Seriously dude, how many people will light up a torch after accidentally left a propane tank leaking gas. Do you realize how stupidly improbable is that?Have you heard of propane ranges? Carbon monoxide, seriously dude? Propane burns pretty clean, you know how many running stoves you'll need to exhaust breathable air?

What type of rubber is that in the vacuum system? Thanks

Good work

Is there a specific type/brand of vulcanized rubber I would need to use in the toaster oven? And what heat setting (degrees) should be used? Thank you very much.

Great video ! Thank you

Hey Craig What’s the size of the actual letter on the ring ? 2 or 3 mm? Thanks

where did you get that ring frame? I'm having a hard time finding those with built in ventilation

As you can see there is a variety of ways to use the clay and the small rings positioning of air breather holes this is a perfect video for folks that are new to this Delft casting process I like it much better than investment casting it’s so much cleaner no water no bubbles Very good video and technique thank you

Great video!! I've been casting bronze mounts for miniature furniture for years but have never had a debubbling machine. I usually put my investment flasks on my fretsaw which vibrates and tap out the bubbles with a stick. I can be hit and miss depending on the thickness of my investment (I don't measure it, I do it by eye). After watching you vodeo I just bought your debubbling machine, can't wait for it to arrive. I'm going to use my compressor in reverse with the machine but am concerned how much pressure I should look to get when I run my compressor. When I use my wax injector I have a precise setting I use and wondered if degassing will be similar...

Which power is that??

Cool thank you. Subscribed. Would’ve been even awesomer if we would have been able to see the results up close.

Do you think I could season a crucible with that torch? Thanks

I'm new to pouring. Every time I "pound" the clay into the mold, the clay "cracks" in certain places. It usually doesn't crack or split, where I was using the hammer. When I add more clay, it still happens. Is it possible I'm pounding too hard on the hammer? Thank you in advance.

Hi, just wondering what kind of torche that is, and also the name of that white material inside the steel?

Will you be restocking the mini core flask kit soon?!

I was wondering should you wear a mask so you don't breathe Borax

Amazing work 😍

If you got a great result with just hand-tight wing nuts, why are there videos out there saying it has to be 3,000psi?

Why an oxygenating flame?

Have you ever tried using the sandcast method. To make wax ring paterns for lost wax casting?

what type of gas are you using?

thank you for the video, it was very interesting to watch your techniques

What kind of stones can be used with this method?

Remelt it and pour it.

Learning to Solder Gold..........

doesn't this soften and distort the cavity?

It will pull apart if you paint the surfaces with the talc using a small painters brush. You don't put enough talc on. You can also use corn powder.

I use arc plasma for pgm it is faster and safer

Halli i have a question. I am sand casting a thin ring i made 2sprouts bud the silver don’t want complete the ring it stop half way and everything is neet and clean

Thank U very much for vedio. Plz Can I use the same procece with wax pronge ring? And if I lay the ring in molde it give the same result or only this is the way?

Thank you 🙏

Where can that circular mold w vents and top pour be found?

Do you have a link?

it is easier if you put a lot of separating powder on the edges. very easy to split.

Hello Craig thanks for the video, one question, is possible to do a name with this technique? thanks!

Once the ring is fully heated it leaves purple firestain all over the ring...what's the best way to get rid of the firestain?

This video just helped me tremendously thank you craig

Once the mixture boils and explodes, is there enough vacuum in the bowl? Do you have any empirical rule to know when is enough time to know until it is enough to degas the flasks? Thanks for your videos!!!!!

what type of burner do you use?

I use oxy propane little torch ! Have no probs !

Hello Craig, Does a vacuum table make a big difference to the quality of a sand casting? Thanks

What kind of investment are you using?

When you say you put it in the oven afterwards, fo you mean kiln or standard oven to dry it out?

Best I've seen, the really important attention to detail makes me think I could have a go at this !!

very nicely thought device. How to order online ?

Hello Craig, What are the benefits from vacuum assisting sand casting?

Silica is the worry your talking about bud. Great video. ❤

How it is possible that stone doesn’t break when you put them on the water

Thank you for making this video, you truly remind me of Ranchodas Charchard.
