You’re making this for your aunt or uncle???

Dr bones is so cute

Super cool dude looking forward to the cannon breakdown

So oil keeps it from sticking? I been wanting to use molds that arent sand and dont know if the metals will stick

hey levi, you have instagram or any way i can get in contact with you? i would like to hire you for some work

If there is no bother, could you send me the designs of the 3d printing

Can this machine invest cobalt chromium?

Love seeing the process! May I know what the gear ratio is for the motors and how many rpm it has?

Hello, I have one question. When you bake the mold, you put it in the casting chamber in the vacuum system, I'm not entirely clear why? A negative pressure is created in the chamber around the mold, but the metal is poured into the cavity in the mold in which there is air.Somehow it doesn't make sense to me . Next question . The red seals look like silicone rubber, it has a typical temperature resistance of up to 300C (560F), but for example the material for making a mold for casting gold Prestige UNICAST has a firing temperature of 750C (1350F).

Be your own engineer just like grow your own food quality increases 100 fold ....

She was nice

This is terrifically dangerous 😢

This is terrifically dangerous 😢

great work! I'm looking to make a wheel similar to this - are you willing to share the cad files?

What are your resin settings? What program did you use to construct your tree?

Super cool! Do you do commissions for casted rings?

Hey Levi! Cool video! Can’t wait to see what you do next!

Do you find you get wobble with those flange coupler hub things? That has been my experience, I wonder if it’s just me!

Very creative solution to the ...compact windturbine problem ;)

You take a lot of effort to make this wheels, but i am afraid, that the motors you selected may not be powerfull enough, especially with very heavy wheel. Another fact is that you used 3D printed form. You should use machined one. All this air removal is partialy waisted by the roughnes of the form.

Hi. Can you please tell me what the maximum size flask this vacuum caster can accommodate? Thanks.

can this also be used for 14kt gold

After how many hours of the burnout process did you flip the flask button side up?

You could add a square base to the bottom of the crankcase. This would give you a mount for the engine to sit upright on, and something to hold onto when working on it. A couple of mounting holes in this base would help to mount it, say in a model boat or car. There were a lot of old spark ignition model engine with split crank cases back in the 1940's.

What program do you use for CAD when you create your part models?

You could definitely use a good little bench vise, maybe a 4 inch from Harbor Freight? Or pick one up at a flea market.

Those cylinders show, that you have done this before! A few times more...

This is an excellent design. I agree with you in that if it were made of metal - ideally stainless but also do a more expensive variant in Ti because people will pay premium prices for those - it would be perfect. Your problem now is finding a manufacturer as I am sure there is a market for these. I suppose you could sell a patent to Leatherman and they would promptly bury it because such a driver would reduce their sales of multitools, because many in the EDC community are now changing over to carrying Knipex Cobra pliers plus a knife. I've been looking into various alternatives for months now and trust me there isn't much out there. The Big Ideas Design Ti EDS is probably the best but it costs £130 which converts to $160, more than a quality multitool costs. At the moment I carry either a Wera 813 bit holder handle with the 2 inch Wera extender and bits of my choice, it's only about the size of a Bic lighter and is very capable. Other days I carry a Sabrecut mini ratchet with the same Wera extender and bits, it's about 84mm long so shorter than a regular Swiss Army knife and differs from any other mini ratchet (except for a couple for bikes but they are over 4 inches long) in that it has a bit holder in the end of the handle so it also can be used as an inline driver.

So what happened with this proyect bro?

Are you still casting?

Just check for used dental laboratory casting equipment. These are made for daily use for years.

NIce!!!. How about the traction?. I am thinking to fabricate my own silicon tyre for my sumo robot competition. But the silicon seems very thick, can i make i thinner?

nice!!!

Man, and I'm worried about putting a PSU on the rolling cart I have so I can occasionally move mine across the room!

Whats the flask outer dimension on the lip? Im asking because the rapid fire burn out kiln says only a 3 inch fask works and my vacuum machine came with 3.5" flask i think we have same model to

To calibrate a 0 to 1 micrometer all you need to do is bring the anvils together and turn the barrel with the spanner wrench you have and line it up with the dile. That's how to zero it out. No gage block is needed for a o to 1.

why didnt you buy the FG gas version of this engine. an 18x12 is insanely big for this engine. 17x6 tops. 12in pitch is very inefficient. FRsky gas suite sensor will give you flow rate. where is this project now? i really like your engine craddle, stand. what did you use?

Hello ..knife nut here wanting to learn this technique for actually creating a dimensional drawing to create a DXF file to help facilitate using a CNC program..any help or info would be greatly appreciated..

just know, the Kaya Cast machine is a fake one and not an original USA made one

It's cool to see your vacuum system still works thinking of buying that one

Any updates on the stl files?

Hi, do you believe this would work with castable resin instead of wax?

Did you make some money with it :) I am looking at this to case bullets

What's your 3d printer settings ?

That casting machine is a chinese one correct? How has it performed?

This is very impressive 👏, how does this not have more views. I'm happy to see you, trying, inventing, and putting your ideas down. I'm a chemist myself and really dig catalysis, metals, and organic chemistry. I don't have equipment to build things or as savvy as engineering students. I do think about it alot and have a note book with inventions. To see you working on your own, and putting your ideas 💡 to construction is very admirable and inspiring. Never give up good sir🙌

Hi, I would like you to cast bullets made of copper. There's a HUGE market for casting copper as currently lead is how people cast. Copper bullets are much better but the high melting point makes it difficult to cast. If you could solve a way to use the equipment you have to cast bullets it would be awesome. Even a video with a thumbnail of casting copper bullets would go vial. Even at a bargain a quality bullets is $0.40, idk how many you can make but if you could make 100 bullets in an hour casting. That's $40 , idk if that's worth it but seems like good money:)

Very cool 😎 Noticed that you didn't use the vacuum chamber you have at home for metal casting - do you still like that solution? I have been FDM and resin 3D printing, and now want to learn to cast, metals and silicone, soft plastics, rubber etc; haven't tiptoed into it yet.

Amazing video ! Excited to see the progression of the Sumo !
