The new blade on my 24 inch saw has stopped cutting, on a large piece of Biggs Jasper. The feed works, the rock has not shifted. My assumption is the blade needs sharpening (or to be dressed). Any suggestions on the best way to do that?
Thanks
Henry

I have had good luck peening the blade on my 24" Frantom. I use a mill bastard file and lay it across the blade perpendicular to the blade then tap fairly gently with a hammer. I work my way around until I have covered the entire circumference of the blade.
I have also had good luck removing the blade and turning it around so the diamonds are running the other direction. This pulls the metal back off of them and allows for contact with the rock.
Good luck with your efforts.
Bill

I do this to my tile saw blades when they start to get rounded. I tap directly on the blade with a ball peen hammer. I've not tried striking something else, like a file, but I can't see why that won't work. As far as dressing, some use a red brick and cut into that. I use a tile rubbing stone that can be found at most places where tile supplies are sold. There's an old article that is stickied here in the forum. Start on page 5. forum.rocktumblinghobby.com/thread/52499/general-lapidary-info It addresses both of your questions. |
