Fab gurus, tapping tube, help me refresh my memory

[sled_dog]

Its been a while since I dealt with drilling and tapping anything so here it goes. If I want to tap a piece of tube to accept a 3/4-16 rod end, what size should the interior of the tube be? 3/4"? I can't remember this for the life of me.

a quick flip through my fabricators pocket book, and I got 11/16"

Have you read the side of your tap? Usually it will have drill size printed on it (stamped into it).

don't have the taps, don't have a tap set, will have to borrow that stuff. I only ever use taps to clean up threads.

As stated before, 11/16".
