Just got my monster articulated arm system and gave it a first ride last night! Definitely will be some learning curve but already dramatically easier than hand held. My question is regarding the laser set up. His instructions show putting the dot of the laser beam directly on the tool tip. I saw a demo by Lyle Jamison where he would position the laser off the edge of the tool by a distance equivilent to his intended wall thickness. When the beam went off the edge of the piece, his wall was at the correct thickness. That seems more accurate than trying to judge the distance given the curvature of the piece. Was wondering what most people here do. Thanks in advance for the input.
