Bounce a short distance, against the concrete wall, about 50 cm. I was about to point the gun at the target, a cardboard box with a lot of newspaper inside, and I accidentally pressed the spark gap before aiming exactly at the target, when the wall was just ahead ... Calaculo, if you shoot me at 10 ...

Don't beat yourself up over it. Bad things happen. That's why we try to be careful, but bad things still happen sometimes. We all have our stories and experiences. You shouldn't feel shame for what happened. It was an accident. They happen. Maybe try lead pellets instead? Steel tends to be pretty b...

Added a front grip/charging handle (from a drill) this makes it soooo much better. Flip up iron sights, bit of foam on the cheek rest, and took the grip off and filled it with silicone cause it was loose.

Having the o-ring go past the transfer port in high performance applications is not really a good idea. Well, you were right. :roll: Did work perfectly at the first try on the PCP air pump, everything sealed fine, popped open nicely at about 30bar - and sheared the top of the O-ring clean off. Seem...

I got a serious engineering job out of school and that's moved me into an apartment and diverted my attention towards some more electronic/computer projects Been there... it will get better! I like the idea of a captive piston with some serious venting at the front of the barrel. I'm imagining the ...

In the house I can shoot about 30' and the dart hardly drops in flight, I need a Chrono really.

Project update. 8-) I built the hybrid's wooden stock, I think it looked nice. I also finished everything about the machine itself. In the photos you can see the parts, the .25 caliber barrel, the bolt system, the piston valve with automatic pilot opening and closing of the pilot, which I described ...

I was working to finalize and test this weapon, I think it was decent, and it shoots very well. I built a stand to store the weapon, and to use it when needed. I just fail to install the open sight, which I am building with the greatest dedication, because the barrel is a jewel, and it is very preci...

With some lube this is now shooting at 160fps, full length darts will also fit.

Update: it works! I’ll probably make a separate post with some more details, pictures, and videos. Thank you to everyone for the inspiration and ideas, I almost forgot how satisfying a successful launcher is! It’s a simple concept, but somehow so unique and quirky

Tried that with a smaller version and there was too much twisting torque on the handle to get a smooth operation, would need some linear bearings like this one.

After an 8 year hiatus... I figured I'd give some closure to what happened to MFIC. Long story short, she had a short but eventuful career. I eventually finished her, lost subsequent build photos along with MFIC herself in my divorce that happened 3 months after my last post here. I'll try to give a...

Shot a few shots agains today, something happened to the video during export though. Will have to do for now.

My new toy. It shots nerf darts and everything attached to a dart. The Problem with the "uncompressable" venturi mix is solved by some valves. . The first valve is a one way valve operatet by gravity. from there the mix goes in the Chamber. it is coaxial in the T-Piece. there is a 1/2 inch steeltube...
