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 ...

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!) some...

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 el...

okay i do not know how to insert images and i have chrombook but is there a way i can skecth on the platform though Go to this website: https://mspaint.humanhead.com Draw your design Click the save button, which will save your drawing to your chromebook as an image file ("myfirstspudgundrawing.png"...

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 muz...

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 nic...

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 a...

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...

Are you making the rounds as well or are they off the shelf units? Awesome work!

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 Good abr...

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 t...

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. IMG_0682.JPG I don't know about you but no amount of fancy ARs or AKs, custom built or ...

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. Did you forget about ME? https://vimeo.com/263675436 Oh man, this post brings back memories of my...

Needs Moar slowmo! Come on - it's 2019 - Everyone has a slowmo camera in their pocket now!

That cannon looks so badass btw - great job!
