Thanks for the moral support! It's what I like about this community of thinkers and doers that represent folks who build stuff.
I like to post the details; I like how people react to it and it's cathartic for me helping me process what's going on and giving me more ideas.
Today was a mixed bag. I actually finished the two main radar systems, shot them with some primer and put them aside someplace safe. First I got the SC antenna assembled. That required a bit of fussind and annoyance. I needed to make the base for it. It needed a hole to capture the piece of brass wire that serves as a mount for the screen. Here's how I build that pin attachment that I noted the other day.
I flatten the end of the brass wire in successive steps in the flat jaws of a vise grip. I've used this trick to make all kinds of flat/round brass transitions. I then drilled it with a 0.032" drill and soldered it to the un-bent PE platform. I left the bending of them until the soldering was done.
I tried the Kester soldering paste for these kinds of jobs and it does have an advantage in that you can lay down a thin film of it, it alredy has flux and melts at a reasonable temperature. It really stiffens the little platform and the pin is terrific for both attachment and holding the assembly while working on it in a pin vise.
I made the mistake of fastening the screen and it's fragile backing frame onto the unit before I got it mounted on the pad. I also thought that the tiny PE ring that was part of the backing had the same diameter hole as that in the top of the lattice tower. IT WAS NOT!. It was smaller and when I tried to insert the support pin into it, the back frame popped off. I J-B'd it, and should have soldered it.
I attempted to get it back on again, and then it got lost again. It's now not on it and good riddance. I left that pin long and soldered the screen directly to it. That screen ain't coming off.
I put the lower pin through the hole that was continued through the platform and then soldered it from below. Oh... and the circular platfrom came loose when the heat got to it from the soldering of the screen. And the circular rail separated from the platform too. I got it all back together, resoldered the rail to the platform and CA'd the platform to the tower. So here are both major radar installations waiting for attachment to the island.
Some of the fine detals got filled with solder, J-B and paint, but from two feet away it will work. I know... the Missouri has similar flaws.
Next up was the Mark 37 gun directors. These things gave me fits when building the Missouri and based on how it went today, they're going to give me fits again. Part of the problem is my ham fisted handling and the other is the geometry of the modeling of this somewhat delicate full-size structure. The big radar on top was supported by a rather insubtantial tubular frame. The main frame juts out at an angle and is not simply supported directly underneath, and then you have the twin parabolic reflectors and other stuff attached to them.
I went through a full set of Eduard PE and then Tom's modelworks PE before I assembled the four MK 37s on the Missouri. At least the Essex only has two.
Before starting on the PE I built the plastic bases from the kit and then created a holder for them so I can add details without them moving all over the place. The base turned out to have a diameter of almost exactly 5/16". I drilled a piece of scrap and stuck the pieces into it. There were a bunch of other blind holes in this block since it's used as a drill press block so I taped them over so little PE bits down get lost in them. Then I had the idea to add some tape turned back on itself to act as "PE Flypaper" and catch dropping PE.
Here are all the GMM bits that make up the radars for the two directors.
First the pluses. The base PE is good because GMM didn't etch the bends and reduce its strength. Not only did I bend it, but it got unbent, re-bent, bent again, etc. and didn't break. That was a good thing.
After bending I tried it on the top of the director and realized that the very small contact area didn't bode well for using CA to hold it down, but I couldn't solder to plastic. So I cut a thin piece of brass and shaped it to the same size as the director's roof and soldered it to that. It's strong! I will CA the brass plate to the director after all of the rest is built.
The PE flypaper was a non-starter and was more trouble than it was worth so I pulled it off.
I folded the GMM upper mount and then attempted to solder the little tab onto the flat part of the lower mount, and couldn't hold or get an angle that let me solder it any way I tried. It was also very flimsy and kept bending and deforming no matter how careful I was. I then turned to two left over Eduard upper mounts. These are much more detailed and realistic than the GMM, however Eduard DOES etch their bends and this comes back to bite me. I got the lower mount soldered to the frame successfully and then got the upper soldered to the lower in this hybrid deal.
I also soldered the sides of the frame so the arms wouldn't keep spreading. So far so good.
I'm not happy with the blotchy solder. That was the result of using the paste and having the plate not receptive evenly across its surface. I'll do better next time. Paint will hide some of this.
Then it was time to make the parabolic double screen. This is a Eduard part also and therefore has those etched bends. The first one I bent fell into two pieces are that bend line so I worked it as separate pieces. Then suddenly... they were gone. Somehow they both got off the t-shirt and into... what?... the floor?... not this floor, at least not in a 25 square foot area. Quantum Rift again!
So I bent the second and last set I have. This time it didn't separated into two. I decided to solder this also since it's an awful CA job. Got it all soldered, and then disaster strikes.
That joint kept breaking when doing the Mo and it broke again. This picture clearly shows the difference in sophistication between Eduard and GMM. I've got some ideas about how to fix the broken support tab by reinforcing it with a piece of solid square brass stock that will be soldered into the crotch of the joint and it won't break again. I also have Tom's Modelworks PE MK 37s and will attempt those if I can't find those lost parabolic screens.
I've taken thousands of pictures on models with my iPhone and never realized that the telephoto method of finger-pinching that's used to do telephoto normal pictures, also works at doing macro photograhy. I found it by accident today and went "Whoa! What was that? How did I do that?" I played with the phone and found that I could take dramatic ultra closeup pics like the above.
I also found that my old Missouri still had it's horn and it will now be re-purposed to be the horn for the Essex.
I'm glad I found it since I didn't really want to scratch-build this. The GMM set has a PE whistle platform. Now it has a whistle to go on it. That old ship has done noble duty giving up its pieces for better projects.
