    Larry,
     
    I can help get you started. I'm still tweaking the final hull form of Galilee, but it's the getting started that is tough with this program. I would recommend downloading the free version of the DELFTShip program and manual from here. Be sure your system meets the OpenGL requirements. Read through the interface and hull modeling sections, and then I can walk you through setting up a file, inserting the plan images, and then building up the hull. It's not intuitive by any means, but once everything is in place, the actually modeling is pretty straight forward, and produces a cool result.
     
    PM me if you want to do this via email.

    Chris, yes, the program is actually quite useful in that respect. You just set up the station spacing on the baseline to match the room and space (14 inches and 14 inches) of the original hull, and the forward and after moulded frame edges appear on the plans. The program projects the stations onto the modeled hull surface. They aren't fixed reference points that determine the hull shape or anything like that. I have a fairly accurate idea of the framing from direct measurements on the bow at the Benicia museum and the stern at Fort Mason in SF. Interestingly, Matt Turner didn't use cant frames, so the spacing problem is even easier to deal with.
     
    Druxey, by "fidelity" I meant "true to form", not necessarily structural accuracy. I'm not sure how many bulkheads you would need to avoid the inevitable flat spots between them if they are too far apart. I've carved a half-hull of Herreshoff's Gloriana using the lift method from WoodenBoat plans, so I'm comfortable with that. I could carve the moulded shape of the hull then plank on top of that. The result would be a pretty heavy model, though.

    I think by 'straightforward' Terry means that his subject (Galilee) has a typical hull form and construction for the period.  POF would certainly be the most labor-intensive method and would require either an extant framing plan or a knowledge of general framing practices used by that particular builder (Matthew Turner).  Terry, can the Delftship program create bulkhead or lift templates for you?

    Ah: thanks for the clarification, Terry. One composite method of forming the hull would be bulkheads with filler pieces between to form a solid landing for the planks. This would avoid flat spots. (see the Hohenzollern 1660 model thread by Mr. Hollum).

    thank you Nils.........now I'll give something to really laugh about {go ahead.......I did }
     
     
    another sub assembly I decided to play with,  are the ladders  {we all know how much I love to play with ladders}.   first off though........it's not in it's proper place,  but I though I show you this photo of the assembly I just made.........I just like how it looks 
     

     
    with some 1/16 square stock,  I made the ladder that will go up the side to this part.......it leads to an upper platform.  I sanded it and took the squareness away,  but I'm not really happy with the rungs.   their not as clean as I would like them to be.
     

     

     

     
    I then thought to make one like I did on the Nordkap,  using staples.   first starting with two equal length pieces of 1/16 square stock.......marking them in 5 mm segments.
     

     
    then drilling the holes and cementing in the staples
     

     
    when all was said and done.......it looked like this
     

     
    I like it.........but wasn't happy with the fact that some of the staples weren't all the same height.......as if the holes in the Formica {all around there} wasn't a dead give - a - way to what was to happen next.
     

     
    I had to keep in mind that I was using CA...........usually when I do some bone headed move like this,  I use white glue.......much easier to pry off the table.  the admiral saw me doing this earlier.......thought it was the coolest thing in the world.........she doesn't know about the outcome yet.  she liked the wooden ladder and thought I was nutz for thinking it wasn't good enough.  I think with a little tweaking on my method   I think it would work .  these are staples that fit in the mini staplers.   of all the best laid plans..........this one was too good....NOT....to show you :D

    Hi Betty, and welcome to MSW. My condolences on your loss as well.
     
    You've taken on a bit of a monster, but nothing that can't be finished with time, patience and help .
     
    It will help a lot if we can get this model identified.  Do you have the plans for it or any other information ?
