Still gathering stuff and will be starting to cast soon.
Some of this is kind of confusing so please bear with me.
Alloying/WW melting in the big pot:
When you get your melt going and up to temp, you flux right? Stirring your flux in and scraping the sides and bottom. Do you skim the dross and flux off and then pour into the ingot molds?
Pouring into molds:
Assuming that you are using clean ingots, you still flux right? I've read of leaving the flux on top to hold the heat in and keep from losing the tin. If that's the case, how do you dip your ladle in and scoop without picking up the crud on top?
I went ahead and ordered a Lee 4-20 bottom pour thinking this would be easier than ladeling but if I am doing a small batch, I might just ladel out of the melting pot.
Any hep would be appreciated.
