Works well for me. Doesn’t seem to effect the sand, its only a very thin coating.

Ah, so talc works well as a dusting powder? Correct me if I’m wrong, but doesn’t talc absorb moisture out of the sand?

There are 3 …
There are 3 location points added to the pattern known as core prints. These leave a void in the sand to support the core in the correct location. You can see this at 4:40.

How do you get the sand cores centered? It seems like they would sit on the bottom of the mold, leading to one side being very thin and the other side thick.

If you compare the pattern with the finished casting you will see the two parts of the pattern when fitted together have 3 extra round sections on the ends. These are the CORE PRINTS and form impresions in the sand to locate the core in the correct place.

Yes, some insight to your post-casting work would be interesting as well. This is an excellent companion to the Lindsay books I have purchased in the past.
A picture may be worth a thousand words, but a video like this is priceless!

Great work. just …
Great work. just wondering what material do you use to form the core? is it the same sand mixture or do you use a core binder?

Good point.
To do …
Good point.
To do it that way would be more difficult.. The pattern would need core prints added to the sides to make the cavity for the core and the extra part of the core would need to be perfectly aligned to get the apature in the right place. Only took a few minites to drill it out.

Beautiful work once …
Beautiful work once again. 5 stars!!!
I was wondering… Instead of cutting out the panel on each side to remove the core, why didn’t you just make it part of the core?
