Over sanding
Do not over sand the product. It is a waste of time and there for money.
- Place piece face down on the sanding table.
- With the ORBITAL sander square to the face of the piece, sand all 4 edges with 150 grit to remove machining marks.
- Feel the edge for any bad machining.
- If smooth, sand all 4 edges with 320 grit to polish.
- Ease all 4 corners to a 1.0mm profile with 150 grit.
Sharp | Eased |
---|---|
- Sand back face of piece with 320 grit. 2 passes will normally do.
- Run 150 grit around the eased profile to even it out and knock off the sharp points.
Sharp | Eased |
---|---|
- Make sure it is labelled, and that the label will not get hidden with paint.
- Flip piece to face side up.
- Sand face with 320 grit, looking for imperfections and glue.
- Place on a spray cart or gently into a red cart for later.
