DIY char grinder for biochar

You made char by the double chamber, cone pit, kiln or any other technique. The following step in biochar making is grinding char into smaller sizes. Frankly, I don't bother to do that for smaller than fist-size pieces. Many do though. Many low-cost options come to mind, passing through wood chippers, putting into bags and driving back and forth over the bags and so on. Here is a DIY project to build a machine to grind char into smaller sizes. If I know Tim a bit, he will be perfecting his invention, and this will turn into a series. Also, the "Way Out West Blow-in blog" is a must-follow youtube channel in my opinion. So please do check their other videoes.

I simply love the way the fellow kept improving the design until he got it to a working state. His narration was very enjoyable to listen to without getting frustrated at having to do it over again (in fact, I think he enjoyed having an excuse to use his plasma cutter again!)
Unless your going to be processing a whole lot of charcoal, there's a whole lot of work to build one (as he states) but it was sure fun to watch! A real tinkerer at heart....  💓

That was a pretty satisfying video to watch.  I love to see how inventive people can be.  I think I get just as good results, if not as uniform, just running over my bags of charcoal with my truck :)
