[GreenKeys] Gears, gears

[Don Robert House]

In my experience that bit of play plus GREASE is used to "quiet" the  
noise.  In case something binds the fiber gear will loose some teeth  
preventing further damage.
When nylon is meshed with nylon many times the teeth will strip on one  
of the two gears.  I have never used a nylon gear with a metal pinion  
or vise-versa.
To do so would probably work but whether it would be quieter is merely  
a guess.  In all cases a good sticky grease is normally the solution.

I'm setting up my Model 28RO, recently acquired, on a new RO base.   
I've been working the gears between the motor pinion and the main  
shaft gear in a manner to have a tiny amount of slop between the motor  
gear and between the gear driving the main shaft.

This took a bit of juggling in order to accomplish the slight play so  
as to not have the gears tightly meshed.  However, I started to wonder  
if it is "permissible" to have a metal gear driving a mainshaft fiber  
gear.....a bit noisey.

Is there a "rule" about nylon to nylon or not metal to nylon???
