I need to cut a 2 3/8" thick cedar panel into a shape that has an arched top. I've done several of these using my handhend jigsaw and a good blade, but I still end up doing a lot of belt sanding. Its 24"x80", too big for the bandsaw. I might try making a 1/4" thick template and get a 2 1/2" long bit and cut it with my handheld router. Is this practical? It sure would save a lot of sanding if it works. I think this has been covered here before.

It's very doable if you don't try and cut it full depth in one pass. Assuming you will be using a bit with a 1/4" shank, set your depth for about 1/4" to 1/2" per pass and you should be ok.
Cedar is one of, if not THE most irritating wood dusts to get in your lungs. Many people have bad allergic reactions to it if they don't wear a mask while producing lots of dust, like a router does. The dust from the router will be a lot finer than from your jigsaw, so keep that in mind.

Hi Chuck,
I think the template and router sounds like a good idea. In addition to EmpY's suggestions, I would recommend using a spiral end mill as opposed to a typical 2-flute router bit. I like the ¼” down cut two flute solid carbide bits made by Whiteside or Freud.

the router would work well... I use mine allot. to make the work go abit faster, make your pattern and lay it on your panel and draw the pattern onto the panel, remove the panel and using the jigsaw cut about 1/8" to 1/4" proud of the finish cut line. attach your pattern and finish up with the router.

Chuck insted of a bit that long why not make two templates and flip the piece over.May be safer-just my thought.

Empy has it right.
A pattern for the router to follow in shallow passes is the way we did it before we got our Gerber table router. At the cutting length your considering I'd go for the 1/2" shank though, and cut no more than 1/2" per pass.
