Nice work with the rack, good thinking.
The rack with the washers work great too. You just hang all the jigs, tighten up the wing nut then flip the rack over. I have to make a new one since I got a toaster oven, other one is to big.
I've got a single curing rack like hunter's. It works well for the jigs I tie. Mine has a 5/16 threaded rod and will work with a #4 or larger sickle hook. For smaller hooks, use a smaller diameter rod.
