Greetings Dan, Excellent preface to your project and a damn good history lesson. I was very young at the time, but I remember the sinking. Being from the northeast, her sinking was a big deal for a long time. I am looking forward to seeing how you do with her. Nice to see a build without masts and guns for a change. wq3296

Greetings Sherri, Elegant work on your San Felipe. However your Spanish version was built in the late 1670s - too late to have been in the Spanish Armada (1588). There was a San Felipe de Portugal, galleon, in the Armada. In addition, the Portuguese had another San Felipe in service about the time of the Armada - she was a carrack, which was a merchant ship. See book entitled The Armada by Garrett Mattingly. Others may have brought this to your attention, but your site is so popular that I couldn't read all the posts. wq3296

Question about stoves and how the rotisserie worked
wq3296 replied to Modeler12's topic in Nautical/Naval History
Greetings Buick... By all means - a venturi is nothing more than a specifically shaped constriction in a duct, pipe, etc. that reduces the cross sectional area. Accordingly, the velocity of any gas or liquid of a given volume will increase as it passes through a venturi. This is why a carburetor works. Basically, the venturies in the carb take atmospheric pressure and increases its velocity to draw fuel into the air stream before entering the engine's intake system. Properly designed fireplaces and stoves incorporate exhaust gas velocity enhancement features. wq3296 -
Question about stoves and how the rotisserie worked
wq3296 replied to Modeler12's topic in Nautical/Naval History
Greetings Druxey, Yes, I have seen the same thing. My wife bought one for the kids. Perfect example of heated gas performing work. Physics in action. There is no question that the fan system would have worked. I expect that some design went into this system, since the science was already known - otherwise it never would have been tried in the first place. wq3296 -
Question about stoves and how the rotisserie worked

Greetings Mod, No, turbochargers don't run on lots of hot air. They take in hot gases produced by combustion which have expanded to many times their original volume as a result of combustion heat. Accordingly, because of this increase in volume the velocity of the of the heated gas increases per unit area of the ducting. In other words, a heated gas flowing through a fixed orifice will have a greater velocity than the same gas at ambient temperature because it occupies a larger volume. See gas laws in any physics book. The hot gases produced by the fuel burning in the combustion chamber of the oven, if hot enough, would have been sufficient to perform work i.e. turning the fan in the flue. The reason why firemen chop holes in a roof during a fire is to release combustion gas caused buy the fire before it reaches sufficient pressure to blow the windows out or the roof off. Given the amount of evidence to the contrary, you need to rethink your position. wq3296 -

Greetings Mod... Relative to the fan operated by hot air: ever hear of a turbocharger? Your car or truck may have one. They were also used on some piston driven aircraft in WWII. The operating principal for a turbocharged engine is that the hot exhaust gas resulting from internal combustion is routed via ducting to the turbocharger. The hot exhaust gas spins a turbine wheel (fan if you will) located on the inlet side of the turbo. There is a compressor wheel attached to the turbine wheel via a shaft that spins when the inlet turbine wheel spins. This wheel compresses fresh air taken into the turbo which is ducted to the engine's intact manifold under pressure. Of course, there is more to this, but it should prove to you that hot air properly directed is easily capable of performing work. Finally, thrust from a jet engine is produced from combustion heat spinning a turbine. wq3296 -
Greetings Cap... Yes - keep in mind that the hole in the spar should ALWAYS be parallel to the face of the block. The advantage of the hole is that it allows you to pull the block up tight to the spar. Just before the block is cinched up, a small drop of CA glue on the knot will ensure that stays put. The hole may be a compromise, but at the small scale we usually work at it is acceptable to me. Let's face it, by the time you make up the block as they may have done on the actual ship, the lashings are so far out of scale that the whole assembly looks FUBAR. wq3296

Greetings Cap... See Dan's note #1. He says to pass EACH part of the strop around the spar. This is the same as I am saying, only AFTER you pass the two parts of the strop through the hole. The small knot at the top of the block to form the strop is unavoidable, and can be glued over the hole after the strop parts are passed for one turn easch around the spar, thereby fixing the block to the spar. Hey, it works for me. wq3296
-
Greetings Folks, Depending on scale I drill a small hole through the middle of the spar parallel to the way the block will sit. Then, I run the strop (i.e. thread tied around the block) through the hole in the spar and make one full wrap on each side of the block, glue the end down and trim it flush. The block will lay tight to the spar and the hole is hidden. Much easier and a lot less drama. wq3296

