Dale53:
I made my own version of your die rack. Great idea! I picked up a 1X4 length of Poplar, drilled 1/2 inch holes 6" on center, and glued in 3-1/2 inch lengths of 1/2 inch dowel. I cut sleeves out of 1/2 inch PVC, about 1-1/4 inch long to keep the pins off the board. It's not a "finished" looking as yours yet, but it is a work in progress.
Thanks for the idea.
