It's a piece of weld wire and a selector switch, if you can't build based on that then you probably just shouldn't ever try.

>>34045907
Hey dumb fuck, non-engineer. There are ambiguous dimensions. This is going to lead to scrap and rework. If you want 50% rejection rate and you have money pouring out of your ass, go for it. My shop would NO BID on that shit design.

>>34045941
It's not that hard to follow the dimensions follow the sides they are drawn on.
And I'm far from non-engineer, I'm a couple of credits away from a degree in nuclear engineering, not everything mechanical has to be complicated, print to scale, bend to match, try it and tweak it, it's not nuclear physics, it's an ak.

The nice thing about CAD is that it will yell at your if stuff is under defined. Like soldiwork and the yellow coloring of lines and such.


So really in 2017 there is no reason for stuff to be ambiguous. And if you refuse to use a computer to draft up your giggle devices then you're a weird individual...

Since it's apparently legal up here to mill out AR lowers to be all ready for F/A parts (MINUS the third hole, that shit is a no-no), how would I be able to take these blueprints and use them to mill out an already completed AR?

Stressing again that it is COMPLETELY LEGAL, as long as I don't drill out the sear hole, which I have no intention of doing.

What pressures would it be able to stand, or would you cast it with the lost pla method?

>>34047178
The bolt carrier slaps the tiny lever as it goes into battery, which then trips the disconnector, and bam the hammer drops.

>>34047178
Also it uses the rear takedown pin as a pivot.

I've made a few things

>>34047556
I have tested it, it doesn't go very far unfortunately (working on remedying this) and it actually takes quite a bit of force to puncture, so you kind of have to throw them down the tube instead of drop them

>>34047633
I could see printing one and putting it on a friend's AR in secret, is there a forgrip model as well?

>>34047748
Oh, have you tried smoothing out the inside of the tube, and the mortars?
How are you sealing it?
I could see using a similar system with multiple co2 canisters in the bottom of the tube and a heavier mortar to punch them all at once.

>>34045564
>Im personally interested in carving wax and trying to cast it in a hardenable aluminum alloy.

That's faggotry because you still have to MACHINE your casting. Learn to machine instead. Casting is next to useless for home hobbyists and what's worse, a diversion of time and money which could be directed to machining.

Casting and printing are fine for toy crap, but that's not how the vast majority of firearms are made and until printing evolves dramatically it's a waste for making guns.

Do what works. Or not.

lol either CNC or a million man hours on a manual mill with lots of setups.

Either get 5+ milling machines and use a particular setup on each one to make certain cuts or start from a casting like every other manufacturer does.

A CNC would work too.

If you were subcontracted to manufacture a part and then the company who you're making the part for starts telling YOU to eat the costs because the parts you made which have no manufacturing defects in them but were poorly designed by that company for their intended use (shit you wouldn't be able to diagnose anyway because you don't have any of their assembly drawings, only the drawings for the part you're manufacturing), what would you do?

If you purchased a car and a vital component breaks, do you give a shit whether it's the car company or their subcontractor who is paying for the warranty work? No. You're just pissed your car broke, the car company is probably being a giant asshole about giving you a loaner car and you'll probably buy your next car from a company with better designed vehicles that don't break down as easily/often.

The Manager's method of dealing with the situation is just spreading the shit around a larger area, not actually cleaning it up. If you hand a problem to an Engineer, he will try to actually engineer the problem out of existence.

So maybe you think a manager is just there to make life hell for the people under them, but I've actually been lucky enough to have good Eng. Managers who gave a shit.

*whiiiip* Back to work slave!

(jokes aside, it made me cringe in the project room when I saw my mates modeling shit like that.)

>>34054087
I've always made it a point to try and un-fuck everything I can. It's amazing how much shit goes for years without being fixed.

One time, I opened up a model and saw that a fastener was referenced from an old, obsolete library. Most people would just leave it at that, since it wasn't causing interference in the model or anything, but I decided to dig a bit deeper. It turned out that the fastener's model was actually a pack&go of another one and had the written specification changed, so the model wasn't an accurate depiction of what was called out in the Part List/BOM. Then, it turned out, the specification written in the PDM software was different from both what the model showed and what the Parts List/BOM called out. So the system was automatically purchasing screws that had a different specification than the ones in the drawing which were different than what the model showed and THEN the guys in the shop were actually using a COMPLETELY DIFFERENT screw on top of that! So we had so many of the fucking screws that were specified in the PDM software that were automatically ordered for god knows how many contracts but were never actually used, so I fixed the model, made a copy of that screw file in the newer standard part library and then told everyone else in the team about it so that whenever those screws would fit for an application to use those instead so that we could go through the massive overstock that was building up in the warehouse.

