    Flying Boat or Bust

    Main formers, planning area ( prismatic) based on C.A.M.S. equations. Now, got to shave some weight off it. Having fun nevertheless.

    Flying Boat or Bust

    Bulkheads taking shape. Yehaw! Who needs a Flying Lumberyard while "One cord of firewood"( Plane's nickname around here) can do the trick?

    wood shrinkage

    Well, oak is used for the center portion of parts like the stem, knees etc ( like a sandwich: ply, oak, ply). Yes it is a boat, think of a runabout with wings. I appreciate the opinions, kiln drying would not reduce the moisture content to around say 20 to 25% that fast, so, it doesn't solve the...

    wood shrinkage

    I'm cutting down a white oak, and will run it thru the Alaskan mill right away. Its green wood, lets face it, now; is there any way or technique to " dry" these out? I really want to use it on the bulkheads and nose ( stem, knee, keel braces etc) and don't want to have to wait a year for the...

    By the way Larr, the M33 engine + prop+ hub+ water had a total weight of 724 lbs or 328 kgs. Info courtesy of my Italians friends of the S.A.I. AMBROSINI S.7 project. (S.7 Project)

    Flying Boat or Bust

    Thank you again Larr, I will take the third spar into serious consideration. Meanwhile I am still trying to secure a proper engine. I calculate 7 main bulkheads on the forebody with 2 stringers per section, Yeap, that gas tank and the metal fittings will require serious rework. Talk to me about...

    Flying Boat or Bust

    you are right about that wing Larr. It will required a lots of rework. But Hull is perfect.

    Tell us what you are building!

    The most beautiful seaplane of 'em all, Savoia S.21J, the " Mean Jean", a true flying boat. To be built using 1920's technics. All wood. Still on the quest for the engine ( I would like it to be piston powered, and over 600hps) thou I've seen a turboprop with a nice and attractive tag price on...

    Flying Boat or Bust

    Larr, thank you for pointing Bazzochi's book on the Schneider racers, got me a pdf copy of it. Quite interesting. ( a curious point is: No one EVER disclaim the hull width/beam, be it of a pontoon or flying boat. The beam measurement is never there. Well we can always re calculate it but...)...

    Flying Boat or Bust

    homegrown, harvested and milled Doug Fir, ( magic made with a chainsaw and an Alaskan mill) few years drying, moisture content low nowadays. Spar to be, after cutting will bath it in Linseed oil. Yeap, I understand wood. Wish I had some okume and some mahogany too.

    Flying Boat or Bust

    Understanding the project: many people come aroujd and asks me about this plane, and to fully understand it, we will have to have a look on 5 different planes, being 1 fictional and 4 real ones. 1- Savoia S.21 The Savoia S.21 is a fictional seaplane fighter that appears in the anime film Porco...

    Where did you got that side plate of it Larr? Very good, Got a larger one? Well, hull is the simplest part of this babe. Dead ride angles, keel, step, planing angles etc. On the boat side I'm safe, on the wing side..... the story is quite different. I am currently lofting the keel (hull) to a...

    Flying Boat or Bust

    Question of the day: Can I compute FROUDE number on a concave design? Asked it on the yesterday's Aopa webinar and got no answer. (Well, they're all CfI's and pilots there, not designers/engineers, after all) Does anyone here knows about it?
