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
