I love making for exactly the same reasons. I’m also planning on trying some vacuum forming, something I’ve not tried before. I scratch built my formers so looking forward to seeing if of works!
I was just going back through my reference images todays and discover there are pretty much none of that side of the nozzle. I was trying to find the number of hardware sets and saw that it was a brass hinge. New to me!
I can’t figure out how the hinge actually sticks out from the edge of the body. If I use pipe, which most builds seem to be, there’s no way that small a hinge will stick out past the wall thickness. What type material are you planning to use?
