A bit of progress this week, finding time in the evenings after things settle down a bit.
Got the hole drilled for the tree's power cord which can be run out the bottom and off the table to an extension cord. Digging around in the shop bit-box, found one of those desk cable-plugs that I can use to mask the hole a bit, then put a few screws in the top to strengthen it a bit. Easy-peezy...
So that leaves the scenic bit; we started cutting and cementing in the contours for the back side. I'm using some old USPS shipping boxes; that stuff is super-thin corrugated, super thin but strong. Cut and glued in the first three...probably 30-40 left to cut.
The opposite side (inside the curve) is a bit more complicated. I plan to include three or four small buildings over there, similar to what Lionel did on their 923 curved tunnel. Each building has the underside open so that a light can shine up into it, illuminating the windows. I think the 923 tunnel was made out of glue-soaked felt material. I can only imagine the mess that made, lol. I'm planning on using Papier-mâché, similar to the last time. This is the stuff that Elastolin used to make their tunnels.
Anyway, I don't have a good plan for exactly how I'm going to this, but I think it would be prudent to make the basic structure of the buildings first and then work on the contours which will accommodate them.
Here's a couple pics from this evening:

The first building will be putz-style representation of a hotel, the
Buena Vista. Hoping to get the basic structure of that done this weekend. I think we'll make that a lift-out so we can use it to access the battery box for the light string that'll go inside (or whatever light source we come up with). An alternative would be to just tilt the whole structure and reach up inside, but that might be awkward once the tree is in place. Still noodling this.
I'm falling back into stream-of-consciousness engineering...never a good thing
