How to radius *NON*-square stock?

[fritter63]

I've been working on some projects that use wine barrel staves (post and pictures coming soon!) and would really like to have a nice consistent round over radius on the edges. The trouble is, there's not a square angle or a straight section on a stave. They are not only angled to form the radius, but the pieces themselves are curved (in both axis!).

Was thinking I could maybe do one edge (outside of the curve) with a round over bit in the table, and just not set it full depth. Ie, I'd only get a partial radio because the bearing will register against a surface beyond vertical of the bottom edge. Bearing would ride against outside of stave with side (1") of stave on the table. Not sure that would work for the inside curves though.

Any ideas?

How much of a radius are you talking about? Sounds like a hand tool job.

I'd be happy with 1/4"

Try a spokeshave or a compass plane.

Thanks. Yeah, that worked, but it's almost more work than just putting 80 grit on the RO 90 and sanding them round. I was hoping for some sort of one pass on the router solution.

really? for a 1/4" radius? a round over plane may work as well. such as something like this...

That looks like just the ticket ! Had forgot about those things.

These look neat. If used as shown in the picture against the grain couldn't you end up taking a bigger chunk out?  I would think you would want to use it in the opposite direction.

I have used those and you do need to be conscious of the grain or you risk tear out.  Make sure they are very sharp and proceed slowly.

The sandpaper idea on a cork-faced block is another approach that I would consider.  Fast and controllable.  And priced right.

Definitely watch grain direction they will gouge if you're not careful. But they are handy for quick noiseless dust free round overs.

There is a way to it with a router with the aid of a jig but I'm just not sure what the jig is like. I saw a router jug made in woodwork magazine a long time ago and can't remember the what the jig looked like
