T-bracket dual camera rig materials This design for a dual camera rig (see [Dual Camera Rig](/wiki/dual-camera-rig) for why you'd want to do this) is based on a T-shaped or L-shaped bracket, washers, and two bolts which fit into the camera mounting holes on most cameras. You'll need: * 2x 1/2 inch long 1/4"-20 coarse thread bolts (i bought the kind with grippy heads so i can mostly screw them in by hand, then tighten with a hex wrench) * a thick rubber washer (mine was called a "Chicago style seat washer") * 2 cameras with threaded mounting holes * a 4"x4" T-bracket with 1/4" holes (an L-bracket could work too) * a hex wrench or whatever you need to really tighten your bolts Basically follow the steps in the images below: T-bracket dual camera rig Be sure the camera is facing "down", such that it will be hung by the base of the upside-down T. I did it wrong at first.

In the subsequent image I've tilted them so they actually face down. Do this before tightening the bolts.

But if you're interested, I'll be posting soon on how to connect synchronized electronic triggers...
