Story of my life. I've been binging through video's like this for the better part of a year now, constantly being directed towards sponsored channels (some of which are excellent though). But it's channels like this that contribute most to knowledge.
I saw your video about making cores for the AR15 rifle, sodium silicate does work but going by your ratios you used too much that is why it bubbled so much.
Agree. Also, my sodium silicate wasn't specifically made for sand casting, and might be the wrong formulation. I tried using less but it just fell apart. In the future I will get some proper sodium silicate made for the purpose.
That was unbelievable. Can't decide if when the damn first one went wrong I'd have slit my throat or just thrown it through a window. Second try was a charm ... I wouldn't have got that far. Just discovered your channel and I'm currently trying to catch up and enjoying every second.
Yet another amazing cast. I really felt the pain on the first cast! Had a few of them myself but after so much hard work you did on this one I would have cried! Keep on with the great videos.
Wow that is a challenge! Did the impeller blades have plenty of draft? That sand didn't look like it had resin in it. It must have been a very dry mix. How much time do you have to ram everything up? Really interesting video. Thanks.
Everyone on youtube saw it as well but I made another and it worked. The trouble is it is so time consuming to make the core and when it fails it has to be done again.
Thank you and all those involved in the content, contributions, efforts and production of this channel. Merry Christmas, Happy Holidays and Happy New Year to all. May the new year bring you, your families and friends much health, wealth, happiness, safety, security, appreciation, respect and peace.
Turned out really nice👍🏻👍🏻👍🏻, much much better than the impeller I tried a few years ago. I have a suggestion of you plan on making another one, at 12:00, use a torch to heat the ring and it may release better.
stunning work here. quick question for anyone though, on the first casting it looked like molten iron was droped onto the concrete? is that not an extreme hazard? i studied civil in school... and while this was never discusses, there is a phenomena called explosive spalling that i have seen personally. basically moisture in the concrete matrix is vaporized and the near surface can rupture spraying agregate and concrete. i imagine that explosion with the addition of molten iron would be an extreme hazard? i saw this happen personally. i had a charcoal starter chiminy set on my driveway. the explosive spall was quite dramatic, but the coal chiminy contained all of the flying debris. this was 100% radiative heating from hot charcoal btw. i didnt have the coals sitting on the ground or anything like that. obiviously a driveway is going to have a higher moisture content... but still is it not a hazard?
Excellent technical casting. Unfortunate that YT algorithm favours popular channels as opposed to good content. So much to learn from this video.

Wow, that was incredible! Your technique and patience are amazing. I really appreciate you sharing your work with us!
Now that is hardcore backyard casting :D ... another awesome video, thanks very much for the lesson.
It is amazing what one can do in their backyard.
Really impressed lucky. You deserve so many more views! Thanks for sharing, I always learn great stuff from your videos.

Really just fantastic,for back yard foundry! Hope you realize that you are the gold standard for home foundry followers!
Thank you for watching my videos.
I'd love to know more about the resin bonded sand you're using. "edit" and of course the answer I was looking for was in a text screen at the end.
Great video, may have solved a couple of tricky ones for me, was the resin Polyester or Epoxy? have you tried this with Aluminium?
The resin is epoxy and I have used it with aluminium.
Thank you for posting this. That seemed like a complex mold to form and cast; your videos are a wealth of information.
Thank you for all of your work !

Yeah I said a lot of naughty words but I had to make another to see if it would work!
Es resina?
you are a master of the craft, thank you so much for making these videos!
Really love this video. Your sand looks so nicely solid, do you use normal green sand or a special formula?
I use 1.5% fibre glass resin to bond the sand together.
@@luckygen1001 Hi, could you tell me how long it takes for the sand to go hard work time and strip time. by the way that's a great idea.Thanks Joel
@@TheSilversheeps There is plenty of strip time (many hours) It takes at least 24hrs to harden fully.
@@luckygen1001 for posting a great innovation. it sounds like it could handle some tough projects for cores thanks ...Joel
Really enjoying your videos here in Chicago. Thanks!
That was impressive indeed. I never thought about how they are made until I saw your video of making one. Bravo sir, Bravo.
Wow! The next level of casting!!!
Very impressive molding skills! It must have been frustrating to do all that work and then not get a complete fill.
great video, great job....beautiful,,,but i don't understand how the sand hard at 5:40.. Could you explain it to me?
Great Content, and I've also learned I now hear AvE's "Tappy, Tap, Tap" in my head..
You know AvE's quoting the movie, "Happy Gilmore", right?
I’m curious to know how much ferro silicon you add?
Excellent video. Not only 3 part mold, but also in iron.
Wishing you a Happy New Year filled with Peace, Success, Prosperity and Happiness in all that you do.

The impellor blades have very little draft and the sand has resin in it.
I felt for you when I saw the molten iron running on the floor. It looked such a good mould too.
Everyone on youtube saw it as well but I made another and it worked. The trouble is it is so time consuming to make the core and when it fails it has to be done again.
As long as you succeeded in the end. Keep at it. Regards, Ian.

Impressive...
What's your core sand recipe???
1.5% resin and hardener.
Turned out really nice👍🏻👍🏻👍🏻, much much better than the impeller I tried a few years ago. I have a suggestion of you plan on making another one, at 12:00, use a torch to heat the ring and it may release better.
I don't plan making another one soon but I will remember that tip.
stunning work here.

No extreme hazard here as the concrete did not spall.
fair enough. im guessing you have never seen or heard of it happening either?
If I spilled a large amount like a full crucible it will have time to spall.
What did you use to make the hard sand mold. It is much tougher than a typicale green sand mold
thanks
Fibre glassing resin.
What ratio sand to resin mix did you use if you don't mind me asking
At very end of the video it shows the ratio.
Thanks. just watch it right to the end :-)
he put the formula in at the end of the video.
Très belle vidéo pourtant un peut compliqué un peut je fait ça en aluminium de façon commercial facile bon courage adam Algérie
سلام وش من رمل قاعد يستعمل فيه..يعني كاين في دزاير...واش أسمو
I am impresst👍👍👍
Great stuff lucky
Don't you have a tea spoon to add sand? 🤔
How do you make this sand
Awesome, thanks for sharing!
not just gone to like ,bu telll u i love your videos iamsubscribd
thanks for the knowledge is very cool
Impressive
Holy sh t!
quite a bit of finicky you went thru