Greetings Chuck, You've thrown away 7 models because you couldn't get the planking right - 7 models? It sounds to me as though ships with hull planking is not right for you. Stick with solid hull models or plastic. wq3296

Greetings jbs... Logical. Thanks wq3296

Greetings, The Victory's main stay is said to be 19" in circumference - approx. 6" dia. for those keeping score at home. I expect this was one of the larger main stays ever used, but am curious to know the size of the largest main stay, cable, hawser, etc. ever used on a sailing ship. You never know - this question might come up on Jeopardy. wq3296

Greetings Bear, I have used scrapers on hull planking for years. They really remove wood quickly prior to sanding. I use shards of glass for scraping. I had some old window panes around which I broke into shards. As a result I have a lifetime supply of differently shaped scrapers that hold an edge forever. wq3296

Fastening of the false keel

...from the novel Atlas Shrugged. Whenever someone didn't know the answer to a question they would say Who is John Galt? Same as answering How high is up? wq3296 -

Greetings mrm... There should be no problems making this twist. The need to twist planks to make them conform to the shape of the hull is quite common. I assume the planking is basswood? All you need to do is soak the basswood strips in water until they are pliable enough to be worked into the shape you need. Usually, I twist them a little by eye before trying them on the hull. Typically, a soak in water of 20 to 30 minutes is all you need get the planks pliable enough for that application. I don't bother with all the voodoo and drama some folks use to bend hull planking such as heating in a microwave, soaking in ammonia/water or soaking in water for days. A little soak time in plain water is a ll you need for basswood. wq3296

Greetings Daniel, I would agree with with Mark. Plus, the 1mm represents the rough thickness at the time the plank is placed. After sanding, the actual finish thickness will be somewhat less than 1mm. Don't over think. wq3296
-
Greetings, Just an opinion, but I can't see how you get a single plank over 30', let alone 40' to 60'. To get a plank even 30' would require hauling tree trunks around that were at least that long. I can't see the need for such long deck planks, so why would they bother? It seems that it would have been much easier to handle shorter lengths. Yes, long timber lengths would be advantageous for spars and main structural members, but deck planking? Were such large trees readily available back then? Again, just an opinion based common sense, but I am willing to reconsider. wq3296

Greetings, Agree with vossy and mtaylor. The paper method reads too dark for practically any scale and becomes the "tail wagging the dog". In my opinion, a subtle dark line between planks looks best and compliments the deck and other details rather than competing with them for visual dominance. I have the same opinion about simulating deck fasteners: they always end up way out of scale and dominate the landscape. wq3296

Greetings John, Based on the outcome of this model, I'd say you are ready for the big leagues. I like Constructo kits and have built two: Yacht America and Enterprise. I have there kit of Pilar, Hemingway's fishing boat which I will build next. Constructo kits are generally less expensive than other European kits and, therefore, require more effort to finish up into an outstanding model. However, they provide a solid platform for a really good build if you put the effort in. wq3296

Greetings Jim, Very nice work. May I suggest that the foot ropes don't look natural? Too tight and too perfectly shaped. Loosen them up and let them drape to form curves instead of sharp, precise angles. wq3296

Greetings rsch... Are you guys kidding - find a formal garden, and get a piece of dogwood? All this to make some simple heart shaped deadeyes? Why not use the smallest commercially available ones and sand them down a bit? I have some that came with a Mamoli kit and they are about 7mm - walnut. I expect somebody makes smaller sizes. wq3296

Greetings Cap'n, Very nice work. Looks like you have everything well in hand. Seeing the Rat Fink brought back memories. I had a model of the Outlaw when I was a kid. Was it tough to resist the temptation to add a couple of Big Daddy touches, such as bubble canopy or chromed Caddy engine? How about a round front end end like on the Orbitron? He was quite the designer. wq3296
