I got excited about Richlite when I saw this post, and decided to look around for a bit of it. One of the suppliers, ecosupplycenter.com, will send you free samples, so I ordered some of their material from the Northwest series in Black Diamond color. The samples came today!
They are about 6"x6", enough to use for a test piece. I had actually asked for some of the brown as well but didn’t get any. The labeled piece is 8mm thick and the diamond-cut piece is about 3.25mm thick. It’s really nice, dense material and I can’t wait to try it out.
So, I went on their shopping site and it turns out they are having a deal right now on guitar fretboard blanks, 22" x 4" x 5/16" in Black Diamond color, for only $14.95 each (originally $74.74) or $14 each if you get a 5 pack. I ordered a couple of them. Shipping is a bit pricey ($16.21 for the two boards) but maybe it goes down per piece as you buy more.
I’m thinking this stuff will be great for award bases and similar items.
