Yeah I've kinda lost interest in savaging batteries.

I've got eight pounds of Zamak 2 but I'm not sure what to do with it. I'm told that it doesn't melt hot enough to thermally shock the investment so if I want to make a rock with a nickel center I should try treating this shit like bronze and see what happens.

Yeah, foundry guys and machine shop guys have the stories that you don't wanna hear too much. half the machine shop stuff you can't watch because it trips Youtube's gore filter. Jewelers can't really compete but they can try; the kilns at my program didn't have peep holes because my instructor had someone in her grad program who peered through it while she shut the door, thereby puffing a couple liters of 1400 degree air right at her cornea.

Autoplay on myfordboy is like a japanese meditation.

"giant column of flame" is a good thing to avoid in casting. Some might even call it a warning sign.

There's a guy on Youtube going by "myfordboy" who is like the Bob Ross of casting. His shit is so zen to watch.

Melting stuff is easy. You need flame. Youtube thinks the way to melt stuff is put stuff in a stainless steel pan, put it on the stove and hit it with a blowtorch. Youtube is stupid. I'm fond of crappy Chinese melting furnaces that are ripoffs of crappy Italian melting furnaces that cost 4x as much. There are no non-crappy melting furnaces for less than $5k so the $250 one gets my vote.

The "and solidify it in an aesthetically-pleasing and mechanically-useful shape" is where the artistry comes in. What we're tooled up for is called investment casting. You start by making your thingy out of wax or, in this case, stereolithography resin that burns away without ash. You goop it with wax onto the end of the rubber cap shown on the bottom of this thing:

You then fill it with "investment" which is basically special plaster with some extremely fine porosity. You suck all the air out of it using this thing:

Then you pour the investment in, suck the air out of it again, let that harden and take the rubber bit off and put it in this thing:

You then program a "burnout schedule" that heats it up at the right speed to turn the resin into ash while leaving the investment magically delicious. Then after the 12 hours or whatever that takes you heat up your melter, add your metal, pull your drain plug back out, put it in the other hole of the casting machine, suck vacuum on it and add your metal. You let it stop glowing, then you pull the whole thing out and put it in a bucket of water, which causes a thermal shock to knock the plaster to bits.

That will be the next step.

Been busy.

So a casting furnace uses about 1400W (1450 according to the kill-a-watt). An enameling kiln uses about 1600W. I don't know what the vacuum investment machine uses because 3000W/110V=27A which is more than household wiring or a 110V circuit breaker can handle so it's time to get medieval on it.

Fortunately we're in the garage and all the romex is surface in here anyway so we'll just continue a trend.

Pretty? No. Done in 3 hours? Yes.

There was a lull while I talked to my brother-in-law the electrician because those are 400A cables direct from the box with no way to turn things off. But the "mains", which are a pair of 30A breakers just sorta slapped in the middle of the box, do work as "mains" presuming you don't need to turn off the "furnace" (whose wires go nowhere ever since this place was switched from fuel oil) or "water heater" (which has long since been replaced with gas). So really what I've got is 60A service to the house, then unholy mother-of-god cables from the meter to the box, then I'm really only using half of the box which is okay 'cuz I've got like 12 slots to slap breakers in. But it was... dicey for a minute there.

MOAR POWWWWWAAAAAHHHHH

Worthy of note: I started with 100 feet of romex and this is what was left. Cut that shit close. Actually wouldn't have made it if I came through the bottom of the box rather than the top. So now I've got a handful of 12/2 scraps, 4 shiny new outlets, 3 shiny new circuits and a melting furnace I haven't used yet. Hmmmm....

So the way you make casting grain is by melting your shit, raising the flask to a reasonable height and then dropping molten whatever through water so that it turns to globules of glorious roundness before it hits the bottom, which is steel. Some of us have 1L vases.

