Pictures below:
I build xylophone tables and chests in a small woodshop where my table saw resides in the only location eager for long boards. I have devised a flip table that allows the planer to occupy that space, maintain a large anti-snipe troat insert, take only a moment to set-up, and as a bonus, swivel around to receive the second pass of a large unit of lumber, without moving the wood back to the inital location.
Where the outfeed table connects with the table saw, (either contractors, or cabinet) a 2x4 runs the length of the table saw's rear edge such that the 1" thick hinged table that rests on it is at the proper height. The outfeed table is split in half length-wise and fixed with a pair of double action hinges to keep the surface free of protruding hinges. A circle of 3/4" plywood is cut large enough to mount the planer using some "L" brackets and sheet metal screws. A beefy countersunk bolt with 2" washers acts as the pivot/hanging mount for the swivel. Lastly, the legs are first cut to length by sighting down the table and screwing all but the leg attached to the flipping part, which is held in place by a upward protruding pin inserted in a hole in the table. (I prop the planer up with a stick as I only used 3/4" plywood)
With some modification, this table could flip both ways, holding yet another tool, say, a drum sander, or a jointer.
