Cutting curved wood for Rosette

[Bob Moore]

I see a lot of luthiers creating wooden rosettes by piecing the wood together in a circle, then cutting them out.
How do you secure the wood in order to make the cuts?
I have a 2 foot X 2 foot plywood block with 4 pieces of 3/4" plywood. I use this for a number of jobs, including routing the rosette and the sound hole. I have the StewMac circle cutting jig and stick the pin into the plywood. Could I put the pieces out at the radius I want and use double sided tape?
My rosette will be b/w/bloodwood/w/b. Then I intend to cut in 3 pieces of wood. One each inlayed at 3, 6, and 9 o'clock. Those pieces will lay with their centerline over the centerline of the bloodwood purfling.
Bonus Question: Any reason not to go with LMI White Glue? Does the top need to have a wash coat of lacquer or anything when using white glue? - It's 2 questions, I know. :) I cheated.
Thanks,
Bob

I use double sided tape. And Titebond Original.

Bob,
What I have done is take a back board, like your 3/4" ply, and glue a piece of note book paper to it with a Titebond or Elmers even,
then glue your wood to the paper. Do your routing, and when you want to separate it, just slide a putty knife under the paper and you have your rosette in one piece backed with the paper that you can easily remove. Works great.

Thanks, Guys.
Do you see any need to protect the top from the wood glue?

[Kevin in California]

Do you mean if any of the glue gets on your top when installing the rosette? No problem, just us a damp paper towel and wipe away any squeeze out off the top, anything left after that will sand away easily.

I think you have your answer, but I like Kevin's method with the paper. I also use double stick tape and it holds just fine and releases easy enough. I have not lost a rosette yet to tape!

Excellent! I have the wood coming that I want to use on my current project. Even now, I'm not sure what it will look like. It should be at the house when I get home.
I was pretty sure that wood glue wouldn't require any special care, but I've slept since I learned that and wasn't sure. Boy, you sure have to be strong to get older, huh? :)
