I needed a new antenna mast for my cart and bought a Manfrotto light stand. Using just the top 3 segments there was left the base. Then I found an old part of a former SKB shelf.   Here is my tripod-cart for resting my bag on it. A poor man´s version of Ed Tise´s cart.   Will see how it works when in real use. But it was fun to build it just from some leftovers anyway.   Matthias
