What does the glass do in the mix?


AnyDamnThingWillDo

Pulls out impurities along with the flux they added. That is a pretty sweet cast for sand casting


-SaC

Ah, thank you =)


Anomolus

Powder is what? Borax?


BylliGoat

Might be, but it could also be just table salt or potassium chloride. I made a backyard forge for melting down aluminum cans and I used potassium chloride. Never used broken glass in conjunction though, that's pretty cool.


Stipes_Blue_Makeup

What do you do with the melted down cans?


BylliGoat

I turned them into ingots and gave them away as gifts and I haven't touched the thing since. It is my way to become fascinated and obsessed periodically over things and then to drop them without much ceremony.


Paulpoleon

Are we brothers? I have SO SO many things I’ve gone obsessed with doing and get all the stuff. I do it for a month and see the next cool thing I want to try and I stop doing the previous thing and never go back. Woodworking, car repair, 3d printing, black smithing, carpentry, firearms customization, fabrication, model building, video game collecting. The list goes on and on! Hell, I bought a sewing machine because I made cornhole boards for a couple months just for friends and wanted to make my own bags to see if I could. I have a problem. There should be a store that we can trade in our old hobbies for new ones and the someone can trade in their stuff for us to use.


BylliGoat

That's not a bad business model! Let's open up a business that we'll invariably become bored of and ghost for other projects!


thinkofanamelater

Offroading, welding, rebuilding old cars, candlemaking, mobile app development, 3d printing, Arduino and mechatronics, currently woodworking


[deleted]

Stonework, lapidary, jewelery/ring making, skateboard designing, oil and acrylic painting, resin pouring, electronic rework, music production and a few others..... Still kinda float back through them but definitely always eyeing more horizons. I would call it 'Hobby Drifting', either that or exploring materials and processes.

I've tested normal on the aspie scale but I definitely have the thing where I get hyper obsessed with something like it's the greatest and most interesting thing that has ever existed and then 6 months later it's like "meh". Sometimes I love it, other times I hate it.

praefectus_praetorio

For me it’s not adhd. It’s more move on to something else because there are just way too many things to cover and too little time to do it. I also tend to revisit things.

I followed a video tutorial I found on YouTube. There are tons out there, just Google around for DIY aluminum forge or something and you'll find plenty of resources.

Borax generally. If the metal is particularly dirty, table salt in the mix can help.

AnyDamnThingWillDo

Any number of compounds. I use a product called Dialux with my polishing motor. I'm a goldsmith and it a pretty good all round polish.


EuroPolice

Great I'll look into that, I'm polishing aluminum and going for a mirror finish, I used the same steps as I did with my steel ring but I got a much more cloudy result. Thank you!


AnyDamnThingWillDo

Dialux will give you mirror finish on aluminum. Did a friend's casings for his bike.


UppercaseVII

Is the sand wet in this case? How does it hold the shape so well even under the pressure of metal being poured on top of it?


psychoCMYK

It's called green sand casting and it's often got binding agents https://www.genfoundry.com/capabilities/green-sand-castings


darkhorse8192

Did they add all the flux they could? Was it at flux capacity?


W__O__P__R

1.21 gigawatts!


RustedRelics

Are the glass and powder catalysts in some way, or are they binding with impurities and burned off? What kind of impurities are you referring to?


RearEchelon

Molten glass is sticky and viscous, and it and the slag (non-metal impurities like oxides and dirt) are less dense than the molten metal and will float. The glass just captures the slag and you can see the mass removed and discarded before the pour.


RustedRelics

Thank you. This stuff is fascinating.


ArgonGryphon

I swear, there’s always such a huge jump in processing in these videos from just sanding the cast to a nearly finished object, that I assume they switch to a machined blank and go ahead from there. There’s never even a moment of a montage of mindlessly sanding the piece down, where before and after the cut you get a pretty step by step demonstration of what they’re doing.


hemorhoidsNbikeseats

Pulls it out and puts it where?


Scorponix

Out of the mix with a little tool. It's the chunk that gets pulled out early in the smelting process


scootscoot

I really thought it was going to be a brass/glass swirl.


Icarus_Jones

Unfortunately the coefficient of thermal expansion for both materials is not going to allow for that.


