You can even ask yourself the qeustion whether or not
there would have been any strict planking scheme....

wq3296 got a reaction from newbuilder101 in San Felipe by newbuilder101 (Sherry) – Scale 1:96
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.

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.

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.

It is very plausible that it could work have you ever heard of a Venturi? It more like the smokestack and hood upside down the hotter the exhaust is the faster it will rush past the fan blades turning them and in turning what is ever on the end of the shaft, oh BTW if you don't know what a Venturi is it basically was on most if not all cars at one time before fuel injectors were invented so yes I very much could if not did work at one time

wq3296 got a reaction from DocBlake in 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 reacted to trippwj in Question about stoves and how the rotisserie worked
Questioning is good, Jay - how else do we learn?
Apparently the next big improvement came about in 1810, when the monopoly was toppled with the Lamb and Nicholson stove. This stove came with a much improved still that was capable of producing at least four gallons of fresh water a day. In addition, the new Lamb and Nicholson stove was advertised to use less fuel and the stove was constructed with three boilers.
I will, when time allows, see what I can find about that stove as well.

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 got a reaction from robin b in 1760's Royal Navy deck planking and waterway nibbing patterns?
Greetings bear,
Still not sure about the need for a margin plank. In your case, according to info I have prepared by Jim Roberts: "On large warships, the deck planking was tapered so that the outside planks ran parallel to and against the edge of the waterway. The extreme forward plank ends were champfered off (cut off at an angle) against the waterway plank around the bows without being nibbed into a margin plank".
If you are a newer builder, the above method will be far easier for you and, as it turns out, quite correct for your ship.

wq3296 got a reaction from robin b in 1760's Royal Navy deck planking and waterway nibbing patterns?
Greetings bear,
I agree with Chuck and druxey - no nibbing at that time. In fact no margin plank either because you would be using a waterway up against the bulwark and the planks would be fitted up to it: for this era of warship. Typically, margin planks were not used with waterways. Note that this is my understanding of nibbing, margin planks, and waterways. However, I am sure there are many fine warship models of the 18th century that show nibbing, so I am open to other opinions. I would suggest that you do what feels good.

wq3296 got a reaction from mtaylor in Do you use a scraper in shaping instead of sanding?
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 got a reaction from CaptainSteve in Bare feet on deck???
Greetings,
There are far to many variables to draw any conclusions as to who,when, where sailors wore shoes, or not. I expect that from the beginning man sought protection for his feet as the need arose resulting in the development of foot wear. As time went on convention and fashion took over and shoes became the norm even if not needed. However, the default position has always been bare feet and, unless there is a need or a requirement, people prefer to be bare footed. So what if shoes were found on the wreck? All it means is that some folks wore them all the time and others occasionally or not at all - same as today. You cannot draw any meaningful conclusions one way or the other.
Disclaimer: My opinions do not apply to any ships that may have been crewed by women. They seem to love shoes and would find a way to wear a new pair every day even if they had to work in the rigging.

wq3296 reacted to jbshan in Excess Halyard
My late friend Neb, a rigging expert, was of the opinion that the course yard halliards were belayed and much of the fall cut off. When needed, and these weren't lowered very often, the fall could be spliced back together in only a couple of minutes. If it is 100 feet to the jeer blocks, trebles, you could have a quarter of a mile of line to deal with.

wq3296 reacted to Chuck Seiler in Deck planking and how to show 'caulking'
I agree with those above that do the pencil method. For me, it provides a hint of color but is subtle. Living in San Diego I have the opportunity to see caulked deck planks on real sailing ships. Even at the distance I can get above them, which is about 6 or 8 scale inches, the caulking is not overwhelmingly dark.

wq3296 got a reaction from drake1588 in First time planking a POB hull
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.
