[Frameworks] Eiki SL-0 Maintenance Questions

[Jay Hudson]

I have two issues with an Eiki SL-0 that I need help with:

First, a common issue.  The rubber around the lens has disintegrated.  I
recall the advice was to get 'surgical tubing' and wrap it around the lens
in layers until it is thick enough.   What exactly is the tubing that
people are referring to?

Secondly, the projector makes a horrible rattling noise when it runs
forward.  Inside the projector, as a part of the bottom axle of the feed
arm, there are two cup-shaped gears.  Below that, there is a piece that
looks like an upside down comma.  When I run the projector in reverse, the
comma piece moves up and presses the cup shape gears together.  Run
forward, the comma piece does not move.  This is what creates the rattling
sound.  If I press the cup shaped gears together manually, there is no
rattling sound.  Until recently, I hadn't used the projector in years.  It
never used to have this problem.  Any ideas with what is going on and how
to fix it?

If anyone has any ideas, I would appreciate it highly if they could share
them.
