I cut the attached image in edge glued Aspen. I had no idea how fibrous this material is and I’m wondering if there are any suggestions to cleanup/sand some of the cut surfaces.
Someday I’ll be able to contribute back to this sub, I hope!
Short answer from me, I use a light or medium stiff brush. You could use sand paper but those areas look pretty close and it turn into a real labor of love trying to fold it just right to fit.
