Craig - I know what that feels like ...  Sad Cry Embarrassed Angry
Good luck with the repair - sounds like you have a good repair plan.

There was stuff falling off that shelf that had't moved since the Reagan administration! Actually, I think I can just build and graft on a new rear fuse from a new 1/32" thick #4 former about the easiest. I got lucky on the infilled part!

Bummer... Cry Tongue maybe with a jig you could repair this damage!  Good luck in fixing this.  If worse comes to worse you could make a whole new fuselage!

LWM, when my mom was born, the Supermarine S6B was the fastest thing (short of a bullet) on Earth- and it looked the part!

Hello Craig :
     You know, there seems to be an elegant grandeur in the proportional framework symmetry in those early seaplanes.   Cool    With those two whopping floats, as big as the fuselage, they just look so powerful in their bare assembled skeletons!   Shocked   Great pics Craig!   Smiley

Thank you! The way it's rained here this summer, I might need to study waterproofing the floats!

WoW...great looking bones.  You'll have a real flyer on your hands there.  Nice job! Smiley

It's finally starting to look like an aeroplane. Time to clean up the leftover kindling and make some more Berliner-Joyce wings while I figure out what sequence I'm going to use to cover/assemble this one... As it sits there, it's a portly 57.3 grams

Thanks, Tom- That's good to know! I'm thinking maybe locking the ailerons into place, rather than hinging them. Any thoughts?

It should fly fine with the airfoil you have on the plans.  One of the reasons you see lots of flatbottomed plans here in the U.S. I believe, is because of the rules in FAC (Flying Aces Club) that require a flat bottomed airfoil.  That's just my opinion.  Symmetrical or semi-symmetrical airfoil will fly in Free Flight it just might not be as efficient.

The thing is, while it's challenging, accurate, and pleasing to the eye (things I like), it's not a very good airfoil for free flight at this scale. I think I'll peg the wings on somehow, and build another set with a flat bottom, maybe a bit... Nah, who am I kidding. Cleveland said it would fly, and even ROW. If it won't, that'll be okay.

That wing DOES have a nice elliptical airfoil and nice internal support brackets.  I'm sure you won't blow the covering ... it will be as pretty as a spotted horse in a daisy pasture.   Wink

I'm adhering rigidly to the plan- there are LOTS of places to change things around to make a better flier out of it, but if I don't blow the covering, it sure should be pretty. These wing panels are pretty chunky. 40 sq in, 7.68g.

Thanks for the link to those trimming steps- Lord knows I need it! Now if I could just get my guy to quit mowing the yard everytime it stops raining (once every three weeks or so)!

I understand the importance of dihedral & proper incidence. On the latter, this S6B is in good shape- but as I said, I have my doubts as to how good a flier it would be under the best of circumstances (heavy, small wing, no Clark "Y", etc.) so I'm leaning towards at least getting the look as right as I can instead of building a model that's not too good in either department. I'll have the plans- later I may build a new set of "flying" appendages for it.
The front float struts are attached to a fuselage former, but the rears attach to the rear wing spar at compound angles- Moving everything around and keeping the geometry right is a project I don't thing I'm going to tackle for a model that might cough up a 30 second flight.
Just the fuselage, prop, and floats -bare- go nearly 38g. It only has 80 sq in of wing. Cleveland recommended 8-12 strands of 1/8" rubber. Fly? I'm not even sure it will float! (and this will be the one that surprises me  Wink
