Your nickel strips were most likely nickel coated. It is very common for nickel strips to not actually be nickel if you get them from a an unknown vendor.

This is exactly what I was thinking, it's a big problem in making DIY battery packs for Esk8, you could probably check if it's coated using a magnet. P.S. love your stuff

I know, three year old video as of my writing this, but here's an idea: 1. 3D print a mold that you can press ceramic clay into, less likely to crack than 3D printed ceramic. 2. I could see the silver paint after your copper electroplating. Probably needed more time coating, I'd also add a layer of nickel too, get it all much more solidly metal, which would add durability to your parts. 3. As for what another user suggested, coat all of the part, especially the inside, that will add greater structural support. 4. Alternatively, you could use a layer of fireplace adhesive (I forget the name, but I saw you use it) to coat the inside if you are concerned with heat resistance. I have been binging your content lately when not working on papers, it's been relaxing for me to watch you build cool stuff and cause explosions.

Try adding fuel, igniting it, and then adding oxidizer, to prevent those explosions (hard start). You were right about the accumulations inside the engine and the spark plug, but I think that your mixing also is in play here. What happens when you add oxidizer first and then fuel is you get a stoichiometric mix of fuel and oxidizer in the chamber, which detonates just like any explosive.

Just take care about the bubbling of CO2, so stirring and slow addition is necessary. After that, just boil the water and acetic acid out. 120-130 °C should work. Use an oil bath if you can. Direct heat from a heat plate could cause problems :D good luck!

[@ThomasAndersonbsf]

problem I see with this is you end up with either aerogel formation which has a much lower thermal survivability than people realize as it collapses, if you use the water and dry method you get silica gel which any water causes tiny fissures and liquid water outright causes it to split and explode like some ice cubes will when dropped in water, but for a very different reason. To get the effect he needs it needs to be held into a mold and fired to bring the SiO2 to full density, before being allowed to expand freely, for a higher temp than both of these, I would suggest sodium alumina as it will collapse if done correctly into a solid transparent aluminum ie sapphire glass, with considerably higher melting temps, so alumina aerogel will last in higher temps too if you want a good insulator to keep the heat in, tougher exterior to keep leakage from occurring and all that jaz, but honestly I would love to see him cat up all the parts and use spin friction welding with titanium wire on a dremel on sheets cut to shape and make it out of solid titanium, as he would be on course for making rockets he could launch into space and have the first tomato free satellite network ;) *there are a couple ways I have theorized to desalinate the sodium half of the silicate and alumina compounds with, with out an acid that actively pulls it free from the product leaving a pure substance against the surface, and then using laser tech to densify it, in layers, against the surface of an expanding conductive coated shape like say a round bottom flask grown around a flask shaped blown up balloon coated in graphite conductive paint to make it an electrode, that can be collapsed afterwards and withdrawn from the vessel, but it has not been tested yet.

Someone has probably already told you that copper plate is the foundation for a lot of metal plating including nickel. It looks like your copper was not covering the parts very completely though. Also the silver didn't look thick enough. I suggest more than one dip in the slip to build that up, then sinter it, then thick copper followed by thick nickel. Remember to polish the silver as much as possible, same for the copper to get better adhesion of subsequent layers. Also, of course you should look at what parts of the printed components physically blew open and make them a bit thicker. Anyway, I hope this is as much fun for you to do as it is for us to watch!

I think you should start developing a DIY metal 3D Printer and then use that to print a rocket engine. Or a beehive :D

[@Penofhell]

As I wrote in the last video, aluminium casting (sand casting with a 3d printed master, or lost PLA in plaster of Paris) could be a great and relatively easy way to make complex metal parts at home ;)

[@kadecoleman4104]

@@Penofhell I’ve wanted to sand cast aluminum parts for years now, thank god I saw your comment and reminded me. I need to go buy the materials to build the wooden boxes and sand and get other materials to build the furnace thing and make a couple crucibles! Thank you for reminding me just in time !

[@ThomasAndersonbsf]

