Topic tags/keywords: sharpening question

I have several older carbide-tipped blades that I can resharpen and return to service. I was curious if it is practical to reshape the teeth profiles from ATB to FTG, or if the idea is dead in the water. I would appreciate comments on whether there are safety issues I should be concerned about as well as general comments. I don’t want to end up in a future episode of America’s Dumbest Ideas. BTW, I do have a Foley Belsaw Auto Sharp and grinding wheels for sharpening circular blades.

Carbide tipped doesn’t ensure quality. If it was a quality blade to startwith and there’s sufficient carbide left, it should be feasible if a flat top grind will suit your needs.

Whether or not to do it yourself is a separate question. It doesn’t cost much to gain access to some very expensive equipment and the expertise to run it. My view has always been that I wouldn’t touch my expensive blades myself, and the cheaper blades aren’t worth the effort…on the other hand, if you have the machine you could always experiment.

Thanks, knottscott. I agree with you about expensive blades but I have some old blades that I’m not using and need resharpening anyway. I probably will try an ATB – FTG conversion as an experiment. I just wanted to make sure that it wasn’t a just plain dumb idea.

If you have a local blade sharpener, maybe ask if they will do it. If they say no, then it’s probably a bad idea.

Good thought, Rick. I don’t think we have a local sharpener but I’ll ask around.

Changing from ATB to FTG removes a lot of carbide. I don’t think you can use the Foley, auto sharp (sharp all?). Isn’t that for non-carbide blades only? You need diamond to sharpen carbide. I have a Foley model 310 carbide grinder that is designed for that purpose.

Good point, Ron. I did get a bunch of grinding wheels when I got my SharpAll and I haven’t really inventoried to see if I might have a diamond wheel in my box of goodies. Thanks for the comment.

Plan change: If I don’t have a diamond wheel, I’ll take a non-carbide ATB blade to practice a FTG conversion.
