Discussion Overview

The discussion revolves around the design and construction of a mechanical device intended to launch projectiles, specifically a pitching machine without motors. Participants explore various mechanical arrangements and parts identification while addressing the feasibility and safety of the proposed device.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant seeks assistance in identifying parts and mechanical arrangements for a device that uses a lever to store energy in a coil and launch projectiles using rotating cylinders.
  • Another participant requests clarification on the type of energy storage intended, questioning whether it involves a spring or an electrical circuit.
  • The original poster clarifies the goal is to create a pitching machine that operates without motors, aiming to launch projectiles for hunting purposes.
  • One participant expresses skepticism about the practicality of achieving sufficient power in a portable design for hunting larger game, suggesting that existing technologies are more reliable.
  • Another participant proposes an alternative approach using arrows instead of balls or bullets, suggesting that a mechanical weapon could be developed that is less efficient than crossbows but still functional.
  • Further ideas include creating a relatively silent mechanical weapon capable of firing various projectiles and the potential for unconventional designs like a "tether gun" or net gun, although these ideas raise legal concerns regarding hunting regulations.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility and safety of the proposed device, with some expressing doubt about its practicality for hunting while others explore alternative projectile types and designs. The discussion remains unresolved regarding the viability of the original concept.

Contextual Notes

Participants highlight limitations related to the power output of the proposed device and the legal implications of using certain types of projectiles for hunting.

trying to make a device but don't know what i need, only what i need it to do...

my aim is to use a lever (ratcheting) to store energy in a coil, then route that energy
to a pair of vertical cylinders making them spin counter and clockwise or left spins left and right right

any help identifying parts or gear/mechanical arrangments would be much apreciated


sorry for such an oddball question but I've had this project stuck in my head for years,
and i have no other resorces at my disposal
 
Engineering news on Phys.org
It would help a lot if you tell us what you want the thing to do.
Also:
When you say that you want to store the energy in a coil, do you mean a spring or an electrical circuit or something that you sniped out of your girlfriend's medicine cabinet or...?
Your description isn't really too bad compared to many that I've seen, but it is incomplete. I'd rather not form any opinions as to an approach until I have a better idea of what you want.
 
my point is to basically make a pitching machine without motars
i just didnt want to say it cause last place i did, griefed me about wanting to make a "dumb" version
of an already "better" and proven technology

im looking to waggle a lever 2-3 times, pull a trigger, and launch a projectile
using 2 rotating cylinders or wheels

basically making a "gun", I am hoping to have enough power to hunt boar with it (after getting it approved for such ofc) but a small game or target shooter would work just fine
 
Well, I certainly don't want to "grief" you, but I am seriously doubtful that this can be accomplished in any practical manner. I can't see that anything portable would ever deliver enough power. The best pitching machine in the world wouldn't kill a boar unless you were throwing grenades with it. (I wouldn't even trust my life to a lot of existing guns if one of those suckers was annoyed with me.)
I'll think on it, for sure, but I'm not very optimistic. Sorry.
 
Okay, I had an idea, but I don't think that it is in line with what you want.
If you're willing to switch from balls or bullets to arrows, something lethal can be arrived at. It won't be as efficient as existing cross-bow designs, but might be okay to play around with.

thats what i was thinking,
since guns function based on explosions

i could make a relativley silent by nature mech weapon cabable of fireing both bolt/arrow
and stone/steel orbs

also having the possible bennefit of being classified as a "dangerous waepon"
instead of a "firearm"

if i wanted to go super crazy, could potentialy make a "tether gun" using harpoons/hooks
or make an attatchment for net gun
totally illegal for hunting (fair game laws)
but neato for showoff or setting up pulleys

im sure the effective range is going to be really short 30yrds or so
but that's all one should need really (depending on the game)
