As I began to clean up flash and straighten things out I noticed a fair amount of black stuff coming off on my hands. While this washes off me just fine, I'm wondering how this is going to effect painting the ship. I was intending to use colour coats from WEM but I'm thinking that I should "wash" the metal with something and probably a bottom coat of primer would be appropriate. Has anyone with similar experiences and how can I address this without making any major mistakes? Also what would be the best adhesive for this material? Regards, Allan ---------------------------------------------------------------------------- 2) From "Jim Johnson" Subject North Carolina Questions I went to the IPMS Nationals week before last and was delighted with everything there. There were great ship models entered in the contest which served as inspiration to build some of my stockpile of ship kits. There were more ship kits for sale than any convention in recent menory. I couldn't resist and helped the vendors pay for their trip. One thing (among many) that I bought was an etched brass set for the USS North Carolina. I determined to start on the Trumpeter kit, so I pulled out the Leeward Publications/ Ship's Data No 1 profile. This raises some questions. On Page 8 are two pictures that call for some answers. The first item is more of an observation than a question. The sailors are all in whites! They are working on the ship wearing what we called white bravo when I was in the Navy. They are white long sleeved white jumpers (no neckerchief) long white pants and dixie cup hats. I can't imagine working in these. You can't put them on without getting them dirty and wrinkled, let alone working in them. The picture is probably 1941. I wonder when they were allowed to wear dungarees? The first real question concerns the spare anchor "porch" on the port side near the bow. The North Carolinas had them and the South Dakotas had them. What was their function? They have never been commented on in any reference I have seen. They disappeared early in the ships career, but when? I can find references on when each 20mm gun was installed, but these porchs disappeared without comment. What was their function? Were they just to store a third anchor? The next question concerns the paint scheme. Both pictures are on the page titled shakedown. There are no 20mm guns in sight so these pictures were taken before December 1941 since there were 40 of them installed then. This would put her in measure 2. This is an ocean gray hull, haze gray superstructure and light gray above the funnel top. The picture shows the top of the director tower is very light, but so are the main turret fronts. This can't be because of shadows. The picture is taken from the bow and clearly shows that the superstructure between the turrets and the top of the director tower is darker. The lower picture seams to show that the turrets have a lighter face than the superstructure but there is more contrast in the picture. The picture also shows the the outboard rifles on the main turrets have white (tan?) blast bags and the center rifles have black blast bags. The bottom picture seams to show that the 5" turrets are a lighter color than the superstructure, but the turrets are in the sun and the superstructure is in shadow. But when looking at the top picture, the first 5" mount on the port side is two toned. The face has the inboard third in a very dark color and the outboard two thirds is very light. The picture looks like it is black and white. None of these things conforms to published norms. If I built the ship with these abnormalities and entered it in a contest, would it be accepted? Now for the big question. I plan on building the ship in the measure 32 scheme that the kit shows and is the subject of the centerfold of the profile. The only problem is that the kit shows blue decks and the profile shows natural wood decks. I would assume that the decks were blue, but I would appreciate more input on this. Thanks Jim Johnson ---------------------------------------------------------------------------- 3) From Skyking918@aol.com Subject JAG Collective USS Virginia (was" Inclining Experiments) I just acquired a JAG Collective 1/700 kit of the USS Virginia (CGN-38), which I of course will be building as USS Texas (CGN-39) to go with my Samek USS Texas (BB-35). As most of you probably know, the JAG kits do not come with deck railings, but only ship-specific etched metal parts. So what is the recommended railing for this model? Thanks to all who replied to my inquiry about inclining experiments.

Confirmation or correction, please. Franklyn ---------------------------------------------------------------------------- 5) From "Frank Stile" Subject TUG BOAT PROBLEMS Thought these pictures were very interesting, you might want to pass them on as an "inclining example" http//koti.mbnet.fi/~soldier/towboat.htm Frank Stile, Canyon Lake, Texas ---------------------------------------------------------------------------- 6) From "Frank Bowron" Subject Re I'm in the wrong line of work.. Quote From Gary >> Check out this recent sale on e-bay. Not a bad return on your $10 kit!Unquote << He-hee. The way I work that would work out at about $1.50 an hour. I think I'll stick to aviation to pay for my food and lodgings... Cheers, Frank ---------------------------------------------------------------------------- 7) From Edwparent@aol.com Subject Inclining Experiments In order to determine the stability of a ship, which depends largely on the correct execution of its design, it is important to determine the actual transverse metacentric height of the ship by means of an "inclining experiment". This consists in heeling the ship over to various small inclinations by means of moving heavy weights across the decks and recording the amount of weight moved, the thwartship distance through which it is moved and the angle of heel in each case. The displacement is also carefully noted. In this experiment the angle of heel O' is measured by a plumb bob hanging under the main deck on the centerline of the ship along with a graduated scale further down to measure the angle. The inclination O' is in this case produced by a weight w on one side of the main deck to the other side a distance L. Letting W represent the total displacement of the ship and letting G' and B' (which are on the same vertical line coming down an extension of the plumb line) represent respectively the new centers of gravity and booyancy; then by taking moments, W x GG' = w x L and GM = GG'/tan O' =( w X L) / tanO' A number of different check readings are taken and if these all agree, the calculated value of the metacentric height may be assumed to be fairly accurate. During the experiment the ship must be entirely free from the action of any external force or forces, and there must be no "loose" weights such as water or fuel in tanks not completely filled (free surface) The longituninal metacentric height may be found similarly, and this is usually done in the case of the submerged inclining experiment of a submarine. The metacenter of a submerged body coincides with the center of bouyancy. ---------------------------------------------------------------------------- 8) From Subject Scout-Wasp Conversion With Airwaves gone some of their stuff is now being sold at http//www.hannants.co.uk/ but lacking is the 1/72 Airfix Westland Scout to Naval Wasp (HAS 1)kit Airwaves used to do (SC72-68). Does anyone know where this still might be stocked? Hannants do a detail kit - mainly cockpit, and the canopy, but not the main kit. ---------------------------------------------------------------------------- Check out the SMML site for the List Rules, Reviews, Articles, Backissues, Member's models & Reference Pictures at http//smmlonline.com ---------------------------------------------------------------------------- End of Volume
