Thread: Removing a frown with the Dremel

After watching Bill fix a tapered blade with his benchgrinder, I'd like to try grinding out some frowns with my Dremel. I know this is a major "do it at your own risk" approach, but I'm hoping to pick up some tips if anyone else does this.

What type of bit should I use? I'm thinking one of the orange grinding stones...

How should I angle the blade? Should I run the stone lengthwise on the edge or perpendicular to it?

Thanks,
Josh

The orange grinding stones are too soft for that. However Dremel has a special grinding bit that you can pick up. I got mine @ WM. Here are some good reasons not to do this:
1) Even if you remove the frown, you'll have to establish a new bevel, on the level with the narrowest part of the blade, therefore you'll need to hone down that part anyways.
2) The speed of the rotation can overheat the edge, thus killing the temper.
3) Sandpaper cuts fast enough not to resort to desperate measures

I won't be getting my hands on a Dremel until around May. I took the frowns out of two of my restoring projects using my Hand American bench hone. Instead of laying the razor flat like honing I put it up on edge like I was going to cut my hone in half. I carefully sanded back and forth with 320 paper until I could set it on my glass plate and see no light. It did not take long but it sounded like nails on a chalkboard. Good luck with the Dremel Josh.

Done both tool and hand - what can I say, this can get extreme.

My daughters had a blast watching the sparkle rain off the Dremmel They still think I'm cool like that, and we all know this is going to change in some time so I enjoy it while I can

Dremmel is not a good idea, indeed. Can be done, and not sure that temper is lost, but setting the edge after this is a, a ... well - tough.

Go with the sandpaper

Maybe I'm not visualizing this correctly, but it seems to me that by the time you got the heel and the toe sanded down even with the center, then the edge would be thicker at the heel and toe than at the center, which should still be sharp.

...or, am I missing something here?

Lou, you are seeing it absolutely correctly. An easier-to-understand reiteration of my point #1

Bill Ellis has a lot more variable speed control over his grinder than anyone will have with a Dremel. Use sandpaper, it always works!
