Greetings!
I wish I had more progress to share, but perhaps what progress I have to share will explain why things are moving slowly.
The carpenters have wrapped up cabinetry elsewhere in the house, and have been working in the theater. It's hard to take really good photos to show what they've been doing, but I'm going to try a few!
First, this is the casework near the entry to the theater. (The door is temporary and will be replaced -- see below). The wood is Sapele, and the corner is mitered and bookmatched (you can see the grain flow around the corner). Where the keypad will go to control the lights and power the theater on and off, you can see that the woodwork has been routed so that the keypad and its faceplate will fit flush.

The baseboard throughout the theater is also done in Sapele. While most of the walls will be treated in stretched fabric, the door and window openings and a few other spots get these Sapele treatments:

Speaking of baseboards, the step-downs onto the stage and then into the pit have all been treated with wide Sapele, including some veneers. Here's the step-down to the stage:

Here's the left edge of the pit, looking back from the stage. (The large piece of Sapele against the wall is a veneer plywood destined for one of the doors -- see below).

And, here's a shot of the curved front of the stage, looking across towards the right side of the pit. The stage itself is protected with cardboard.

I've mentioned the doors a couple of times. KYDG's specs for the doors called for a minimum mass per square foot of door. It's a lot of mass, so the result is a hell of a lot of door. Here's the first one, construction complete, ready for finish:


Just to give you a sense of scale, here's the thickness of the door!

The doors are built around a conventional solid-core door, but they have been wrapped on all sides with Sapele, including a Sapele veneer panel on the front and back, surrounded with an inlay detail. Each door will require three 4.5" ball bearing hinges, and will be gasketed on all sides.
That's it for now! More in a week or two as we have more woodwork to show!
