[GreenKeys] ebay .... Teletype ASR-33

Sat Apr 28 12:00:58 EDT 2018

Speaking of stuck, gummed up things:

I found that a hair blow dryer pointed directly at the suspected part
that's gummed up works wonders to melt down the old oil/grease and makes it
easier for you to clean it out or slowly drip it out as you replace it with
fresh oil (for parts that are hard or impossible to clean without
completely disassembling them, such as an M15/19's main shaft). An
industrial heat gun of some sort would work much better, but I've had good
luck with a simple hair blow dryer as I lack a heat gun.

Just a little trick I learned in the army. Actually, I picked it up from
the venerable Paul Cembura of RTTY Electronics.

Note that I have never worked on a 33 or any models that could be
considered related to one.
