https://youtu.be/3mROfmdKqAg This yasu user gets the noise with the detonation. Check out his channel on youtube because it is interesting to see his concepts and techniques for simple, semi-automatic and fully automatic noise cannons. Maybe it will come in handy for your future noise cannons or lau...

I can pierce 0,7 mm sheet steel That's quite impressive for lead pellets to be honest. Have you tried with more than two layers of foil? No, I'm just using the gun with two rupture discs. Surely you can break three, with a little more precompression load, I estimate with 10 - 11X. At present it is ...

CHEAP, UGLY AND FUNCTIONAL! :) There is a caveat in that "pretty is as pretty does", so when something is functional, there is a certain beauty in it regardless of its aesthetic attributes. If you're right. There is an aesthetic of the function, which is independent of the aesthetic itself, (easier...

I did a test at 11X with a 16g .22 pellet and three disks, as Jack suggested. He drilled into an old 1mm stainless steel military pan and the noise is quite loud. The pellet seems to have penetrated through, but it was useless to find traces...The damage is in the first photo. Orificio acero inox. 1...

Oh yeah !! it's the same... Keep in mind that your post you name here is my bible on this. I not only remember it, I have it complete in a word, on my pc and on a DVD... It is exactly the same as what you made, I only made it in the form of a weapon to be able to shoot and aim, with the air pump inc...

LBC, sistema carga bolillas acero .25 (2).png Upgrading the single-pump gun. I'm trying to build the drawing. It has associated to what is in the drawing, a loading system for 6.35 mm bb's to make it a repetition weapon 8-) I'm working on a rough prototype to test the concept. The goal is for it to...

Here some photos of the "monster" that works very well! :D It is unfortunate that it only compresses at 3 bar because the compression cylinder that I used has an internal diameter of 26 mm, which is a lot to generate without any lever, more pressure. What's nice is that you can shoot on repeat and i...

New design and prototype of the single-pump handgun, the "Plink .25". It shoots 6.35 mm steel bb's, because I'm interested in reusing ammunition. There is no point in wasting lead, (more expensive), on this weapon designed for plinking, simply. The pre-compression pressure is 6X and it can go throug...

Small video that shows the operation of this short weapon.

It is possible to increase the output energy by at least 30%, because it is not very hard to compress, (about 9 - 10 kg), but since the objective is to mark the objective, only that, I have decided that the energy does not exceed that, and not too hard to compress, I mean comfortable to operate. Tha...

I share a home video of the firing test of the "LB - VI" semi-automatic pellet launcher. :) The bb's gas loading drive works perfectly, with the appropriate modifications that I invented for it. It fires 6.35mm steel bb`s, and can hold 11 in the ammunition tube. The feed works by gravity, and has 5....

An idea that can be used is embodied in a very low-power compressed air gun, which was very popular around here a few decades ago. To compress the spring, you have to rest the barrel of the gun against a hard surface, floor. The main advantage is that you can use almost your entire body weight to ge...

That's cool but would it be better than something like this ? I was actually about to pick up a tank and pump for a future project. That bottle is much more expensive around here. A paintball canister costs about USD 242 against USD 23 for sodastream. The regulator has to be sold separately, it cos...

Testing this "sodastream" aluminum co2 canister as a low cost compressed air tank. 0.6 liter internal capacity, 250 bar factory test pressure, and 166 bar working pressure, lightweight. The regulator is for co2 from 0 to 7 bar, and supports about 150 bar at the input. Normally I inflate it to 120 ba...

What do you think... can it take a lot of speed out of a cup-type pellet, have moisture in the barrel at the time of the shot? It is a 24" .22 caliber barrel with 12 microrifling. It's not water, but if I pass a cotton ball through the inside of the barrel, it comes out quite wet. I have noticed var...