@@Penofhell thought sure you could use powdered cat litter (the super cheap kind that is bentonite clay mostly) and really fine grained sand to make "green" sand for lost wax casting and then just heat up the thing a bit more to get PLA to burn completely away? Plaster of paris will dehydrate at 350 degrees I thought becoming brittle and powdery again? (might be wrong on the exact temp, just remember that heating to drive off the water's OH that causes it to harden allows it to be reused all over again, and aluminum has a melting temp of 660º) but the bentonite and sand should handle much higher temps than that 660 of the aluminum so it can be over heated to make sure it flows and retains a lot of its heat, (heating the mold to nearly the temp of the molten aluminum seems like a good way to ensure no blocking happens along with avoiding easy to fracture points from some areas being more annealed while others are more crystaline in nature, but aluminum is much to low of a temp for his engine, I would suggest getting a pepakura making program and import that model for the 3D printer, so it can turn it into a tuck and fold 3D object then he can make it out of stainless sheet or maybe titanium if he can get a cheap source of scrap titanium sheet metal (they do heat tests and such on batches of titanium sheet so should be able to get the off cuts they used for this, from someone who worked there and grabbed it to sell it on ebay or something like I did with .020" thick sheeting, and he sent me a sample that was like .125") if using titanium then I can say it is not that hard to use a router attachment for a dremel, and chuck up 3mm or 1/8th inch thick titanium rod that you then drop down on the seams while spinning about 15,000 to 18,000RPMs to do friction spin welding though it does take some practice, even if you are used to normal stick welding or tig welding, but the welds are a bit better than even tig based ones, and you won't need to oven temper it when done. :)

[@strictnonconformist7369]

Even more amazing is not setting his house/apartment on fire: I mean, seriously, who is having flames shoot out several feet from the back of rocket engines in their attic? Wait, who test-fires rocket engines in their attic? @integza does! He's willing to burn down the house in the name of 3D printing rockets and their test firings. If that's a rental, I have to think the landlord wouldn't want to have a tenant do this, and if this is a place he has a mortgage on, the insurance company wouldn't want this going on either (well, certainly not the bank with the mortgage, because insurance will likely deny coverage over something like this: both insane and dangerous while arguably doing business in the form of youTube video production).

[@WileHeCoyote]

INGETZGA! PLEASE! ONE MORE! Print the ceramic peices, glue them together with glaze or wire tie them together with copper or what ever you need to do, but then dip the whole thing multiple times into a proper graphite paint/ink! Then elctroplate as long as possible to get as thick as possible of a coating to make it essentially a completely encased single peice of copper with a ceramic core. @Robbertmurraysmith is always down for a fun project!

[@FzudemB]

Could also try dipping it in molten copper (if he has the possibilities for that) Or use spray welding

[@WileHeCoyote]

@@FzudemB molten copper is hard to make/sustain with out a decent homemade smelter and alot of room and lots of fuel, and its unlikely the fragile ceramic parts could handle the extreme temperature change across the part as it was dipped

[@cobberdog]

He could also first glue the parts together with slip, plug any holes in the part and then cover several times with slip and put in the furnace in between. That would create several ceramic external layers that are entirely continuous, while leaving the inner dimensions unchanged (could also coat the inside if dimensions don't matter too much). Then electroplate the whole thing.

[@dsconnectedn3uron324]

i also really think he should try the glaze, i bet he is afraid because it is glass, but once it is baked onto the ceramic it will never again come off. even if he shocks it with cold water, when it is hot ,it will only make a spiderweb of cracks in the surface but stay on the ceramic. no sharp edges, it's done in ceramic arts because it looks really cool. Also he can use glaze like a glue and bake the three parts together. He just needs some tungsten wire to keep them in position while baking them. metalplating with copper has no use in this case, because copper will grow in grainy little structures, when you electroplate, it will not become as tough as a copperplate no matter how thick. does anybody know how i can get into his discord? i have some ideas that might help him...

[@Craftlngo]

now that you have loads of these little jets, you should build a schlieren photography setup to image the shockwaves and pressure waves coming out of the nozzles.

[@joziahserrano2507]

Well, it’ll be a bit of a pain to get super sonic flow to achieve those shockwaves

[@TakeshiM]

@@joziahserrano2507 not as difficult as you might think! If you put a burst disc halfway down a pipe and pull a vacuum on one half, you can pop the disc and the air will rush into the vacuum as a Mach 1 shockwave, with an expansion fan propagating the other direction. It’ll also mean we can see how turbulent the flow coming out of the nozzle is, and if it’s over/under expanded

[@joziahserrano2507]

@@TakeshiM you’re right there but since the amount of pressure and volume being moved would be hard to discern it would be hard to replicate it for a continuously produced combustion, and wouldn’t much allow us to actually see if the flow is under or over expanded... it might be better for him to use a aerospike nozzle for now to see if he can get continuous super sonic flow, and with experimenting with that he should be able to determine the right nozzle dimensions to make a conventional delaval nozzle that can maintain supersonic flow... though I’m no rocket scientist so that everything I said with a grain of salt lol

[@TakeshiM]

@@joziahserrano2507 I've only taken one class on propulsion systems which is the real reason I want to see him do this. But in any case, schlieren photography reveals even minute changes in pressure, so it can be used for more than just finding shockwaves. He could probably even see the vortex coming out of these vortex engines if he angles it right. Also, he was getting a good few seconds of continuous operation even in these tests, and with the slow motion camera that can be stretched out even more.
