Thanks Doug, it's a cool block. I made it from an old furniture clamp (like a pipe clamp).... it started out about 4 feet long.
I miter cut it and turned it 90 degrees. I made the internal slots from 1/4" oak, then stained and distressed it to match. I ripped the old wood from the clamp to make the two outside pieces.... sort of a veneer.
Here are a few more shots.
