Something I was thinking about

Hi there, Its been a while since I've been on here, but there are always those periods I am thinking about a idea. I was wondering if there is a posibility to make a recoilless hi-power arrow gun. The idea came from the stakegun in the game "Painkiller". In order to manage this, I have thought of th...

Thanks! Ehm in all the video's, it's a 28mm pipe ;) I'm not sure how much I get with ggdt. I don't really know how to use that program.

You are totally right man... Another lesson learned xD Thanks.

I know, but I wanted to shoot it again in a long time, charged it up, and forgot the target. Also I couldn't find a target at the time. You can say, a bit unprepared... anyhow, it was alot of fun :D

Sorry for the thread kick up, but I had to post this new video here of the buckshot test :) Tell me what you think.

PS: There was no progress (more add-ons) prior to this video.

I think you owe us some videos ;)
I'll try to make some for you guys. I need a suitable place to shoot, a good backstop, and some nice targets.

It's been a LONG time since I took a look at this site, but I bought a .395 Lee round ball mold from ebay, and cast MANY bullets. It does fit perfectly in a 12mm copper tube. And I think they are also avalible for 15mm copper tube. Also it's very useful to make buckshot. I call it 10×10 buckshot. 10...

Now this piece really comes clear :idea:
I still need to know a few things :oops:
1. Rod returning spring
2. The thing where the piston slides in
3. Piston bumper

Thanks in advance :wink:

I might have discovered how it works. I still have a few questions. How did he manage to make the qev so short (if you get what I mean). If you watch his other video how he made the qev, it's much larger. Also I need how he made the rod returning spring. I drawed something that might be true. http:/...

I have to make this. I always have a hard time understanding pneumatics, so I want to ask you if you would do a diagram video, like you did with the barrel sealing piston valve. BTW I am butaangas on youtube. With that said, this is the first time I ask a video request.

I want a 10mm short sniper rifle for homemade lead slugs. I want a bullpup design to get it short, ergonomic, and to keep the power and accuracy. That's my main goal. I might change the design to like you guys said. Instead of piloting from the side, I will make it pilot on the bottom where it's plu...

hmm this looks interesting... can to us something more about the design, I mean what sort of pressures are we talking about?? also that looks like a buttstock... that's pretty cool but it means that the BV will be very close to your shoulder... I mean much too close The pressure I want to use is 50...

Now I get it! Thanks! :) EDIT: I placed the ¾" tap in the middle of the piece. Will the sides hold 60bar? It's about 1,5mm on each side http://img535.imageshack.us/img535/7848/tapf.png EDIT #2 I made a scetch of the dimentions. What do you think? http://img218.imageshack.us/img218/8003/scetch.png
