Excellent explanation....... clear, concise, and easy to understand. Thank you.

Thank you for a very informative video, just getting into lost wax after sand/delft clay and cuttlefish casting with aluminium, brass and silver. It is very helpful to see the process done by professionals!

That was the best thing I’ve learnt in many days.

This was a fantastic video, It was really helpful for me to learn about this process. I thinking im going to have a go at this to cast come hydroelectric turgo spoons soon.

Should make you some custom silicon sleeves for your flask

Excellent video and very informative. A Big Like👍 to your video from India

And here I am working on a MUCH Smaller scale with Silver and Gold.. But WOW lovely.

Great video, where do you source the large perforated flasks? Can't locate anywhere with flasks bigger than 150mm diameter.

Good work and Very good attitude

Very nice explanation of all process Congratulations

Hi Mark, thanks for the great video. Impressive set-up. Clean and well organized. You have the process down to a science and it shows in your cast bronze pieces. Just wondering why you chose classic plaster investment rather than ceramic shell? Is this for an architectural company? Thanks.

Hi Rob i love your videos, i was wondering whats the type or name of the vacuum you are using? is it custom vacuum or? i cant find any information online, would be very helpful if you can give me some tips thank you

What kind of metal alloys do you melt for your castings? Do you take jobs?

Hi Bob, please show more videos of bronze casting

Excellent. Thanks.

That really old episode of Mythbusters. I'm sure it was first season. Adam got his eyebrow burned off. I think it was the cellphone caused the gas station explosion story

I just started doing this at home in Sydney during the lockdown - Im only using Bismuth and Tin so can get away with using a stove top cause they're low melting - this was a mad video. Can you point me in the direction of a brand of ovens good for wax expulsion? Thanks again for sharing.

Excellent casting result. What type of plaster do you use? Thanks

Great video. Definitely better than 8 out of 10 ;-)

What type of plaster do you use? The one I used always cracked

Great video, one question, vacuum pulls air from plaster and that's how you get that sharp cast? But if you pull air in proces when you put plaster over wax how vacum is made after this ? And can you let us know where to get wax in granules? Thanks.

I couldn’t work it this work shop with all the wax all over the place. I worked at a factory that did this work years ago when I first left school and everything was kept very clean.

Great video bro. Subbed. I am just about to the point of casting stuff myself.

I work in a aluminum foundry been there for 20 years when we poor we wear spats on our shoes and we have aprons our ladle holds 25 pounds of metal and the tongs are separate from the ladle I didn't see an autoclave because your burn out has a wax catch pan we autoclave our casting to melt the wax out and we burn them out at 1700 degrees for 4 hours than we clean the shells and load them into a holding oven between 900 and 1300 degrees before we can poor them we also degas the mental and take a test slug before we poor any thing we check for gas holes in the slug if it has gas we don't poor till we get a slug with no gas holes

its so nice a video, so informative.what kind of investment did you use in your lost wax casting? how what proportion or just according to label instructions? can i do lost wax with your investment on 48 inch - 4 blade boat propeller? thanks sir.

Hi Bob, please show me more videos of the casting method

You have an amazing set up there. Very nice work too. I envy that.

Hey it's an excellent learning.. What is the flask size you use and what's the burnout temperature required to be achieved for a flawless casting.

What is the duration of gypsum curing and the process of increasing and decreasing the temperature. At what temperature do you melt? What is the temperature of the plaster when it is melted?

Hello Rob!

Can you do a video on making the moulds??

Bagaimana agar gypsum nya tidak retak ketika di panas kan mister?

Can you tell me vaccum pump CFM?

Instead of taping up the holes on the flasks, why don´t you cast a silicone rubber sleeve type of thing. You could then simply put that sleeve over the flask in one go and save time for all the flasks this would add up.

Osem bro I am fen you work and your telent I have a start iron teeth molding exveter can you share your all materials list to this castings prossecs

How do you make the master pattern is what I wanted to know

3:45 I think that is called a weld.

How much would you charge me to do a lost wax cast of a small trinket if i was to send it to you made out of the wax product of your choice? It would not need to be perfect. In fact some air bubles and imperfections would be what I would prefer.

hey! is the slurry you made to coat the wax a ceramic slurry? also another qn: How do you make sure there are no air bubbles when the liquid metal is cooling? also This is such a great video to learn about lost wax casting! I am using it for a manufacturing part in my eng course

👍

What is the temperature at which the metal melts?

My neck is starting to hurt

❤❤❤❤😍😍wow

good lad

The tape to seal the holes in the flasks seems quite a waste of plastic. Why wouldn’t they make a removable cover that can be reused?

What kind of metal alloy do you melt? Do you take jobs?

How much door bronze handle?

Do you melt metal with gas?And which gas?

Hello Bob

Hello Rob, do you take on private work of this nature please?

Please share the vacuum pump detials... from india

Hi Rob, we would be very interested in sending you some lost wax casting work. If you are interested please drop me a line. Dave from Owl Castings Ltd.

Anyone wanna link up and just make it happen 💯

Don’t kid yourself… you’re a 10, not an 8.

8 out of 10 huh?

Who even biys those products ? I always thought some nameless faceless chinese fella in some huge machine does this kind of work, and once he falls dead to the ground due to lack of protective gear he will be replaced by some other dude named "ling". Who are your customers ?

8 out of 10 pushing a 6.5 to 7 until you start talking and mention ingrots. Look at what it says on the invoice, it’s bronze ingots.😂

Great video. I had a question about this vacuum chamber/table on wheels, was it scratchbuild or is there a manufacturer ? (and which one?)

Hello Rob, very impressed by your work, My name is Abdel and I own a factory in Egypt i would like to talk to you if you have the time, I think we can do some business together. Let me know how i can contact you, thank you very much!
