I am milling some two sided logs 8 inches flat to flat. I want to build a machine to dado a 2"x2" groove across the ends with ? I am thinking maybe a set of blades like a dado set stacked on the shaft of an electric motor. I have been making the grove with my chain saw mill making about 8-10 cuts 2" deep. What type of horse power would you say is needed..(dead spruce) Also I would like to rig up some type of debarking setup. I have been using a log wizard but its slow and hard on the old back. The logs I am milling are 6-10 feet long. I was thinking of some sort of lathe like operation turning the log with a rotary head that travels along the log but following the contures, not making it perfectly round. I have about 100 logs to do. Am I nuts?
