Thanks BobBob N said:This sounds like a job for Template Tom. He is a member of this forum and a great teacher. When it comes to templates, he is the man.
Look him up in the members list and give him an email, he will be glad to help.
Just logged in Yes making the slats are quite easy I will need some information re the length and the amount of curve you require.
You will require template guides and a straight cutter. Constructing a simple Jig holder to hold the matereial and a template to guide the cutter with the aid of the template guide. I will make up a detailed drawing and post it then others can see the results. Not all will agree with the method but it will be different to what most router users use
