Yes, it I know from experience it does require a fair bit of work
to make a spray etcher. Obtaining a pump and is not a problem,
nor is the cost. Most of the work is designing/building a sealed
chamber and the mechanism to move the nozzles about. But since
I've gone this far it would be silly to stop now :)
Note, I had to buy a $300 plastic welder to make these tanks,
plus go through a big learning curve working with plastics (PVC).
