I would really like it if I would share this to you.
The subject is making the starboard lower yardarm of an Arleigh Burke class destroyer
What you'll need is a leftover piece of five bar railing(?), some wire, a long piece, a piece shorter than the first and 8 small pieces (brass, copper or any fine wire will do as long as it's fine depending on the scale), some sandpaper, and super glue.
First align the long and short ones (the long piece above and the short below) then use the 8 pieces of smaller wires to make those stanchions.
Then cut the remaining stubs and sand it. Then add the railing to the left side of yardarm below it. Bend the railing slightly downward (just pull the upper and lower tip like curving it)
Attach it to the back of it and there you have it!
You can make the port yardarm by just making it opposite to how the starboard one is made.
I hope this would help
