I saw one of these at a show a little while back. The concept is solid but the jigs design is in dire need of work. Waaay to much room for error.

What kind of problems are you having?

Wouldn’t a convex curve cutter also be called a circle cutter?

That’s the sort of niche tool where I expect
you’d be able to write or call the inventor
and get some answers.

Yes, that device looks pretty much like a circle-cutting jig with some additional work-holding devices.

OP—I only know what I saw on the video that John linked to above, but the process looks pretty straight-forward. It seems to me that the off-fall from the convex cut, if thick enough, could be mitered and joined into a concave-sided box. What trouble are you having? (“No such luck” doesn’t tell us much)
