Setting up shop part 2

Hello everyone,

Thank you for your responses to my first question about setting up a
soldering station.

My next question. Is there a particular metal I should/shouldn’t use
for creating a ventilation system? My dad and I want to make a couple
ventilation hoods to go on my work spaces but we aren’t sure what
metal to use. One hood will go above a chemical bench with acids for
etching and we want to make sure the metal for the hood won’t be
affected from the vapors.

Any help or insight is appreciated =)

Thanks,
Jen
