Re: Two Italian WW2 helmets found
Nice find! The lack of rim does make it seem like they are paratroop helmets: https://i.imgur.com/hEJdoxC.jpg Worth doing a bit of research as to the exact units involved as to my knowledge it was mostly Alpine troops in this area or operations. Indeed, I hope there is more stuff left on that locat...

Two Italian WW2 helmets found
Now I am hooked.. Yesterday I found two Italian WW2 paratrooper helmets on a slope of a local mountain. This region where I live was under Italian military occupation from 1941 until Italy capitulated in 1943. Judging by the shape, I am pretty sure they were manufactured for paratroopers. My grandfa...

Re: Concrete ballistic shield
That's interesting! Reminds me of the Panzernest: Given the mobile nature of modern warfare, I don't think fixed positions have much value. The average infantryman has access to a plethora of weapons with shaped-charge warheads that can deal with meters of concrete. There's enough footage of ATGMs ...

Concrete ballistic shield
Hello everyone! This is a shield I made a month ago, which I plan to test with my homemade airgun. It was cast in a TV parabolic antenna, two layers of rebar were used. Sand was washed several times to remove dirt and clay. As you will see, the outside section is the weakest. https://youtu.be/m7TGtb...

Re: Spud gun powered by cooking oil?
Has anyone been experimenting with this concept any further? Hello PCGUY :) :) I have not experimented with this concept yet, as I do not have the proper tools and resources. In my mind, I went through this idea many times. There are many brilliant individuals here on Spudfiles and if someone decid...

Recover steel bearing balls/spheres
I don't know about you, but for me steel spheres are very valuable as ammo. I can never find enough of these from old ball bearings, and once fired outdoors, there is a low chance of recovery. I am aware than these projectiles cause drag, and from what I observed there is probably a loss of 5-10% of...

6mm BB gun conversion kit
Hello everyone! This is my 6mm BB gun that is composed of a blow gun, bike pump adapter and a barrel made out of 2 pen tubes. The footage was recorded during the summer, but I totally forgot to upload this project. I built it in this way to save parts and to easily convert my regular ball valve airg...

Re: Spud gun powered by cooking oil?
Hello! :) At first glance the system seems quite complex in general. In my opinion, shaping the mix is going to be quite difficult and inaccurate, as I say, at the first sight of its publication. The issue of ignition is unnecessarily complex, having a small piezoelectric lighter that instantly spa...

Spud gun powered by cooking oil?
Hello everyone! I would like to share with you this rather crazy combustion cannon design. I am fairly convinced that it could work, but there is always a chance that the design might be flawed. As always, I am looking forward to your opinions and ideas. To better understand how this cannon is suppo...

Re: Automatic Combustion Chamber Idea?
It can be a simple option, introduce the pulverized fuel and mix it with the air in your explosion chamber. T How would you vaporize alcohol, like a quick injection? Sounds great to be honest. Anyways, do you think it would be safe to fill the majority of the tank with alcohol and use less volume o...

Re: Automatic Combustion Chamber Idea?
So my suspicions are confirmed, definitely not a safe design. Perhaps the only possible way would be to fill the majority of the reservoir with alcohol and use as little pressurized air as possible. And even the military don't keep the fuel and oxidiser together in their *designed for purpose* fuel-...

Automatic Combustion Chamber Idea?
Hello! Again, one of those hypothetical scenarios, it might sound silly but here is the idea. The device would be composed of two chambers connected with a hammer valve. The first chamber is the reservoir in which pure Alcohol (Ethanol) and pressurized air would be stored. The idea is also to heat t...

Re: Possible way to increase pneumatic cannon power?
Yes, heating it up would increase the theoretical performance of the gun. However, ball valves absolutely suck and the use of one would cripple you as compared to a normal pneumatic with a proper valve for the application. Beyond that? It's a lot more energy efficient to just put the gas from the s...

Possible way to increase pneumatic cannon power?
Hello everyone! Recently I was thinking about this idea to increase your pneumatic cannon power if you are limited by pump source. I have no idea if this could work. I have an ordinary bike pump which can go up to 6 bar and currently don't have an electrical air compressor. The idea is to create ful...
