My dad was nearly 80 yrs old at the time and wasn't so much into youtube, however he spent thousands of hours operating high speed air tools which I think is the biggest reason he kicked himself so hard. The thing sounded like a die grinder while it ran and wound up too fast to get off the trigger i...

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 ...

How much pressure are you going for? What will you be shooting out of it and what velocity are you going for? If the answer is "maximum power to shoot a bullet-like thing", then there's really only one formula I can think of that makes sense: 4140 (or similar strength alloy), burst disc, big bottle...

Fantastic work! I’ve always loved tanks and tank combat, so I decided to attempt to make it look like an anti-tank gun, meaning I’d also need to make a mount of some sort. Something that is immediately apparent, I particularly like the elevation mechanism. Also the fact that it's breech loading, I ...

Greetings, fellow tinkerers :) after finishing my first Corona project - a 12mm, 140J PCP operated with a paintball tank (I'll post more about that, I promise) I'm tinkering on a hybrid again. My first try 10 years ago was a rather normal 14mm, 6x piston hybrid, but I had problems with the valve sea...

Hello all, good news!
I reached out to the ATF regarding hybrid spud guns, and actually got a response!
Here's the result:

That's a great response from the ATF. I don't understand and never will why some countries treat spud guns as if they were literal nuclear weapons and the people who build them as if they were literally a dangerous and violent war lord in need of immediate imprisonment. It baffles me why any governm...

Get crackin! Feed us pics and vids.

Time to admit that I've harvested enough Crosman donors for all the projects I have in mind and I ought to get started on one of them

Oh yeah! many weapons before everything is over, that's the slogan. What is this project about? I am curious...

In my country, these hobby weapons are considered directly as firearms. I investigated and asked acquaintances who work in the regulation of weapons, and they tell me that I cannot carry them, nor shoot outside an officially authorized shooting range and with a psychophysical examination ... Stupid,...

Looking forward to seeing progress!

What is this project about? I am curious... 8-) I like the Crosman style grip, very convenient and I have used it before on the "Caselboy" . There are several pneumatic projects I have on my list for which this collection is intended to provide parts, along with an assortment of rifled barrels and ...

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 ...

When viewing posts... the "default" is on the right, which is how it is right now. I had it on the left a few months ago, but did a software upgrade that moved it back to the right. There is a small amount of customization I must do to continue to keep it on the left and have that persist through fo...

Damn, that was lucky. I had a similar experience many years ago with an 8mm ball bearing that bounced back on a steel plate - though I was not struck, it did make a nice clean hole in what was then my bedroom window: https://www.spudfiles.com/download/file.php?id=4643&mode=view A foot or so to the ...
