Correct, is something i have consider too. And acrylic is half price of
PVC by square meter, i don't need transparency. About the solvent, i am
already sick of the difficulty to get the required things where i live,
and invested on the plastic welder, seems fun and i want to try it, is
safer than methylene dichloride. I think will order the PE weld it's
still much cheaper than what i was to spend on PVC.

I am interested in the opinion about PVC vs PE. Are common choices in
chemistry setups.

I not want to build a single etching tank. It's 17 individual tanks for
now, for developing, striping, etching, and test my own direct plating
palladium chemistry, as well a very complicated copper plating setup
that doesn't require phosphorous copper anodes or anode bags, and
hopefully (to be tested) can work acceptable well without additives. And
a bunch test and dip tanks. Total wide 1.15m to fit the shelf.
