So I stumbled across this yesterday, and it seemed quite interesting:
Essentially its a mechano set on steroids, with CNC prototyping in mind (but I can see other things being built). It is based off of pegboard hole spacing, standard angle aluminum, square aluminum stock, and some (not so standard) UHMWPE channel for sliding elements. Everything else is based off of machines screws and nuts, all from the hardware store.
The main lacking area I can see is the leadscrew area with a +/- 1/32" error, although people have tried other, higher quality leadscrews (
Perhaps someone could make a good TC secondary winding rig and crank out a ton of cheap secondaries? What else do you think could be made with this stuff?

A pick and place machine for pcb assembly.
If one gets really gung-ho, one could make it bigger, and badder so that it takes very little human intervention; it would have every part it needs in a suitable magazine, apply solder paste and epoxy as necessary, place components, and then feed it off to the reflow oven.

Would be useful for CNCing larger objects, custom mounting brackets, etc. Other mechanical jigs seem like they could be prototyped pretty darn quickly if you need it.
Probably plotters, laser etchers, hot wire cutters or foam lathes seem like easy things to do with this.
