I saw something like this in a book but it didn't really tell how to make it.

Wondering how I would attach it and what would I make the pole out of?

You could buy a stakeout pole (see the link).

Or I've seen guys just cut off a broom handle and stick it through a scupper hole (if you're using a SOT), or attach to an anchor trolly. That would be a much cheaper option. I've have been thinking about getting something like this myself, to quickly be able to "drop anchor". Hope this is what you are looking for.

Ya, I think I will be making one lol. I got some wood in my shed I think would work.
