The auger is a Hutchinson. It was $420 picked up at a somewhat local grain company. That is what I would have cost to get a jet or Westfield shipped here. The motor is from harbor freight, $100. Fills the hopper in about 30 sec. I just cemented a 6" piece of pvc pipe through the wall and slipped the auger through it. I'll try to get a video of it working posted but I can't even figure out how to rotate the pics right.
Last year I had 3 bins out in the garage it was a pain to bring the buckets through the house everyday. So over the summer I built one in the basement. I don't have any of me building the bin just the bin done, and in use. I still have to finish putting the paneling up yet. Next year I want to redo the front and use better wood to hold the coal back and maybe put in a little slide door for easier way to get coal out. I was also thinking about putting some sort of exhaust fan to exhaust the dust outside, or cutting a hole in the wall for the shop vac hose to get rid of dust. I used silicone all along the bottom, between the sheets of wood, the corners and around top to help keep dust out. The bin is 4' wide by 6' long 5' high (front board and window)
The bulk bin for the 24 ton tractor trailer load, 15' wide 24' deep with a 4' apron and will have 4' high walls, will easily take the 24 ton, we plan on getting another load next year to top it off then we will have enough for 2 years, those are cedar 6x6's in the ground roughly 2-3'. 4" pad with wire mesh and 5" apron.
My coal bin, capacity 40 tons. My logic is a TT load is 23 tons and I will not go into winter with less than 15 tons, my usual consumption. I am getting ready, I just need a small load of buck for the ultra cold weather.
