>"is the threaded rod just one piece"
One allthread piece comes out of the end of the boom then makes two 90 deg.
bends. That is threaded into a "coupling". This coupling joint is loose and
allows the boom to move forward and back without bending anything. Another
althread piece is threaded into the other end of the same coupling and then
makes a 90 deg. turn into a coupling and eye bolt attached to the deck. The
allthread that goes into the end of the boom rotates in another coupling epoxyed
into the boom. That acts as a bearing allowing the boom to rotate. The same
system is used at the other end of the boom to allow it to rotate for the main
sheet to attach.

"How do you attach the turning block that keeps the furling line aligned with
the drum?"
Small rope. I wrapped it with tape to clean it up and keep it tight.

Keep in mind that the boom, other than just rotate, also, must be free to move
forward and back. It also can swing against the boom but the ability to swing
outward and down against the deck is important in that it will be out of the way
of the cockpit. So...the height of the boom off the deck must be the same
dimension to the side deck so that it will be out of the way.

Does that make sense? If not I will try again.
