I build log houses and use a log wizard on every iog. When I first got one I mounted on the end of a 18" bar (shortest I had at the time) and found it very hard to control. But then my logs will become someone's wall paper and siding. For cordwood a smooth finish may not be important. I found that adjusting how far the blades stick out of the drum can make the cut much easier to control (I use a $10 harbor frate caliper to keep them even). To keep the unit as short as possible, I get 2 bars with bad tips from my saw dealer, cut the engine mount end of both and weld them together. One end on the saw and the log wizard on other with no drilling (not easy with a saw bar). I once hired someone to debark logs who thought the trigger was a light switch, all the way on or all the way off. The problem is that if the log wizard isn't using all power saw has it stop sparking (fireing) ever other time and the unburned gas built up carbon under the piston rings forcing them out until they ate the cylinder on 3 new saws, about 6 weeks each before I figured out why. You should keep speed near max but not wide open. Good luck with your cordwood house. I once a cold northern Wisconsin winter in one and stayed warm inside with a small wood stove.
