I like the design because it gives something nice to hold on to, and you can achieve a greater capacity without having to have a short and fat chamber.
I think that ignition at the bottom chamber gives many ignition points for the top chamber whilst also pressurising it at the same time (or there about).
This is the first or prototype design, can anyone see any real benefits or am i just dreaming

These pics are without the ignition plug/endcap.
Please comment, i want to find out why it works "so well".
