the setup by delirious1 there on ARFCOM has serious possibilities, I can take that idea and run with it ........
I see a double plate spaced 1/4" apart to keep cases upright and a pawl setup to index the cases in the flame
(think cake wheel at the carnival for a pawl setup .... but a triangular shaped wire spring loaded)
damn, now I have myself acting like Pavlov's dog .............
