Thanks for looking in and your great comments Mark and Carl, very much appreciated as always. The model is very intricate but it does have a certain strength and integrity when all of the components are combined.

Another update coming very soon. ThumpUp

Hello all,

Next update!

I finished adding the remaining details to the science boom. On the top of the boom between the 'Cosmic Ray Detector' and the various cameras at the end of the boom, lies the 'Plasma Observation System'. This is the shallow pyramidal item in the photos below, which I modified slightly by cutting off a couple of solidly cast brackets and replacing them with small lengths of black stretched sprue to make a more realistic supporting framework. I also added a PE brass part from the Eduard set which adds a bit more refinement:



That PE part comes as a three sided piece which you are supposed to fold into a shallow pyramid, but it isn't the same size as the plastic kit part, so I had to separate the three sides from each other and glue them on as separate plates, though the angles are also out slightly, but it shouldn't really be obvious under paint. I also had to add a small box, scratchbuilt from plastic sheet, inside the brass boom which sits beneath the 'Plasma Observation System' which meant carefully removing a small brace in one of the sections of the PE brass boom. This box is quite obvious on the real probe but was missing in the kit as it wouldn't be visible inside the solid plastic boom as supplied. The last real parts to add to this boom were a small bracket underneath the boom, just behind the 'Low Energy Charged Particle Detector' and a small piece of white plastic card to help the boom support rod in keeping things level:





Next job was to replace the two rather thick (and fragile) plastic rods that are supplied in the kit as the 'Planetary Radio Astronomy and Plasma Wave Antennae':



I cut off the fixing brackets and the small round end caps then micro-drilled them to accept lengths of floristry wire, which was more of a scale thickness and helpfully coated in a green plastic which would also help with paint adhesion later. They will be glued in place right at the end of the build:



I then assembled the various parts of the 'High Gain Antenna' dish, added the various PE brass parts supplied in the Eduard set and a couple of wires that are also supplied as PE brass but they were flat and 2D, I wanted something more realistic so used some thin fuse wire instead:





The photos below show how the Antenna dish looks when it is temporarily joined to the main 'Electronics Bus Housing'. Starting to look like a probe now!:





Then came what I thought would be the most difficult part of this build, which was bending and assembling the very long PE brass replacement for the solid plastic 'Magnetometer Boom'. In reality this boom is approximately 13 metres in length, which still makes it quite long in 1:48 scale! The very fragile PE parts were removed from their frames on the PE sheet and carefully cleaned up so that the edges could fold neatly. This boom was supplied in the sheet as two equal lengths and would have to be joined BUT with very little surface to glue them together and still maintain any kind of rigidity! I decided to use the same system that I devised for the smaller 'Science Boom' which involved gluing 0.2mm diameter brass tubing inside the corners. However I only glued the tube as a full length piece in the corner where the triangular frame has it's open edges coming together and then added shorter length in the other two corners to act as supporting rods at the central joint. When this was all glued together using thin CA glue, it was actually quite strong and fairly difficult to see the central joint! I let that set for a few minutes then very carefully twisted the boom so that one end was rotated 120 degrees along it's length as per the real thing - that was a bit of a sweaty moment! With that successfully accomplished I then added a couple of small scratchbuilt magnetometers out of white plastic card and rod, one right on the end of the boom and the other part way along it's length. The whole sequence for building this PE boom is shown in the photos below. See if you can spot the central joint in the fifth photo!:















Below are a few shots of this very long boom temporarily attached to the probe. Counting the 1cm squares on my cutting mat should give you an idea of how long this boom is!:









All of the main assemblies in the photos above are only placed together temporarily, and will next be disassembled, primed and painted before then being permanently glued back in place. I am thinking of maybe adding a few scratchbuilt cables and wires to enhance the model even further but undecided as yet. I may just leave it as it is, which is already nicely detailed.

Thanks for looking, all comments and criticisms welcomed.

Kev.

Excellent work with the etch, especially with the length of some of those pieces.

Cool Cool Cool Cool Cool

This is going to be a lot bigger than I first envisaged.
