you may have many answers to this already, but as shown by many, one template then can easily duplicate all the rest.
something to think about, with ones "determination" of the nose rib drawings, and converted file for the laser does not mean that it would match your spar height, unless of course you waiting for these (nose ribs) to then determine the exact spar height. (recommended)
best of success.
ps..using the router method, once the template is made and parts drawn on sheet, you can get rough size done quickly and we always made 4 at a time after that. Goes fast.
