New to casting. I don't even have all the necessary equipment yet. I was going to start by smelting down my +/- 600 lbs of wheelweights yesterday before a light rain made me decide to pull the plug (no tinsel fairy for me, I hope)
I see most guys recommend a cast iron pot for smelting. I picked up a pretty heavy duty aluminum pressure cooker base at a second hand shop. Any reason this wouldn't work?
Also, after skimming off all of the black crud, there was a film of dull gray metal floating on top. I believe that I read somewhere that this should remain in the melt. Should I skim it or mix it back in?
This is a great site with a lot of knowledgeable folks.
Thanks in advance!
