Yes, great method. …
Definely worth watching, thanks!
Yes, great method. That came to my eyes too, since the degasser tends to float on top of the oxide layer and I’ve had problems with that..

You are very honest …
You are very honest as well as skillful,
Not many would admit to failure.

I think your both …
I think your both sugestions are correct. I dont normaly add a vent for small castings, but will in the future ( and add the bicks).
Thanks for your ideas rocco.

As I watch that …
As I watch that video, I think one of two things, maybe both, are happening, I don’t see a vent in that mold, maybe hydraulic pressure opened the mold. Either that or the sand is floating. We don’t normally think of sand as being able to float but it is less dense than molten aluminium so if there’s enough volume of aluminium and surface area at the parting line, it can happen.

It was interesting watching the video after the casting was done. I thought I hadn’t closed the flasks properly but you can see on the video how they were forced apart when the metal was poured.

The few times that …
The few times that I’ve done larger castings, I used weights but, for small stuff, I haven’t bothered, I think I’m going to change that.

I usualy put a couple of bricks on the top of the flasks to hold them together but as these were only small castings I didn’t bother. Mistake!

Once again, great stuff!
It’s always better to learn from the mistakes of others than one’s own mistakes. There’s one mistake I won’t be making now, thanks for sharing!

One of the things …
One of the things about your efforts is how you discover new tricks. Putting the degasser into an aluminum foil packet so it can be pushed to the bottom of the melt is clever.

Been there !!! When I had my first wooden flasks I had a similar hydraulic blowout which quickly set the flasks on fire so I added some clasps to keep it from happening again. I always enjoy watching your projects, keep up the great work ! -Hank

A painted pattern will come out of the sand easier.
Sand will not stick to it. Sand needs to correct consistancy, not too wet but holds together.

Love the vids, you have a great setup. What are these parts? Are they for the stickeny?

whenever I pull out my wooden model of the mold, just dropping a piece of sand the border, such as the thinner parts …
the sand falls out, leaving a strain on the number …
will be little moisture in the sand or because I do not paint the molds?
