Piled coal naturaully makes a 30 degree angle by gravity. If the coal bin has a sloped floor it should be 45 degrees. Less just won't quite do it.
I did a bunch of testing because I'm about to build an indoor bin. I could go on a long time about strel floor, vrs, plastic, vrs wood, but the bottom line is make it from wood with 45 degree slopes.....or no slope at all, the coal will form it's own downward funnel, you'll just have a ton of coal that never gets used.
