Noting the gen on USN colours, does anyone know some basics on RN colours since 1945. The particular problem seems to be decks. The RN now seem to be using a medium/medium dark blueish grey. However within my memory they used a green, and friends here remember a red brown on Leanders. Anyone got anything specific - when changes happened, from what to what? Mike Cooper, Reading UK ---------------------------------------------------------------------------- 2) From: "Michael Quan" Subject: PSM #17 - USS Porter article Mike In resin one in the kit. Is this worth the $36 asking price?? The current PSM's article on the USN Porter class destroyer is quite interesting and inspiring to build a model. I have a question about an omission from the article though: What is the camouflage scheme of the Porter when she went down? Overall 5S? 5N? What about the camouflage scheme of USS McDougal on page 26? Measure 12? What measure for USS Selfridge on the same page? Thanks for your responses in advance. Mike Quan ---------------------------------------------------------------------------- 3) From: Tom Eisenhour Subject: U-511 Howdy from hot and sweaty Texas, I'm working on the Nichimo Type IX-C U-boat model which claims to represent the U-511. In 1943, after four war patrols with the Kriegsmarine, U-511 was sold to the IJN and became RO-500. The conning tower has an unusual two-level "wintergarten" with a single 20 mm AA gun on each level. At war's end, RO-500 was captured by the USN and later scuttled in the Gulf of Maizuru. Here are my questions: (1) Was this conning tower configuration a standard design or was it unique to this boat? (2) If this was a standard design used at some point by several boats, anybody got a snappy documented camouflage scheme for this model? TIA! Tom ---------------------------------------------------------------------------- 4) From: "Alan Simon" Subject: HMCS Sackville HMCS Sackville, K-181 (1939-40 Programme Flower Class Corvette) located at Canadian Naval Memorial Trust, Halifax, NS. On a recent business trip to Canada, caught "Sackville fever." Did not actually see Sackville but gathered following info for future modeling project: (1) "Saving the last 'Flower' Class Corvette - HMCS Sackville," by Thomas G. Lynch, Warship Pictorial, Warship VIII, 1984 (2) HMCS Sackville at http://www.maritime.org/hnsa-sackville.htm (3) Royal Canadian Navy Corvettes at: http://www.tuns.ca/~mccleaae/corvette.html (4) Motion picture "Corvette K-225" (1943) starring Randolph Scott as RCN captain (aired in the last year on American Movie Classics cable channel). "The Cruel Sea" (1952) starring Jack Hawkins as RNVR Captain may also be helpful. Believe the old Airfix 1/72 Flower Class Corvette is suitable for this subject. Can anyone confirm?

Phil ---------------------------------------------------------------------------- 7) From: Robert Vancel Subject: 1/350 Scale Aircraft... anyone interested? >> Ian Ruscoe, a very good friend of ours, with WEM's assistance, is building the demo model of the proposed British Trimaran "Stealth" carrier for the company concerned.. the question is this.. As he has now scratch-built the Osprey (helo), the Joint Strike Fighter, the Merlin and the Eurofighter for this purpose 1n 1/350 .. would anyone out there be interested in us doing these aircraft as kits?? All would have etched brass details. And no, don't ask us about that carrier..... my lips are sealed... except to say that it definitely resembles a Klingon Battlecruiser!!!! << *Perks up ears* Did you say Klingon Battlecruiser? Cool.

