Here's a little jig to help mark arc layouts for making routing templates. Friction is an issue with keeping the bow equal on both sides, but it's easy enough to correct. This is like others we've all seen, but this one has a registration fence to help keep things square and hopefully easier to operate.

I very much like both of the other examples that were posted. Thank you. So many ways to skin a cat.
