Building the OTW Type VII Conning Tower (Part 2)

10/12/05 - The anti-skid strips that surround the 88mm Flak gun were a bit tricky. I needed thin, uniformed texture strips. The texture needed to be raised and rough. After trying several items, including sand paper that was backed with CA glue, and making and impression on sand paper and casting that up in resin, I came up with an idea. I took styrene strip .010 X .060, spread CA glue on one side, and sprinkled resin dust on top. [ The resin dust is the sanding dust that accumulates when I sand down a resin piece. Instead of throwing out the dust I save it to mix with CA glue and Epoxy resin in place of micro balloons. ] The resin dust gave the strips the texture of sand paper in the right scale, and the styrene strips gave an uniform look to the anti-skid strips. I then printed out a pattern that I generated in Visio. Rubbed black charcoal on the back of the print out and turn the pattern into "carbon paper".  Traced the pattern on the hull, used my compass to draw three concentric rings, and then glued the strips down. (Sometimes I actually impress myself.)
 
The plastic figure is in 1/35 scale the small capstan is Accurate Armor, the larger is 32nd Parallel. As you can see, I didn't like the scale of the capstan that was supplied with the Accurate Armor kit. However, after a little reshaping I was a bit more satisfied with the look of the 32nd parallel one. I used the same anti-skid strips from above to surround the capstan.
The hatches that came with the kit were too flat - no dimension. So I cast up a new one, duplicated the hatch and inner bracket, made a new hinge, took a brass tube and wrapped copper wire around it, and CA glue the whole thing together. The red an white dots on top are common pins. After the hatch is painted - ah much better.
(to calculate scale I wrote a program that you can use at: SD VENTURE, click SCALE CONVERTER.) As previously mention, the jig for the brass rails was laid out and all parts solder together. Each brass rod was cut and shaped to the angle of the railing. Holes were dilled on the deck using a bench drill press. CA glue and Epoxy inside and out was used to secure the railing. I used .065 brass rod (2.08" scale) instead of .045 (1.44" scale). I figure since the boat will be handle in and out of water the little beefier brass rod would wear a bit better. If this was going to be a static display I would have used the .045 brass rod.
A small problem with scale arose. The deck is 1/32, the tower is 1/35 - that equates to  0.03125 verses 0.02857 a difference of 0.00268 - not a big deal, right? Wrong. Because the tower is slightly smaller, I had to move the railing forward about an half inch to accommodate the position of the high spot in the railings. If the tower was in scale with the railings - the tower would sit back about 1/4" to 5/16" of an inch. Thus making the railing high spot line up the conning tower. (Just keeping the perfectionist out there honest).
I'm not 100% satisfied with the bollards; however, for the time being they're adequate. It would be nice to have the bollard top as photo etched and you solder on a brass tube - I may tackle that task some other day. A small panel was placed under the bollards to show two things: that's how a reference picture had it and it looks a lot better than the bollards just sitting on the deck. The chocks are supposed to be the closed ones; however, the closed ones that were part of the kit were way to big, even for 1/32nd scale.
 
Been working on a lot of things, but it feels like I'm not getting anything done!!! Been re-scribing all the deck lines. This has been taking most of my time. Very slow process. Been cleaning up several blemishes, prime and sand, prime and sand stuff. Also scratch built an access grate.
It took me a four days to put together the 88mm deck gun. Everything! I mean everything need to be "pinned". No two piece are joined with just CA glue. A brass wire runs between every piece. I used .015 wire and a #78 drill bit to do most of the work, .032 brass rod was used in other places were a more robust connection needs to be made. Additional brass tubing purchased from PSME had to be cut and placed to ensure a solid fit. Several of the piece were duplicated for a "just incase" problem. I broke 6 drill bits drilling into this white metal. ( Click on the picture below to expand )
Afterwards the gun was painted Dunkelgrau 58.1, and "leather"; the gun was dry brushed with rust, grease, and silver to give that "used" look. ( Click on the picture below to expand )
 
I wanted the teak wood inside the conning tower to look real, many models of the conning tower wood looked too plastic and fake. To achieve this I found a package of HO 1" x 6" scale lumber at my local hobby store from Northeastern Scale Lumber. I then painted the lumber with Raw Siena with a drop of Burnt Siena. Then a wash of Oils, Black and Brown. I laid the pieces in a straight edge jig with plastic .020 square spacers. Used transparent tape to secure the bulk together. After trimming to size I use Gel CA glue to secure the planks to the inner wall. After the glue dried the tape was removed and the remainder was secured. ( Click on the picture below to expand ). I think the final results look like teak - do you think so? The picture below is taken after a clear gloss coat had been applied. The next step is to add an interior wash to the conning tower to tone down the Hellgrau 50.
Speaking of Hellgrau 50. Grabbed a tin from Randy Short at www.shipcamouflage.com, took it to an automotive paint supplier and had it turn into a automotive urethane. By the way Hellgrau 50 is the same as FS36375 (light grey on the USAF Ghost scheme), and 1994 Chrysler Ascot Gray. I thought that was kind of funny. Also note that the two pictures above were taken with the same digital camera with the same lighting - yet one looks more blue than the other. 
Just from years of use the nose of the boat was severally damaged. Here I have removed the old nose piece, built a new one, inserted the antenna anchor, and re-shaped the nose of the boat. It was then primed several times and wet sanded with 400 grit paper. Hellgrau 50 was then applied to give the ol' boat a new nose. Additionally, the conning tower deck was completed. Here you have the colors of the conning tower. The forward section painted Hellgrau 50 (same as the interior), the UZO and periscope painted Dunkelgrau 5 (same as the hull), and the hatch an 20mm stand painted Schlickgrau 58 (possibly leftover from the shipyard), and the wood floor painted Blaugrau 58.1 (the black wash on a teak deck). The contrast helps identify the individual parts, this prevents them from getting "lost' is a sea of light gray. ( Click on the picture below to expand )
Also if you notice the UZO is a little bit taller than the one picture in part one. I added about 1/4" to the UZO base to accommodate it's low statue. I found a picture of the base of an UZO, the UZO is raised a bit from the deck with sort of "toe kick" area underneath with the grab bars running up on both sides. I cast up the original, made two, took parts of one and glued them to the other, then made a casting of that one. A 30 gauge wire was added to the signal light, a Black Sharpie was used to color the cable.
 
