Along the lines of "another use", I too have used the machine too make, essentially, a custum tool.
I needed to replace the fan blades on a 1924 car. The blades are held with some dihedral, and each is custom fit to the hub. Using the measurements of each old blade, I carved 6 exact fit holding jigs to allow the blades to be cradled without moving while I drilled new holes in the new blades. Made it much easier.
I now intend to carve the rack that holds the trunk to the luggage rack, as it will be a simple, quick carve too.
So, functional carves as apposed to the magnifecent artistic stuff you guys do is also an important use for this machine.
