i use crayons for fluxing. get the kids a new box and take all of their broken ones. if you don't have kids, trade with the nursury at your church. i use a hammer handle without the hammer for opening and closing the mold. they are usually made of hickory or ash and will last for years. i second the small fan and add a large fan by a window or door to exhaust/suck the fumes out of the room. this is really a big deal after fluxing. a fork works well to retrieve the steel clips from wheelweights. i like the 10# kitchen scales for weighing wheelweights and lynotyle to get the correct ratio. ABSOLUTELY WEAR SOME SORTA EYE PROTECTION!!! do not wear nylon or polyester clothing while casting. a blob of lead will melt it and make a nasty burn on your hide. wheelweights are usually plenty hard for .45acp. in the 200 gr.+ range. if you shoot .357mag., 9MM, or anything else that is kinda speedy, you will need to alloy with lynotyle or tin or something to harden up the wheelweights.
above all, have fun but pay attention and be very carefull. molten lead is crowding 900 degrees. do not leave the lee pot unattended while heating up. if the valve leaks, and it very well may, you may end up with molten lead everywhere.
