This forum is for questions about the physical preparation of parts before or during finishing, including grinding, polishing, buffing, honing, vibratory finishing, deburring, shot blasting, and related surface preparation methods. If you need a better surface finish, need to remove scale, or are trying to understand how mechanical prep affects appearance, adhesion, roughness, or performance, this is the right place to ask.

This forum is for questions about keeping finishes out of places they do not belong, including masking, plugging, capping, taping, stop-off lacquers, waxes, custom fixtures, and reusable tooling. If you need to protect threads, bores, contact areas, sealing surfaces, or selective finishing areas, ask here.
