos:
