Sharpening thumb plane blades
…can be a bit of a pain, which is why I made this little gadget.
I use those minature violin makers planes quite a bit these days – for shaping braces and for shaping the bridge after it’s glued to the top, but getting a good keen edge on those tiny blades can be a bit fiddly.
This mahogany jig helps hold that little blade at a set angle. And the dowel that sicks out acts as a pivot. It’s not perfect – it doesn’t do everything for you. There is still some skill required, but at least “the main” grinding angle is fixed. Then it’s a case of sweeping/rotating the blade on your stone keeping an eye on the curve you’re making.
If you know of any simple ways to improve the guide, drop me a line and I shall share it on the blog.
