Hypothetically, if I wanted to build a basic prototype off an old patent, how should I go about it? Start with a 3D printed model?
>>65548638I really like the concept of this old Reifgraber patent and I'm curious if it would actually work.

>>65548647Where does KelTec brand cocaine fit into this?
>>65548651that's for the ideas guy
>>65548638If you could get an accurate model to print, it would give you a tangible and basic idea on how it would function mechanically.
>>65549237Local community college has engineering classes and 3D printers you can use if you pay or bring your own material. I might start there, but I would need help 3d drafting the blueprints.
>>65548638>have to pivot "slide" out of the way to chamber first roundwack
>>655486383d printing and CNC are powerful ways to quickly create something from computer drawings. There are also services that will print or machine custom parts to your specifications.Overall I do recommend having physical prototypes as much as is reasonably possible so you can iterate testing.
>>65549756No, you press down on the tail end of the bolt to unlock it. Pulling the trigger then retracts the bolt, loading the gun.
>rear of bolt tilts down and then moves backwards>barrel and top cover don't moveI'm not really sure what causes the bolt to tip.It is really kind of a blowback with a fixed barrel and tilting slide.
>>65549783There's a gas port in the barrel.
>>65549773Interesting
>>65548638Keep us posted.
>>65549470They typically will not allow anything firearms related. You probably would need to do only the internals and under false pretenses.
>>65552895He should make a rubber band or nerf gun or something. Or is that verboten now?
3d printing a reference model is trivial if you already have a strong grasp of CAD software. If you have any interest in pursuing stuff like this I'd suggest taking classes on drafting and CAD, it's very hard to teach yourself or learn from youtube videos. I've been fumbling my way through it and once you get past basic geometric shapes it's very laborious and unintuitive if you don't actually know what you're doing.
Gather all the information about the thing you want to re-engineer. Are there prototypes, instruction manuals, assembly breakdowns and parts lists?Freecad is an open source alternative to commercial CAD programs. Plenty of documentation and tutorials around also.
Without dimensions a drawing is practically useless
>>65553599I understand that 3D printing a working prototype is anything but trivial though?
>>65548638If you cannot draw the parts so that someone else can reproduce them, nobody will care about your idea.
>>65553916I think this is where one should start talking about how AI still can't fold their shirts.
>>65553646Well yeah, the idea would be to print a prototype to inform the actual milling of the completed firearm. Being competent at CAD is harder than the actual machining though it requires less of an investment.
>>65554044>Being competent at CAD is harder than the actual machining though it requires less of an investment.Disagree there. Machining is an art and a science that requires a good deal of practice to become even semi-competent. Just clamping an irregular shape to a mill can be quite a challenge.
>>65548651everywhere.
