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.
You can cut the cost of wood glue for workshop projects significantly by buying your glue in 1-qt. or larger containers. To make it convenient to use, transfer the glue as you need it from the large bottle to your own squeeze bottles or a glue pot.