It is not often that you get 70-degree weather at the beginning of November in New England; any way the warm weather prompted me to leap ahead a few steps and spray the final color. It is nice when you can spray outside or even open the windows up. I can touch up paint later. 
After I spayed the vertical areas with Hellgrau 50, I went back and brushed on a coat of Burnt Siena mixed with a bit of Raw Siena to the top deck, then sealed it with clear coat. This gave me my teak deck. The next day I sprayed the deck with Dunkelgrau 2. After that setup for a few hours I went back and rubbed the deck with 400 grit sand paper. As I lightly “scuffed” up the deck, the “teak” color deck showed though giving me the worn appearance I was looking for. 
I needed to establish the position of the Wintergarden railing and how it was going to sit on top of its platform. This revealed a problem. I realized my original idea wasn’t going to work. The question. How will I mount the deck to the tower and how will the deck stay secure? The front part of the deck slips into the grove in the tower – no problem there, but the rear deck lifts up and flops around. I think a long screw would work. The screw that holds the deck gun in place (via a #2-56 nut) also helps secure the tower in place. The plastic gear in the picture is actually a #4-40 nut imbedded into a resin gear – the teeth of the gear help in turning the nut. Something I over looked before when doing a test fit, the rear deck didn’t align with the tower. Dang! Son-of-biscuit. Golly gumdrops, this is a big oops.
I should be applying the final coats hear and I’m back to re-shaping the tower. Anyway, I shaved off the problem areas and built up the areas that were a little short. I placed a piece of glass on top of the Wintergarden area to give me a flat surface. Glue styrene strip around the edge and use PC-11™ epoxy putty to re-contour the area. Sand and prime, sand and prime.....
 
11/12/05 - Where to begin, there still a lot to be done yet some things are completed and need to be finalized. Case in point, the deck. I weathered the deck using and oil wash of black and brown then dry brush gray enamels for the highlights. Afterwards it was time to insert the deck into the conning tower. Now it was time for the Wintergarden. I had started assembling the rails a week or so ago and ran into several problems. The way I was doing assembly just wasn't working. I tried a few more attempts and they kept coming out looking totally retarded! They looked like a blind man with one arm was doing the work. (no disrespect to anyone fitting this description).
Thoroughly discouraged - I turned to drinking. After several vodka drinks, I had an idea. I’ll work on it tomorrow. The next day it seemed so simple, why didn’t I think about it sooner? Instead of building the railings as one piece from solid stock – build it in two pieces, upper and lower, and build it out of telescoping tubing. Then sandwich the upper and lower halves together. Duh. As I did before in my other attempts. Brass tubing was bent using my template and railing holes (.032) were marked and drilled according to my template. I used the standard K&S brass tubing with the .014 wall thickness.
I inserted .032 brass rod retaining pins at the bottom, then bent them upwards at the corresponding angle. Next I cut 11 stanchions at about 1 1/4" from .063 tubing (K&S #1251) with and ID of .035. These stanchions slip over the retaining pins. A .032 hole was  drilled though the brass tubing at the height of about 13/16" from the bottom. A drill press with a stop guide was used to help in uniform hole alignment. This hole will be used to thread wire through to hold the center rail in place. After all 11 stations had the bottom shaved at about a 30 degree angle, 90 degrees to the just drilled hole.
A .095 x .014 brass tubing (K&S # 1268) was made into a ring and drilled to accept .032 brass rod. The rod was cut to about .250 inch lengths and solder in place. The rod was then bent inward using the angle guide. The upper half was then sandwiched or slid into the brass tubing stanchions. Hey! It almost looks like a Wintergarden. My 1/35 scale tank guy says that the height is good.
Remember I have the stanchions drilled with a hole - brass tubing was bent in a circle and then cut to size - a solid copper wire threads the tubing together. After a little patients and a few choice cuss words - it worked.
A .032 hole 1/2" deep was drilled into the aft vents - this accommodates the .063 brass tubing which telescopes into the .093 brass tubing. Next a curved .093 brass tubing was cut and inserted. Because the brass tubing is telescoping all pieces went together like Plastruct piping. How cool. Remember the brass tubing inserts into more tubing which inserts into solid stock. This Wintergarden from start to finish took less than 8 hours to build. All that I need to do next is solder the joints together then file smooth.
