Welcome back! I also came back in 2019 I think it was, after many years. I built a cannon in 2009 I think it was, then came back right around 10 years later and built a real banger piston hybrid. I'm not real familiar with pneumatics in general regarding innovations, but people are still posting new...

I was feeling nostalgic and decided to see if Spudfiles was still going. I had an account here in 2013, and had so many builds to try out but no money. Now I'm financially stable but I lack innovation lol. Since 2013, I've lived in several states, graduated college with a degree in Mechanical Engine...

Agreed - this has been popping up a few times lately. First noticed it happening while doing some work around Christmas. It is due to user sessions not clearing as they should. Cleared it up for now but I suspect it will come back, have some TLC needing to be done!

Thanks for the heads up.

Shame it's so quite in here. Ah well, the tinkering continues and holes are still being blasted though innocent cans :D Here is a second version of the flare gun cartridge with a steel chamber and aluminum piston. Fitted with a 6 inch long 0.75 cal barrel it's pushing empty 12 gram CO2 capsules at ...

The video I owe around here, of the single pump pistol. In this case, they shoot 1/4" steel bb^s. I have currently switched ammo to 0.23 gram airsoft pellets ; It has about 3.5X and the performance is very good. https://youtu.be/QsRumkMX9NQ?si=n4GxjqizYdjECYNE The operation of the gun in the video i...

I am including a couple of simulations made by Jack, on this weapon. In one case, the combustion chamber works with 180 cm3 of air and in the other, with 150 cm3 of air.

Híbrido MB largo, diseño final..png Hibrido monobombeo 2, secuencia de operación.png Here, chewing on a single-pump hybrid weapon, but this time, long, to fire pellets. It would be necessary to use considerable force, about 45 to 50 kg to compress this device. Of course, I have to use my body weigh...

Very nice. I'm half tempted to get one myself

3d printers are wildly useful for these projects. Obviously not all parts can be made from printable plastics, but I can't tell you how many times I've had to print a specialized mount so I could put an irregular object in my mill vice. This is the current project. Internals are 304 stainless. 3d pr...

I made a tennis ball cannon using a 3” sprinkler valve. It fires a ball at ~150 yards at just 30 PSI. The valve is manufactured by Dorot, repackaged by Galcon, and sold by Drip Depot. The stated flow rate is 390 gallons/minute which is 10x the flow rate of an average 1” sprinkler valve. The valve is...

Merci pour ton retour il est construit entièrement en acier inoxydable, les matériaux en impression 3d sont très résistant et le canon est à âme rayé grâce à une presse hydraulique pour pousser l'outil via des rallonges pour 1m Le projectile est de ma conception avec une forme G1 Cb 0.536 https://i....

You think it's bad here? Try getting involved in making pulsejets :P "the death of the forum" has been ongoing for a while, with several technologies vying to take its place. All sorts of gamifyng and the like, and it pulls users from forums with glitz and pizzaz, but the problem as I see it is that...