>>34052220
This isnt what manufacturing would use, there is an entire technical data package for those details

>>34054222
>not just taking the crates of screws and shooting them out of a cannon

>>34054435
Man, you should've seen the faces people made when they found out.

The worst part is, the model had actually been revised multiple times, some recently, but the person who worked on it was a huge cunt who only continued to work there because nepotism is apparently stronger than incompetence.

>>34053788
Sounds like sound advice, how long have you been in the industry?
I always preferred hand drafting over computers, but I suppose CAD is the standard now, I'll just have to pick it up.

>>34054781
Hand drafting is dirty as hell and revisions are the worst. I'd rather use AutoCAD and I hate that software with a deep passion.

You only really end up drawing things by hand as back-of-the-napkin brainstorming or quick note-taking.

>>34054868
Well, at least I can still do it for work at home, where the manual machines will roam free stationarily about the shop.

I also learned that a lot of /k/ fucking hates me for doing this

I've always liked your lower, it's pretty cool, when I acquire a 3d printer In the future I plan to experiment with stuff like that.
Ever tried adding steel inserts while it's printing?

Honest question from a newly minted engineering graduate. Is the most important trait understanding that the last 4 years have barely scratched the surface?

Surely, if this is actually the case, then entry level engineering positions should have a heavy focus on training the green out of you, right? The job postings I see don't reflect this.

>Prof says if you actually need to know GD&T wherever you go to work, they'll train you
>entry-level position listings say I need to know it on day one

Maybe you're expected to oversell yourself to HR and then undersell yourself to your team? I just want to be honest about what I do and don't know.

What am I looking at

is it feasible to digitally scan a part to get the precise dimensions and measurements in order to make a new one?

>>34060211
No, not really. The scan will be noisy, so you get the issue of choosing which points more accurately represents the surface of the part. Cheap calipers would be just as reliable, but for different reasons.

>>34060259
I see so the technology isn't really there yet. I figured that would all be digital these days. it is possible to copy parts without blueprints right? I guess that is what I'm really getting at. how difficult would it be to copy the design of a lower receiver?

>>34060294
>Assuming you're an American and therefore you downloading weapon designs from an America hosted site is not an ITAR violation

Prints for AR and AK receivers are out there, go find them.

For the more obscure stuff, you're stuck taking measurements with whatever gauges, micrometers, and calipers you have access to. Depends on the design, but something like an AR lower could easily take a few days of work to fully measure and draft.

>>34045988
As true as that is, an off dimension in a part like that could cause the gun to not fully go into battery or other dangerous issues. So I'm gonna side with the machinist fag.

>>34060344
unfortunately it is an obscure part, which is why I asked. thank you for your insight.

>>34056596
I haven't done soidworks in some time, though I am czechnically certified (at least for amateur hour type suff). Under defined is when you're making the program make assumptions about how lines will interact, right?

Can someone see if the webpages of this site can be saved and added to murdercube archive? It has a ton of good info on improvised EFPs as well as plans for an IR detonator that (well according to the guy who made the website at least) is jammer proof. You need to know how to solder and basic electronic engineering/ assembly to build the detonator but it seems pretty straight forward.

>>34060435
Kind of? The issue is that solidworks is almost always "making assumptions" about how lines and solids interact -- those are relations and mates. To go full jargon, under-defined is when the location or size of an entity is not fully described by relations, mates, or dimensions. In other words, there exists one or more degree of freedom for one or more entities.

The geometry solver in solidworks isn't perfect, but it works well enough for common scenarios. For example, if you want to fully define a rectangle, you need to define the location of one of its corners relative to origin, and you need to define the size of each pair of sides. The perpendicular and orientation (vertical, horizontal) relations take care of the rest.

In 3D, you're either making a 3D sketch, or you're mating components together. Component mates are pretty easy for most of what you'll ever draft. However, you can run into situations where you're playing around with circular arcs in 3D, and you might get instances where you would expect degrees of freedom to exist, but the constraint system says they don't.

Sorry, you probably wanted a simpler answer, but under/over-defining stuff in solidworks isn't intuitive at the boundary cases, and you need a solid understanding of geometry to get why the program might be disagreeing with you.

Simpler answer: under-defined sketches can (ususally) be dragged, under-defined assemblies (usually) have the same trait.

So I'm in school right now to become a machinist, and I figure without CAD programming knowledge i'm practically useless. Thing is I'd like to get a head start this summer. Are their any online Solid Works tutorials that are in depth and decent? Also how hard would it be to get a student copy?

>>34060719
Simple PVC Frag grenade. The author says to use Acetone Peroxide but fuck being "Mother of Sataned" and use ETN or other less sensitive explosives.

Probably HMTD or Lead Azide. DDNP is also an option.

>>34060719
Are you American? If so...

