Re: GGDT and HGDT

Sorry for the late reply on this. I saw the links had been posted, so I did not want to take any further action until SpudFiles had been upgraded. I would really like to add a new page dedicated to GGDT and HGDT. The page will go in the main menu bar on the top/left of the revised SpudFiles look. Th...

Re: I see we have a new skin …

Overall it looks good, nice to see that everything now loads properly over TLS, and the new skin is far more aesthetically pleasing than the ~2013 iteration, which made the site look like a shitty nerf gun forum from 2003. This may sound harsh, but with that abomination in the scrapheap where it be...

Re: "In the world of spuds today"

Thanks Al! Nice acquisitions, and quite a big step up from the Sherline. It is! At first I was just going to move the Sherline from work to home. I realized however that even though I now have access to the great outdoors, I still hadn't moved away from the "pen gun mentality" so to speak and the Sh...

compact precision launcher

Velocity test on a can of water:



Almost finished...

It has a 1/2" qev, 0.875" barrel. My first breechloader I think. Barrel short enough to muzzleload an arrow.

Going for a California-legal look.

Re: Describe the ultimate potato cannon

A spud cannon that pays it's own way! Once that happens I prefer a pneumatic barrel sealing piston valve 2" or smaller with built in air compressor. As for the rest of the build 2:1 rule of thumb works well. Add on's would be but not limited to built in magazine for easy loading and less of it. Int...

Re: Describe the ultimate potato cannon

I confess that I've not really thought about the details of the valving since I doubt I'd get the funding to build such, burst disks work well, and burst disks are a negligible cost in the Big Picture. The point being that whimsy aside, the gun would almost certainly use burst disks. With the valve ...

Re: Describe the ultimate potato cannon

A fully automatic 40 x 400mm cannon based on the 40mm Bofors with pre-charged x10 hybrid shells. Tho that would never generate enough gasses to cycle any kind of gas operated action, and you would most likely want that thing to have a locking bolt. Thus either an entire pneumatic standalone piston/c...

Re: Describe the ultimate potato cannon

I swear to all things holy and not, if I had the money lying around, I'd build it. I would actually be crazy enough to go through with building this thing. It would be absolutely hilarious. Let's just say that I didn't come up with the performance specs on a whim. I was asked by some folks if it wa...
