I cast a 6 spoked spider curved wheel for a chapel bell. I did not use a 2 part mold. Aluminum sometimes leaves a beveled edge , so I top poured the wheel and it matched the beveled other side very good. It was fun to watch the aluminum run into the mold and fill in all the curves ..I plan to make another one soon.
I just found a flywheel to use on my gas conversion compressor. I have seen the prices of these things in the wild and it is insane. Great video my friend.
Thanks so much for your videos. I just did a 3D printed water hopper for my Upshur engine. 2 first 1 was the 3D printed master and the 2nd was the use of a core. It turned out great.
That was a beautiful casting, it looks like it took a lot of filament to make the mold. I'm waiting for my 3D printer to arrive and getting it put together and learning how to use it.
Beautiful job start to finish! I was surprised how well it turned out considering how cool the Petrobond was. I have had voids from the aluminum cooling too quickly when casting in really cold weather.
Well Myfordboy if you lived next door to me when I was a kid I would have adopted you as my grandfather! My grandfather was gone before I was born when he was only 56 and he was quite talented as well. Would you mind showing us a vid of you cleaning that wheel up. It's the biggest one I have seen you make so far. Thanks
Great video! May I ask what type of printing filament you used for this cast, and would you consider making a short video explaining which type of molding sand suits what aplications the best. I would like to learn more about metal casting, but there's still a lot of things I find very confusing. I hope you keep making these type of video's they are very helpfull!
I use the Bromsgrove greensand from here www.artisanfoundry.co.uk/product_info.php?products_id=38 for everything. There are some videos on how it's used like this one ruclips.net/video/CxUc92N0E6Y/видео.html
Nicely done as always. Could you tell me why you stopped using scrap alloy wheels and switched to ZL-12? I'm considering having a go at casting, but on a budget, and ZL-12 ingots seem pricey compared to scrap wheels.
You know your detractors say your degassing method doesn't work. My question, where are all the bubbles coming from. LOL - You consistently have great castings, or don't show us your failures. You have taught us a lot about how to get good castings. Another great video.
His methods are flawed. He lets the metal cool while degassing and fluxing, and you can tell by the way it pours. He is trying to build himself up, by tearing you down. Keep making your great castings, we enjoy watching.
Hello my ford boy I've just started in foundry work and have been looking to find info on degassing and how much borax to use as a flux plse help .....very impressive fly wheel by the was and as ole mate said you make it look easy lol
Borax is a flux for brass. For aluminium I use this www.artisanfoundry.co.uk/product_info.php?cPath=29&products_id=34&osCsid=8vj5ikn2mc17t1ng7mnh7m8503 Previously I used table salt or even better LoSalt. Half a teaspoon is enough.
you always get a very good finish in your parts and no porosity I wonder if using baking soda would be ok for degasing the hydrogen I have seen guys with aluminum looking like Swiss chezs
What dia. Is this wheel? And what size crucible were you using? I have an A25 crucible with an 4.8 liter brim full capacity. The largest part which I’m trying to build my foundry around is a 19” pulley sheave. And how would you sudgest I machine it with a lathe tha has a 12” swing and 24” bed? I’m thinking I may need to make a machine just for this. Seeing as how I simply won’t spend thousands on a machine that will only serve one small purpose. But I was wondering if maybe you had made some sort of attachment for turning one.
Very good all your work! One question: how do you prepare the land, do you put something special in it? I saw in some videos that the earth is black and in others it is red. I send you a big hug from Argentina. Thank you very much.
Thank you very much. I tell you that in Argentina, in the province of Misiones, the earth is red, clayey and very thin, and I think it would be ideal to make molds. I send you a big hug. Thank you very much.
Good morning, Greetings, friend I am from Venezuela and I have a small foundry, I am a lover of this work and I live it, could you explain what you do in the 12:02 minutes? after wear! I hope your quickest answers, thank you!
First sodium carbonate(washing soda) wrapped in foil is plunged to the bottom. This creates bubbles to drive off hydrogen absorbed during melting and prevents a porous casting. The an aluminium drossing flux is added which makes the metal more fluid and brigs up dross that can be removed.
@@myfordboy mmmm is fine, here in Venezuela we discover a slightly more archaic way of degassing, once the liquid aluminum is intruded to the bottom a small piece of pine wood, and the porocity is minimal. If possible I would like to continue exchanging knowledge with you!
