airsoft bazooka problems

[boom shtick]

hi I`m new to spud files and I am also making my first pneumatic cannon.......but I have some problems. I am trying to build a cannon meant for use in airsoft.I would also like it to look as close as is possible to a real bazooka while also being able to use shells. I have already come up with some ideas but I had to trash them all mostly because of my main problem which is is fitting a power source into what looks like a bazooka. any ideas?

Starting off simple sounds much better. Gives motivation to continue the hobby when its a success. Cartridges aren't rly good to start with(complex)

Coaxial should work just fine, I also think their pistons are much easier to construct. You should provide us with more information on your plans and don't thrash those precious designs away! Show us what you hope to make and we'll try to help you get it to work?

Cheers.
