More compact, more fun to shoot, concealable for journeys to friends house. And likely less accurate. If you saw off your barrel, it is likely that you remove the choke on the end of the barrel. The choke is a slight reduction of the inner diameter of the barrel, found in most airgun barrels. It ma...

lolol dude we get it, your chinese, or your not chinese and you think acting politically correct makes you appear smart, whichever it is just take a joke everyone knows there are way too many chinese thats why theyre only allowed one kid, signatures dont have to make sence as long as they make ppl ...

I also looked for a schrader valve recently. I ended up using the thread of a Dunlop valve: http://en.wikipedia.org/wiki/Dunlop_valve#Dunlop_.28or_Woods.29 Basically I went to my friendly local bicycle repair shop, got an old inner tube for free and cut the valve stem out of it. It seems that the Sc...

I don't want to spoil the fun, but I have seen hot glue projectiles shatter into pieces. The pieces are not sharp or anything, but hot glue in its cold state is not unbreakable. It could break when used as a piston. Still, I think projectiles have to cope with more kinetic energy than a piston. A pi...

well first of all TNW_NL, what caliber/size are your hot-glue slugs/ what is the size of the barrel you are using them for?? I used a piece of crap cellcore pvc that I had lying around. But 32mm cellcore has not the same ID as 32mm pressure rated PVC :roll: Diameter of this slug is about 25mm. The ...

Hi all, I was messing around and found this to be an easy way to cast ammo quickly. Make a hollow paper roll equal to the ID of a barrel, cut it to equal sized pieces and fill it with molten hot glue. The resulting slugs can be further perfected by casting cones with hot melt glue and attaching thos...

Nice that you are trying to put up a modest website, but I think you should use a different way of hosting. These simple start sites are fine but contain a lot of useless links and are limited in appearance. I think you can do fine with a simple static website, but hosted on a real .nl domain name. ...

I have used epoxy on my pneumatic, because it is the only PVC glue available in the Netherlands. They just don't have primer and cement available here. Of course I took great care glueing the PVC together. I lightly sanded all parts and cleaned all joints thoroughly with acetone before applying the ...

Blowguns work fine in general I think. Still, flow has to be as large as possible. I fired my first pneumatic with a bicycle valve turned loose, and it significantly increased opening time of the QEV. When I left out the valve entirely performance was much better. You can easily hear if flow is suff...

Replace it with a car tire valve and drill out the inner bits so it's hollow. This way you can pump it up and use it without having to unscrew the insides every time. 8) I bought a quality bicycle pump with pressure gauge. Now I can get up to 8 bar / ~120 psi. Could go higher, but the sound of pres...

Thanks for all the positive feedback people :) @psycix: Indeed, parts except the pressure PVC are from BTB. Goedenavond trouwens :D About testing, I just went out and shot some spuds. However, I made a mistake by not completely removing the valve connected to the blowgun. That greatly increased the ...

Hi all, This is my first post here, having done some serious lurking :) Anyway, built my first pneumatic cannon, after some months of messing around with combustions and cheap unrated PVC :roll: Specs are as follows: 32mm outside diameter barrel 50mm PVC chamber 1/2" QEV piloted by blowgun And of co...
