Entry: Stiff corner frame Date: Thu Dec 5 12:17:35 EST 2013 I need a combination of custom rack to suspend equipment, and a support for sturdy, non-wobbly desk. Don't want to attach it to the wall yet. Thinking about triangular outer-frame design. Entry: Foldable desk Date: Sun Dec 22 00:51:36 EST 2013 A "C"-shaped support bracket with hinges |__| A heavy board that sits on top. If the support is triangled it should be left/right front/back wiggle-stable. The weight of the board on top prevents it from being knocked off. There would be some "torsion wiggle". http://hardforum.com/showthread.php?t=1676094XS https://www.google.com/search?q=2x4+desk&tbm=isch Entry: Twin-size desk Date: Sun Dec 22 02:51:30 EST 2013 I'll need to do this incrementally. Too many ideas.

Probably OK to mix the wood filler with pieces of wood to take up bulk. EDIT: PC products - 12 oz.

But why make it movable? Probably too heavy anyway. Entry: Mey's mobil structure Date: Sat Apr 13 09:56:43 EDT 2019 1. base - triangle on the floor - legs might be segmented - single stem up - suspend stem with wire This gives an elongated triangular pyramid to build on. 2. top Inside that pyramid, construct an inverted pyramid, creating a triangle at the top from which to hang the mobils. Components: A. Connectors - square section + bolts - round section + copper piping Round section is simpler to create a pyramid out of. B. Pyramid base - hooks and eyes? this would make it possible to use the maximum length of the sticks, and have both push and pull rigidity. Entry: Cubes + dowels Date: Fri Apr 26 16:21:30 EDT 2019 Works well and easy to construct. Doesn't need to be very precise. Vertical support by having barring horizontal dowels inside the cubes. Hexagonal might be a challenge. to make with current tools. Maybe triangular is better? Would be straightforward to make holes.
