They still have the augers but to get it to self feed all the coal you would have to greatly reduce the capacity of the bin.Basically you would need to build a slope 40- 45 degrees from the auger to the outer walls. The auger only sticks out of the pipe about a foot so you would have to do it for all four sides Most people use 55 gallon drum instead, that's how ours is set up. The ash removal system has been discussed, it would be expensive and probably wouldn't be worth it unless you had a very large home or building that was using a lot of coal, once you got past the 15 ton range it would probably be worth the investment. It's not that it can't be done but the problems that arise trying to do it. For example if you have a 7 foot basement your coal bin is going to be quite small, you need a lot of height if you want to do that.
If you really wanted to do either of those things you really need the right house to do it in first, secondly you'd have to plan for it. You'd have to install the furnace where that type of system would work best. There was another thread something along the lines of "Ultimate System".... I didn't include the auger idea in mine but the self feeding coal system was.