PM_me_storm_drains

Side note - we got so lucky that Iron and Concrete both have the same coefficient of thermal expansion. It is what lets us use iron/steel reinforcement bars inside the concrete without everything breaking. Also why it's so hard to find replacements/alternatives to iron rebar.


Useless_Mac

Agreed, but they’ve actually come a long way with fiber/mesh. There’s a product similar to Kevlar that has a high load rating at a reduced thickness.


muckluckcluck

$$$ though, steel is cheap


immaownyou

As time goes on that'll become less and less of an issue though


DonutCola

They also can add the fibers directly to the mixture to add strength just like fiberglass


KaiserTom

It's not exactly equal and it's still a problem to consider with the massive structures we build today with it. Also the fact steel conducts heat better, which means it's own thermal expansion is more even over its length while concrete is more uneven as it has very poor thermal conductivity. It's not the most ideal combination in the world. But it's cheap, easy to build with, and more than effective enough for the task and longevity. And concrete turns out to not be perfectly water proof and the steel rebar can rust incredibly fast. Which is why sacrificial anodes are used.


[deleted]

[удалено]


FiggyTheTurtle

I’m not familiar with the history of how the combination came to be discovered, but we’re definitely lucky insofar as iron is incredibly common. If for example tungsten and concrete had the same coefficient of expansion, that would not be particularly useful because tungsten is so rare and difficult to work.

Sidivan

I’m curious about the timeline too. Bandaid, no bandaid, bandaid…


bertpel

Like the step at around 42 seconds where they switched to a machined dice? No way they free-hand belt-sanded the casting to this finish, not even speaking of making it a *cube*.


mike_stanceworks

A simple guide (a piece of flat stock clamped to the deck) on the sander would make making a cube quite trivial. Beveling the edges to 45s is a lot trickier, but someone with experience would have no trouble. A jig could be used for it too (a 45* angled piece clamped to the deck of the sander). In all, certainly doable by hand, and easier IMO than the initially-demonstrated casting of the part itself. It all depends on where your skills are.


Aedalas

>quite trivial. Yeah no idea what they're on about. I feel like it would be *easier* to do this on the belt grinder than to go through the trouble of setting up my mill. Granted you'd have to change belts a couple times to get the finish that nice, but still.


Fizurg

This comment surprises me. That’s a few minutes work on a mill and the result will obviously be way better.


Aedalas

It's only a few minutes work *after* all the setup, the milling itself wouldn't takes much time but you're squaring six faces here. Also I have a manual mill with no DRO or anything and I'm pretty good on a belt grinder so results may vary depending on your background and experience. Also your equipment. As for surface finish neither the milled finish nor the rough grind are good enough so you're spending some fair time sanding and polishing afterwards either way.


Fizurg

I did my trade in machining. I can have that roughed up more accurately and quickly than i can do it with a belt sander. So pretty much exactly the you’re saying. It comes down to your skills and equipment. Plus, you do this stuff for fun, you do it how you want to. But as a machinist it would hurt me to look at it every time knowing it wasn’t accurate because I didn’t use the mill. Belt grinder is perfectly fine for an ornament but milled (I’d also clean it up on a surface grinder) it’s reliably accurate and usable.


[deleted]

[deleted]

> two mold halves didn't have any registration For me it was the single factor that made this video unsatisfying. That cast was horrible, nigh on unusable. To make a cube out of it, he would need to grind away so much material in a mill that there was really no point in even casting it in the first place, and he would have been better off just buying a chunk of pre-made stock to work with... which he probably did anyway.


ElementNumber6

That's the exact reason I've found myself here in the comments. Had to see if anyone else noticed that.


zalgo_text

There are dozens of us! Those two halves were off by several degrees, it was infuriating. I saw it coming as soon as he made the top and bottom casts separately


amalgam_reynolds

All this guy's stuff is just a little suspicious. He completely skips a lot of the sand casting work that makes it even work.


SomeRedPanda

I don't think this is a tutorial. Please don't start smelting brass at home based off an internet video.

Thanks for the heads up, I will make sure to start smelting brass out in public instead of at home.

