I was horrified, after I took a #macro #photography and saw that my "clean" finger was filled with #swarf #particles imbedded in the #fingerprint after 3 hours of just teaching in a #machineshop that day.

What's with all them hashtags

[–] Seaguy05@lemmy.world 38 points 1 month ago

I #barely made it through the #title

[–] LiveLM@lemmy.zip 26 points 1 month ago* (last edited 1 month ago)

Pixey.org is a Pixelfed instance, and Pixelfed is basically Fediverse Instagram.
So I assume using tons of hashtags is normal over there, but when the content federates over to Lemmy it ends up looking wacky.

Feels like the old school way of social media. Sort of like 2015 Instagram.
Disliked that stuff then and now. Sort of feels like pollution. :/

[–] Zak@lemmy.world 16 points 1 month ago

OP is actually using Pixelfed.

[–] vala@lemmy.world 6 points 1 month ago (1 children)

Ok but these hashtags still are not relevant to the post at all.

[–] KeenFlame@feddit.nu 1 points 4 weeks ago (1 children)

because that's how they have been since the nineties.

[–] Lemminary@lemmy.world 1 points 3 weeks ago

There were hashtags in the 90s?

It’s because they’re not posting via Lemmy; They’re posting via Pixelfed, which is something more akin to a federated version of Instagram. They @ the relevant community or users to make posts/responses; notice the “@pics@lemmy.world” in their post. This is also why you’ll sometimes see comments begin with an “@{username}” of whoever they’re responding to. On Lemmy’s end it looks out of place, but on their end it looks more like an Instagram comments section, where @‘ing people is necessary to be able to follow the comment thread.

It’s one of the odd quirks of federation that can be difficult to wrap your head around when you’re accustomed to every single social media site acting like a walled garden… Federated posts are able to federate not only to different Lemmy instances, but to entirely different platforms.

So no, it may not be fucking tumblr, but for them it is fucking Instagram.

[–] gofsckyourself@lemmy.world 5 points 1 month ago* (last edited 1 month ago) (1 children)

I'm aware. Still fucking hate it. I hate Instagram, too.

[–] drkt@scribe.disroot.org 3 points 1 month ago (1 children)

do you wanna federate or not

[–] gofsckyourself@lemmy.world -2 points 1 month ago* (last edited 1 month ago) (1 children)

At the expense of this kind of garbage? Then no.

I'd be happy with being able to choose to opt out, or ideally opt in.

I don't like being forced into a platform that I don't want to use. I don't use Instagram, Tumblr, etc. for a reason.

[–] drkt@scribe.disroot.org 6 points 1 month ago (1 children)

but you can

Go to an instance that doesn't federate with those other instances you don't like, or run your own and do whatever you want.

[–] TheDoozer@lemmy.world 2 points 4 weeks ago (1 children)

Are those specific instances that are federated in (that can be separately blocked, like people do with .ml)? Or is it just another access point for any given instance?

[–] gofsckyourself@lemmy.world 0 points 4 weeks ago* (last edited 4 weeks ago)

This post was posted to pics@lemmy.world via pixey.org, a pixelfed instance.

Since the post is on the pics@lemmy.world community, it cannot be blocked using the blocking features available. Unfortunately, Lemmy does not have any feature that would allow blocking this, which is exactly what I am lamenting in my comment.

As a machinist I will tell you that it's the pieces you can see stuck in your skin with your eyes that are the real problem. Those usually hurt a lot more. Machine shops are filthy and it's up to you to wear glasses and gloves and wash up with soap containing pumice.

A bigger concern to me is the cloud of coolant steam containing lord knows what billowing out of a lathe. I've started wearing a winter coat and hat during work with a fan blasting right at the door to keep the air I breathe clean.

Anyways neat picture. Judging by the tiny chips it looks like the mill is to blame. Makes me glad I run mostly lathe these days. I had something like that in my elbow for a few months. It was about one centimeter long and hurt like hell when pressure was on it.

If you want to run machines the first tool you should buy yourself is good tweezers. I have 6 different pairs of tweezers. You can borrow workshop tools but should stay sanitary and have your own tweezers.

Not a machinist, just an amateur fab guy but sweet Jesus carbide burrs on a die grinder suuuuck for that kind of thing. If they weren't so good at material removal I wouldn't have them because those damn micro metal splinters are the worst. I used to get them stuck in my socks because my shoes were loose and then they would stab my feet.

[–] Maalus@lemmy.world 4 points 1 month ago (1 children)

You're wearing long sleeves and gloves when running a lathe?

[–] moody@lemmings.world 7 points 1 month ago (2 children)

The danger depends on the type of lathe and the tools being used with it.

In metalworking, you would probably be using mechanical lathe tools, keeping your hands far away from the danger bits. In woodworking, you may be using gouges directly on the wood and want to keep any dangly bits as far away as possible.

[–] Maalus@lemmy.world 3 points 1 month ago

Nah, even in metalworking, people do lots of stuff around lathes and get hurt because of long sleeves. Like running sandpaper on round stock which is a common thing people do. Anything that spins means no rags, no sleeves, no gloves etc. And for good reasons

[–] Widdershins@lemmy.world 2 points 1 month ago

I do CNC lathe. I could run it with the door open but don’t due to coolant. It shouldn’t run with the door open but it does run like that. Safety interlock is long gone. I roll my sleeves back on my flannel jacket and button the cuffs. I sweat a lot and the breeze that brings me fresher air makes me get cold easily.

I have seen the Tool Time episode where Tim The Toolman Taylor has his shirt ripped off by a lathe and am very aware of the danger every day. The green button doesn't get pushed until doors are closed.

Get a room.

The residue from grinding metal. Mostly oxidized metal.

[–] Xanthrax@lemmy.world 12 points 1 month ago

Maybe try a strong magnet?

[–] BlueEther@no.lastname.nz 10 points 1 month ago

Not a machinist, but do a little light engineering/maintenance at work... Went for a x-ray on a suspected broken thumb and the tech asked "how long have you had the fragment of metal in your thumb?"

[–] drosophila@lemmy.blahaj.zone 9 points 1 month ago

Just as we shape our experiences so to do our experiences shape us; the swarf is a part of you now.

[–] marius@feddit.org 7 points 1 month ago

Yes, skin care is important when working in a shop

[–] jawa22@lemmy.blahaj.zone 5 points 1 month ago (1 children)

Wait until you have to mill something like GP03 or Kevlar phenolic. Steel has nothing on those levels of discomfort.

[–] Appoxo@lemmy.dbzer0.com 2 points 1 month ago

On Youtube some 3D-printer creators showed close ups after printing with carbon fiber. Both of the material surface and the body.
Very lovely stuff (not).

[–] altphoto@lemmy.today 5 points 1 month ago

Yup. I've been obsessed with cleanliness and aluminum part finish at the nano to micro level. Stuff happens very easily to any machined surface when you just touch it with bare fingers. Its incredible how much of this we never care to see.

Like people bring up micro plastics and they ponder and ponder where it could be coming from. Meanwhile they're scraping stuff off their eggs with a plastic spatula against a PTFE surface. Sure PTFE can withstand the heat, but it's still very easily damaged by rubbing on it with something else. And this is why we're all getting cancer early.

[–] ryannathans@aussie.zone 4 points 1 month ago

Now imagine the micro and nano plastics on your fingers every time you handle plastic

[–] ikidd@lemmy.world 1 points 4 weeks ago

Horrified? This is just a Tuesday if you do anything around metal.
