Hi,

we discussed that ages ago.
Has anyone built one successfully?

I think it would be cheap enough to build to solve many uniformity issues
by using multiple sprayer tubes and motors.

They are not too expensive at ebay (around 100eur), but i asked and the
motor mount is stainless steel, so it's a no-go for CuCl.

Any ideas how to make bearings for the sprayer tube out of CuCl compatible
materials? A titanium rod maybe turning in some plastic (non nylon)? Would
that seize up or would the etchant-cooling be enough?
