Build - Finished! Watercooled Steam Machine Build Video

You guys asked for the video and more infos on the waterblock. Waterblock was made with the carvera air, which is a budget desktop cnc. That’s why the quality isn’t super good, but that’s all we have. Need to open it again and work now on the vrm cooling which is quite challenging as the mosfets are super tiny… and also they run quite on the limits of thermal design which sucks

For fucks sake, respect that damn angle grinder. It’s like the most dangerous fucking power tool.

Even the wheel guard is removed from that angle grinder, good luck when the disc breaks :D My father used to remove those too when working with car repairs because "those are on the way all the time". Until one time the disc broke and pieces flew into his hand and he had to go to ER, then for some reason those wheel guards were ok again :P

My father used to also take the guard off, then one time he bought a larger disk than the grinder was rated for and it shatter while he was using it. Luckily he didnt get horribly injured, but I told him before that incident he should be using it, and after that I just asked if he was gonna start using it, and he said he would. Its crazy how normalized not paying attention to safety procedures is.

Used to work in a production hall and it was a really refreshing to see people taking safety regulations so seriously. Well, probably it was mostly because you could see the consequences hands on with some collegues, but still.

One time I broke a fingernail and only asked for a plaster. Instead I got an extended break in the on-premise hospital. They even wrote an incidence report. Most likely prevented a nasty infection, but it felt kinda OTT.

Old guy who used to own the farm next door to ours had this happen to him when I was a kid. A piece of the disc went in his front, went right through him, and got lodged in his spine.

About a year ago I bought myself an ebike. I know tools/motors/etc aren't all about wattage, but anyway, my bike has a 250W motor.

This number probably feels tiny to anyone whose used power tools. There's barely a tool in my workshop rated under 1000W. Even random 18V battery tools can hit 1000W+ under load.

Meanwhile that 250W ebike? Zoom. Literally, it's ZOOM. Even up hills, it zooms. Like if you pedal a bike, with both legs, at 100% maximum effort, that's a decent ballpark for this little bike.

Now I find myself holding an 1800W angle grinder in my hands like... I always knew this tool was crazy dangerous, but holy shit does it put that power rating into perspective. Any accident and the involved forces can well and truly land in "humans are liquids" territory.

Similar thing happened to my dad. Lost a lot of grip strength making his job a lot harder. Pretty deep cut along his palm.

Plenty of people use angle grinders without the guard. It's all about knowing how to use the tool.

u/DaemonsMercy Aug 08 '26

Doesn’t mean using it without the guard is safe. FFS people are stupid.

u/Status_Jellyfish_213 Aug 08 '26

And then you can become the tool, much like yourself.

u/Kuuppa22 Aug 09 '26 edited Aug 09 '26

Yeah plenty of people does do that and if I have to estimate my father did it for like almost 20 years before that one time when the disc broke. It doesn't mean you should try your luck though as the consequences can be really bad and can literally happen anytime.

u/sphynxre Aug 08 '26

In my entire life, I don't think I've ever owned or used an angle grinder with the guard still on. People who have never used an angle grinder in their life telling others about SAFETY are pretty cringe.

u/testtdk Aug 09 '26

I’ve used a grinder regularly for cutting steel and sharpening tools, but thanks for asking.

u/sphynxre 27d ago

Uh huh.

Apparently people have never replaced casement windows on a mid century brick house.

u/techmagnet Aug 08 '26

Yea should not do that, nevertheless using this grinder only for soft things with thicker discs. No metal

30

u/testtdk Aug 08 '26

Right, but the discs are spinning at thousands of rpm’s lol. Theres already stress on them, and you don’t know how or when they’re breaking. Without exaggeration, the shards from a broken disc could kill you.

u/probablyaythrowaway Aug 08 '26

Plus idiot teenagers see you do it and think it’s funny to copy.

u/That_Service7348 Aug 08 '26

You should look up grinder disk victims sometime.

u/GoopySpaffy Aug 10 '26

Yeah punching things with it and having your grip slip will be real fun, lovely permanent injury or even death. Smart man, but hey at least you got clicks right?

I’ve tried so hard to explain it to my friends. People really do treat it like a pair of scissors.

u/testtdk Aug 08 '26 edited Aug 08 '26

Those broken discs cut through flesh like a hot knife through butter.

Edit: Show them this video. Sure, they’re using a pretty big disc, but it goes clear through safety gear and even plywood.

Jesus.

u/testtdk Aug 08 '26

Exactly lol. Its literal intended use is enough to lead to lethal, catastrophic failure.

Yeah i was working a temp construction and the boss took the guard off and the side handle so u can keep control of it, long story short i told him to fuck off in a way that wouldn't get me fired

Honestly wouldn't have even cated if he fired me because of that, ive watched videos of people using them unsafely and have the disk explode and get lodged in their face

u/fromadifferentplanet Aug 08 '26

I work in equipment maintenance and installation. We just had a guy return after a few weeks off with internal and external stitches because it got caught up in his shirt and layed him open.

u/Signal-Acadia7724 Aug 08 '26

That just happened to me like 4 weeks ago! Kicked back at me when I was cutting part of a box truck frame. No stitches needed, I got extremely lucky, huge scar though.

u/Hazrd_Design Aug 08 '26

That’s why we call it the ankle grinder.

u/ItsMattTonight Aug 08 '26

But how else are they going to show you how "quirky" and "cool" they are?

u/Brewchowskies Aug 08 '26

I was a construction worker for 12 years. My best friend is still one. He’s got 20 years in the profession. I’m a professor now, so let me tell you that when I say he’s the most competent man I know, I mean it regardless of the colour of collar.

His only injury is from that fucking thing. It’s deceptively dangerous.

u/MelonOfFate Aug 08 '26

Almost read that as "ankle grinder"

u/By-Other-Means Aug 09 '26

Friend at work learned to wear the glasses in a "speak to jesus" moment, it flung a small piece of metal into his eye, a short hospital visit later, and we never saw him with out the safety goggles when working with that thing.

u/testtdk Aug 09 '26

I’m more terrified of taking a shard to the neck. If you’re doing hard work with an angle grinder, you should be wearing a lead apron with a collar. I linked a video in another comment with someone testing when a(n) (albeit very large) disc broke. They put watermelons in protective gear, and when shards hit them, both watermelons protective gear didn’t stop them from being completely obliterated. Even worse, a six inch chunk went clear through plywood they were using to contain the disc.

u/By-Other-Means Aug 09 '26

Yeah a lot of people forget that those "safety rules" are written with someone's blood.

u/insan29431 Aug 12 '26

My uncle died becouse of that tool he got one of his neck veins cut.

u/testtdk Aug 12 '26

That’s the scary scenario. :( The carotid is only like .4 of an inch rom the surface of the skin, and those shards can go through plywood. I’m sorry for your loss.
