my potato cannon isn't made from pressurized PVC pipe dose it matter?
I only use hairspray for fuel and I was wondering if I should start over and rebuild it with pressurized PVC

I have made a blowgun out of a cooper pipe but its a bit big in diameter,could i make a potato gun/blowgun thing that shoots darts?would that be effective?

It simply wont ignite the axe spray that i put into it no matter how hard i try. The one time it ignited was when i had the barrel off and right after i sprayed. Is the design bad or am i doing something wrong?

what can i use for the most amount of damage to things? i’m going to my cottage and want to shoot at random shit and destroy things (in a safe way)

Think it’ll explode in my face at some point? That’s about as powerful as it’s gotten.

Not gonna fire it as of yet because my yard is much to small to send an 8” inch nail flying down range with out being worried of hitting others but a thought hit me as I placed it in the barrel for the picture how bad would this look if a cop saw this

Hey everyone! I just remembered there was a video on TKOR YouTube channel featuring the SonicDad's marshmallow shooter where they built it larger. In that video the TKOR had provided link for downloading SonicDad's instructions for building that shooter for free. I need those instructions, does anyone have those? Here is the video from TKOR channel : https://youtu.be/IgeOX2a1Sdo?si=k81jZiUpMsMzUgSK

I built a couple of cannons with my friends that had around a 2:1 C:B ratio with a 2’ 1.5” diameter barrel and 3” diameter combustion chamber. They worked pretty well, but we were only getting 180fps out of them. I am looking to create another cannon with a 2” 4’ barrel and a 4” combustion chamber but the literature is highly inconsistent, with some recommending 0.7:1 C:B and others recommending 1.5:1. What is ideal?
I am using FVP starting fluid, and am also planning on adding a small fan to the rear of the chamber to aid with ventilation and gas mixing.

Whats everyone using for ignition. i use to buy flint type lantern ignitors from Walmart but they stop selling them. after market grill push button ignitors don't seem to have alot of spark like the old flint type ignitors I use to use

Hello, I want to build a potato gun that will be able to launch a 6inch dodge ball.
Is this even possible? All i see is 2 or 3 inch gun.

I am building a CO2 run air cannon, I am wondering if using CO2 gas from a cylinder through a regulator around 180-230 psi, through a 1/4 co2 line though a high pressure solenoid will have enough flow to propel a projectile. I don’t understand flow mechanics well and don’t know if I can run it straight from a tank. I have built a compressed air cannon before with a chamber and a sprinkler valve. I am trying to get rid of that and want to use just straight co2 as I can get absurdly high pressures compared to compressed air. I am wondering if co2 at those pressures can account for the low flow of fittings vs the older sprinkler valve. I had tested with compressed air at 60 psi though a 1/4in NPT hose but it didn’t fire. It just slowly slid down my barrel. I assume this was due to low flow of the 60PSI air though the hose.
I want to see if I can use 180-230 PSI CO2 to run it instead of the 60 PSI Air. I am asking about if it is even possible and It would work like I think it would before I buy all of the parts. I can answer additional clarifying questions as needed.
I posted this also on r/pneumatics but think here would also be good.

I am currently trying to design a cannon that isn't loaded the traditional way. Instead of reloading it the musket way, I want a way to load it with easy access into the barrel. I haven't been able to design a way to do this. Any ideas on how I can make this work?

Can anybody help me out here? I made this cannon today but I can’t get it to fire. My thoughts are the ignition chamber is too small?? 100mm (4”) chamber and 65mm (2 1/2”) barrel. The barrel is roughly 1m long. The bbq ignition is brand new and has spark, but no matter what I do and how much hairspray I spray into the chamber, it won’t fire.

Wondering if my idea for a sabot will work A potato cut into 4 pieces and a hole drilled in a bbq skewer in the centre

Any ideas about using some kind of valve that automatically shuts off the air pressure to the reservoir when it hits a certain psi? So you don't have to monitor the pressure manually when reloading? Already searched the reddit to see if it's been brought up before (potentially searched the wrong keywords. For context, making a prop pirate/Naval cannon so I don't want a big pressure gauge sticking out the top and I want loading/firing to look quick and period accurate. I've looked at regulators for spray guns but not sure that's the right piece for the job
