Wanting to know how much 2%tin is needed in wheel weights to get good flow? Not sure. How much is 2% of ten pounds on wheel weight. Lol

Temps are 750 to get good flow,but really frosty? I’d post pic but that also keeps failing. Lol
140 grains of tin per pound of lead or about 3.2 oz for 10 lbs

Well I was told 3.7 ounces but solder is 50/50. That makes it actually 7.4oz
Well let’s say I have 15.47 lbs of ww. Like I said I can’t get calculator to work. So off your head what is 2%tin to that ratio ?? Just wanted to clear that up
This is just basic arithmetic. You don't really need a fancy calculator. It is easier to convert to oz first, though.
15.47lb x 16oz/lb = 247.5 oz
2% = 0.02
2% of 247.5 = 247.5oz x 0.02 = 4.95oz
So...2% of 15.47lb is 4.95oz. Call it 5oz.
15.47lbs lead is 247.52 ounces. You want to add 2%. That is 0.02 times your lead weight in ounces
SO... 247.52 times 0.02 is 4.95 ounces of tin.
If 50/50 lead/tin, you need to double the weight to actually get the 4.95 ounces of tin required.
SO... you need 9.90 ounces of 50/50 lead/tin solder.
Of course you are adding 4.95 ounces of pure lead to the wheelweight alloy and further diluting it and your tin, although only slightly. For purposes of alloying, I disregard the lead weight in the solder and just figure the amount of tin required.
Or just cut your 50/50 into 280 grain lengths if it is wire find out how long that 280 grain piece of solder is and cut 16 that length that is close enough , you can weigh that on your powder scale drop one piece per pound in your pot as you add your lead to the pot. Like BKsaum said don't worry about the lead in the solder not enough to make a difference.
10 lbs is 160 ozs. 0.02 x 160= a titch over 3 oz. If sourcing your tin from 50/50, double the amount. Good luck.

You need MS Excel (or similar open arch spreadsheet program) to urn the alloy calc.
