I’ve been woodworking for 30 years and never realized how sloppy I’ve been about grinding and sharpening until I was asked to teach teenagers how to sharpen here at our school for woodworking in Mexico. After a lot of research I decided to go with the Eclipse honing guide on waterstones and grind to a 25° for both chisels and plane irons. I found two handy articles on an easy way to set up the honing guide, but to set up the honing guide for this angle I get a very different result than what I found in these two articles.
Christopher Schwarz says: The bottom line is that if I put the thinnest plane iron in my honing guide and set it to extend 1-1/2” from the front of the jig, it will sharpen the tool at 30°. If I put the thickest plane iron I have in my shop in the honing guide and set it to extend 1-1/2” from the guide, then it will sharpen the tool at a little more than 31°. Does that matter? No, no and no.
The Lie-Nielsen article recommends
But I get 25° (checking with my brass Richard Kell angle gauge) by setting my honing guide 2 5/8” from the edge. That’s a whopping ½ inch difference.
If anyone out there has a honing guide and a digital angle finder, I’d appreciate it if you could do some checking and let me know how far from the front of the jig you set a blade to get a 25° angle.
