A little further along with the 'Pup'. And there's a lot of detail you can't see in the above. But nowhere near finished.

It's more confusing and goes further than just that. 1913 saw the 'Tabloid' which was sometimes known as the 'Scout'. 1914 saw the 'Sea Scout' for the Schneider Trophy. 1915 saw the 'Two Seater Scout'. 1916 sees the Pup, officially the 'Scout' according to most books BUT as the original drawings just call it the '80hp le Rhone' I suspect the real official designation was the '80hp le Rhone Scout'. It appears that it was only after service personnel started calling it the Pup that Sopwith actually started really naming their aircraft.

A friend of Dad's had one of those, you still have to make the first one though.

When you stop learning, you're dead. Sun went down about an hour ago, it's now 10.7°C which is a little warmer than it's been at this time most nights recently. It's either been a cold (for Melbourne) winter or I'm just feeling it more.

G'day Tim, I hadn't seen it before. I'm guessing 3/4 scale with about twice the hp Alberto had. I've been playing with something else: That's a 80hp Le Rhone 9c rotary (that means the whole engine spins around the crankshaft) that powered many WW1 aircraft. Such as: The Sopwith Scout (nicknamed the Pup) 1916. Or it will be when I finish. But then I think I'll modify it to a Sopwith Dove, largely a post war Pup two seater. Or at least inspired by the Pup with three more years of development. Eventually I'll make a 1/8th model of either a Pup or a Dove. Meanwhile I'm learning more about CAD, including why those last two formers on the Pup above don't look solid (I had the same problem on the Lapwing drawing). But the Prop is still kicking my backside.

I would continue as you are but glue some 400 grit sandpaper to the back of the ruler and use several light cuts.

Not much to show this time, just push rods and a bit of tidying up. I got distracted trying to draw a prop for it and that's proved to be problematic, I see a way forward but it's going to be a pain. Still outstanding on the engine are a carburettor, oil lines, cooling system and extra flanges and bolts.

On the 20, yes (brain fade) the big one behind the pilot seat is fuel. But on the 19 there should be no coolant so it looks like he's using the fuel tank as an oil cooler or he's using the oil to heat the fuel (the oil tank in front of the engine would also act as an oil cooler). The piping appears to pass through the fuel tank. I don't know if there was a problem with something like wax in early fuels but I can't imagine why you would heat your fuel to the point it starts boiling off. 😟 On the 20, you're right, it's a coolant header tank. I assume it's unpressurised so the 'conning tower' out the top is to allow steam to condense and/or water to settle or perhaps not slop out when turning?

Alberto must have owned a worm cannery, there are more worms here than in Bounty's small cutter. No worms here, just run the fuel line to a 'T' and from that to each carb, no need to turn anything around. On to the worms. I was going to say you were lucky as on the Demoiselle the carburettor was under the wing wrapped in a piece of cloth which means I can't see it to draw it. When looking for a photo I realised that was on the 19 not the 20 I'm doing. Then I noticed the fuel tank with the associated plumbing, can of worms number one, this engine is air cooled, what's the plumbing for? The oil tank looks to be at the front of the engine. On the 20, the plumbing to the fuel tank is definitely coolant (it comes from the water jackets around the cylinders) which opens can of worms number two, why would you heat the fuel to above it's boiling point? Problems raised (for me) neither the coolant hose from the tank (there must be one, right?) or the carburettor (of the 20) are shown in any photos.

Well this version is fuel injected and has no way of controlling the amount of air ingested. The fuel injection pump timing adjustment (both coarse and fine) is interesting and the untimed pump will be oil. The water pump is hiding in the housing below and all three in this case are gear driven. As far as I can see Alberto didn't use fuel injection so yours should have a couple of carburettors, but I suspect you don't have any space left.

Tim, I get it as 89-90° to the keel (leaning aft if 89°).

You can try sitting her on coloured paper to get a feel for how it looks. If you go high gloss it's going to have to be perfect, if you go satin finish it will be more forgiving. That said, I'd probably try a gloss black. Another option might be a diorama type sea (just the top of the plinth) with her floating above.
-
That's a tough question Tim, it all comes down to taste but it sounds like you're not convinced. Myself, I feel that there's too much wood and too much straight grain. I think a black marble (or faux black marble) would add elegance and contrast. Otherwise a heavily figured wood, something complex and contrasty. My tuppence anyway.

Bill, Cutters were traditionally of clinker (or lapstrake) construction. The launches, long boats, barges, pinnaces, and yawls, are carvel-built; and cutters, jolly boats, galleys, gigs, and life boats, are clincher-built. Also Cutters of a Ship, (bateaux, Fr.) are broader, deeper, and shorter than the barges and pinnaces-, they are fitter for sailing, and are commonly employed in carrying stores, provisions, passengers, etc. to and from the ship. In the structure of this sort of boats, the lower edge of every plank in the side over-lays the upper-edge of the plank below, which is called by ship-wrights clinch-work. Yawls, (canots, Fr.) are something less than cutters, nearly of the same form, and used for similar services ; they are generally rowed with six oars.