You need bentonite clay. I tried it to see but it was not as good as the proper stuff, the sand is too coarse for one thing but it does work. ruclips.net/video/l638qR0Y6YE/видео.html
Thanks for the reply. That is exactly the sand I had in mind in your link above. I bought some at Home Depot for use in my sand blaster. Now all I need is the bentonite clay, which I am sure I also saw at Home Depot. 1Kg sand to 120g of clay. Thanks for the recipe.
Hot diggity, that is one fine casting... Also, what the hell did you melt down for it to produce such a ``hard`` structure... That sawing action seemed like much more hassle than i usually find with aluminium... Just after the deslagging the metal seemed quite nice, pure or at least a well combined alloy if alloy it is... After giving it a fluxed hot bath, that surface seemed even nicer... And the casting itself mirrors and tells the same tale of a very good metal purity(not as in elementally pure, but as with no unwanted ``alloying`` elements)...
@@myfordboy Aaah, my favorite for melting... Scrap wheels... Good choice, and a mighty fine repurpose for good old quality metal... Once more, your results are lovely!
If you printed in ABS and then used acetone vapour smoothing you might find it would come out of the sand a lot easier. Something to research and try if you are interested.
I always have to laugh seeing you using one of the latest pieces of technology to make patterns for an ancient technology like sand casting. You do some really impressive work. I built a similar casting setup a number of years ago and used it to cast the parts for a Gingery lathe. I'm curious about a couple of things. Are the blocked-off corners on the cope and drag just so you have a way to hold onto them after they're filled with sand? And what was it that you put on the hub of the pattern just before you added the riser, and what was it for? Thanks for sharing the videos. Very relaxing to watch. :)
The corners in the flask were added when I only had a small supply of sand. The brass disc locates in a hole in the pattern and the riser fits over it to keep it in place when ramming the cope.
That's big - looks like about the biggest you can do? Only just enough aluminium anyway. It's a bit hard to tell from the video, but it looks like there is no draft on the outer face of the flywheel, but it came out of the sand pretty well. Don't you need draft on something like this?
That's the biggest I can do with the A10 crucible which the furnace was designed for. I can go a to little bigger crucible by removing the plinth. I can also go bigger by using a stainless steel cooking container as a crucible.
You can measure the volume in the Cad program, displace it in water or use your experience. I melt a full crucible each time anyway and have other moulds ready if there is any over.
Metal always shrinks as it cools so the pattern has to be made larger than you want the finished casting to be. For aluminium I make the pattern 2% larger.
Thank you. That's really good to know. I guess you also want to add another percent or two to give yourself enough material to clean up the irregularities on any surface you intend to machine?
This is the flux www.artisanfoundry.co.uk/product_info.php?cPath=21&products_id=34&osCsid=d6fi9dgk1q03n76ke64i3k0bq0 To degas i use washing soda crystals ( sodium carbonate.) from the supermarket.
very nice. you make it all look too easy though! how do you get your patterns flat on the bottom so they part nicely? complicated question sorry, but i have trouble with printing like that
Hi Emma. Not really had this issue. I used tape and gluestick. The centre of the pattern raised a little, you can see it in the video but I have had this with wooden patterns after time. It's not a problem though as it gets pushed flat when rammed up.
The finish of your casting looks very good, I wish my attempts would turn out as nice, for degassing you use sodium carbonate? can you tell me what do you use as a flux please. Regards Paul
This is the flux www.artisanfoundry.co.uk/product_info.php?cPath=21&products_id=34&osCsid=d6fi9dgk1q03n76ke64i3k0bq0 I have used table salt and Losalt which works too if you want to use household materials but this flux is better.
If the riser were part of the pattern you would not be able to remove it from the sand. If I have a lot of one part to make I will include the gates in the pattern.

never seen such a precise pour before in my life, well done
That’s the largest flywheel I’ve seen you cast so far. Can’t wait to see what’s it for.
I am amazed every day. The affordable technology that is avaible to the hobbyist today. I enjoy your videos, thank you very much.
The author of the homemade product is just special in his business. I've never seen such a large casting (pulley) with my own hands. Good job.

Ahh I see. So large diameter stuff is not an issue for you. Interesting the way you set that up.
Will you be showing the machining,I'd be interested because of the size, 11.5" is a big swing for a home shop. Cheers Peter
He gots a specify device for his lathe to clamp large diameters. I don't remember Which is, but you can see in a old video
I am not machining this it was made for a friend. I could do it though like this ruclips.net/video/2ivuCRavE8I/видео.html
Did you print the holes in the pattern for the locating pins?
How long did it take to print both halves of the pattern?
Holes were printed in the pattern. Something like 10 hours each half to print.
