I found AO belts gum up less and work better and last longer than Zirc or Ceramic on handle materials as well. I try to find open coat belts; sometimes the closed coat belts seem to clog up more and dull quicker? I used one set of 120, 220, 320, 400 and 600 AO SuperNova 2" wide scalloped belts on over 20 handles and they are still cutting well. I often rough with a 36 and then clean up and contour with a 80 grit AO belt before switching to the scalloped. I go thru the 36 and 80 grits faster, but they are also grinding the tang down a bit, too and get gummed up getting all of the excess epoxy off the tang/scales too and grinding down pins.
Resin dust can be interesting! When I do my fabric based home made micarta handles with epoxy resins, the result is a very fluffy cotton ball like pile of dust that is about 3-4 times the size of the handle block itself! I imagine the resin dust is similar? Very puffy and fluffy? Or is it more plasticy and stringy like when working acrylic handle materials?
