Another 10 Second Flash Clamp

 This one is sturdier than the the original 10 Second Flash Clamp.  The inspiration came to me when I saw an old curtain rod laying around the house.  It has a channel which will nicely house a t-bolt, and it's also extendable.  For this 'build'  (more of an assembly) you will need a 1/4-20 x 1" t-bolt, some kind of 1/4-20 knob, and some form of "L" bracket.  You will also need some more bolts or something to mount your flash to the "L" bracket.  You can see from the picture that I make my own knobs out of plugs left over after using my hole saw, but you can buy nice knurled knobs for a buck or two at your hardware store.

Slide the t-bolt into the drapery rod's channel and place the bracket overtop.

Screw your knob onto the t-bolt and tighten it down.  If you need to move the flash up or down then loosen the knob, move, re-tighten.  Did I mention that this build takes 10 seconds?

In the final setup I fasten the rod to whatever I'm using as a light stand with a couple of plastic clamps.  I added a 1/4-20 bolt and another knob to the bracket to hold the flash/umbrellas swivel mount.  It's a pretty sturdy setup.
