Well... lots of work, but it's sure fun!
First up today was trying out the new pedestals that will support the ship when it's finished. I got these from TotalNavy.com which I found when I googled, "Model Ship Pedestals". They're turned brass and look good. For the Missouri's pedestal I bought a lamp finial at a lamp shop. It worked good except that it's an unusual thread and I had to get different hardware to hold it all together. This one's going to have big bolts going through. I'm going to reinforce the ship hull's bottom with some thicker plywood and epoxy the nuts in place to facilitate gettng it all together.
Then I got down to business of making and soldering the three legs of the tripod mast. Using the kit's tripod legs I cut pieces of solid 1/16" brass. The back legs are a slightly different length than the vertical middle leg. I needed to solder them at the proper angles. While there could be some minor adjustments, major shifts would break the solder joints.
To figure out how to do all this, I first glued the kit's styrene parts together and temporarily glued them to the ship with white glue so I could measure the geometry. I measured the spacing of the lets at the mast top and laid out my soldered piece to locate these holes. Although the legs go backwards at an angle I drilled the holes straight on the drill press since drilling angular holes is a pain. Instead, I shaped the ends of the 1/16" brass legs do they set at the proper angle.
I then soldered them with 60/40 rosin core solder which melted at a lower temp than the silver-bearing solder that I used yesterday to layer the mast top. After soldering the vertical, center leg, I used hemostats to act as heat sinks to prevent the previously soldered legs from unsoldering. Even with the RSU, when soldering to thick stuff, enough heat would soak to the others to remelt them.
After all three legs were in place I test fit the tower to the model and made minor adjustments to get the spacing dead on. One of the biggest tests of this geometry would be how well the PE lattice platform part would nestle into the tripod. So I decided it was time to dive into this very delicate PE work.
The lattice platforms consist of three parts: the outside frame which gets folded twice sicne the middle bend is actuall a flat spot with two folds, the bottom platform with back rail and the top platform with its back rail. I use a large "hold-and-fold" from the Small Tool Shop, an essential tool if you're seriously going to do any PE work.
I thought about soldering this, but frankly, it's too delicate to get any kind of soldering tool anywhere near this assembly so I used CA. At the Scale Reproductions Inc, on Tuesday, I asked Brian Bunger (one heckuva model builder in his own right) about how he handles PE so it doesn't stick to his tweezers more than the work. His secret... he uses thick CA since it cures much more slowly, allows more working time, has more innate tackiness, and won't glue to the tools as easily. I tried it, AND IT WORKS!.
Here's the lattice platform waiting for the next step. The platforms had to wedge into the "V" created by the outside lattice. So far, I'm very happy with GMM's PE. It's etched on 0.006" stock which is a bit thicker than AM-Works. And it's not breaking at the bend lines. That's critical to keeping one's modeling mental health.
Then I had to fit this into the crotch of the tripod mast. It took a bit of fittings, adjusting the legs, more fitting until finally the legs contacted the lattice platforms evenly. I had to break on leg loose and resolder it to a slightly wider stance after I reached it elastic limit.
The wedge-shape reinforcing brackets that go under the mast top, were located on the standard set of GMM PE. I bought both sets: standard Essex and Special Essex. The lattice platforms were in the special set, but the top brackets were in the standard set. I glued them on, and then decided to ACTUALLY read the instructions. There was a tiny gap cut in the upper edge of the bracket which I wondered what it was for. It was to drop on top of the main yards stays which is all part of a single PE part. So I had to rip them off. Now Murphy's Law works in reverse sometimes. You can have a terrible time getting PE to stick when you want it to. And then you have a terrible time getting PE off when you've put it on incorrectly. In this case I darn near mangled one of the brackets trying to break it loose. I was able to reasonably re-shape it after removing it.
The yard arm is an annoying, very delicate PE assembly consisting of the center piece with all the details, and two very slim PE pieces that you apply to the front and back to triple-up the yard proper and make it stronger and look better. It was very had for me to get together neatly and it continued to break loose as I was handling it. I thought about soldering it, but decided to keep wrestling with the CA.
I filed some flats on the back tripod legs so there was more glue surface to install the yard. The very fine stay glues underneath the mast top.
I then went back and re-fit the brackets and CA'd them into place. They also wrap around the legs a bit which helped provide more gluing area.
According to the photos, the ship's bell hangs underneath the upper lattice platfrom. The kit does not include the bell, but my old Missouri had two of them and I was able to scavenge one for this more. I filed the bell's top flat and CA'd it to the underside of the top platform.
Tried on on one more time on the ship to admire it. Of course I almost had a catastrophe when I grabbed it improperly, bent the yard and separated those three parts on one end and had to sweat a bit as I got it to glue it together again. For the up-scale Missouri, I shaped my own main yard out of solid brass bar and may yet do the same here if it continues to be trouble.
There's still more work to be done on this very complex assembly: I want to put some angle brackets underneath, it gets a thick edge for part of the perimeter and then railing. Lastly there's the radar mast that goes on in back. I may solder the railing and definately solder the radar mast in place (or epoxy...no CA). All of this stuff is what makes looking at these models some compelling. As Gary Kohs of Fine Art Models described, "A fine scale model's detail, keeps you looking deeper and deeper and still finding new things of interest." I want this model to do that.
