Testing operations with the commercial 12 hooked up to the mighty mac wood chipper, running my new 1/4" screen. this is all testing phases of my idea to start making my own heat fuel pellets. in order for pelleting, woody material must be processed through a 1/4" screen, and this machine seems to be doing a fine job. I now have plenty of chipped material ready for the mill, I now need to do the research and find the best mill for my needs.
