here we come this video is brought to you by the volta 2.0 a universal reliable fast charging magnetic cable that works across all usb devices including with data transfer capabilities check it out today at the link in the video description let's take a moment to appreciate just how challenging this is going to be by cracking open this pulse red xbox series x controller starting with the battery cover i guess for disassembly we pry off the outer shell starting with these hand grips at the back and then remove all the screws including ah yes this sneaky little boy under the sticker here my warranty is now void i think hello ah wow that is a complicated part if we want the functionality of the finished controller to be exactly the same though we are going to have to recreate this one for one and that won't be easy thin components particularly ones with lots of intricate detail are especially difficult to cast that's why we won't be attempting this here in our own shop which brings us to expert castings here in beautiful downtown vancouver but as grand as the entryway looks things are about to get down and dirty unlike ourselves expert castings are just that experts with accolades like being one of two places in canada that can work on a tiffany piece and making jewelry for disney 50 shades of grey once upon a time and many more now they first tried to convince us to cast our piece in bronze then gold played it this is generally what's done for movie props like this one right here it's way cheaper and usually gives a better result anyway but problem is this was one of those videos where we came up with the title first and then figured out how to fill in the gaps later so we were stuck cutting a fat order of pure gold to the royal canadian mint they just brought this over and look at it we have one kilogram of gold right here so this is a professional engineer's salary in my hands and it's shocking how heavy it is given like the size i'm surprised how small it is look at this thing forecasting you first have to create a negative of the shape that you want for the metal to be poured into adam is going to be taking care of this step called spruing wax gets heated up by a low temperature soldering iron and stuck to parts of our controller this will create pathways for the gold to pour into in the past rings would be painstakingly hand carved out of wax but now most parts are just 3d printed some parts they cast all the time like this anchor so for that they've created a negative that they can inject wax into using this wax pot all of the pieces on the sprue need to be organized kind of like an upside down tree this shape makes it easier for the molten metal to flow into the cavities while also making it easier for air to find its way out that's critical because it's super important to accurately weigh the plastic and the wax on the sprue and use the density of those materials compared to gold to figure out how much metal will be needed to fill the mold too little metal and there won't be enough force pushing down into the mold or it might just not fill at all and too much metal well that's just wasteful and that's very expensive waste now we need to create the investment which will harden around our sprue simply add a .395 ratio of water to plaster powder in a large bowl and then combine with a kitchen mixer for two minutes place the mixture under vacuum for one minute 40 seconds to remove bubbles pour the plaster into the mold and place under vacuum again for another minute and 40 seconds from here the whole thing is placed in the kiln at 700 degrees celsius overnight this will give the wax and plastic time to melt and then burn off leaving only voids behind now we're basically ready to melt the gold but there's one problem our hunk of gold is too big if it makes you feel any better this is much more painful for me to watch than it is for you so if you could go to lttstore.com right now to ease the pain that'd be great thanks now you guys might have guessed that during this chopping process tiny flakes of gold will fall off it's not too bad the flakes coming off of our piece here total only about 10 to 20 cents but they do add up they actually sweep the floor here and the benches every day chuck it in this big bucket and in a year it can catch about a hundred thousand dollars in tiny pieces of gold our second problem is that the royal canadian mint is awesome and their four nines gold bars are just too pure but okay seriously though even pleb american us mint gold would be much too ductile for actual use in fact oh yeah it's so soft that it would probably deform in your hands the first time you got head shot by some 11 year old in call of duty so then summer here we'll be expertly creating our alloy using 450 grams of gold per 150 grams of alloy blend we're using number 220 which is 12 zinc 11.5 silver and 76.5 percent copper blends are chosen mostly for the color that they produce and ours should give us a nice orangey yellow look finally it's time to melt some metal baby using an induction oven the gold is heated up to 100 degrees celsius and our mold is then removed from the kiln at 600 degrees celsius the thing is if the mold is too cool then the gold might solidify before it fills in all the cavities before the gold can be added though all the air in the mold has to be replaced with an inert hydrogen nitrogen mixture this helps prevent the gold alloy from reacting with the air while it's molten so when everything's ready they just lift up the center column that's lined up with the center sprue of our mold and all the gold flows in is it going is it going did it go can i see it molten gold david is it good yeah oh that doesn't sound very confident we didn't put in enough gold oh the concern right now is that there's a bunch of tunnels that the gold is supposed to flow down and there's one that it didn't go down but there's like five that it did apparently that's what she was poking at she was poking to see if the tunnels were full let's see if it worked ladies and gentlemen here we go oh bomber oh wow it's heavy i guess we might not even need to worry about that though because that's covered like all of this in here you don't see well because of the uh holding it together i think it's fine actually you might be right it's actually the texture oh my god it has the texture of the xbox controller i mean i i know i shouldn't be surprised but like but it but it did it kind of looks like ass hey right like that's my ass tens of thousands of dollars and it just doesn't look like anything tens of thousands of dollars of ass of course what you saw was only the back piece of the controller so the front the shoulder and trigger buttons as well as i don't know whatever you call these back pieces and the battery cover were all done ahead of time due to size limitations so with a combination of a soap bath scrubbing with a toothbrush scraping with a pick and even some actual removal of the material this will turn in to this now this was our first cast and it was pretty good but there are some small surface finish problems once it's cleaned up we should be able to go from a more satin like finish to a super shiny one like you actually see on this corner here of course there are still some problems that we have to solve like for example what are you going to do about the parts where the sprue was joined to the original plastic i don't know but i can't wait to see if the thing actually comes together so this is it ladies and gentlemen test fit time oh that's it okay where's my uh where's my battery cover at alex can you be can you be my third hand here oh man once all the sprue crap is on there and this fits together this is gonna be crazy guys do not miss the met the next part of this and don't miss this segway to our sponsor drop.com dang guys we need that sponsor dollars like bring on the rage shadow legends no but seriously drop.com is featuring the control keyboard it's one of their top-selling keyboards with over 11 000 sold and why not it's got a solid cnc aluminum frame a built-in switch plate RGB lighting qmk firmware for excellent customizability hot swappable key switches and your choice of cherry mx kaiwa or halo switches it features a floating key design with dual usb type-c connectors and weighs 964 grams the only way it could be heavier is if they made it out of a heavier metal so check it out at the link down below if you guys enjoyed this video and you love crazy projects maybe you'd like our water cooled playstation 4. that's right we did one of those away a while back let's uh we don't have anything current gen look we're working on it okay"}
