Ahab, I certainly could make a pattern. But a CNC router would be faster and more accurate. For that matter I am sure I could pour my own, but that would require acquiring and assembling everything that is needed and then the learning curve and mistakes. If I can get a few of these made for a few hundred bucks that's the way to go. I agree I don't see 3D as being a viable option. I am entreating CNC.
VV- the NFM units are my back up. Were Atkins and Hoyle at the show? If so I will locate them this weekend.
I haven't spoken to any Trumpy owners directly. The first problem is there are only six of my size Trumpy in existence. Under sixty feet. My boat is small for a Trumpy so most hardware is considerably larger than what I have. The next problem is Trumpy owners in general are very private. We don't have a club per se where you can get a persons name and contact info or even a forum I can ask questions. I have been in touch with Jim Moore's who is sort of the ring leader of our little circus. He has his ear out, reaching out to the owners and looking around. He did turn me on to the boat in the photos attached. This boat below burnt last Christmas eve. I went to see if I could salvage the windows before they cut her up. Unfortunately they were to big. I am fairly certain the windows were cast at Trumpy so I can't even look at other vintage lights and just use the door. I have also posted on the wooden boat forum hoping to get an answer over there.
