For paneled doors, remove all hardware or cover it with masking tape. (If some paint inadvertently gets on metal parts, wipe it up immediately with a soft cloth.) Paint the panels, working from top to bottom. For each panel, paint the molding first followed by the interior. Finally, paint the rest of the doorl finishing with the outer edges. If the door swings out, paint the hinged edge; if the door swings in, paint the lockside edge.
When rounding out your workshop tools, consider adding two of the handiest tools used in shops of old-timers: a drawknife and a spokeshave. For the occasional job a drawknife can be used instead of the router for beveling work. It’s fast and it can make fine cuts without any chatter marks. A spokeshave is like a plane with handles, making it easy to control the depth of cut for a perfect surface.
