Elliptical

mikec

Hi,
I'm putting vinyl on a house that we built an addition on. It has an andersen french door with an elliptical transom over it. We're using 2.5" J around all the windows so I need to duplicate this look over the transom.
My plan is to cut a trim piece out of a sheet of azek. Today I made a template out of cardboard, copied it to plywood in hopes of using it as a router jig for the azek.
I made the plywood template about 5 inches wide so I could take it up there scribe it and fine tune it. Problem is the more I mess with it the worse it fits.
This transom has more than one radius, but does anyone know of a method for laying it out, without trying to scribe it? I know how to draw a radius with a framing square, but like I said it has more than one radius, and is six feet wide. I can't do that with the framing square.

Azek is bendable w/ heat. The supply house you purchased from may be able to hook you up w/ the Azek rep who should hopefully get you hooked up. Are you using all smooth surface and not grained surfaces? Let us know how it turns out

I'm not sure if this is what you're asking for, but here it is anyway. Joe's site has a lot of great information buried in it.
