Yeah, I've smoked them. That helps for the next drop or two, then it no longer works for me. It just makes the bullets drop slightly smaller. The only difference I've seen from smoking the die is you can cast at slightly lower temp without wrinkles. I no longer smoke my dies, and all my molds drop just as fine as before. It's just my 55 grain mold that has two bullets that stick.
What I really need is to get another pot to pre-melt my lead, so I don't have to wait for my big pot to heat up again after adding sprues, bad bullets and fresh ingots.
What I do is drop the sprue right in the pot, before it cools down. I don't collect them separately and then add a whole bunch of cool sprue to the pot. Esp with my Bator mold. The sprue is bigger than the bullets. Collecting the sprue from this 6 cavity mold would be wreaking havoc on my pot level!
And my biggest problem is that my bottom spout is sometimes dribbles.
1. There's an adjustment screw on the top. Make sure that it's set to allow the rod to lower completely.
2. Keep a flathead screwdriver by the bench. When it starts to dribble, turn the actual rod (not the adjustment screw) back and forth a few times while putting downward pressure on it. That's why the rod has a slotted top.
3. Every now and then you may have to clean out a clogged spout. Completely empty the pot. Flux, stir, and pour out most of the pot into ingots, then turn it over and dump out the remaining lead into the ingot mold. Then you can take out the rod and clean off the dross. To get the rod out, you can unscrew the adjustment screw near all the way, then just slide the rod by it. You can completely remove the whole shebang by unscrewing the lag bolts on top and bottom of the handle mechanism. You can heat up the pot with the rod removed and clean out the spout with a drill bit. A 5/64th's is a perfect fit, and with the pot heated and empty, you can just stick it through the bottom of the spout and spin it with your fingers. (If you're daring, you can do this with leather gloves or pliers while the pot is full, but it's hella hard to spin the little bit with gloves on!) Clean the top of the hole with a Q-tip. Then chuck up the rod in a drill, put some lapping compound on it, and spin it in the hole to clean off any gunk on the part that forms the seal and to ensure a good fit.
BTW, to clean off any dross stuck on the pot, I use stainless steel wool gripped in a pair of forceps. I dip the wool in a tray with a dash of diluted muriatic, and this dissolves most of the metal oxides stuck on the sides. (Many metal oxides look like dirt/rock and readily dissolve in acidic solutions. I. e., diluted muriatic will dissolve most of the crud left in the pot.) Then I wipe it down real good with some cloth patches in the forceps, dipped in water. This can fairly quickly get the pot close to like-new condition! Just wear rubber gloves, do this outside, and keep your face away from the pot for the fumes. And if you're not going to use it for awhile and you live in a humid environment, you might want to wipe it down with a baking soda solution to neutralize the residual acid salts leftover, or even wipe it down with an oily patch. The lee pot is stainless, but contact with muriatic has a way of leading to corrosion. Just remember to fire it up outside, the first time, if you use any oil.
