I'm gonna do that today just for you sweetcheeks...

>>2744839
Use a lathe? No thanks, I like girls

how much keys could the keyed chuck chuck if the chuck could chuck keys

>>2744839
explain plz
what is wrong here?

>>2744877
>explain plz
>what is wrong here?

Some people get all uppity about leaving the key in a lathe chuck like someone will just run by randomly, switch the gears to the highest speed and then turn it on for some unknown reason... and then the key will magically shoot out of the chuck and fly across an entire building to the elementary school playground across the street and impale some kid right in the eye.

>>2744880

Even though the key flying out of the chuck is the usual stated reason, I don't think that's actually the most likely problem. It's more likely that, if you have a well-fit key, it will get jammed against the bed of the lathe. If your lathe is light, that might just be it. But if it's big and has gears (like the old 17" LeBlond I used to have) it could easily do anything from mangle the key/ways, destroy gears, or, worse, you grab at it in panic-induced stupidity and you no longer have a functional hand.

Source: I committed this sin once. ONCE. I lucked out and the key fell out of its loose fit fairly easily, but it did make a horrible noise, put a nice ding in the ways, and threw the key in my general direction for good measure.

>>2744839
I do this, cry about it.

>>2744839
I just watched woodgears video where he flips the bird at people who moan at this.
Certainly I have rolled my eyes at stories of keys embedded in block walls etc. The benefit of the saga is you can Id a bullshitter immediately.
Machining is boring mostly, some people like that some people dont and have to talk it up.

>>2744877
It's not even really so much about the likelihood of it being thrown, jamming, catching and dragging the operators appendages, etc. as much as it displays a certain attitude towards best practices that doesnt just apply to one thing.

There's tons of "rules" about potentially dangerous power tools that are OK to break when there's no other reasonable choice to get the job done, but this isn't one of those.

It falls under the heading of "may not help or matter, but it *could*, and it can't hurt".

People who are faced with that choice and insist on their right to choose the less potentially safe option for no practical reason are the kinds of people who get themselves and others hurt...and this particular practice is a big sign saying "I'm one of those people".

>>2744880
I've seen it happen. Slammed into a dude's chest and cracked 3 ribs after flying over 60ft across the shop.

>>2744880
> turn it on for some unknown reason...

The office lady that calls herself the “office mom” got tired that all the machinist just stroll in whenever they feel like it and took it upon herself to warm up the machines.

She found an old SOP we had on a dusty clip board.

She turned all the machines on in the morning, with tons of parts in vises that we stopped mid cycle to continue cycles in the morning.

Instead when you power on a cnc machine it starts at line zero

This bitch scrapped hundreds of dollars in parts by running drills and taps through the holes twice, double cut 5 tenths tolerances so they’re out of spec and just basically fucked shit up

Women with “power” in the company get uppity.

One of them was rushing a part to a customer for whatever reason thought she could fabricate something in a lathe from a sheet of arcrylic since she’s watched us do it for years

Work flew out of the lathe fixtures immediately

Machinists, pipe fitters, electricians, firemen, cops, linemen, where do these retards get this false bravado and entitlement from.

>>2745085
>don't chuck me or my son ever again

Anyone got the vid of the shop class fayget thinking he's going to hold the key and stop the motor from turning?

>>2744880
It happened in my uni workshop. Key flew out almost straight upward, through the drop ceiling and stopped against the concrete. They didn’t repair the ceiling after that to show first year students what can happen if you leave it in. The guy who caused it got a mandatory training and leaving the key in unattended now gets you two weeks banned iirc.

But then, that was a shop where 20+ students would just use the lathes in turn and walk around at any time so the chances of they key hitting someone was pretty big

>>2745256
We also had to watch this exact video, he ends up with his entire leg getting caught in the lathe right

>>2745111

>>2745388
Absolutely happened, I even have a “performance log” counting two pieces of scrap (g54 and g56 vises) because of that happening and was told by management I shouldn’t have left it in a state where it was possible to scrap those parts and it was careless of me to leave the parts in the vises overnight…

I explained about origin shift and having to have to hit tight tolerances to a 21 year old office manager who has no machining background as to why i can’t put those parts into a lock box overnight half done

>>2745655

I can't tell if this is just some term I don't understand or a reference to the guy who draws weird bird porn.

a machinist without tools is just a meth head, it's no wonder they tell the same stories

>>2745582
the highschools here have like an intern program they can do with trades and we ended up getting 2 17/18 year old tool and die interns for a semester and one was great but the other one left the wrench on the mills drawbar more times than I can remember; also got to the point of where if he was near a surface grinder i would just go do something else because even after explaining that the big magnet needs to be turned on he didnt turn it on which caused any and everything to go flying/exploding off the chuck

dont know if the lathe ever felt his handy work. Have definitely seen more parts go flying out of lathes than keys though

Come on guys, it isn't hard.

