Thanks very much, ColHero. The case itself is quite a story. One day I drew a quick sketch of how I envisioned to display the shuttle...I knew I didn't want front posts right from the start. I never really though how it would all be done. In October, Brian (KNIGHTDRIVER here) came over one day to help out. He was secretly praying we would go with a simple circle front but I said, "We're going with an ellipse in front."
After convincing him to stay, we went to work making a series of templates.
The base is 3/4" MDF; one template cut out the base shape, one made to router a groove for the glass and one to cut out the top frame (which was 1/4" MDF with an identical 1/8" MDF glued on top of that for a little more thickness). The top frame also has a groove on the underside to hold the acrylic. The top glass piece I hand-cut on a table saw (with a new blade) to fit in there. Gently cleaned and perfected the curve on a belt sander.
The base has pieces added around the underside to form the lip and is patched and sanded to form a sweep. The acrylic (or plexiglass) took the curve pretty well although we did need to take 1/2" inch off the height. That small amount made it more manageable for some reason.
It was quite the process. The key is having templates that you can router around to form all the shapes.
