I made this video & these cores before I cast the shaper hand wheel. I originally planned on using a core to form the hub hole in the casting. Instead, I drilled the hole, but decided to release this video anyway.
This is video is really 2 in one.

Second half. What Is a Core Drill?
A core such as this will produce a hole in a casting & minimize shrinkage in a thick portion of the wheel.
