Who makes custom sized BB & granite slabs?

Here is a link for butcher block in 1 3/8", 1 7/8", 2 3/8" and 2 7/8" thick. Available in a wide variety of widths and lengths. I think they may even cut to dimension on request.

Here is where I bought 1 1/2" butcher block for my audio rack. They have an outlet about a mile from my home.

Good luck.

Perfectionist, Good luck. Please be sure to let us know how it works out and what configurations you try. I am thinking of slabbing my speakers.
