Coal bin now done except door, turned out pretty well for scraps plus an additional $35 for 7/16 OSB.
Didn't get the dump truck today so only loaded in 3,000# from the pickup. Was actually kinda easy, used the coal shute and just shoveled for a half hour or so (cleaning up the truck took longer than unloading!). So now I at least know I can get the coal myself if need be.
Now I can crank up the keystoker in the garage and work in my t-shirt.
