So, I had some pine shelving board on hand, it was a matter of cutting it into a kit.
I had a short piece left over from another job, can't remember what... but I ripped that into three 3" x 36" lengths to serve as shelves.
then I cut a 24" piece and ripped two 4" x 24" pieces to serve as the legs. The shelf will mount over the canted 4x4 that is the leather punch block.
I will put a luan backing on it to keep things from falling thru.
I have marked the holes for the lower shelf where most of the hand tools will reside. Some will drop in, but most will slide in slots, held in place by gravity. If the idea doesn't work I'm out a bit of pine I had on hand, although it WAS a very nice piece of pine, a bit warped, but not too bad.
The "head knife" can't go into the rack though, until I make a leather cover for the blade. That's the one in the right side of the drawer with the fan shaped blade... wicked sharp. It's going to drop handle first/blade up, in the last hole on the right on that shelf. Don't want to lose any fingers.
Back at it tomorrow ...
