Adding pure Tin to WWs

[knotbrush]

I scored 2 one pound bars of pure Tin. They look like solder bars but marked "PURE TIN" from the mold. Before I chop them up I hope to find the best way to dissolve in the Tin into WWs. One thought I had was to grind them up into swarf with the Bridgeport. It would be easy to weigh out the shavings but I'd rather not do all that work. I will mix these ratios: 9 lb WW, 1/2 lb pure lead and 1/2 lb of Tin.

I think I was figuring about 2 oz of tin for 6 lbs of coww.

See if WWs fill out good enough without adding tin. If not add 1-2% until you get what you want. I add 2% to my mixes and am happy.

Tin is about $17.00 per pound. Don't use more than you have to.

That's around 5%. Too much tin! I like 1% - 2% tin with WW. I would add 1 or 2 ounces to 10 lb pot.
For your 9.5lbs, 1.5oz would be 1% tin. 3oz would be 2% tin.

You don't need to grind them. Just cut with snips, saw or whatever. You could mark them into approx 1 ounce pieces and hold them in the melt to the point you want melted off. Tin melts quickly into melted lead or WW alloy.

You could also melt the tin into little "buttons". I have heard that some people use the bottom of an aluminum can as a mold. I bought some of those stainless steel condiment cups from wal-mart for this purpose.

I weigh my WW ingots with a postal scale & then use PVC pipe cutters to very easily cut off a peice of tin and weigh that @ 2% of the ingot weight.

lucky find.

Great find. In order to make my tin more user friendly without waste; I melt the brick down and then pour it into/along a six foot length of angle iron/aluminum. That way I end up with triangle rods of about 1/4 to 3/8 inch thickness that I can easily snip with a pear of side cutters.

Congrats on your find.

Too much work. Just weigh the bars then mark off equal distances w/ a Sharpie & hold the tin in the pot until it melts to the line. Easy. So a 2# bar would divide into (8) 4oz sections. Just about right for adding to 19# of ww alloy.
