Have started on the Remington Portable 2 - first step of taking it apart. Well, at least as far apart as is necessary to replace the feed rollers, touch-up the housing shells, replace felt, deep clean etc. Putting a rubber tube on the platen would also be good.
Taking off the shells was fairly straightforward (taking pictures every step of the way, bagging every screw and part).
How to get at the feed rollers has me stumped for now though. Removing the paper table should ideally be possible without taking the carriage off the rails. As far as I can see the paper table assembly is screwed to the carriage base with a screw that is underneath the paper table itself.
It was the putting together again that I was initially worried about, but just taking it apart is puzzling already :-)
Any hints or suggestions most welcome. It's an intriguing puzzle...
