This is the pergola gate I’m thinking about trying to reproduce (It’s not going to be an exact copy). I’m mostly interested in understanding how they achieved the 4 arches that create the ring. I zoomed in on one of them and superimposed a board onto an arch to get an idea of how big the lumber would need to be if it was cut from a single board. I’m not sure if that’s how it was done.

I found this article on how to build an arched arbor but their approach results in a lot of screws in the face of the boards (which works in their example because they paint it—I’m planning on keeping the wood natural with just a water sealant.

Also, once they have the two top arches, how do you think they secure them to the rest of the structure at the top without exposing any hardware?

Thanks in advance for any help you can provide!
