My old boss told me I was sanding backwards and I got mad for a week before I tested it
Was shooting the breeze with my old lead guy Dale at his retirement party in Gary last Saturday and he asked why I still push my ROS against the rotation on rough stock. I told him that's how I learned it 12 years ago and he just laughed and said try pulling it with the grain on the finish pass sometime. Did a maple countertop for a client in Valparaiso on Sunday and pulled instead of pushed on the last two grits, and the swirl marks were basically gone off the sander. Now I'm sitting here wondering how many hours I burned fighting pigtails for no reason. Any of you run your random orbit sander backwards on purpose or am I the last guy to hear about this?
The thing nobody tells you is it's not even really about direction, it's about matching the scratch pattern from your last grit before you move up. Dale probably watched you fight those pigtails for years and just let you cook because you were too hard headed to listen. What gets me is the pressure guys run. You lean on a ROS and it stops spinning right and just orbits, which is why you get those perfect little curly cues that show up the second stain hits them. Light touch, let the paper do the work, and the pull pass on the last grit is just cleaning up what the orbit already did. Whole game changes once you stop muscling the tool.
