Almost everyone of my projects involve french curves. At times I spend more time designing certain parts of my projects using french curves than I spend making it. Just wondering, do you use french curves in your designs and if so, how do you align the two different perspectives? And one more question; where to get some mathematically accurate rulers?

I use french curves once in awhile, most recently on the plumb levels, but that was too match curves from a book and not freehand designing.

Is mathematically accurate different than just accurate? Incra makes some nice rulers, can’t vouch for their accuracy but I suspect it’s good enough for woodworking.

I cheat, I use my CAD program and print the result full size or any other size.

Using french curves to design this corbel for some shelves:

Thought it would be easy before trying layouts, but realized it wasn’t so easy because the corbels need to be much smaller than I originally thought, and the curve templates I have aren’t that small. Kind of a PITA but doable. Hardest part (for a dumb guy like me) is where those two curves meet in the middle and flare out a bit.

ColonelTravis, the curves sure can make some pretty designs. oldnovice, I downloaded the one you suggested but baffled by it. I have to spend some time reading the instruction or better yet find a youtube tutorial on it. Rick, french curves are based on mathematics and where the accuracy becomes important is in determining trends in the stock market. I use them both for woodworking and stocks.
