Throw it in the junk and get with the times, it's called progress.

Hi Brett,
Yes, those are the epoxy type needles I was talking about. But I was
trying to figure out cheap, local sources for Kareem to experiment
with. Small Parts has neat stuff, but the requirement to buy $25 of one
needle size is painful, especially if you're trying to figure what size
you really need. Too big, and the ink will drain out on the paper --
too small and it clogs too easily.
Nobody's answered my initial question. Has anybody ever seen a
non-pressurized ink system using Teflon tubing for the feed line (unless
it's very fat tubing where the non-wetting properties won't break up the
ink thread)? But I got the impression the application intends to use
very fine flexible capillary tubing to aid in control of the ink flow
and I can't imagine using Teflon for that.
Regards,
Charles R. Patton
