Practice with the addition of sodium silicate to sand using CO2 to set, this served two functions, the first being to get some practice with the media the second was to find suitable ratios for the mixture.
Yeah, the real question is how do you say Titanium? TiTANyum. Who talks funny now?!? Unmistakable voice of Geographics in the bg, nice. I love English units for measuring, fractional measure is boss for carpentry, but as soon as it comes time to do power and energy, I switch to Metric. And I say this as an engineer who once had to give a lecture to other engineers on the misuse of mass in energy measurements due to unit system conflict. One guess why I had to do that, and if you didn't guess that it was because I made a dumb mistake on a calculation, you guess wrong. Fantastic job for an early effort casting, and a solid science video!! Well done.
How big was the balls up? As bad at the mars orbiter or did you just end up with a 2' long aircraft carrier that came in under budget for once? I appreciate a good bit of regional dialect, variety being the spice of life an all, but I spend my life with my nose in american service manuals, american predictive text and I'm hideously dislecsic, every time I spell carburetor it's different....
@@turboconqueringmegaeagle9006 Let's just say the pipes were VERY corrosion protected, but I actually referenced the Mars Orbiter in my talk. Language, dialect, colloquialisms, slang; it's how we monkeys identify the other monkeys in our own little band. Honestly, I love language because it's the thing that makes us human, no matter what version of it we speak.
Great first try. I've seen some people take a bake bean tin and cut both ends off, fill with sand and bore a hole straight through as an extension to the feed hole. I assume to add pressure to the feed. Might add definition to your moulding. Definitely learned a lot from this video. Happy new year.
You've got to tell me specifically what you like or dislike about mi vidys mate, to me they all feel the same, only thing different with this was the over lay of the pattern making, was that good?
you probably dont care at all but does anyone know a trick to get back into an instagram account? I was stupid lost the login password. I would love any tricks you can offer me.
@Westin Jerome i really appreciate your reply. I got to the site through google and I'm in the hacking process atm. Takes a while so I will get back to you later when my account password hopefully is recovered.
There's a good video using molasses for this.... sand casting in Nepal wondered if you've tried molasses. I used Molasses for a paint like coating over dirt and sand to make a silicone mold. Steph Harden surface very well for a few days and washed away from the silicone ones finished really good stuff using in that format. Some of these countries with little to work with often have great ideas or go around the fancy stuff we have at hand. love your work man
It's really impressive watching those chaps work, I'm not sure I've seen one using molasses, old engine oil is quite commonly used too. I watch a bit of "Pakistani truck" when I get the chance, you might enjoy their channel for the levels of ingenuity.
Good work. You didn't put enough CO2 in the cope, which is why it might have wanted to slip out of the cope. You can put a little bead inside the cope and drag to give the sand something to grip onto though. The mixture you ended up using was 10ml of 20% mixed with 225 grams, or 6.2% by weight. Amazon has 40% Sodium silicate available at £14.99 plus a fiver delivery, or 20 litres for £34.99 plus £9.50 delivery. (£4 a litre or £2.25 a litre).
Just the lack of a key that lead to it slipping out, I'll make sure future flasks have a baton, there was also a bit of adhesion to the cope so I think talk might not be the best parting agent but anything oil based is likely to explode when I pour. Very helpful with the Amazon prices thanks.
Did you add anything to the ally? I was told to add silica or atleast copper to stop shrinkage and help with machinability. I want to cast some stock for machining but I was told that just straight melted ally cans is kinda crap. But that looked good
Low sodium salt works as a flux for ally and should bring most of the muck to the top but what you really need for dirty metal like cans is a de-gassing tablet, I've never heard of any diy hack cheap version. Imo cans are not really worth the hassle I use other castings to cast with, extrusions are good too but when you use stuff that has a lot of impurities it makes bad castings.
If I ever get round to doing something that requires cores, I'd probably double the quantity! You'd always need far less than the main flask, and you don't need the porosity to let the air escape either, just strength.
It does gasless mig fine, not used it for anything else yet. It's pretty solid which is nice, reassuringly heavy and spares are available which was my main concern.
Great stuff for a last resort to a cracked engine block. Just get the engine block water hot by trickling water in the radiator as it leaks out @ the hairline crack & just pour a dissolved pint of it in the radiator a little at a time till the crack seals up. Downside... the block must be drained before every forecasted freeze; cause antifreeze seems to dissolve it at the crack.
That's very interesting, I'd heard it could be used as a short term fix for a head gasket, was unaware it didn't like antifreeze though. Take care my friend.
I'll do it soon but have already made up my mind re. It's properties. My crucible and foundry probably won't enjoy those temperatures so I'll let you decide, do you want to see wolf man's alloy first or mild steel in place of the iron, because personally I think the iron with its high carbon content will cause problems with the aluminium.
@@turboconqueringmegaeagle9006 Iron is Iron steel is an alloy of Iron and Carbon so I don't understand what you mean by carbon in the Iron. of course, I was just a builder not a metalworking bloke like you, and it wasn't Wolfman's alloy it was a bloke called metelcast something or other and it originated with an Italian metallurgist, I posted both of the forgers Wolfman was th second to cast it.
@@nigelpalmer9248 it's kind of the other way around but not, when sciencey folk talk about iron they mean elemental iron, when anyone else talks about iron it's got a carbon content so high it's more of a mixture than a compound ie. You can see the carbon in the metal, steel takes that grey iron and purifies it by burning the excess carbon away with oxygen to a point where the small amount of remaining carbon is properly held in suspension. From what I can see, the copper, aluminum, iron alloy has no carbon when used in industry, but if you wanted me to produce and test what mr wolf made it would have a fair amount of carbon in it because he used cast iron brake rotors.
