As a quick guess ~ 0.020 - 0.050" smaller than the butt od in the rod specs should get you in the ballpark.

You could wrap a thread around the rod a couple of times and then mark the thread at one location. Unwrap the thread, and measure the length. To get the diameter divide the length by (pi * # of turns).

If you need better accuracy spring for a micrometer or calipers.

Hi John,could you explain what " pi* " is?

You kind of lost me on this.LOL.

To get the diameter divide the length by ?

Thanks.

In case John doesn't check his post, the mathematical value of the Greek letter "pi" is 3.1416

(Don't they teach this in 3rd grade anymore???)
:hehe:

Thanks Bob, Geometry is still taught , but I think its at the high school level. Teaching the use of the slide rule is whats gone the way of the dodo bird. I sure don't remember how to use it.

Thanks Bob.

That's what I thought John meant but the "*" after "pi" kind of made me second guess.

I wanted to make sure it wasn't "pi squared" or something ;)

Now they teach that in High School? It's part of Geometry? Not in grade school anymore? Yeah, I guess school isn't what it used to be. :rolleyes:

Boy, I guess I'm showing my age!:hehe:

you missed the first part of my post they still teach it in grade school all they taught to do with it though was to find the circumference of a circle

they use it more in high school though
