OT CNC Termites? Was Grizzly G8689 mini-mill CNC retrofit kit

John,
You often see Tree mills being towed behind nursury trucks. You put a
tree in one end and sawdust and chips come out the other. This
process proved too complex for some of the tree mill clients so they
produced a short run of automted tree mills that were capable of
devouring a Tree on the hoof. These machines required very accurate
controls and feeds and were implemented using ball screws and servos.
Unfortunately by the time the machine was finished it was too heavy
for road usage. Pictures available at:
