I have some Lyman#2 (recent acquisition), (5% tin and 5% antimony, brindle approx 15). They are in 1.5lb ingots. While 15 isn’t terribly hard I still want to stretch my resource and make it 10-11 brinell. I have a lot of stick on wheel weight (which I consider “pure lead”) that are melted down into 2lb ingots. How much (in “parts” or lbs) do I need to add my stick on weight to my Lyman#2 to make my final alloy 10-11 brindle.
For what it’s worth, my pot is 25lb Lyman Pro-Mag or Mag-Pro. How ever it’s named.

Stick on wheel weights have a hardness of around 6. If the alloy you have is 15, according to my lead alloy spreadsheet, 10 lbs of your Lyman #2 and 20 lbs of stick on wheel weights will yield a Brinell hardness of 10.7

For some reason, I can no longer navigate Castboolits site. I’ve tried and tried to contact the admins and they don’t respond. |

Nice little calculator to have around.
Question- does pewter always have the copper in it?

I have a 10lb pot, and used 2lbs of #2, 1lb Tin & roughly 6lbs of that softer WW lead (pot was pretty well full to the brim at that point) and I wound up with an alloy very close to 11bnh.
I use a Cabin Tree hardness tester to get my alloy hardness #'s.
The alloy mix mentioned above seems to be more ductile and actually even more accurate than straight Lyman #2. I was quite surprised by that, with all the rave #2 is given as an all-arounder for toughness and accuracy. I'm going to stick with my house blend because of that from here on out. Personally.
You can adjust these numbers accordingly for your bigger 20lb pot. Mines just a little hobby one at 10lbs, but the hardness and mix ratio per-pound like I mention is all true to life ... done it that way, measured and fired the results and I will do many batches more
Broke the shoulder on a 3-4yr old black bear and still gave me a blood trail. That's good enough proving ground for me.
