I've been thinking about this as well for some time. My MFT ends up sitting idle sometimes in my garage/workshop and ends up being a colectall magnet. When not in use I would like to also hang it up on the wall and get it out of the way so a car could possibly live inside. I need to be careful with lack of wall space and my desire to build cabinets to house stuff.
I was originally thinking some type of aluminum/steel c channel profile material with dimensions so that when the table is hung up, the verticle part of the profile furthest away from the wall would fit in one of the channels inside the side extrusion of the mft. But as said, slipped discs do not allow lifting of the table. While I don't have slipped discs, it likely is not going to be any better for my back either. Guess I could ask my wife to help me every time I want to do this, but it is not ideal or she is not always around to lend a hand.
I really like the idea of an arm/s that come down from the wall. Somehow line up or hook into the holes on the mft top, secure some bolts, tilt table up and lock it away. I was thinking of this last night as I lay in bed/ woke up. Is there some way two large hinges could be used along with some bolts?
I was thinking of two large hinges attached to the walls in such a way that there would be a gap between the two hinge arms large enough to place a nut and possibly a washer. One thing I would be concerned of is the bolts not being the size of the holes, having slop and over time mishaping the holes rendering them useless for their intended purpose. Is there some way some dowel or dog could be used in the process to securely position the hinges in the holes? Obviously a bolt or knob like those found on the clamping elements could be used. Once secured in place lift the outer side of the table, secure the legs up, lift the table up to the wall and secure in some fashion.
Another thing that came to mind was something I have seen used for convertible hard tops for a Miata. It would require some ceiling space though. This May in fact be easier for one person operation. Would also allow one to not use up precious wall space.

Keep the ideas coming.
