@PT-2 , Thanks for all the information. I went back looking at the pictures and in your first post in the second picture you can see the hoops. The very bottom hoop looks as though it is maybe coming apart just a little but it shows, as you have depicted, how the hoop is wrapped around itself then fastened. Near as I can count there maybe as many as eighteen hoops per mast, I'm thinking I will add this feature to my model.
These can be easily made by simply drilling out a dowel, but there is another method of using shavings from a plane which would be more realistic.
Thanks again for your time