>>2749056
>it isn't hard
But I am, now

when i was doing my training on a lathe the supervisor gave you one warning for doing this. if you did it again you got made to use a chuck key with a spring on it, spray painted bright pink and everyone called you a faggot.

>>2744839
I make welding tests in a fab shop and motherfuckers do this all the time. Or wear gloves/long sleeves. Infuriating.

>>2745085
I can't believe it.
How the hell have you been, man?
Quite a while since I've seen you down at the feed & seed.

>>2744839
I don't get the situation in which anyone ever comes over and unintentionally sends that thing flying. You're supposed to put a part on the chuck before you turn it on? So how do you miss a tool in the chuck?

>>2751916
>So how do you miss a tool in the chuck?

Pure absentmindedness. Too busy thinking about owlussy or something, you just kind of start skipping steps on autopilot, and put the clutch in on the 2000RPM setting without realizing you left the key in after moving the indicator off the part.

You WILL do dumb shit in the shop every now and again. Humans aren't perfect. The best you can do is being in the habit of doing things in a manner that minimizes potential damage when that inevitable dumb shit happens.

>>2751915
>I can't believe it.
>How the hell have you been, man?
>Quite a while since I've seen you down at the feed & seed.

Who dis? Been crazy busy on the farm lately so I've been sending the wife for the cattle supplement tubs. I only make it to town for a parts run now and then.

Stuff like this happening is the reason non springloaded chuck keys are banned in Germany in any educational institution and possibly in general by the Berufsgenossenschaften. These being trade or industry specific company associations that end up paying your disability pensions should anything happen during work time.

>>2752665
>Stuff like this happening is the reason non springloaded chuck keys

I've never used a real lathe so I can't comment, but it's interesting that my Harbor Freight toy lathe has a shield over the chuck that you have to lower before the motor can run, and you have to remove the chuck key to lower that shield.

(I don't know what that other smaller shield does. Mine went in the garbage first day.)

>>2752676
Both of those shields should go in the garbage on day 1. Shields and guards are for pussies. Die like a man.

>>2752665
My lathe came with a spring loaded key, I ripped it off before the first time I used it.

>>2752665
no the real reason is retarded bureaucracy with zero real life experience

Do you people not have guards on your machines?

>>2752748
No
Neither my vintage 10in lathe, nor my modern import 10in lathe ever came with a guard. My modern import milling machine didnt either.

It seems to only be a thing on the super small lathes.

>>2744877
It's the machinist's equivalent of leaving your shopping cart in the parking lot instead of returning it to the corral

>>2752676
>I don't know what that other smaller shield does

It's there to keep chips from flying at you. I really need to make one for my bigger lathe...I'm just waiting for the day I crash into the chuck because a blue-hot chip flew into the hand working the power feed lever at just the wrong moment.

The other guard over the chuck is not just annoying, it actually prevents you from working close to the chuck. I didn't take it off, though. I did like the idea of it preventing the key-in-chuck accident and it helped with oil/coolant being flung everywhere. I just cut it shorter so that it wasn't in the way.

imagine not standing on the bed of the lathe while you run it

>>2752676
First mod most people do is rip that off and twist the two wires in the switch together

That shield actually limits the maximum turning radius of the lathe

And with a little ass lathe like that it hurts a lot

>>2752962
>That shield actually limits the maximum turning radius of the lathe

Post video of your Harbor Freight turning 6" diameter aluminum. I'll wait.

