8bore,

I just checked it again, with my dial indicators, and it shows 3.505, that's 3 1/2" + .005. When I first checked it, I thought it to be a little obtuse, but I am giving you what the dial indicator says. The needle is showing .005 past the little 5 after the 3" mark on the sliding scale. Now, if I am in error, please correct my ignorance!

humbly I am,
binko
