    The light and dark on this micarta is caused by what? It's all a full flat surface. 20191124_154619.jpg The black stays black and smooth no matter how much I sand it down. The part that looks sanded was sanded to 2000 grit I'm dealing with millimeters so I'm unable to continuously sand it down. Any thoughts as to what I'm doing wrong or might be happening ? What can be done here? 20191124_155343.jpg

      To me, it looks like the white-ish spots may not be fully saturated with epoxy.

      Will it darken if you wet it.

      Maybe the angle of the threads? Kind of like curly wood grain.

      Is the face of the slingshot completely flat?
      If not you could be sanding in to the other layers today of the micarta.

      This is the second pass of sanding I've done starting from 220 up to 2000 grit. It is flat. I'll put a ruler on top of it in the morning to get a more accurate view. Although it's pretty much the same looking now as it was on the first pass of the sandpaper.

      Each layer of cloth is separated by a little resin. The white is the cloth close to the surface while the dark spots are resin. No matter how perfect the material is made, the cloth is floating in resin and will not be microscopically level. For most micarta uses, this is never a problem. When you do precision finish work, it can show up like this. There is nothing wrong with the material. Sand down one more layer, work down to wet sand at 1000 grit and then buff at 1800 RPM with white polishing compound.

      I think that's what happened? I used a square orbital sander. With such a small space for the orbital to sand on being the slingshot The orbital wasnt able to get the proper sanding strokes needed
      Given the effect on the surface

      I agree with DSIL and BigDH. I've made cloth micarta before and had the same look. That's why I started making construction paper micarta. You get a much more uniform look plus depending on how you stack the paper you can get some cool color gradients on the edges.

      I just hire Drew Bilbrey...because I cannot make micarta...not even the paper kind.

      Drew was kind enough to take on that part of a super secret project that will be ready in March 2020.

      I am starting now so I will be on time.


      Take care all you fine folks.

      This wasnt handmade micarta. It was store bought. I think it's to small a space for the orbital I'll do it different with the next piece
