Thought I'd delve a little deeper on my process with this 8-rad pit fabrication.
Surprisingly, to me, this pit was the most challenging to build out, even though for the most part, the base is a solid casting.
The cast plate, which is used quite a few times on the Falcon, cut up in various disguises, was cut to match what I could see in the lower areas of the pit. Blink & you miss some key points on just what the ILM guys did to orientate things under the dome cutout. Took me a while to see & figure out what was going on here.
Oddly enough, the Bandai PG kit has a complete rendition of the casting plate, as per the jawboxes, which from what I can see, is clearly not what was there!. In fact, when the pit is in situ, you can't see much to the sides. The sidewalls are clearly visible in a few reference shots & theres no way the entire casting was used!. The pit sidewalls hugged much closer to the dome cutout underneath. So from my findings, most of the top part of my casting, left & right sides, were chopped!.
Styrene rod of various diameters were cut & carefully bent to shape & where pipes went down into the pit base casting plate, pre-drilled holes were made to insert the pipes for extra strength.
Me being me, I didn't like how one particular pipe sat, compared to the overhead pics of the actual miniatures, so I swapped that one out & re-sat it, much happier!.
I feel if something bothers you with a part or two, anything really, & you can change it without too much fuss now, then do it!. I find some things can nag at you for ages & can lead to regret in not changing it, that's my view, but in some cases it's just not possible to redo a part or area.
Here's the basic pit shape ready to be installed
This pipe I swapped out because...it annoyed me enough to change it!.
