Hi Everyone,
I'm about to start casting for the first time.
Ordered a Lee (pro 4?) 20# furnace and a few of their molds a week ago. Picked up about 20# of WW from a local tire store (someone else is already picking up their lead - bummer!). About half stick on and half clip on.
Okay, I've heard the the stick on may be a different alloy (pure lead?) than the clip on, so I've sorted them - as an aside, is there a concensus of opinion if that's necessary?
Here are my main questions:
1) theses suckers are dirty! I used to work in a garage, and I don't remember the WWs ever being this greasy. Does the grease just go away during the smelting and fluxing process, or do I need to clean them?
2) Is it necessary to remove some/all of the stickum on the back of the stick on WWs?
3) Not knowing about candle wax (yeah, I should have read a few more posts here, but work's crazy and we have a 4yr old and a 6m old - I now think of 6 hours a night as a lot of sleep), I bought some of the Franklin Arsenal fluxing compound. Any reason not to use it? I assume it will work at least as well as wax, but assumptions are dangerous.
4) Besides bullets, I plan on filling some brass tubes to make some ballast weights for an RC glider. I'll cut the tubing with a tubing cutter, which will provide a slight crimp at each end, which should retain the lead inner core w/o it "soldering" itself to the brass. Aside from being sure the tube is dry, and not looking down the tube in (case it spits), are there any cautions people have about filling a 1/4" id brass tube with molten lead? I have the little Lee dipper which I plan to use for this. I will probably place the end of the tube in a tight clearance hole in a piece of wood to plug and support it. Should I be concerned about moisture in the wood? Obviously, I'll use a dry piece from the barn, not one that's been sitting out in the rain.
5) almost forgot. If anyone has casting thermometer recommendations, I'd appreciate hearing them.
Thanks in advance,
