Spent decades casting indoors with well designed vent systems. For the last few years have been casting outside with this setup. Yesterday I made the 20g metal,wind shields better seen in one pic below. They'll get sprayed white today.
The other pic is the whole shooting match plugged in and warming up. 90% of the stuff stows in the Cman box. This isn't the std higher base cabinet...it's the shorter one. I find it's the perfect height.
Love the propane accessories,sprues get dropped in CI pot.... when it gets 1/2 full,light up the single burner. Melts them quick,add to pot,and flux while mould takes a short break in the little oven. Hand held torch gets used to light the burner,but also for spout duty and spot heating moulds.
Good luck with your project.
