Yeah, the railings are one of those, "maybe I will start those later,..." things.
I did the ones around the life boat stations and established how I would do them.
Essentially hand cut the frame, glue in some mesh. Plastic weld the rails, glue in the frame and mesh. PE sounds good, but I have never gotten a good idea on how to transfer something that fine from a drawing or cad, to metal. Most people say, "Just use a laundry marker on both sides of the sheet." Yeah right,...Works on large and rough items,... LoL and then they leave me hanging.
I just noticed the "...700 parts" statement about your model. I think I have 800 on just the interior of the car deck girder work,..."What waaas I thinking,... " that's per side
Because my boat (52") is R/C, They will probably take damage every time I move the boat. A second reason it's become one of those, "maybe I will start those later,..." things. I run a small business in Portland, But it's just me. And I am just beginning to run into those laser cutting shops. I am still just a hand drafting, hand cut sort of person. So are you still in working in the field?
