Hey Jackson,

Do you want the distance from the bottom of the threads to the start of the small radius that you blanked out, or to the edge of the 1" diam of the body of the banjo?

The distance from the threads to the diam of the banjo is .699" and that is using the diam of the threaded shank of .540" like on the print. The distance to the small .130" radius blend between the shank and the diam of the body is .633".

Hey Andre'B thanks for helping.

Jackson this is what makes this site so great.

As I told you, I am, no good at math, and I'm so glad I have cam and don't have to figure it by hand otherwise I would sure enough never get anything done!
