Since I am known as the "SpudGun Expert" at my school, my principal asked me if I could make a launcher for shirts and hot dogs for football games...
It doesn't need to be powerfull...just to launch the stuff atleast 50 yards at a good arch so nobody is injured.
The chamber is planned to be 4" and the barrel has to be 3".
I am debating whether to use an over-under design with a sprinkler valve (2" ports) Or whether to make a QEV. Has to be hand-held ( can be below the waste with handles) and weigh a maximum 15 lbs.
My question is what design should I use and what specs/pressures would work best for lightly-launching T-shirts?
I searched everywhere for "T-shirt launchers" and came up with nothing...
Your fellow spudder,
I'm getting paid $250 (including a kick-ass paint job...)
School colors = Purple and Yellow
Mascot = Indian
oh yeah.... completely skipped my mind...fast refill, totally portable...thanks
still unanswered questions...
I would reccommend a piston valve but a 2in sprinkler would work too, itll just cost you twice the price
And i wouldnt go too overkill on the chamber, you would'nt want people going deaf. I would reccomend a 24in long 4in chamber at most.
I wish I got a task like that at my school

I hope that was a typo lol...
and yeah...a piston valve would be good but I would rather stay away from the homemade stuff as far as internals go because if something goes wrong with it...my ass is grass...
and I wouldn't go overkill at all...if anything, underkill (if that were a word)..
Well If you dont want to go homemade then yeah, 2in sprinklers your best option.
And yes that was a typo, sorry about that.
And completely off topic but i just read your sig and couldnt stop laughing for like 5 min
yeah...ill stick with the 2" over-under then. unless there are objections?.. (cricket chirping).
Alright then! Over-under it is! Thanks for the help guys...ill make some blueprints and post them later.
lol, like the sig eh? just thought it up after reading one similar to it in an e-mail I got... I loved it so much it deserved a spot in my sig
Does the $250 include material cost, or is that for your work? With a regulator, 2" sprinkler valve, and assorted parts, you may not make much profit... but that may not be your goal
thats what he will buy the cannon for, I pay for parts...
and yeah...way i figure it...the maximum this gun will cost me is $100-$120
maybe even less.. oh, then the regulator...another $50 max (i got connections).
$120? What sort of CO2 setup are you planning? Are you getting some parts for free?
Wait so the entire gun is going to cost you $120 when a 2in sprinkler costs $80 minumum and the reg will cost $50. There is $130 right there and you also need the fittings and pipe so Id say your looking at more like $160-$170 minimum
That is unless you got connections on the sprinkler valve too.
I found some on ebay...$35 buy it now...
already ordered this afternoon just one though
link is a secret so don't ask...just search yourself, still like 5 left
Thats a really amazing price!!!!!
I just had a quick search on ebay for it and came up with nothing.
Does the link really have to be a secret, maybe i can get some guys to force it out of you jk
