Discovered why my chipper wasn't working 100%, for that, see http://www.youtube.com/watch?v=gGTUVbL4J-8
Dummy me had installed one of the chipper blades backwards. So I took the opportunity to take out the blades, touch them up on the stone and re-install.
Here is another video I did on disassembling the hammermill to take off the serrated knives. https://www.youtube.com/watch?v=Kpi8v5wGL9M
UPDATE 2019 Mar 24 - New video on hammer mill blades sharpening and removal of parts. https://youtu.be/G0xwpBSzhlQ
