Finding center... and hole layouts...

This is from a class lecture on hole layouts.

Thank you so much for explaining this. I’m needing to build some bed side rails for a headboard and footboard. The headboard and footboard already has pre-drilled holes, for a hidden threaded rod that fastens the entire bed together. Im wanting to follow the same pattern so that once the side rails are on, it doesn’t look like I rigged something up just to make it work. This was so helpful and very informative. 👍🏻👍🏻
