Your videos are very enjoyable and informative! You can certainly tell you have 3 decades of experience because you point out the details that others gloss over or fail to mention to mention at all. You have the heart of a teacher and you’re good at your craft! From one foundry guy to another well done! 👍🏼 👊🏼

Yet another excellent video tutorial loaded with rare-to-come-across hints, presented in a concised manner. Looking forward to seeing the next videos. Liked, subscribed, commented and shared. ⚒️📝🔥

Thank you for these videos. I have learned quite a few things that I didn't find reading or anywhere else

[felixseib]

Again, very nice explained. This is a step, that is nearly never discussed in detail in youtube videos. Thx. There is one open question for me: What material are you using in your sand blaster? I also work with sand blasters in my job, and I know, that this can make a big differnce. I am excited to see the finishing of the skull. 😊

[DragonAtelier]

I always wait and I am curious for your new videos 👌 this one will definately help me with my shell removal process 👌 hopefully in my next video I will use tour advices ☺️

[swilson]

Eric, thank you for being so gracious in sharing the information you have here. Will you be posting the final video on chasing. I have learned so much from your in-depth videos.

[Yasmana]

Hi. Would you mind making a video on Patination? will appreciate it.

[corrybrown]

I’m curious would a repeated process of heating and freezing work to possibly help loosen it up?

[anitalim]

Do you have to be more careful when chiseling off of certain metals than others because they could have softer properties? Can you reuse the metal of the sprus that were cut off by just melting them again?

[mikep.coplin]

You should buy a five dollar, four inch dia. magnefine glass. It will work great with your cameras, in showing the casting detail works. Just some thoughts !

[Pakhomeguns]

Do you know any formula with more easily available materials to make the ceramic grout?

[TheOnlyWes]

Sir, as I watch I'm wondering... is there an ultrasonic scaler – just like the ones used by dentists remove calculus/tartar – made for casting/metal work? That would be cool to see the shell being smashed like tartar lol. Also could be easier to remove the insides of that skull. Amazing channel! Wes from Brazil here.

Hi Eric, Thanks for your videos. It is so nice you share your experience.
May I ask a question please. I have a problem I can't figure out.
I tried to cast parts similar to yours in size and complexity.
The ceramic shell inside the part is uncompressible and very stable due to it's dome shape. It is not so easy to crush it by squeezing.
When molten bronze cools and contracts it cannot crush the shell and cracks itself. I tried many times and always get this result.
Thanks!

[munchegod]

Thanks for the video very helpful, off topic question, got any tips for dealing with contraction cracks when casting spindly aluminium parts?

I've been increasing the number and size of feeds as well as a face coating of crystalcast but due to the nature of the wax there's only so much I can feed in before the fettling work gets out of control.

[Metalfusioncowboy]

Hey, what Media are you using for the sand blaster? Thanks

[danielross]

I wonder if using investment plaster for the first "dip" and then ceramic for subsequent dips would make it easier to clean up...

[PhaseFabrication]

have you ever tried to 'glue' multiple 3d printed sections together to cast bigger parts? I assume using that sprue wax should work..
Also is there some weight/size limit of the pour due to weight putting stress on the shell?
& have you ever tried using watered down drywall joint compound/mud instead of this expensive remet stuff?
