[GreenKeys] supplier for 1" oiled paper tape for M33?

[robert.jarratt at ntlworld.com]

I have been using some non- oiled tape, but only very occasionally. Is it sufficient to oil the pins?

Thanks

There are two types of punch pins, hardened steep and carbide. Teletype used hardened steel and they need to be lubricated just like any steel puch.

Carbide does not need to be lubricated and can even punch steel, it does wear but not as much as steel.

If you put mylar (actually a sandwich of mylar and paper or mylar and aluminum) in a punch that has steel pins your punch's pins are toast and even
the block (the stationary part) throat is worn to where even new pins will no longer work. It may take more than one roll to do it but it will.

Not as bad as mylar but non lubricated paper will do the same thing, it just take a few more rolls to do damage, how many .. as far as I'm concerned
less than one.

Back in the days of  old with our monster TALLY punch that wailed on mylar as some unheard of speed it  would punch anything....
 
But  yea..  we also  need to  find a source of oiled  tape I was always  told  for the Teletype machines...  ( correct me if I am in Error.Ed#  www.smecc.org

Looking for a supplier of 1" oiled paper tape for the M33. Previously I'd found www.westnc.com as a vendor, but they now only carry un-oiled 1" tape. I've seen sellers on ebay and elsewhere with as-is old stock, but have heard it can be hit-or-miss if it's not been stored properly. 

West NC do carry oiled 11/16" tape - is this the correct stuff for an M28-KTR and M14-ROTR? Currently we have several rolls of un-oiled tape, but would like to be running the correct stuff through it - have only ran a few dozens of feet of the un-oiled tape through in the process of re-commissioning these machines.

Also, West NC do still carry roll paper for page printers, but if someone can recommend other suppliers as well, it would be appreciated. 

Thanks!
