I have a similar problem, including a stack of cherry in my shop aisle space to walk over, but I have nowhere near the amount of shorts that you have. At present, I have a couple of metal locker cabinets, like the ones used for women's purses, when working in factories, etc. The doors have been removed, and the shorts are stuffed into each space of them, grouped roughly by species. It is way overflowing and my scroll sawing isn't using it up as fast as it is being created. I too hate to throw any of it away, but I will soon be forced to. I have already offered much of it to my students, but even they are not taking it away fast enough. Your dividers are a great idea, but I think similar to my vertical metal lockers so I doubt the idea will help me. I hate to see it go this way, but Winter is coming, so maybe some of my neighbors will take some of it for their wood burning fireplaces. I have three plastic garbage cans outside the shop door that accumulate softwood scraps, and a friend with a wood burning furnace cleans them out often for me, but I have been keeping the hardwood shorts inside the shop for possible future use.I'll have to be sorting them soon and getting the culls out of the shop or I won't have room to work.
