Anyone here every built a spray etcher ?
I'm looking at building a spray etcher on the cheap, but I cannot
find a suitable pump. Pressure requirements are fairly high for
sprays nozzles to work effectively. The pump must be capable of
at least 10 meter head (1 bar), but all low cost fountain pumps
are rated no more than 4 meters head. Getting hold of a pump is
the killer. Example, the Iwaki MD-70RZ has 16 meter head but
sells for AU$500. The etchant I'm using won't effect stainless steel.
