But, the reality is that most members are teenagers that don't have particularly good finanical resources, so they are much less likely to be willing/able to take on a project that has unfavourable chances of success.

If I had the money, I'd almost certainly be in possession of a full-automatic combustion minigun. The design I've got is technically sound, it's just not finanically possible.

I work full time but I don't have a particularly large spudgun budget. For example the last time I bought epoxy I forked out the equivalent of 50 pounds sterling, but that was three years ago. Maybe it's the fact that I tend to work on a smaller scale that keeps costs low, as well as my fittings which are almost exclusively custom made to suit my needs.

Most of these kids aren't likely to be quite so short of cash if they were willing to give up or cut back on the usual teenager stuff. Usually an ipod ,an x-box, (possibly) a dirt bike, skateboard, personal computer, and cool clothes come far ahead of experimental materials. I'm sure there are plenty of other things I've missed too.
Maybe they should all put a few quarts of Epoxy on their Christmas list.

I suppose it depends on your other hobbies - if I have to spend large sums of money, I prefer to spend them on my commercially bought airguns than homemade fabrications - though as I said, using epoxy means I save money on buying ready-made fittings.

Believe it or not, I got my first 4lbs of epoxy as a birthday present from an engineer friend of mine when I was just starting getting into pneumatics, in his word "A gift only I could have bought you and only you could appreciate" :D

Well the main problem with my budget, is that regardless of it's size, it seems to only ever be big enough for a single cannon.

The cannon's cost expands until it fits the budget, whether it be £20 or £200.

has anyone got a decent design to get a blowback bolt mechanism to work no matter what the ammo is???

i want to try and build a cartridge based loading system for a pneumatic projectile launcher (gun). i think that a design could be made that could be scaled up to about paintball size or so or be used for pellets and bbs.
