I made a very lightweight grill using three Ti bike spokes, one spoke nipple and some aluminum tubing from the hardware store. I used tubing with an ID just large enough for the three spokes to fit in and cut it into two pieces, each half the length of the short spokes. Each piece of tubing has 1/16" holes drilled on 1.5" centers, with one placed in the center of the piece all the way through. The other two are drilled into just one wall. The grill is assembled by inserting the outside spokes (or rods; the threads and head are cut off so the rods are about 3/8" shorter than the whole spoke) into the two outer holes, butting up to the opposite wall of the tubing. The center spoke (with head and threads intact) is inserted through the center holes and the nipple is screwed on to hold the whole works together. I place it on two parallel logs or rocks over a small fire or charcoal (or in a fire pan if kayaking) to cook on. To pack it I insert the spoke and rods into the tubing longitudinally, then screw on the nipple to again hold the works together. Packed size is about 1/4" dia and about 10" long. I don't know what the weight is but it is certainly very lightweight, plus the packed size is minuscule. I'm sorry I don't have any photos, so I hope this narrative is descriptive enough. I'll try to post some pics when I can.
