Thank you for the demonstration of the product I just purchased. I am looking forward to practicing. I am thrilled to have a way to pour but address the reality if shaking hands.
Hi Craig, like your vids very helpful! Thanks for posting! I am going to try my first investment casting, can you reccomend how thick should the investment should be between the flask and part?
If too thin you may have a blowout where either the metal slams into the end of the mold breaking through or the vacuum actually sucks the investment and or metal into the casting unit. To prevent this it depends on the thickness of the item being cast so if tiny and thin it could be a minimum of 3/8 inch and heavier items 1/2 inch or more. Follow the manufacturers recommendations of the investment for water to investment ratio so it isn't mixed too thin.

Craig, thanks for your reply, do you think your mini oven concept would be successful using a 2.5 x 2.5" flask?
@@blairg420 no, too big. It all comes down to volume and this would be too much to heat.
Ok, what size of flask do you demo in your mini oven video?
@@blairg420 2.5 inch tall x 1.75 inch diameter.
I just bought his sand casting stand and flask very Cool 😎
