I haven't made a gun since my marble rifle, so I am getting ready to make another. I need help deciding what to make.
the link for my design for the engine is here http://www.spudfiles.com/forums/viewtopic,p,160005.html#160005
thanks in advance,
Ill say the engine, it would be interesting to see if you get it right and if it works. Good luck.
I would agree. The propane engine would be more of a challenge and if you can get it to work it would defiantly be something different to talk about.
Keep us posted on what you decide. Be glad to help with the design/ construction

wouldn't a pneumatic drill solve the whole go kart thing??
They tend to have tons of torque...
If I ever find one at a yard sale I'm willing to try it for my kid

Can't ask for a better compliment!!
I wouldn't attempt it unless you have a pretty good idea of what your doing... some experience with a lathe and other metal working tools. Not that its extremely but there is a lot of time involved with it and if you screw up on one part, the engine probably wouldn't run right.
Why don't you modify an already existing engine to run on propane?
I am thinking about making a pneumatic engine but I don't think it will be as strong as I want it.
i would say either the hybrid rifle or the large pneumatic because you don't see too many of those and i think the engine would be too much of a challenge for somebody who has only made a marble gun. Though, the choice is yours, just be sure to do your research and have fun with it
if you got big piston areal the pressure will make big torque when it has that large space to work on.
and on a pneumatic you can work with plastic parts you know a proto type of pvc pipe on 120psi then you take the valves and stuff form it to make a metal one at Co2.
a early test can be an 300psi 12v compressor to test on.
(And if you would rather stick with pvc) They do make sch 40 with a 450psi rating.
But if you're one of the cautious fellas, i suggest you go with steel, its cheap and reliable
EDIT: Oooo, i can almost get myself a sig
If I did it right ggft says that I should get 1581 ft/lbs with the large pneumatic. thats at 200 psi with a ten foot barrel.
I got my sig today too
that sounds like a cool idea. You should do some more research and watch some videos of people shooting the cannon you want (or close) to see if it meets your expectations on power and performance. Also, before you make the final decision, i suggest you make some blueprints and calculate some prices to see what your getting into and if it would be too time consuming. Otherwise, i would probably go with something like that, big and powerful!
btw, congrats on the sig after this post i'm gonna get mine...finally
any ideas on what i should do for my sig?
Try and convert a existing engine to either run on propane, its a question of replaceing the carb ect( Some Forklifts run on propane), Or a existing engine to pnumatic.
the engine is going to be hard to make considering that i don't have a lathe or any other tools other than the basics. I might go for the hybrid or the large pneumatic.
Converting an engine for pneumatic would be far easier than building from scratch. They are fairly simple. BUT...it will use air like there is no tomorrow.
Edit: I see Jack was faster yet again.
