Introduction: New Knex Gun Low-friction/high Strength Mech
I made this to hopefully bring a bit more innovation back into knex guns as I've seen a lot of recent guns fall back into the same old pattern of a chamber made of connectors attached parallel to the ram, with usually a release mech based on a connector rotating and releasing from a cut part or some angled grey clip braced against a blue rod. The problem with that design is that it doesn't really align the ram with the ammo, can't hold nearly as much force on the ram (limiting rubber band count), and ends up creating a lot of friction and limited range. This mech uses connectors aligned perpendicular to the ram, and a vertical release to fire the ram, meaning it aligns with the ammo better as well as allows a ton more pressure to be but on the ram because of the enclosed release system. I hope everything you need to know about how it works and is made is in the pictures. I know it isn't that clean a design as it's more a proof of concept at this point. Comment if there is anything I missed or is unclear from the photos. Please tell me if anyone has already used this mech as I'd be surprised if it weren't considering it's simplicity.
Update one: with a single band (no idea how old or what type, I do know it took about 1 or 2 pounds to pull back) I was able to fire a blue rod about 30 ft
Update two: DO NOT BUILD THE MENTIONED GUN AND BUT BANDS ON IT WITHOUT TAPING THE RAM AND CLIP TOGETHER. I put a grey piece on the ram to stop it from firing out of the barrel and had both it and the orange clip hit me in the face fast enough to cause a scratched cornea. tape the orange connector to the black rod if you intend to try it at all. I should have at least a functional shell of a gun within a week, though beautifying something like this in any short period of time isn't really my strongsuite.
Update three: Does anyone have any idea why this shows up as having been published three days before it actually was?
Update four: sent a sharpened rod through my sheetrock and got my knex taken away, so probably can't do much more in the way of testing and design for a few days
