Very cool! Keep it coming. 2:21 Cavities in the cope have vents to let the air out, but how come the riser doesn't? Wouldn't air get trapped in the riser cavity?
Great observation, and thanks for the kind words! 🙌 The riser doesn't typically require vents because it is designed to act as a reservoir for molten metal, staying open at the top. Any air trapped in the riser can escape through the open end as the mold is filled. Moreover, the riser is not a part of the cast and it will be cut away and re-melted. In contrast, cope cavities need vents because they're enclosed and could trap air pockets, which would affect the casting quality. Hope this helps!

Ai scrfipt reading, boring script.
Probably ripped from another creator.
I lasted less than a minute. 3 dots ... dont recommend channel.
Less than a minute? That’s a new record for a fast-forward! I promise to work on the pacing for the next video.
