Top Handle grip for DSLR

Here is a simple way to build a top handle which attach to a DSLR. It close a top handle like on a Canon C300 camera. This top handle consist of a flash adapter with a pistol grip for the most basic setup, while bigger setup requires two flash adapters with a pistol grip and a flash to screw adapter. However I have to say I am not sure if every camera hotshoe can handle the stress of this setup. The parts are available at any camera shop, but be cheaper to buy each parts online via Ebay as most shops mark the prices up by allot of on Ebay they sell the parts quite cheap from China.
