- 1). Draw a rough sketch of the profile that you wish to sand on a piece of paper with a pencil. If it is molding that you intend to sanding, trace the end of the molding directly onto the paper.
- 2). Cut the drawing out with scissors. Trace the paper cut-out onto both ends of the block.
- 3). Hold the block against the stationary sander. Work the top of the block down to meet and match the drawing on the ends of the block. If you can't get fine enough detail to match your drawing on the stationary sander, use the sides of a bench grinder wheel to add the sharper detail.
- 4). Hold the profile block up against the profile you wish to sand. Check to see where the two profiles fit together. Use a pencil to mark the places where the profiles don't match. Use the grinding wheel to grind the detail closer so that they fit together as tightly as possible.
- 5). Peel the back off of an abrasive sanding disc. Place the sticky side on the profile and smash the sanding disc into the profile with your fingers, forcing it down into the cracks and curvatures until it sticks. Trim the outside edges of the disc off with sandpaper.
