Honing carbide inserts with Silicone Carbide sandpaper What Grit to use??

[randyrls]

I use Silicone Carbide sandpaper to sand blanks and have small diamond hones to hone carbide inserts. The diamond hones are getting tired and I was thinking about gluing silicone carbide sand paper on the hones to refurbish them.

Does anyone do this with SiC paper and what grit do you use? My hones just say Fine, Medium, and Coarse.

It's COLD here in PA!!! I got out the heater and need to run it to keep heat in!!! Stay Warm folks!!

What about gluing different grits to something like Masonite as a "test"? Scrap Masonite is plentiful here and if that works, wouldn't it work over the credit card files?

Great idea, by the way!

Randy, the above link may help. Good stuff to use and if you put it on a flat glass sheet then the performance honing is that much better for the carbide inserts.

Andy; There is a system called "Scary sharp" that uses flat plate glass as a base for sandpaper to sharpen tools. That's what gave me the idea in the first place.

I remembered that I have some MDF pieces stuck away somewhere. Bet I could use that. I have Craft Spray adhesive.

Isn't silicon carbide softer than tungsten carbide? Kind of like sharpening a chisel with jello?

I use granite and diamond paste,depending on to what level you want to hone/sharpen you can get the paste in many different meshes. MSC has a good selection here is a link for examples.
