Quick clamp for a flash
As I got the 1/4" bolts and nuts I was able to make the quick clamp for a flash. It took about a minute from start to finish and it holds the receiver+flash combination very well in place. Just a hole through the handle and fasten the bolt and it is ready. I'll have to do couple more of these because they take so little amount of space and few of them fit nicely to the camera bag.
