Specifically a print cylinder and a new pad for the print hammer. Does
anyone know of a source for these two items?
The pad on the print hammer has disintegrated and the underlying metal
has been pounding on the print cylinder. This has caused some of the
letters images to be deformed so that only the top half of the letter
prints. A new print cylinder would be virtually impossible to fabricate,
so I need to find a new or used one.
I can try to replace the pad with something I have, because I don't want
to damage the cylinder any more than it already is. What was the
original material: rubber, leather? Anyone tried this before?
Ribbons are still commonly available though, I bought one at Staples for
US$2.97 this afternoon.

The last time I bought consumables for my ASR-33, it was from Western
Numeric Controls. They used to have the pads... I bought a couple
because both of mine had turned to jelly. Fortunately, that was in
storage, not in use, so I never deformed my print cylinder.

I have heard that people have successfully glued rubber feet (sold by the
sheet for attaching to the bottoms of enclosures) to the hammer. I would
be surprised if those lasted as long as the original, but with frequent
inspection, it might be OK.
The originals are rubber, BTW, with a lip to hang on the ring on the hammer.
You kinda slide them on from one side, then roll them around until the pad
lip locks around the hammer ring.

Right... fortunately, it's a *very* common ribbon (and it can be re-inked
if you really have to).

I remember when we used to get some that were dried out we would unroll them
and spray with wd40 to juice them up a bit!

I know people who did that... given that wd-40 is a good _solvent_, it
would work fine... not sure about long term issues, but as surface of
the print cylinder doesn't ever get lubricated, I can't imagine how it
would be harmful.
Just don't start spraying it in the works or you are likely to wash away
the proper oils and greases that _should_ be there (or at least be prepared
to do a proper lube job after you wash away any old lubricant).

I've been selecting the best parts for my 20mA DEC-interfaced TTY in favor
of the former-wire-service TTY w/110 baud modem (like the two boxy ones that
we got from you in NJ a couple of years ago)... I'd restore that one, but
long, long ago, I removed the touch-tone keypad and I didn't write down the
wiring arrangement... I _think_ I know which keypad it is (I have several),
but I don't know how to reattach it. So... in the meantime, the PDP-8 has
a TTY and my phone line does not (the DEC TTY has a reader-run relay add-on,
so it's not like I could use the second TTY as a console, anyway).
Thanks,

At least the military called the Typewheels. The FSN is 5815-027-4404.
$15, new in the package.
I guess you an Dan missed that box...

Unfortunately even NOS hammer pads have decayed by now (or at least the
couple I have have).
I am told that a stick-on rubber cabinet foot, suitable shaped and stuch
on the hammer, is OK for testing. No idea how well it will hold out in
use, but it will protect the type cylinder
to damage the cylinder any more than it already is.
What was the
original material: rubber, leather? Anyone tried this before?
Some kind of 'synthetic rubber'

All the Greenkeyers seem quite happy with simple stick-on rubber feet,
aka "bump-ons". They are close enough to the original density and size.
Electronics places sell them, eg. Fry's Electronics (evil thieves) here
in Fornicalia. Remove all the gummed rubber and degrease the hammer
lever with alcohol etc and it should last a long time.
The print cylinder, I have no idea. Someone might have a junked '33 you
can filch one from.
