Finally figured out all of the components I had to graft together to mount a TER and 2 LAU-3/As on the inner pylons. The pylon itself is from the kit, but the kit LAU-7 missile rails were of course meant to have AIM-9s loaded on them, which I wasn't going to be doing. So, I found some great resin LAU-7 rails from Phase Hangar, and grafted those to the adapter brackets from the kit that I had carefully removed the kit rails from. So now I have fully-detailed missile rails that look like empty missile rails.
The TERs are Eduard Brassin which went together pretty easily. The trick was figuring out how to mount them on the kit pylon, which I did by drilling holes in the pylon that were the diameter of the diagonal dimension of the Brassin suspension lugs. Then it was just press fit with a little Gorilla super glue.
The LAU-3/As? Those were a real head-scratcher. Simple enough assembly, but the front and rear are separate pieces. The front piece was easy, since it sits in a recessed cup at the front of the tube. The back piece was major brain damage, because I was going to be mating two flat surfaces, that had to first have casting blocks cut away. Burned the first 2 sets, because those mating surfaces were anything but flat and square after cutting and sanding them. So, I got 2 more sets, and fabricated a couple different sanding jigs made of 2024T3 aluminum, and let my little Micromark powered sanding tool do the precision work. My jewelers saw played the role of the stone axe to do the brute force work beforehand to remove the casting blocks. SUCCESS! Completely square, flat, and flush joints! Then they were mounted by cutting off the molded-on suspension lugs, drilling those stumps with 0.4mm holes (made corresponding holes in the mounting points on the TER) and then glued some 0.3mm copper beams into the LAU-3s. Press fit and glued those onto the TERs and that was done.
Decaling all of the individual components took a long time to get right, but overall, that went well. I think there were over 30 decals involved. Did the corrogard leading edges on the front of the pylon too.
