Ok, well, i see our design goals a a bit far apart.

However, one thing it there that i want to ask.
You say you don't use the plastic syringe, how do you fill any dispensing
mechanism "air bubble free"?
I did not consider buying paste in larger quantities or in jars mainly
because
i think it is impossible to fill a syringe (or similar) without adding
air, which
would in any case (maybe air pressure feed a bit less) influence the paste
amount delivered,
and of course totally mess things up when the air bubble actually reaches
the tip.