I sent a picture of this to my buddy when he asked if I had a 20gal steel bucket. I sent him this said "no LOL but I'm bored." He responded with "be sure to film it because it's going to explode LOL"

"R U HAPPI NAU"

"Fill it up to the top"

So this is an after-shot because I'm not stupid enough to film molten metal with one hand and pour it with the other. Interesting discoveries: (1) Borax ignites in a burst of flame when you sprinkle it, causing you to spill (2) a carbon crucible raised to 1085c glows read-by-the-light-of-it orange (3) the difference between "not pouring" and "dumping immediately to the ground" is about 1 degree of tilt. But hey, when you're done?

114g of 99.95% copper! My buddy suggested that if I was feeling bold I could savage some old batteries for the zinc, melt it down and cast my own brass. I also didn't take any pictures of the excitement associated with savaging Costco AA batts for their zinc; suffice it to say that there was enough sparks, inadvertent heat and spitting electrolytes that I opted out. I did recall, however, that I had a fair amount of useless sterling scrap and my buddy has done a lot with shibuichi so let's melt some more stuff!

I'm prolly gonna calculate how much 90/10 shibuichi I can make with what I have on hand and get goofy with it. I figure this casting won't need supporting, has limited surface detail and will take on a wicked cool patina if I cook it right and what I'll be left with is an awesome little keychain-sized keepsake to embolden me before emarking on bigger, badder stuff.

'cuz the real problem is a principle consumable in 3D printing is 99% isopropyl alcohol. Since I don't know when that shit will be available again, I'm having to be creative but this one? This one I think I need to do.

Because reasons.

"There are a bunch of books about these guys but they're expensive and in German so I didn't read them."

Here's all you need to know about Yello. Dieter Meier grew up amongst the gnomes of Zurich and never didn't have money. Right about the time Van Halen was blowing up they decided to head out to Hollywood, where they spent a lot of money on other musicians. As a consequence Dieter became sort of a Swiss Bob Geldof in that there was no obvious reason for him to play Pink in The Wall and no obvious reason why he could launch something like Live Aid other than that Henry Kissinger is far more important as a guy who knows diplomats than as a diplomat himself thus did Yello get heard by everyone who is anyone and some of it trickled down to you, the proles.

There are two structures in music: there's the stuff the creatives listen to and there's the stuff you listen to. Massive Attack is the ad creative's Fleetwood Mac. Sometimes it escapes into the normie world. Yello was the vehicle by which a self-supported rich AF Swiss artist exposed himself to the American creative class and that's why he's still got one of the biggest studios in LA which is open by invitation only.

kingmudsy running late with the craftthreads I see.

Nice desk. What it needs is a bunch of stickers because you know you aren't going to want it once this thing is over. Improvisational furniture requires improvisational decoration.

kleinbl00  ·  1 day ago  ·  link  ·    ·  parent  ·  post: The free market and small gov't aren't really going too swell, huh

You know what? I'll play. Because it's illustrative and gets more to the core problem here.

Jared Dillian pointed out on Twitter that it isn't capitalism if the failures aren't allowed to go bankrupt. Pithy. But here's Matt Levine in Bloomberg:

    The ordinary reaction, for a company that doesn’t make stuff or earn any money, is to go out of business and lay off all of its workers, but it is pretty widely recognized that that would not be a good reaction, for most businesses, right now. Your favorite local restaurant’s revenue has not gone to zero because its food was bad, or because it failed to innovate to keep up with changing tastes or whatever. Its revenue has gone to zero because a plague has caused governments everywhere to prohibit eating in restaurants, we hope temporarily.

The LIBERTARIAN viewpoint is that businesses should choose their risk level, customers should choose their risk level and the government should stay the fuck out of it. The CAPITALIST argument is that the most successful businesses will have amassed a stockpile of money and supplies to ride this out because they have demonstrated themselves to be the most adroit at navigating unforseen crises. The problem here is that the invisible hand of the marketplace isn't being permitted to shake the tree enough.

Unfortunately we've seen what libertarian economies do during pandemics.

