I bet you will get alot of damage with those compound rounds the one thing i love about this cannon is that botl system that fills up the cannon with the right amount of propane in it. But i love th whole cannon in general.

Holy crabs shoot it at a watermelon or rockmelon make a nice explosion like the ones in the slow-motion videos where you see the bullet completely rip pieces of fruit a apart. Hmm that's one way to make fruit salad

He he the tech shed at my school has a number steel tubing in different sizes and lengths but i don't think my teacher want me to use one, he will probably be to suspicious of me. :lol:.

hey if i maybe i can do a under over type setup and have a larger chamber yet a keep a good ratio. I hope he ...

thankyou for your advice , hehe i hav done done that before with a 12 inch metal spike :D wnt through 1 inch of fiber board it had a hell of a kick to it (i was firing it like a shoulder mountd firearm) the spike least weighed 1kg.

If i use all pesure rated pipe thn could i use propane rather than ...

2 inch pressure pvc end cap goes right into a 2.5 barrel (tape needed) but boy watch out this thing is strong i bet you can launch one of these at a brick wall and it will still survive

It does fly stable without any fornt weight added i laucnhed this thing least 300m (1000ft) with the Excaliber ...

Geeze being a while since i have been on here :roll:. Anyway here is what im trying to make. I trying to make a a spud gun that is use ammo that is 0.75 inch in diameter and i was asking wether i could make this thing powerful but with a barrel that is not too long.

nice wrk man , ha that combustion chamber is huge . geeze you would think with soo much pvc with the launcher u r holding in the photo it would be farely heavy. BTW how m,uch distance can you get out of the
combustion

probably a 12 inch long piece of metal tri-stake rammed into a silicon tube went through least 1-2 inches of fibreboard

some Airsoft fields are not allowing launchers made out of PVC even at 100psi because they are afraid PVC cant handle any pressure. Even though PVC can handle the pressure, they are kind of ignorant and don't believe you when you show them the pressure rating. Now I realized I said Airsoft Fields ...

Ok i will go look at that this weekend , maybe while im there i can go get some 50mm end caps for some rounds you know the nobby lookin ones they only need a few mm of tape to seal the deal might get some decent accuracy out of them.

oh well i like blue anyway

kewl where can i get it , bunnings possibly.

well they hold for me, someone said to wrap it in cloth tape to make it stronger , is this true.

the label said it was DWV, but the wall thickness is (for the tee) 2-3mm the glued part is 3-4mm .

For best opinion i will ask my old buddy Bubba05 who i haven't spoken to for a while and he uses the ...

i will consider that option FORE, however is there any way to reinforce the cap with anything, Cause i really like the way i can separate the ignition system from the cannon so i can clean it and not wreck the ignition.

But i think the reason why the cap failed is cause the round i put in the ...

Maybe i might install a fan to mix the air better with the fuel, i think this might eliminate the smoke problem
