I have someone wanting me to build this pergala for them. I am wondering the best way to get this arc across the beam. I am thinking i can either use a router, with a jig/pattern, or if i should use a different route. I do see using 2 , 6’ length board to make it easier.

I think you have the right idea. Rough cut the curve with a band saw then true up to a pattern with a pattern bit in a router. You can cut the end profile at the same time

Your post made me think of a plan I saw in Wood Magazine last year. Here is a link to the plan. It may give you a couple ideas.

I would not recommend using two short beams to form each long beam. That will greatly weaken the structure.

Good Luck!

I’m with Herb here, although it looks like the original has some sort of connector at mid-span (maybe there’s a steel bracket covered by wood trim??). A full-length beam would be much stronger and long-lived, IMHO

You can use a jig saw for rough cut. Then use the router with the template on the curve beam

I think jig saw is great way to cut it.

That will depend on the dimensions of your pergola and how much arc you want. Got a design roughed out?

If you’re not a Sketchup user, you might consider checking it out (it’s a free download). I think it is a great design tool—-it will figure angles and arcs for you, and allow you to easily change and adjust at the design stage without wasting any wood!

Ok thanks. I tried that program once, and it seemed ok. Will probably take some time to learn, but would be ueefull