And I mean, if you ask Barron's, they'll point out that the Black Death of 1349 was the second worst economic shock in 800 years of history after the prorogation of parliament in 1629). So really, a third of the population dying did less damage than eliminating the mechanism by which taxes could be raised for ten years. Now that's an anti-libertarian argument! But the real problem here isn't capitalism, isn't socialism, isn't libertarianism, isn't AOCism or whatever, it's corruption.

And the longer I spend looking at this stuff, the more I'm coming around to the idea that it isn't so much the rules that you follow, it's whether or not you follow them. I mean, the "free market" can't even compete if FEMA is just gonna seize ventilators:

I don't think society is particularly fragile. The opposite in fact. I think society has pretended that things are normal and unchanged for the sake of its own mental health while the oligarchs and the sociopaths take over. I mean what if I told you a standing US Senator took the advice of a classified briefing and dumped all her travel stock while publicly proclaiming for a month that nobody had anything to do with it? That's Michael Bay shit right there. Dr. Evil crap. But here in The Darkest Timeline not only did she do it at least twice, she did it while being married to the CEO of the New York Stock Exchange and she isn't even the only one.

You can't really bitch about one person's philosophy over the other if the rules we all agreed to aren't being followed.

Washington is the most aggressively regressive state there is. There is no state income tax. Not only that, but city taxes are all consumption based, too. The birth center's city taxed us on the computer equipment we bought even though we didn't buy it in the city.

What will blow your mind is that the state taxes are actually less than California's, and California also has about a 10-12% income tax, yet California's services are a good order of magnitude worse than Washington's because most of the money just goes to graft and corruption. They literally have double the budget per person and provide about a third of the services or less. My unemployment benefits in WA state are more than double what they are in CA.

Wanna see a video of the surgeon general turning a t-shirt and rubber bands into PPE?

Public health measures are always reductive. I mean, we're at "yeah we know we told you to stop asking for masks because they don't do anything that was mostly because we want the doctors to have them more but actually Jared Kushner has been hoarding them in a warehouse and seizing shipments going to states because he's an asshole so I guess yeah wrap your fucking underwear around your head."

"All models are wrong but some are useful." - George Box

The takeaway is not "everyone who works in healthcare is fucked" the takeaway is the model we have for aerosolized epidemiological spread is not 100% correct. I mean, biosafety levels are based more on how nasty stuff is than how contagious it is. So while the dual respiratory model isn't a great curve fit, if the goal is to minimize infection it works.

If instead the goal is "never get personally infected" then you're looking at a moon suit anyway.

I said Los Angeles and Phoenix.

My beef with the prior post is the argument that only the South understands true suffering (wraps self in confederate flag) and fuck him, fuck you and fuck anyone else that thinks that poverty in fucking Tennessee is somehow more poor than poverty in fucking east LA.

Thunderously high taxes, I think. This is what happens when your government's entire tax base comes from use taxes.

We're at $2.98 and we're fucking surrounded by refineries.

Between me and my mother in law we spent maybe five hours trying to get tested. Neither of us succeeded.

I've never even heard of someone in the US getting tested twice.

kleinbl00  ·  3 days ago  ·  link  ·    ·  parent  ·  post: Maybe We Should Have Let the South Secede

    I live in a major city in Georgia (not Atlanta). The nearest Wal-Mart is a 12 mile drive, and I have one Food Lion between me and it.

I have experienced the exact same thing in Los Angeles and Phoenix. None of which shows up on this magical map. The NYT has data for "more travel" and "less travel" but when you dig into the numbers, "less travel" for Seattle" is from "miles" to "feet" whereas in Daytona Beach "less travel" is a 50% reduction.

The South loves to pretend that The South is special but The South is just more pugnacious than everyone else because they lost.

Britain and France would have gone all in on the Confederate States of America and favored them heavily with trade. Britain was wholly dependent on the South for cotton and desperately wanted to trade with the Confederates if it weren't for American threat of war. Shit got dicey.

If England and France had gotten their shit together the Confederate States of America would have had millions of British troops in it, with still more in Canada, and British and French blockades of American ports. The United States might have fallen, or at least been reduced to an angry, defiant and violent backwater like Northern Ireland in the Troubles. The Confederate States of America would meanwhile have been an ugly-ass version of Jamaica where slavery was never banned. With a united England and France intent to quell the colonies, Mexico would probably still be French.

