well I am not planning on attaching "other" hand tools but I am planning a quick swap mount so I can use multiple spindles.
The basics for mine is 2 aluminum plates the top (or bottom your choice) of the first plate is square with the table and permanently attached to your Z. Any non removable lines (wire racetrack, air lines, Vac hose, ect) should be mounted to this plate as well. The second plate is the detachable part with the unique clamping for your particular tool. On the back of plate 2 are 2 pins pressed in square to the tool. When you go mount plate 2 to plate 1 you rest it on the pins then tighten down the screws this gives you your alignment of the spindle to the table top so it is not cockeyed. If you want to get the Y dimension in the same spot each time as well just add a third pin to the top (or bottom if you used it) so you rest plates 2 pins on plate 1 then slide it over till one of those pins are against the third pin.
Then when you want to add another tool to your collection you just have to make up another plate 2 and the appropriate clamping device for that new tool.
