The drywall guy's level trick has saved me two hours a week
Last month a drywall finisher I shared a job site with in Tacoma watched me shim a face frame for the third time and said, 'You're doing this backwards. Set the cabinet, then level the floor, not the box.' He showed me how he uses a 4-foot level to find the high spot on the subfloor, scribes the base, and cuts it instead of fighting with wedges forever. I tried it on the next three units and my install time went from about 90 minutes to 25 per cabinet. Has anyone else used this method or do you still split the difference with shims?
That whole thing clicked for me after I read it. Fix the base, not the box. Same reason I check my truck tires before loading a heavy pallet. Most people just keep adding patches instead of finding what's actually crooked underneath.
