I had to plane the bottom of some bedroom doors that dragged on a shag rug, but I didn’t have my portable workbench to hold the doors on edge. Needing a quick solution, I cut some notches in two empty drywall-compound buckets down to the last reinforcing ring and placed one of the doors on edge right in the notches. To hold the door tight, I inserted a flat bar between the door and one of the notches. This setup was remarkably stable, especially after I added weight to the buckets.
