AZFiddle replied to Julian Cossmann Cooke's topic in The PegboxMy first post - I'm excited to be able to add a small drop of suggestion to the ocean of wisdom I find here. A camera lucida is a good direction. My wife, a painter, sometimes uses an App on her iPad called Camera Lucida to duplicate portions of photographs. I tried it once on a non-violin project and was able to "project" a 2D image onto a contoured surface. It was a bit fiddly, but worked OK. If you can position the standoff distance to get the dimensions and alignment on the plate correct, it might work for an ff hole. Not sure it's better than a trusty template cutout. But might be worth a try. I included a link to a YouTube demo. If someone tries it, let us know how it works.
