In midst of my office clean-up, I found the first starting gate I built (circa 2010). I know starting gates aren't all that sexy but hey, I guess it's part of Redline Derby history at this point. I just took some wood scraps I had and put them together to make a lever-release gate. It just sat on the downhill board, clipped to the back.
Funny how shitty it looks with all our 3D printed plastic stuff these days. Had to work with what you had back then! I should probably just handmake a new one...go back to basics.