>>2752748
In order to be a machinist you kinda have to already want to die, been that way since the 1800s and throug the 50’a with the chain smoking dudes of the past

>>2752968
Mine actually can if I removed my er32 collet chuck

I have a compound delete plinth installed and a qctp that actually gives me more travel

>>2752969
>in order to be a machinist you kinda have to already want to die
Machine shops hire anyone off the street, there are literally no prerequisites to push a green button

>>2752970
>Mine actually can if I removed my er32 collet chuck

An unmodified Harbor Freight cannot turn aluminum much bigger than about 3 inch diameter; certainly not 6 inch diameter. I'm closing this thread because I don't argue with insane liars. Have a nice day and post more nonsense.

>>2752971
Those are operators

>>2752973

Okay I’ll tell the forums and groups this information dedicated to modifying lathes

Yeah, the dudes who make 18 bucks an hour.

Its a weird bunch
Some people buy a harbor freight lathe, push a green button at work and suddenly pretend they are master machinists.
Easy to sus out too.

>>2752988
So you’re jealous I modified a harbor freight lathe?

You know there are YouTube videos that will guide you through it if you’re jealous.

I’m not a master of shit, I just brought it up because it’s a trade, the pay sucks, for the bullshit knowledge you have to memorize and get paid dog shit.

I’m actually working my last 5 days of it Monday through Friday thankfully this upcoming week

>>2753002
>So you’re jealous I modified a harbor freight lathe?
Nobody is ever jealous of someone who couldn't afford a real lathe.

>the pay sucks,
The pay only sucks if you are stupid. Its really not that hard to get into a job shop, the bar of entry is exceedingly low with how many retards are in the field.

>I’m actually working my last 5 days of it Monday through Friday thankfully this upcoming week
Thanks for the announcement, at least its on record you cant larp as a machinist anymore.

>>2753006
“I now work in an office because I have a bachelor’s degree, but back when I worked as a machinist it was shitty”

Where's that meme on how to filter a name fags so you never see his posts again

>>2753085
Yeah fuck that guy telling you to buy good tools and the guy saying stay away from the machining field since it’s so under paid

He’s wrong on everything!!

Just use tools you found at goodwill

>>2753089
You are completely useless and everyone here hates you. I wish 4chan had polls.

To be honest though, I'm glad he tripfags because it is basically a huge bullshit flag flying over his post so you know to immediately disregard anything he says.

My hero!

>>2744860
There’s a guy in Canada who sells rings that he turned down in a lathe for like $300 a piece. They have maybe $30 worth of materials in them and take about an hour.
>simple ring blank
>semi-precious stones of various colors and sizes
>CA glue (literally super glue but ultra thin and clear)
>several ways of sanding and polishing
It really doesn’t take much, but most people don’t have access to a decent lathe.

There are guides online to making these rings. It really is quite simple. A thin layer of glue is applied to a ring blank (which is shaped like a channel, generally) while it’s slowly rotated. The gemstone is poured on, and more glue is added. Then more gemstone, and more glue, and so on until the ring blank is filled. As the glue is applied, and accelerant is sprayed so it dries almost instantaneously. The inlay material is then milled down evenly with the top of the ring blank. It’s then sanded and polished via very fine wet sanding or jewelers paste (well over 5k grit).

I think with a little knowhow and some shady Instagram shit it could be quite lucrative. It’s also easy to get into just to screw around with, the main hurdle being the lathe. Pic is a popular option of adding pet hair on top of crushed malachite.

I actually enjoy reading tripfag posts because they just try so hard to impress their "friends" on an anonymous board. It is sad and pathetic, and yet hilarious to witness. You just know they're some tryhard blowhard people that everyone hates in the real world just as on the 4chins

I hear you completely and totally man. It seems Hollywood is doing nothing but re-hashing old stuff and "upgrading" it to make it woke, or comic book/superhero bullshit movies these days. Absolutely nothing original. And if it was original, I'm sure it would offend someone and it would be immediately axed.

Sad.

>>2756832
True, the kids at McDonald’s don’t have to memorize which alloys of stainless are prone to work hardening or which alloys of titanium chips are flammable

Or have to learn/memorize which alloys of aluminum have stronger tensile strength than others

Or be able to spot different materials from half a shop away and identify what the parent alloy is

However…. Machinists have to listen to a whole lot less ice spice and Taylor swift music

Also the great thing about machinists is that we don’t live all that long and we’re the career field most prone to committing suicide followed closely by law enforcement jobs

>>2744839
We run contests to see how far we can send it by turning on the lathes.

>>2758468
