I've thougth several times about building a lift to at least get the wood to the door, but I think it might be too difficult to get it stacked inside the stove. My stove is near my garage, so I have a good air supply for a pneumatic lift, or even a small electric winch would work well. I have 4 ruptured discs, and a titanium plate in my neck, so I have to split my wood fairly small to be able to get it in. A 6" round 24" long is about my max. A 12" round gets split into 4 pieces.
I did see one once with a very wide door, that looked like a pallet burner. The guy loaded the wood in rounds with his tractor onto 2 old railroad tracks elevated in front of the door. He had "dogs" operated by levers that allowed the wood to roll down the tracks once he threw the lever, and another lever that stopped the next log. You are limited to using rounds only with his set-up, but it worked for him.
Any ideas?
