Re: pneumatic spearguns...

An example of the Crosman "Rocket Spear Sea Gun" came up for sale locally, were it a different economic climate I would have contemplated purchasing it but alas, these are difficult times and choices must be made :roll: It did however persuade me to do some more digging and I found the patent . http...

Re: Hybrid pumped weapon project

Very interesting (and creative use of Tippex!) and good that you made it work!

I had done some experiments with lead projectiles sealed in a breech when playing with hybrid cartridges, metal on metal there were no leaks and it worked to about 8x if I recall correctly.

Re: Semi-Automatic Airsoft Pistol

Very clean, I'm guessing it's a double-action trigger and a simple "tee" bolt?

My Fionda works the same way.

Re: Hybrid pumped weapon project

Is it my impression or did you use balsa wood in the construction?

You can always tell when a spudder is also interested in model aircraft :D

Re: Hybrid pumped weapon project

Very clean work, nice "proper" evolution after all that prototyping...

I like the markings too, although perhaps it's more of a Fuerza Aerea (+Butanea) Argentina sort of equipment :D

Re: Spud gun disguised as classic artillery

That is some beautiful work, excellent job!

I second the advice to properly meter fuel and as to ignition, instead of a percussion cap perhaps you can use the same hammer to strike a piezo that will generate a spark?

Re: Anyone seen this PROOF yet if so or even if Not check it out

Fascinating device! From what I can tell, it's a variation on the detent BBMG using a flexible seal as a detent. I had made several experiments along these lines, here is one of them in 3mm caliber. One of the issues I encountered is that the following BB plugged the barrel too quickly, so the air w...

Re: the air cartridge we wanted

Interesting stuff! It seems to go around laws restricting barreled weapons by effectively being a spigot gun without a "barrel" per se. I've found a picture of the cartridge internals: https://i.imgur.com/zm2eNsH.jpg My impression is that it is the exhaust valve piston design we all know and love, w...

If you'll be using butane gas as a fuel, it will all be used when you fire, so you will have to re-inject fuel and re-pressurize for every shot.

still not the same as sawing into some pipe yourself.
In adulthood it is gratifying to add some movie classics from one's adolescence to the collection :D

I'll agree however that it's nowhere near as satisfying as designing and building your own.

Re: Auto Gas Design

Interesting design, if I understood correctly it's intended to cycle with a constant flow of gas?

I think you'd have to try it out yourself.
Maybe not, given this appears to be a bot account promoting whatever is in the signature.
