Let’s do some math

[TaylorS]

So I’ve been working out how to get the alloy I’m looking for, I came up with this:

490.6 Oz COWW alloy
16 Oz R92 from rotometals

This combo from my math gives me the following:

92.97% Pb
3.1% Sb
3.8% Sn

Does that calculate right to y’all? I stole the WW data from another post and the R92 data from roto’s website. If I remember reading right that should come out to roughly 11-16 on the hardness scale.

according to the alloy calculator found on this site, 93.2 Pb, 3.41 Sn & 3.09 Sb

I was told there would be no math.

Yeah, thats what I was told too!

It looks like your math is pretty close.

and then the devil said, "Let's add Letters to math," and Algebra was born

Why is there always math involved?

I was told there would be no math.

And you are right! Al little dab of this and a little dab of that in my casting pot gets me to my target hardness of 10-12. don't sweat the decimals!!!!!!!!

That + PC gives me perfect shooting boolits every time.

I'm staying out if this one... ;^D

Then they added imaginary numbers and weird symbols and calculus was born...

What is math? Why is there air?
Anyone who watched Bill Cosby knows that one!

Dear Math,

Grow up and solve your own problems.

In 8th grade, on my second try at passing Introduction To Algebra, the teacher told me '...you're going to use math every day in life. You need to get a handle on it.'
I was absolutely certain he was lying.

Turns out he wasn't.

I still hate him.

i never got algebra .

the shear concept of a + b = 27 does not make sense.

It’s all a metaphor

There ya go bringing political correctness into it!

But will having to do this math keep me from playing the piano?Robert

easy move, I bought a calculator that does it
