Logoing With Grain Filler

[Mitzlflik]

Happy Holidays,

I am about to start my firsts project which will be a soloist style guitar done in swamp ash with a voodoo type finish (white on black). I thought I might dremel a logo into the maple headstock-paint it black and user filler for the logo instead of a traditional inlay. My question is twofold: First, is a 1/16" rout deep enough to have a clean looking/filled script? Secondly I am looking for some names of suppliers providing lettering templates or raw material to make such a template?

Thanks
