One More Time - Which Abrasive Belts Should I Get?

12 posts in this topic

I know that this has probaly been bandied about many many times. But I am almost done with my Grinder in A Box by Polar Bear Forge. Yippee!

 

What belts should I consider buying and where should I buy them.

 

If it matters, I am forging 5160, 4140, W1,2, etc. Nothing too crazy.

 

going to run 2X72 belts although I think I could go up to 2x96 with this grinder. It has an adjustable arm.

Stick with 2x72 belts. I get mine from Super Grit . com. They have a large assortment, good prices, and great customer service. Fast delivery at a low cost of shipping. If you don't see it on their site call them.

 

I buy in ceramic; 36, 50,120, & 220, for steel. For handle material I get zirconia belts normally in; 50, 120, 220, 320, 400, & 600. For sharpening I get black silicone carbide in; 320, 400, & 800. I also get some other specialty belts which are very specific in use. I recently got a couple of 36 grit zirconia ones to use when making horse mat handles for a small utility line of knives I am doing.

 

The finish of my work is done mainly by hand sanding and that's a whole new world.

 

PS: I use ceramic because they last longer, and cut better.

I like the Norton Norzon plus Zirconia blue belts up to 220 grit then I switch to 3M micron belts for 400 and 600 grit. If I go past that I resort to hand sanding lubricated with WD-40. I think both Super Grit and USA Knife Maker Supply carry both.

I pretty much hand sanded my first and only knife, so i'm not above hand sanding. I am however excited about being able to shape my knives faster after forging. My little Home Depot 4X36in wood belt sander was killing me.

 

Hopefully my wheels will arrive in the next two weeks.

I was happy too when my clone 2x72 arrived. It makes a great difference in the way you work and the final product you get. When I hand sand I use Mobil One 5w40 as my lube. Works very well with a minimum of effort.

 

My favorite tool on my grinder is my small wheel adapter with a 3/4" wheel. I use it for tight curves and to texture handles.

I just bought some of the blue Norton zirconia coarse belts they're good and not too expensive.

I'm just beginning to understand the freedom that this GIB will allow me. I bought both platens. The standard platen and the adjustable platen that will have an 8 in contact wheel and 2 in idler wheel. I like the small wheel idea. Have to look into that.