She's open for tours all summer. Plus, go visit her on the web at: http://learning.ns.sympatico.ca/sackville/ And yes, that is "Sackville" being bashed out in Morse on the homepage... It's very nicely done, with numerous pictures, and a brief "tour" of the ship as well. Mark Kwasnycia Ottawa ---------------------------------------------------------------------------- 9) From: "Foeth" Subject: Modeling realistic water. Might be boring. I have heard quite some nice theories what angle a bow wave should have. Large for a full ship, small for a slender hull, same angle as the entry point of the hull, etc. Well, studying ship hydromechanics, I feel it's time for the truth: That angle is not dependent on the hull form! A duck swimming has the same bow-wave angle as a modern destroyer. That angle is 39.5 degrees. Why is that? A ship will create a wave at the bow that will have the same speed as the ship itself. Those are the waves that you see 'departing' a ship if your standing on it and looking down. However, now it gets complicated, the energy in the wave will only travel at half that speed. Why the angle? It is easialy derived: Draw a line with 5 different points on them. That is the ship on 5 different times. Point 'one' is 'now', so no wave is sent out by the ship. On point 'two' the wave has already a short time to travel. Draw a circel with a radius, half of the distance between points 'one' and 'two' The half is because of the fact the energy is half as fast as the wave. Draw a circle twice as big on point 'three', three times as big on point 'four' , etc for point 5. There are now a series of circles, portraying the waves at 5 distinct times. But the ship projects a wave continously. This takes somewhat more time to draw a million circles. This is not neccesary. You'll notice you are now able to draw two lines tangent to all circles, both trough point 'one'. Take something to measure the angle: it should be 39.5 degrees. Or more precise: it's the arccosine of one divided by the square-root of three. Well, anyway, remember the angle of 39.5 degrees if your going to make a diorama of a moving ship. When does this angle change? Although this angle is generaly correct, there are exceptions. A planing vessel, such as a speedboat will have different angle. Also, this angle differs if the waterdepth is less than 5 times the wavelength, but this is starting to be boring. The angle is correct for a displacment ship at speed. Displacementship means that all of it's lifting force is hydrostatic pressure, no planing! If your ships Froude-number is less than 0.4, you are safe. It's also false for very small waves, but they are not interesting for ship waves, which are much (much) larger. What is the Froude-number? The froude number is a very handy number to expres a ships speed against it's length. It's easier for a longer ship to move faster. The 'hump speed' of a small ship is lower than for a larger speed. Froude gave a number which cancels out the length-issue, so you'll be able to give a better opinion of speed. It is defined as: shipspeed divided by the square root of ( 9.81 * lenght at the waterline). It doesn't matter if you use knots, km/h. yards, feet, or meters, as long as you're consistent. (That forementioned 0.4 is for meter/seconds/kilo's) That 9.81 is a number expressed in meters and seconds (Constant of gravitational acceleration) It's about comparison, not hard values. If you have a little spare time, calculate the Froude-numbers of different warships. They'll be closely related. A number as the Froudenumer is called a dimensionless constant, which are common in all kinds of physical problems. It means that it has no unity. A velocity is expressed in yards per second, or miles a second. A dimensionless constant is expressed in nothing at all. The froude number is a very handy number, used frequently by designers. I hope that wasn't all too boring. Just remember the bow angle.

The white is useful if you need to print decals where white is surrounded by other colors - likes flags and pennants. It is not useful to create draft markings or ships names, unless you are a expert with the Xacto knife and can carve out individual numbers and letters out of white decal paper. << Try the APLS MD-1000, usually for around $250.00, prints great on decal paper and it prints WHITE and METALICS. I make most of my own decals.

Ron in Victoria B C Canada ---------------------------------------------------------------------------- 12) From: Ives100@aol.com Subject: RE: Los Angeles class submarine Funny you should mention Paul Fisher.... I just returned from the annual SubCommittee Subregatta at the New London Sub Base. I spoke with Marshall Clark, the SC President, about Paul Fisher and his resin submarine line. Paul was working on a 1:200 resin model of the Nautilus (SSN-571), and was going to re-release his earlier Sturgeon, Los Angeles class and a few other subs. He is apparently difficult to get ahold of, and has moved from the Pacific Northwest to the Bay area. I will follow up on this, and post any results concerning Fisher submarine models on this bulletin board. From the few build-ups I've seen, these were superb kits and I would welcome their reissue.

Is it needed? or is it just replacing existing brass?? The frets appear to have Railings, cranes, 200mm Olerkons,a catapult, ladders and a bunch of other stuff. The one thing it does not have, which appears to be a glaring ommission is a brass cagemast to replace the filled in resin one in the kit. Is this worth the $36 asking price?? << The detail set for the Texas is identical to the set provided in the Texas kit. I added it to my product line after designing it for Viking. As far as it being worth $36.00. Well, that's for others to decide, but it's a BIG set and will outfit any '42- '45 dreadnought. You can see it on my web site.
