Re: 3D Printed Air Tank and Barrel

VERY cool construction method! It's basically been dangling in front of my face for a decade as someone who was big into early 3D printing and loves composite work. Thank you for showcasing this. I may still stick to TIG welded chambers in my work but I love seeing innovative ways to hold pressure.

Re: HGDT & GGDT SUCK ARSE!

Yea sometimes work arounds are okay in an edge case like this... I agree though - hard coding them in can cause more unexpected surprises down the road lol!

In terms of updates/on-going development (not that we expect you to keep this bad boy constantly upgraded!) - I imagine that you would use the ...

Re: HGDT & GGDT SUCK ARSE!

I was able to access the google drive link, download the google sheet and open it in LibreOffice Calc. I'm able to run Pneumatic and Hybrid scenarios without any strange behavior. Using Combustion I need to size up the barrel or the interior page of step calculations seems to hit a snag (#NUM ...

Re: hello guys found some new badass spud style combustion launchers in the quite advanced style

Extremely fascinating work really - The design and execution of the piezo anvil style fuze was very well done. Not 100% sure if it's shown in the youtube video but thier PDF file on patreon breaks down how they harvested the piezo components from a common clicky type ignitor. Architecting all the ...

Re: Hybrid handgun with rupture disc

Very cool - I've often considered this same concept in a 1" -1.5" bore configuration (more shoulder rifle sized than anything) but using the piston valve hybrid design so I could use generic round ammo without needing to reload a burst disc every time (golf balls or similar lol).

Any idea of the ...

Re: Commercial options for semi auto bb gun with on gun bb storage


How about the Steel Strike , more of a modern tactical look than the 760 but features a 30 round magazine with 900 round storage on a semi/burst capable platform.


Damn that thing is cool! I knew I would find some good recommendations from this group. As much as I'd like to make something - it's ...

Commercial options for semi auto bb gun with on gun bb storage

Recently I've been looking for a good camping option for cheap plinking. My goal is to find something that can store hundreds of BBs and the user can reload an on board loader to hold ~20 BBs at a time to be able to fire in quick succession (repeater with bolt style) or even pure semi auto with an ...

Re: fl(air) gun - mechanically locked pneumatic cartridge for a 26.5mm flare gun

This is amazing. I love all the effort to keep it looking stock and completely reversable if desiring to use a conventional flare. The use of the CO2 powerlet sections as ammo is also very clever in a world of expensive ammo. I've utilized them in the past on builds and it was fun shooting full ones ...

Re: Any official studies of Hybrid Cannons?

This is one of the few examples I remember of a publicly available paper from Utron's contracted government research project for a "Combustion Light Gas Gun" (CLGG) - A.K.A. a badass hybrid that many strived here to get close to.

Full paper here: https://apps.dtic.mil/sti/pdfs/ADA462130.pdf

Re: Look what I found!

I'd be interested to know what their design operating pressure is. I don't see mentions on their site or their literature except for the spark plug and electrical feed through - which say 500 psig.

Not saying they wouldn't work as often there is a safety factor in play but it might be worth asking ...

I need to get back to building. :/ I've had AR parts lying around since last fall but I finally got around to getting a lower a month ago and have been building that instead of the cannon I need to be finishing.

Re: "Offtopic-posts-topic" NSFW



Welcome back, Gunfreak. NOW BUILD SOMETHING! :D I might design a large bore soup can launching monster. I think my next cannon should have enough recoil to just about put me on my ass. It's called for.
