    Hadn't thought of that risk. Fortunately, the foot of our sand faced berms covers the gravel where the racks usually go. I think that serves to bury the spatter and prevent ricochets. I think we have had more stuff coming uprange from pitted steel...

    Except for the bullets (too much variation of me - I melt them down), I've done all that.

    Say, richhodg66, Did you ever get that analysis back from BNE? I'm asking because I just did a little experiment at the prodding of someone with better practical experience in metal/acid chemical reactions and discovered that tin will fizz and...

    Wow, you're right! I took a strip of touch marked pewter and suspended it in a little jar of muriatic acid (pool acid - my bottle was marked something like 32 1/2% HCl. Btw, I thank you for encouraging the experiment; the old plastic bottle was...

    And even if "sun dried" only put the scrap into an empty pot. Any moisture hidden in the scrap will cause a steam explosion if submerged in molten lead, NOT something you personally want to be within 25 yards of, and not good for the ceiling, floor,...

    Commercial cast is often (but not always) made with hardball (6% Sb, 2% Sn). COWW has been described as being made of 2-3% Sb, 0.5-1% Sn, and a trace of As, and is in the BHN range you want. If those commercial casts are hardball, mixing it 1:1 as...

    A very interesting view, thanks (though it's been posted here at least two times before).

    I know my blood lead levels went up significantly during the time I mined lead from my club's berms, which then dropped when I quit that and started using more PPE with other lead handling activities.

    Maybe I need a better sense of how big a dent or nick has to be in order affect accuracy or function as opposed to just being aesthetically displeasing. A related question is about alloy hardness, its effects on surface defects, and whether that...

    Just a comment on ringing steel targets. Absolutely no doubt they're fun. I find it very gratifying to get the instant feedback on the hit. But I did notice personally that I started relying more on the sound of the hit to know I scored rather...

    How long does it take to dissolve the tin? I've left pool acid on the surface of pewter for ten or fifteen minutes and all that happened was a very slight color change. No bubbling, pitting or dissolving that I could see, as opposed to zinc items...

    My pure tin and pewter do not bubble at all. AAMOF! I use muriatic acid to test dubious pewter items. My ingots, nuggets and pewter are not tarnished, though I suppose under the right conditions oxides could form. I do not know if oxides of tin...

    I also don't need hard boolits for my application. More to the point, like Outpost, I like to eyeball the casts to check for defects and to monitor mold temp (to much frosting tells me to slow down). I drop onto folded towels on top of a tilt...

    I do that (BNE is such an incredible boon to the casting community). Sometimes I get carried away: on occasion I have so many varied scrapped containers that I process them into 10# ingots 20 at a time from a one pot batch, then recombine the same...

    Then you'd like the shielding lead (not the containers, which need to be harder to stand up to handling) that the pharmacies sometimes also scrap. I've had it analyzed: at least 99.9% pure.

    I'm trying to imagine how to make this work best. To pour just into one cavity and have the others filled from it, I'd think the notches would have to be fairly large, allowing at least the same total flow rate as what you are pouring. If slower,...

    It might be a low yield, high effort sort of situation. The falling plate racks at my club spatter the lead radially on hits on the plates proper. The plate hinges are welded to a solid steel bottom with a deflector shield angled in front. Only...

    I have to get to it too. Here on the Left Coast it's warmer, but we're just getting past the rainy season, and of course I process outdoors. True that rain on top of the melt isn't a concern, but rain in the ingot molds certainly is. Cooler is...

    I got a saw blade now. We'll see if it warps (maybe flip it over regularly, or turn off the heat when the mold is up to temp?). Anyway, better the blade than the mold.
