we were discussing small (0.3) mm printer nozzles tonight and I mentioned I
might be able to source some stainless needles to use as an insert. Heather
uses ones down to 27AWG (0.21mm apparently), however while trying to
explain the size we needed in non-technical terms I said "the size of a
fine paper-mate pencil".
Now could we actually use the tip of a mechanical pencil? Being metal It
should handle the heat, and already has an internal thread, available in
various sizes (0.3 to 0.7). could probably do with a bit of shortening and
possibly pressing a teflon dome over the end to give it a nice smooth shape?
What do you think? seems too obvious, surely someone has tried it already?
