I’ve recently bought two gouges that need some love. I’ve found Paul’s old blog post on restoring a gouge as well as Joseph’s video on sharpening, so I have a good idea what needs to be done to get them in working order.
One thing is not clear to me though. If I look at the cutting edge perpendicular to the length of the gauge I see that the edge is somewhat concave. Is this normal for a gauge? Instinctively I’d grind them square & straight, but never having used one I thought I’d check here. And if it needs to be concave, then by how much? Is my example about right?
I’m not much of a carver, and know more about chip carving, but what I was taught in my one relief carving class is that usually gouges are sharpened straight across because doing so give you better access into corners. For some work, though, people would sharpen with a convex shape, like a (slight) fingernail, e.g., pattern carving. If that were my gouge, I’d grind straight across to get the chips out. I’d ignore the bevel, and grind both nearly perpendicular vertically and square across. This will give you a thick, blunt edge, but you are less likely to burn the steel while getting rid of the chips. Then work carefully to restore the bevel.
Thanks guys, I’ll square them up. I’ve some other projects ongoing at the moment but Ill post progress in due time.
