So. Have you ever wanted to ask me a question? Blacksmithing related, knifemaking related, personal, or anything else? Please allow me to prove my "Male Answer Syndrome" affliction!

Re: giant cow bell

if you look again, you'll see I specified pi times the diameter (2r) of the bell (assuming a roughly cylindrical bell) time 3', the specified height diameter.

Though I do note that for a rough materials estimate, for something of this size, pi=3 gets you in the ballpark, and you always add 10% or a bit more when computing a materials estimate. Personally, though, I tend to leave pi at the number of significant digits I'm measuring to, and ignore the rest of the digits.
