[GreenKeys] Model 19 gears

[Kevin H. Phillips]

I'm making progress.  I took the typing unit off again and worked the 
main shaft by hand.  The clutch "appeared" to be working but I applied 
liberal doses of oil to it and to the area underneath the magnets.  I 
also removed the cap at the end of the main shaft and dripped oil down 
the center.  I put the typing unit back on the machine, hooked 
everything up, called up ITTY, and let it start printing.  This time 
after a few lines it started copying mostly correctly.  The LF had not 
been working before and it began working as it should.  The typing 
basket had been advancing only about half-way down a line and now it is 
going to the proper end. CR & LF seem to be working as they should.  It 
is typing pretty well so it is obviously 60wpm.  The only "major" 
problem now is that the ribbon isn't advancing and returning so it just 
types until it pounds a hole in the ribbon.  I'm going to let it run 
open for awhile and see if that jars the mechanism loose.  I had put 
quite a lot of oil on the typing basket/head so it "should" be well 
lubricated.  There must be some residual guminess somewhere.
