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.
Plumbing stacks may run inside the walls of your home, from the basement to the attic, with openings at each floor where the pipes branch off. Use the piping runs in the basement to help you locate holes. Plug the bottom and top of the chase with foam caulk or 6ml polyethylene.
