Ok- this may seem like a dumb question. But, I have a lot of TS blades. Most of these are fairly old, carbide blades of good quality. Have any of you worked out a way to determine just how sharp the carbide is on a blade, without mounting it in the saw and trying it?
I'm thinking of something analogous to testing a chisel by shaving your arm hair.
I'm on the verge of finally getting my SCMI sliding table saw on the air. Over the years that I've had this thing, I have picked up about a dozen or more blades, up to 16" that will fit this beast.
Fortunately, it will also run the same 12"x1" arbor blades that I run on my Powermatic #70 TS. And I have about a dozen of those as well.
The blade on my powermatic at the moment is a little less than perfectly sharp. But it still scrapes my fingernail when I drag it across a tooth.
I think I may get out a jeweler's loupe and look closely at the edges.
Along these same lines, anybody had any success with touching up carbide teeth? I once saw a diamond grinding wheel with holes in it so you could see exactly what you were grinding. The demo guy was hand sharpening a TS blade.
