spudgunner survey (help me out, guys!)

codongolev · Fri Nov 04, 2011 9:18 pm

oh, and the numbers can't be changed after the survey is started, which kinda sucks. oh well, I guess I'll just try to make it work.

and we were kind of determined to make a combustion cannon, by the way. we like the bang (and also the challenge it provides).

If its an engineering class, wouldn't you guys prefer pneumatic? 3way and a cylinder? Plus air is free, hairspray costs.

PNEU-MA-TIC!!! PNEU-MA-TIC!!! PNEU-MA-TIC!!!

Screwing together a few fittings (Sorry PS), isn't much of a challenge, nor is a basic fuel metered combustion. A machined hybrid on the other hand is, not to mention the satisfaction of stupendous chamber pressures.

That's true, that's very true Zeus.

a hybrid would be interesting.... I've thought before about making something that compresses air and explosive gas before to get a ridiculous explosion, but it always seemed like it would be too difficult for my skill set.

actually, I already have somewhat of a design in mind, it's just ironing out the kinks that's the problem (and the whole making it cheap/easy thing.) it's basically just a regular ol' combustion gun, except that it's got the ability to quickly reload multiple times before needing to be refueled. I don't want to get into too much detail until I've actually made it, but that's the general idea.

also, I like your profile pic, zeus. I should probably get one if I plan on sticking around, eh?

I took the survey, don't see why not. As Fnord pointed out the numeric ranges are a bit strange, good luck building a automatic reloading and refuelling spud gun (or whatever it was) for under $80 that's actually decent.

Anyway, hope you stick around.

pneumatics in the high-pressure range have a mighty bang and if you wanted a challenge you could engineer all the parts by hand

Moonbogg · Sat Nov 05, 2011 12:39 am

I took it, but the questions seem a little noobish. For instance, the cost of my meter pipe costs nearly as much as the largest cost bracket in one of your questions. You won't build an auto-anything for anywhere close to 80 bucks. That is maybe enough to cover the cost of shipping for material to build such a cannon.

If you want to keep it cost efficient then build a pneumatic. You can get a lot of power and have full auto for much cheaper. That is, unless you actually will be shooting potatoes. That would mean you would have to build a cutting action into it. Do you necessarily have to shoot potatoes?

just found the link of the semi auto combustion

There's always this too...

how 'bout this
hmmm, not very practical though

codongolev · Sat Nov 05, 2011 8:52 am

pneumaticcannons.... that was... wow.

I'm not sure that we'll be able to pull that off.

sorry that the numbers were "noobish." I think I should've made the objective of our project more clear. we just want to improve the basic cannon without raising the price all that much.

If your original intent was retail sales, you are partially correct. If your goal was to produce the best product you can, you are wrong.

anyone can design a potato cannon that's really nice but really expensive

"Really nice" and "really expensive" are a subjective things. Because you also qualify as "anyone"......show me.
