Vulcan Boom
Based on a radial arm saw, if we have a strong boom, that can be used for a number of manual operations. This could also be constructed early and serve as the basis for a larger cnc later. With simple threaded rod and a half nut would be able to do precision movement and still be able to disengage and move quickly.
Tool Change
Would want some sort of clamping and alignment system to make this fast.
Saw
Allows for safe cross cuts.
Router
Easy rabbets.
Drill
Could serve as a basic drill press.
