:redneck:I have a lot of pure lead on hand and this will be the first time making Lyman #2 without wheelweights. I purchased a few 1lb. ingots of 70/30 - lead/antimony & a few 1lb. ingots of 50/50 lead tin. What I've came up with this is 7 lbs. pure lead + 1 lb. 15oz. of 70/30 lead/antimony & 1 lb. of 50/50 lead/tin.
Had to scratch my head a little. Does this figure right? Comments wanted!

sounds about right . I get that roughly figures to 5% antimony 5% tin.

Thank you muchly![smilie=s:

If you run out of that alloy and have access to or want to buy some Linotype, a 50/50 mix of it and lead will yield a Lyman #2 equivalent...depending on the hardness of the Linotype as I've seen it run from BHN18-22..

Your figures will yield an alloy that is 5.85% Sb and 5.03% Sn.

If you want to get the Sb and Sn closer to being equal (not that I think it would matter that much...) cut back the 70/30 from 31 ounces to 27 ounces and raise the pure lead to 7 and 5/16 pounds. Leave the 50/50 at one pound.
That will give 10 lbs of Lyman #2.

I believe, my friend that you have just split the proverbial "hair". Thank you.:coffee:

I have an alloy calculator in excel here:

Here's another way to get close to Lyman #2:
7.5 lbs pure + 1.5 lbs Superhard + 1 lb 50/50 solder = alloy with 5% tin, 4.5% antimony

btw, 70/30 lead-antimony is commonly called "Superhard"
