[GreenKeys] First Teletype Machine! Here!

[W2HX]

My 28 ASR also spaces along when its open. I think its ok, probably just an
optional tine or pawl or jig or thingamagiggy

Typically, the carriage shouldn't space with an "open line". It would
just
sit there and chatter. Once you check all of the clutches and so on,
perhaps you'll get it to sit still(!).

I know this would be considered heresy, but when I worked for
New York Telephone in the TTY gang we put the typing units in
a dishwasher, platen, coils and all.....we'd then blow it dry
wtih compressed air and give it a good lube job. Worked every time.

There's as many ways to clean a TTY as there are TTY enthusiasts...

Thanks for the cleaning suggestion!  I was dreading breaking down the
machine to clean each part.  Soaking the unit for a few days seems
like
the right way to go.  Should I remove the selector magnet assembly
from
the typebar unit before placing it in it's bath of Kerosene?  Other
pages on the net mention trying to keep the selector assembly out of
water and other cleaning solvents.  Any thoughts on this? I understand
keeping water away from the selector magnets, but what about Kerosene?

As far as the carriage return "issue", I assume that the machine isn't
going to strip its gears or cause other "self-inflicted" damage
pushing
against the right margin all the time.

When I get to the lab again this afternoon I will look at the spacing
assembly for the stuck bits.

Thank you for all your help!  I wouldn't have even thought of
purchasing
one of these if you guys (greenkeyers) were around to provide advice.
Seriously - Thank You all.
