Bolt Action Marshmallow Rifle

Unread postAuthor: Jumpin Jehosaphat » Wed Jun 06, 2007 11:18 pm

This is a Bolt Action Marshmallow Rifle.
You can view a basic marshmallow gun that someone uploaded earlier here
http://www.spudfiles.com/forums/marshma ... -t125.html

I took the idea and added pointless but cool features to it.
This is a bolt action blowgun, as far as I know nobody has had enough spare time to make something this useless :lol:
I also mounted a red dot scope to this gun.

I plan on converting this thing to use compressed gas (had it working too earlier this day, but I broke my damn cheap plastic valve :evil:) If anyone has any suggestions for me as attempt to do so I would be glad to hear them.

you should add a valve and chamber and attach it to the mouth piece in case you wanted your marshmallows to have sniper power

Now that is nifty. I kinda wish it was a pneumatics, but hey, it still looks good anyway. How about some paint? Also, does the scope actually make your marshmallows more accurate? It seems to me more like dead weight.

at the mouth peice had a check valve. and for the opening valve have a i dunno blow gun or ball valve. that would be hella tight.

very nice looking. the two things i would change if it were my gun would just be to lower the sight like an inch or so and get a smaller bolt rather than something really long. but thats just my opinion so dont hold a grudge against me :D. but other than that, it looks really clean

@pyromaniac: ball valve would be sweet, but a check valve? that will acompish little and reduce flow

this gun dosn't mean you have no life, if you really had no life you would make a cartridge ejection bolt action no pump action just for a blow gun

A check valve on the mouth piece so you could blow into it to get to a low pressure and have a faster shot.

The whole gun is dead weight if you think about it too hard. Tried and tested, the best blowgun is a plain piece of PVC pipe.

I agree about making it pneumatic, I had it working for about an hour, but I overloaded it and busted the cheap Super Soaker valve I had on it.
I don't want to use CO2 for this because it is expensive...
Would a big piece of PVC with end caps on it work as a chamber? I want to put some serious pressure behind this rifle, but I'm not too sure what to use as a pressure vessel.

Yea but hey, why have one long piece of PVC when you can have a bunch of small bits and joints that make it look really cool?
