I was wondering why you would build any of the barrels to fire such exotic ammunition as arrows when you've said many times in the past that in your opinion the only war-practical type of ammunition is the micro stefan. But than I saw that you were dared by Baghead, and I could understand that not doing this would be a blow to your pride.
Speaking of Big Blast experiments, this is one I never got to work out all the bugs in:
It is a good idea, but I've had problems find the right sized o-rings and modifying the pump head to accommodate a larger o-ring. I may get back to it some time, but right now it is on the back burner.
Awesome expansion though, if I were you I would've done it by using a section of large OD pipe and placing it around the existing airtank with quite a few more holes drilled in the pre-existing airtank and maybe some kind of jerry-worked pipe fittings which would connect the two pieces loosely with plumber's goop and JB Weld to seal, but that's just my opinion. Whatever works, I suppose.
EDIT: And, I'm not trying to hijack your thread with my pump mod, if that's what it looks like. I just posted it because it is something you might want to try to cut down on the number of pumps you need.

When speaking about a swallow, always make sure you know whether it is an African or European swallow. It is very important.
