is this safe?

ok im going to be making my first canon...its going to be just a basic combustion canon...what im asking is it ok to fire it in the cold...i've heard that pvc can get brittle in extrem temps.

I cant testify to this seeing as where I live its not cold, but how cold is cold where you live? If it is "cold" from what I gather from other posts is store the gun inside and fuel it then go out side and shoot it then come back inside. If you do it that way there is not enough time for the PVC to adapt to the cold so there wont be any way for the PVC to become brittle. Also dont expose it to cold surfaces either (snow) seeing as it can change the temperature of stuff pretty fast.

i dont shoot my cannons outside below about 40 degrees, during the winter when its like 0 here i will do like pimpmann said and reload inside then go out and shoot and come back in.

if you're thinking about using it in a snowball fight (just an assumption as people have asked me about it before) forget it, it will fire too fast and if theres ice it becomes a flying piece of ouchy or death

ok thanks a bunch guys

[darkpyro]

i have used my cannon to shot snow balls before but never at any one and i know that it takes a while for the barrel to get really colled or the combustion chamber

[neilman88]

im happy because i finallt found the "perfect mix" for my gun and when its like 35-40 F my gun kicks ass(shoots hard and all) so i cant wait for the summer, i hope it make like a 5-10 meter difference or something

The biggest problem I've had with spud guns on really cold days is if you drop it on a hard surface or bend the barrel a lot handling it ,something will
probably break.So IL try to leave them alone on really cold days.

It's f'n freezing here (MI). I keep my gun inside. I fill my gun inside and do one shot at a time on the deck. Hey BLB, you got any numbers on the combustive properties of LP at sub freezing temps?

[beebs111]

i know that propane still works in cold temps but not other fuels. i imagine that it would work better when its warm tho...

[Damien]

butane and protane still work n cold temp but hair spray and other deoderants dry really fast in hot or cold which can stop them from working

I have to use one of my launchers from time to time in the winter months for geese control. I keep the launcher inside where it's warm. I simply load the spud, charge the meter pipe, and wait until I step out on the deck to dump the propane into the chamber. I don't actually shoot at the geese as its really not necessary to even hit them. Just a close shot does the trick and the noise also drives them away.

Used to go through a case of Roman Candles a year scaring them off, these launchers are a hell of a lot more fun! (well maybe not for them)
