The big problem is making it with no metal other than Titanium in it.
And, no Nylon, either. Nylon crumbles within minutes after exposure
to FeCl2, and all other metals but Titanium corrode at various rates.

I built an etcher entirely of Plexiglas, including the pump. It was a mess,
but it did work. The Kepro etcher I found in the trash has pretty
standard Little Giant pumps, but the shafts are Titanium. All the rest
is grey PVC.

My spray nozzle was a piece of PVC pipe with holes drilled along the side.
The Kepro machine uses one nozzle and shoots through a piece of
fiberglass window
screen.
