Just how good a compass do you want? The best ones are bowspring so they don't open up as you're drawing a circle. Much better than the normal ones.
I've got an ordinary one of a reasonable standard here that I'll pop in the post if you bung something into a charity.
I'm keeping my decent bow spring ones though, even though they've not been used in twenty years.
ETA, now I've seen your 14" requirement, I think you're going to struggle.

What did you have in mind? Will it manage a 14" diameter?I've got an ordinary one of a reasonable standard here that I'll pop in the post if you bung something into a charity.

k, I've now seen that you want 14" diameter not radius.
A decent bowspring with an extension bar will be the best way to do this.
