I've never done it large scale personally but there are online guides to doing it with domestic ovens and vacuum cleanersPOLAND_SPUD wrote:How do you do such things?if you vacu-form a plastic shell (like R/C car bodies) the weight will be negligible.
if you could provide a mould I'm sure a local manufacturer could do it for cheap, if not there's fibreglass as a lightweight strong option too.I believe it would be better to have one running on low pressures... your hpa setup might be ok for testing your prototypes but it would probably be a better idea to have something that can provide sustained fire
I could always buy a bigger tank
I was thinking of a semi-auto BTB QEV mod style valve coupled to a BBMG type chamber. For even better efficiency I could try to make a version of my ball valve strafer design. A decent paintball tank (remember mine is only 13 cubic inches, I can get a 48 cubic inch one relatively cheaply) at 200 bar regged down to 30 bar would last more than enough.That's also an idea, but I like damage and as you can see comparing 100 psi to 800 psi, you can't beat HPAIf its going to be a fairly permanent placement (i.e.- always around your residence), you could just attach it to an air compressor and tank with a feed tube from a large hopper. 20,000 BBs and someone will be waiting a LONG time to move before it runs out of ammo
