Thank you for the ideas. I don't have a band saw. I am cutting the pieces with a miter saw and a fine finish blade so I am getting smooth cuts/joints. I do plan on glue (Titebond) and screws and overlapping. The arch is based on modifications of one I saw in Popular Mechanics.

(this is just curiosity) Either way I would make a template and draw out the outer and inner circles, use a jig saw to cut close to the lines, within in a 1/16" then rout with your circle jig. Then with cedar or doug fir I would be comfortable with my depth of cut being 3/4". But shallower passes wouldn't be a bad thing either.
Thank you Bob, I am still undecided on the exact approach but was thinking Kreg pocket screws on the surface where the joints meet, and glue. The pocket holes would be on the inside of each 1.5" thickness side. I do have a good jigsaw and was planning on trimming close before routing. Hope my comments make sense.

Welcoms to the Forum and that's a really nice project. You have 8 segments for the full circle, four for an arch. Cut the angles first, lay out the half circle, and I'd use a pencil through a stick, with a sharp point on the other end to draw the arch. I'm with Stick on using oak splines to join them, otherwise you could use lap joints, but that will be trickier to measure and cut. Splines with weather resistant glue are very strong.

When cutting the splines on the ends, make sure you put the face toward the fence on every piece so your grooves are aligned. I'd cut fairly deep and use splines that were 3-4 inches long

Personally, I'd use 2x6 red cedar if I could find it so the arch would be a little wider. Where the ends joined the vertical sides of the opening, I'd go with a bit wider wood. But I live in the desert and the weather extremes will be hard on whatever I used, so I tend to overbuild a little.

I would make the curved cuts on a band saw, or a good jig saw. I'd roundover the edges of the curved pieces a little. Not sure this is much of a router project unless you used a pattern. But even then I'd make the curved cut with a band or jig saw, and use the router to clean it up. Cut just outside the line 1/16th with the band or jig saw and clean it up later.

One other option for setting up the curve would be to buy some half inch MDF. Cut it to the width of the arch, then using a trammel (stick with pencil on the end, a nail on the other. The inside and outside radius will be the nail insertion point. Draw the arc. You could do this on a small sheet of mdf, or even directly on your precut 2x. Place a same thickness piece for the nail to ride on.

Just thinking this out a little. The simpler the method, the more likely it is to turn out well.
Thank you for the input. My goal is to keep this as non-complex as possible! I appreciate the good ideas!

Welcome to the forum Robert!
Awesome that you are taking on such an ambitious project!
I wouldn't even know where to start besides to begin researching.

Be sure to show us a pic when it's finished.

With a 1/2" bit you should be able to make at least 1/2' passes. That bit has a 1 1/2" cutting length if I remember right so you'll either have to cut from both sides or use a pattern or flush trim bit to finish by running the bearing on them against the portion the up cut bit did.

One way to rout that is to attach the router to a long strip of thin ply. You can then pin that to the sheet you'll have the segments on at the 51" and 44" distances. Basically the router and ply strip become a long pendulum. I would still jig saw most of the waste off first. That's always easier on bits and the router. Leave a 1/16" outside the lines.

As for speed with a half inch bit you want to go full speed. Feed rate is governed by the sound your router is making. If it seems to be laboring then slow down. I would also slow down at the knots. WRC lumber has notoriously hard knots that can be very hard on carbide bits.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Welcome to RF, Robert...you will love it here...

Quite the ambitious project you have there and it sounds like you have an excellent handle on it.

With the advice you've been given you should have no problem executing.

Work slow and careful and the details will appear for you.

Ask away as you proceed...you sound like "think first, cut later" type...