Do you get many international students studying, and if so, how easy/hard is that as a possible route to residency? Also, how much does it cost?

>>34061120
Yes, theirs probably 5-6 foreign students in my machining 100 class. Depending on ho a much money your willing to spend and where your from it shouldn't be that hard. Student visas aren't hard to get.

3D scanners create what's called a "point cloud". If you were to draw a cube, you would draw the lines that define the borders of it. What the machine sees is millions of individual locations on each surface. Not something you can really measure off of.
Are scanners useful? Yeah, but mostly for more "organic" parts with lots of curves and shit.

That all being said, that's not enough to reliably produce working components.
Let's say you grabbed 100 units of a single component. All units were made on the same machinery using the same drawing. All of them passed QC and all of them work as intended. When you go to measure the diameter, all of them are slightly different and all a little off from the nice round number you'd expect them to use. That's because, in a drawing, you start with a "nominal dimension". Let's say you start with 1.000". The hole you're putting that piece in is also nominally 1.000", but you want to be able to put the piece into the hole by hand and not have to use a ten ton press to get the thing in. So you apply an Engineering Fit. You look at the Fit chart for the most appropriate kind of fit and apply that. So on the drawing, you'd say that the 1.000" shaft can be between say .9955" and .9975" and the 1.000" hole can be between 1.0000 and 1.0035" either by writing the base dimension with allowable variation, writing the limits or by writing the nominal dim with the Fit specification (1.000 LC8, for instance).

Reverse Engineering is a lot more difficult than it sounds. Making a one-off that works fine isn't that hard, but if you just measure a part and it happens to have a dimension on the very edge of what is acceptable, if your production dips past that point, you just lost potentially thousands of parts. Even if the part costs you only a few bucks, it adds up quickly.

>>34057399
Late reply, while possible to do it youre better off cad modeling a hole and epoxying a bolt in there after printing. The timing, planning and risk isnt worth it.
Also one issue is that in the ar lower the weakest spot is right under the buffer tube by the safety. There isn't a lot of room for strengthening there.
Best way to strengthen is integrating the grip and doing away with the safety.

My first engineer job was dealership service receptionist...

My first real engi job was 3D modeling and drafting for a injection mold company.
They were like a lot of no engi idiots in this thread. Yes, they know all about playing with those millers and CNCs, and you have to learn alot from them because usually, uni doesn't teach that, although mine did.

There was only 1 engi at the company apart from me and he had the same job as me, albeit making a shit ton because he was l33t shit, a fucking pro at modeling. But he sucked at engineering.
At that company no one knew what the ISO 2768 meant. They all used fucking H7 tolerances but there wasn't a single plug gauge in the entire facility to check those.
One time some one sent a TD to a customer with an H7 tolerance. Obviously, what did the client do? They gauged it. And being my company didn't have proper QC, it failed, it was too wide because they were checking it with g6 shafts from Hasco or Meusburger.
So the client asked for pictures of the plug gauge we used, they are still waiting to this day I supposed.

I had a 6 month contract. 4 month in, I started searching to get out and 3 weeks after I was asking my boss to accept my resignation so I could sign for another company.

Now I do nothing but mail and calls, but I work half and gain double(triple before taxes).
I miss playing around in CREO and SW but I don't miss people that think years.exp=master.degree.

First place I worked at out of school did ~80% of their work with sheet metal and tubes that they'd cut and weld.

Not a single one of their drawings had a fucking welding symbol on it. They would put an arrow with a written note that just said "weld here". Unsurprisingly, they had a lot of issues with the wrong welds being used and in the wrong places. Once I got the engineering department on-board with using welding symbols, we start putting them on the drawings and we suddenly have a bunch of welders stomping into the office, huffing and puffing about it like we're trying to make their jobs harder. It turns out, none of the welders had actually studied welding in school. So I had to fucking teach the welders how to fucking read welding symbols.

buy a shitty Dell machine and put a newish GPU in it, then pirate solidworks and install it on the dell.

do not connect dell to the internet and do not install on main PC because lol Chinese pirated software

that would be the absolute cheapest option IMO

Use a slower speed and slower feed for hard materials

Use a faster speed and faster feed for soft materials

Do not drill through machine screws with HSS. The screws are harder than the drills

probably depends on if the screws are chinesium or not.

I'm a machinist, have no cad experience. Most jobs I come by can be done with a bandsaw and a Bridgeport, it's always good to have any experience, let the drafters draft, you worry about machining and fixing their fuck ups

>>34063894
>let the drafters draft
I really wish people understood that.
Just about every job posting I see these days is asking for a degree in engineering. If you have an engineering degree, are you going to do a shitty drafting job that you barely know how to do when you could be earning significantly more by actually engineering?
