First thing we did as apprentices was make a stainless french curve to learn to use the bandsaw properlyNice kit Shox. I made a dress making version in stainless for the wife, I had totally forgotten about, I will see if I can find it, I love all the old stuff,
Wiki says the curves are sections of an Euler spiral, the curvature changes linearly along it's length. Whether they all follow that rule or not I can't say, I wouldn't be surprised if newer/cheap ones are secretly Bezier curves.Is there a science to french curves? Ie are they a standard curve or based on some maths somewhere? I have a set which I had since school but don’t use them much. I always wondered how they arrived at the designs of them.
Me too , I've also used a hose pipe with the water turned on full but the spray closed off to pressurize the pipe ... you can get some really nice large gentle curves not just on sheets of plywood etc also but out in the garden when planning a curved lawn/ garden bed area .I do, the compass etc, the curves , pus the old 1970's flexi curve.
