Hi. I designed, built and posted my AAGF coal bin on this site last year. Now, going into my second season, I wish to comment on the design and what I would do differently. If I had to do again, instead of (for the conditions at my house) lifting the coal bin 3ft off the ground, I would have used a second auger to take it into the house. My labor was free but given the cost of the footer, backhoe and block I could have bought a second auger. Then, being only about 14” of the ground, I think I would have blocked it up on chimney blocks, added capacity to the bin and angled the bottom. I would have cut a second auger down to carry the coal into the basement and then letting gravity slide the coal into the hopper. Just wanted to share my thoughts. Other than that I am pleased with the system. Thanks for checking it out. Coal is cool. Jim

Hi Folks. I have been getting a lot of questions about how the coal enters the auger. I have attached four pictures. In the first pic you can see the four holes and the closing gates. Note the rods going out the right side, these are how I open and close the holes to the auger. The second pic shows the holes in the auger tube that line up with the holes in the bottom of the bin. Pic three shows two of the holes, one closed. Pic four shows the tool to open the gates. It is a piece of hefty pipe with a chain welded to it. Hitting outward, the chain tugs the pipe and opens the gate, only about a 5” throw. If I need to close the gate I use that pipe to tap it shut. With my bin FULL, there appears to be too much weight on the auger if all four holes are open so I only open one at a time. Being able to close the holes is important if there was a problem or like in spring when I pulled the auger out to clean it for the summer. I hope this info helped. Coal is cool. Jim
