I would agree, if I can get them apart non-destructively. The metal cap
on the back end is crimped on (like an old milk bottle cap, but thicker
metal). I may have to cut theat off and make a repalcement. I do not want
to break the glass tube, although it may not be too hard to make a
replacement for that either.
Does anyone have any suggestions as to how to
make ink cartridges for
this machine?
Given that description, and the fact that you have three cartridges,
surely the best way is to re-fill the one(s) that you've got? In which case, the question is really "what's
special about that ink?"
It must be conductive, for one. Lots of carbon black in it?
A friend driected me to US patent 4332487. This is clearly not the same
printer, but the principles are the same The ink is indeed conductive,
and is indeed mostly carbon (95%). Various binders are suggested, no
details of shick one is used are given.
I wonder what pencil 'lead' would do here...
