Thanks to a commenter on last week’s Now That’s A Knife post for pointing out that Jeremy Hanson’s Spudgun Technology Center has a custom machine for rifling PVC pipe to make more accurate barrels for potato cannon. They sell several varieties of rifled PVC (including clear) in assorted lengths. The way I hear it, the rifling machine was first designed and build by STC founder Ed Goldmann. [Thanks, Bryce Bell!]
Thanks to our commenters for pointing out that, contrary to my implication in Monday’s bolt-action spud gun post, Jeremy Cook—cool though his project certainly is—is not the first person to build a breech-loading potato cannon. Not by a long shot. (Heh, sorry.)
Jeremy Cook advances the potato cannon arms race from muzzle- to breech-loading eras with this .602 caliber pneumatic spud gun prototype that fires from a high-pressure gas reservoir instead of via the familiar fuel-ignition system.
