newly drilled thumb slugs

what's a good way to rough up the surface of a newly drilled thumb insert. it's real smooth and on the slippery side. i'm trying to get away from thumb tape instead of opening up the hole size for a fit.....

Pin pointing the exact feel you're looking for is probably going to be a trial and error process. If you use a rotary tool, you'll be changing the texture of the entire hole.

You could etch the slug by hand. This would allow greater control over the process. I've seen people use a nail to scratch horizontal grooves in their thumb hole. To me, that's a little extreme. The use of a small piece of sand paper or drywall screen is probably a better choice.

Start with 320 grit. At first, concentrate on the area where you might put a piece of tape. Move the abrasive sideways (not up and down). Change grits until you achieve the feel you like best.

I didn't want to use my rotary hole sander , so that's a good idea just to sand the thumb pad side only. usually my thumb hole is drilled bigger but this one that my pro shop drilled is almost perfect in size and I'm and trying to get way with the least amount of tape.

You can also try slowing down your thumb pitch, and using less bevel. Personally, I smooth out my thumb holes so they are like glass, and have enough room for a couple of pieces of white textured thumb hole tape and change it frequently, every six games at most. I try and line it up on the front side of my oval angle and layer it for more than 1 piece.
