[Frameworks] Eiki SL-0 repair?

[Zach Poff]

I'm not a veteran projector tech, but I have found that my SL-0 often 
needs lubrication inside the telescoping tube under the lens mount that 
slides forward/back when the film path engages. Old lubricant gets 
"chalky" and the resistance is enough to make the main knob stiff or 
impossible to turn.

In page 53 of the Eiki service manual ( 
http://www.film-tech.com/warehouse/wareview.php?id=1480&category=2 ) 
you'll see the pin that slides inside a tube called the "reception 
bracket guide bar". Take it apart, clean it out with alcohol on cotton 
swabs. I lube it with silicone oil (although I don't think the service 
manual mentions any lubrication in that spot). If you use common 
petroleum-based oil or grease, it will dry out again in a few years. 
Synthetics like silicone oil or PTFE grease (Superlube in the US) will 
last much longer.

I should note that it's probably the tip of the iceberg. There are many 
points that need lubrication, so other problems might be on their way 
(especially if previous service was done with whatever lubricants were 
at hand).

Hope it helps!
