Thanks for the encouragement. I've never done any presenting to camera before I did these videos, and my No.1 aim is clear teaching, that's more important to me than anything else.

In that regard you have done an amazing job. To the point but also explaining why you do what you are doing.

You use a slip stone or round cutter work the concave bevel in sections then flat the back on a normal stone as you would any planeiron.

+ghostzart All bench planes usually have the corners ground off. Further, a fore plane like that usually has a mild radius ground on the plane, so the plane iron is rounded slightly. There wouldn't be any corners to mar anyway. Finally, the edges plane aren't in contact with the wood anyway, as he's planing the corner of the piece.

Ovolo comes from the word 'ovum' or egg, which is also related to oval. An S-shaped moulding is called an "ogee", or a "reverse ogee", depending on whether the concave or convex surface comes first. It's also sometimes called a cyma. I hope that helps. You might like this link about molding shapes and names. thedesignersassistant.com/2011/11/27/will-the-real-ogee-please-stand-up/
