Hey wyz what did you use for the barrel on your pcp rifle that you are currently building??

Hahaha cheers man, your place sounds pretty awesome!

Here are the trails i ride. They are pretty awesome and alot has changed since this event. Im not in this video by the way haha.

I ride bmx dirt trails, like big jumps and stuff like that, but im pretty keen to get a downhill bike soon!

Yea thats what i was thinking, because it seems to pilot alot of air before it shoots. Thinking of machining up some delrin (i think thats what iv got) to put in the back with some screws holding it down

well here are some pictures of the two air guns.

Well it is very simple, i was very suprised by how simple it is and how well it works, here is a link to it.

i made the piston on the lathe but i can remember what the material is i think it is delrin maybe. Ill take a picture later today of it

Edit: I forgot to say thanks! @Jrrdw

Hey guys here are my two air guns. One is a Golf ball cannon and the other is a semi auto marble shooter. I currently have no pictures of the two air guns but i do have videos of them. The golf ball cannon does have a pvc stock but i took that off before i went to shoot it and make the video and it ...

hmmm im starting think that i might use a burst disc for my first hybrid since its really simple, but how do you know what type of burst disk you need to use with the mix? E.g. Coke can, tin foil and so on.

so when the Fuel air mix ignites it shoots the piston back letting all the pressure out, am i correct??

Edit: What would you use for a sealing face? would you still use rubber or some other material?

Hey guys im thinking of building a piston hybrid because i hate the idea of cutting out burst disks and what not but i just cant seem to get my head around on how they work? Iv got a metal lathe and all them goodies like that so building it shouldnt be a problem once i find out how it works. Im plan...

i have just used the paper clip to see if it would work!!
