It's wooden. I manufactured a piece to go in the gap. It's about 4" long and maybe 1/2" wide. The hard part was figuring out how to router a curve for the corners without a router. The ribbed crossmember has me stumped. I'll have to hit the craft stores and look for something close, or just leave it off, but I'm taking this thread into cabinet restoration, now, so I'd better let it go. Here is the cabinet the way I got it. I plan on putting a darker tone around the edge of the top and on the bottom, so I think I'll match the darker tone around the dial and push buttons. Finding knobs and push buttons is going to be difficult.
