David,
I have made a few of these with pretty good results. Granted, they don’t look as good as the Martin Guy’s! I made a couple wraps around the bolt, then tacked it in a couple places up the seam. Then place it in your fitting and solder the screen to the brass fitting. Heat the fitting until the solder melts. When yo get that done, just pinch and fold the top and add a drop of solder to hold it. I don’t think it’s too critical to solder every bit of the seam as long as you have good overlap of the screen.
Stay warm.
