GH,
I agree. Definitely overkill for sport models. But like Bernard, if you have one, once you start using it, you don't build anything without it. It's not just that it's really accurate. It's that it's so easy.

With me it's actually, "hey, this thing is WAY better than me at putting on fins," LOL. I'm more than willing to admit my inadequacies.

Now if I can just find a similar tool for sanding.
