Soot
I clean the oil from my moulds with brake cleaner (oudoors!) and when they are clean and dry, I first lubricate the hinges and pins: the BIG tip with Lee moulds is
LUBRICATE the hinges and ridges!
I often use a Q-Tip with some anti-seize compound and smear those areas then rub them thin BEFORE smoking the moulds.
I smoke them with a butane lighter set at high flame.
The soot from a candle gives off gases when heated and it results in wrinkled bullets. Butane soot is much finer and dry.
As for wheelweights, you'll need to secure a big cast iron pot to melt them the first time.
You'll have to pick them one by one and cull out any zinc and plastic wheelweights from the batch. Zinc is very bad because it will cause the alloy to ball up and mould details will never fill in correctly. The batch will be useless.
Zinc is a light and very bright metal compared to tarnished lead and antimony alloy.
It melts at a slightly higher temperature than wheelweight alloy so,
when the temperature is raised slowly, it forms a blob you can spot and skim out before it alloys.
To remove steel clips, I use a big round magnet salvaged from a bass speaker suspended from a chain. I skim the remainder of the dross with a cheap stainless soup ladle with 1/8" holes in the bottom to let the molten metal escape but trap the dross.
I also recommend you get some Marvelux: it doesn't smoke and you can use it inside when dealing with clean and refined metal.
When your metal is free of dross and steel clips, flux and stir and do it again for a while.
When metal looks like mercury, cast small ingots using cheap 1$ store muffin sheets that you have sprayed with Motomaster graphite grease in a spray can. Costs next to nothing and makes more manageable little metal pucks.
Mark all your ingots from the same batch with a punch so you can track each batch in the event you make a bad one.
When using refined metal for your casting you can make a secondary alloy like the Lyman #2 recipe by alloying each 9 pounds of cleaned wheelweight metal to a one pound bar of 50/50 solder. Melt, flux and stir then make another batch of "muffins". Mark that metal accordingly, this will be the metal you melt for your bullet casting.
Do not forget safety: wear a face mask, face shield and a welder's apron.
Use good leather worker's gloves and pull your work shirt sleeves over the gloves cuffs to avoid an accidental splash from dribbling INSIDE the glove
Avoid dampness like the plague. If you intend washing your wheelweights before, NEVER add some more wheelweights to the molten metal: you'll get a violent steam explosion and permanent lead freckles...
Do one batch at a time and allow cooling before filling the cast iron pot to a heap and doing it again.
In the same vein, do your melting under a car port; a single raindrop from a passing cloud can paint you and the surroundings with lead droplets!
Good luck and wash your hands before even thinking getting a smoke, drinking or eating.
