Well, here we go. i hope this goes well, i'll learn on the fly. End caps are almost done, I dont have a pic yet. But here's the drums, rough cut end caps, tie rods with finished nuts, and nuts before cutting the hex.

I think/hope this will work for my tube expanding, especially in the 4" mud drums.
I'm using a 1/4" drive air rachet and purchsed a 1/4" driven long socket, cut it before the hex starts so the square will fit over the wicksteed expander.

Very nice John. This is going to be neat to see.
What size tubing are you using and who are you using for a supplier? Is it 90/10 or 70/30 alloy?
