I have a good setup for sharpening straight plane blades and chisels. I don't see much information on sharpening curved blades. Would someone recommend an article or video of same?

Double Bass Sharpening Curved Plane Blades
- Thread starter Ned Smith
- Start date
I used to grind a radius on end mill flutes to cut a fillet instead of a square cut. I used a tool grinder with a pink stone on it. It had a jig you could use to help get the right angles, but after a while I could get what I needed by hand.
I’ve seen some tool grinders made to both grind and touch up wood lathe tools.
I’ve used the scary sharp method to deck wet fuel engine blocks and motor mounts on rc race cars. A piece of tempered glass with various grits of carbide paper taped to it. It is excellent for flattening and honing straight blades, and with a little practice could be used to touch up curved gouges and such.
Last, my grandad the pattern maker had a set of various diameter stone rods he used to keep his hand carving tools keen.

If you like fixtures & guided shapes, the wood-turning community has a number of setups to fixture putting curved edges (such as the "fingernail grind") on gouges, which should be adaptable to doing the same on flat plane blades if winging it doesn't work well for you. While there are commercial versions, they all follow from home-made versions you can still make if that suits your mindset.
As far as I know they are also the source for the hack of using a belt sander running "upside down" (belt running away from you) with an AlZn belt as a rough grinder with great speed and long wear, and no radius to it if you run on the platen.