It's pretty appalling, sure. And the South is nearly always embarrassing. But the stakes were dire.

"Art is making something from nothing and selling it."

kleinbl00  ·  4 days ago  ·  link  ·    ·  parent  ·  post: Coronavirus Is Bringing Back the Forgotten Tech Trends of 2012

Simply put? The FDA.

The thermometers you're talking about are thermocouples. Thermocouples aren't crazy hard - you can get really precise ones for not a shit-ton of money. But then you have to get them FDA qualified and if it's something that can go in an orifice - any orifice - it's in FDA hell-world. So you take a $1 thermocouple, a 50 cent display board and a 20 cent plastic body and it's suddenly a $30 digital thermometer because $26 of that is the paperwork and testing necessary to get it FDA-approved as a healthcare product.

If you go with a not-stick-it-in-a-hole thermometer you capture more of the raw technology and less of the regulatory oversight. Sterilization and contamination protocols for a contact medical device are substantially more chill than for anything you put in your body.

I've got a Thermoworks Thermapen. It'll read to a tenth of a degree in half a second with a NIST certification but it's not healthcare approved. We use that exergen jobby for the kid; you gotta swipe your forehead like six times and take the highest number.

    Bloomberg News reports the figure far surpassed analysts’ estimates, which had a median of 3.76 million. The department also revised the numbers it reported last Thursday for those newly out of work, to 3.31 million. The new figures may not be a full picture, however: Several states have had their unemployment filing systems crash under the new heavy demands.

WA state is telling sole proprietors and freelancers that esd.wa.gov will not be able to support their claims until April 15 at least.

I have eleven linear inches of screenplays that were represented by William Morris. I have album credits older than you. Don't fucking lecture me.

You're exemplifying exactly why artists are so fucking tedious. You've injected a value judgement into someone's spare time. I've been there: when I was stressed out what I wanted to do more than any goddamn thing in the world was kick back and play The Sims or some shit but no, I wrote screenplays. Because Art. Yeah I heard you even though you didn't say it - "screenplays aren't art." Because "art" is this thing that you do, and people you respect do, and everyone else is wasting their time. "I make music because I fucking need to." Get over yourself. You make music because you think it sets you apart from all the people around you, who you hate, so you're grabbing at the one thing that in your judgment separates you from them and if you don't think everyone else doesn't see it you're fucking delusional.

Look. Make art. Make art because it's therapeutic, make art because it inspires you, make art because it defines who you are but stop shitting on people who aren't making art because what it does?

Is it makes the people around you hate your fucking art.

Right now? Right now you're telling yourself I'm not really an artist. Because I don't "fucking need to." Listen up: Every external observer is aware that the doubt you feel about your abilities and the uncertainty you feel about your path is expressed as vitriolic backlash against everyone who makes a different choice than you. And it is winning you no friends. And until you've seen a line 400-long full of assholes just like you with even less likelihood of going anywhere with it you will hold tight to your bosom the idea that somehow you're special so you get to be an asshole about it.

Ableton is just another video game, son, and a guitar is functionally a skateboard.

    Hey man, I don't make music because I want to. I make music because I fucking need to.

And your brother fucking needs to play League of Legends. Get the fuck over yourself.

I think there's a lack of context at play as well. WHY. WHY does the world need your album. What is your album's place in the world when you don't know what the future looks like.

Social media is performative. Never has that been more clear than in the Facebook group for my kid's school. The same parents whose kids interrupt every.single.thing are the ones posting pictures of their kids' learning stations, their projects, their cute little sketches... it's like "bitch if you just hung out with your kid for fifteen minutes my kid could actually get through Spanish but instead you're on Facebook posting pictures of her interrupting the class to show how on top of it you are."

They aren't on top of it, and they know it. What they want is a dozen likes and comments telling them they're on top of it because clap your hands if you believe in fairies.