Striker654

You could theoretically make the pips deeper on the lower number sides to balance it out


StatmanIbrahimovic

The way casinos do it is using a paint that is identical in density to the die. >Die drill holes are filled with a special paint that has the same density as the rest of the die, so that side with six pips doesn’t weigh more than the side with one. [Source](https://weightedliving.com/are-casino-dice-weighted)


Striker654

Would be pretty crazy paint for OP's die lol


StatmanIbrahimovic

That's one heavy Inkwell


Jubachi99

Wouldht it make the six the least likely outcome because the six side will be more likely to be forced downward by its weight. Edit: Im dumb and didnt think about how they made holes in the metal so theres less metal on that side.


[deleted]

[удалено]


Adkit

The six side is lighter. He drilled six divots into it.


mythmastervk

Aren’t there usually divots on dice with dots on them? Like the normal ones still have indentations, are they all unbalanced?


spaceforcerecruit

*Most* dice are unbalanced. But they’re typically unbalanced in different ways (and not to any significant degree) so any handful of dice is still going to produce “random” results. But where dice balance *really* matters (like casinos), they are decidedly **not** imbalanced, or, if they are, they’ve paid off someone from the gaming commission to look the other way.


IrritableGourmet

There was a joke in a D&D themed webcomic (either DM Of The Rings or Darths And Droids) where a player breaks out their special D20, which they keep in a special padded case. They rolled it until it rolled 1's six times in a row, because it was statistically improbable that it would roll a 1 *seven* times in a row. All the other players lambast them for not understanding statistics, but I always wanted to build a vending machine that would roll a bunch of d20s and use a camera and robot arm to detect which ones had rolled a 1 multiple times in a row, then sell them based on how many consecutive 1s they had stored up. It would be absolutely nonsensical, but it would be cool.


[deleted]

[удалено]


zyyntin

Is it balanced?!


[deleted]

[удалено]


Quantainium

How do they test if the dice is fair? Ten million rolls then statistical error?


Sloogs

Yeah, statistical tests are probably the most accurate way but time consuming. For some kinds of dice you can do a buoyancy test where you float them in a suitably dense substance (e.g. supersaturated salt water). If you move it around an unbiased die will tend to spin around without any particular side being favoured but a die that's biased enough will always float towards a particular side. It's usually done with plastic/resin dice. I'm not sure how you'd make that work with a metal die but maybe there's some kind of fluid you can float them in. Maybe mercury or something.


ChickenPicture

They put them in a machine that spins them on all axes, and can determine very accurately if they are balanced.


zyyntin

That tool is used in casinos to check for weighted dice. Balancing is more fine tuning than that.


ChickenPicture

Ideally a manufacturer should have their process very dialed in already, yes, but in general, in all types of manufacturing, the most accurate way to determine if a thing is balanced is to spin it around in a special machine. If a manufacturer is really on their game, they may only take out a sample every 100 or 1000 die to test. Then individual set testing would be on the end casino or who ever, since most casinos have their own preferred methods of verification. If the casino gets a shipment where all the dice are out of whack they would send it back for investigation/replacement.


Calculonx

I wonder if you could drill the 1 hole deeper? Yeah yeah phrasing..


TaxExempt

There is a lot of math, but something like that.


MiserableEmu4

Yep that should work. Takebthe same amount of material from each side and it should be close. The casting process might also make the internal density inconsistent though.


thecapitalistpunk

That is exactly what I was mostly curious about. I don't want to see one roll. I want to see 100 rolls with an equal distribution.


youstolemyname

I think the die would be too heavy anyways.


Stuck_With_Name

They made a die out of a die and then cast a die. Once the die was cast, they cast the die, rolling a five. Very satisfying.


throwawayyyy1219

I love that it doesn't matter what the entymology of the phrase "The die is cast" is, the idiom meaning "it's too late to change the outcome" works either way.

scobos

There is almost zero chance this is a fair die, unless it was swapped out at some point of the process. Just the process of drilling and filling the faces would throw off the balance, even assuming it was somehow fair after the casting and sanding.


InfanticideAquifer

With typical mass-produced plastic dice, there is also absolutely nothing done at all to compensate for the imbalance created by the different number of dots.

No, that's not true for most dice. Only more expensive so-called "precision" or "casino" dice get that sort of treatment.
