Hi,
The windscreen surround is made from thin brass sheet. I cut the outer part in two peices, port and starboard. Then cut inner parts to the same external size, but slightly larger aperture so as to give a frame for the clear sheet to sit in.
I then soldered the whole lot together carefully bent the curves into it by hand, soldered pegs on the bottom to sit in holes drilled in the deck ( I HATED drilling those!), glued in the clear sheet with superglue and stuck it on the boat!
Easy? certainly not, lol took me ages!
