(Jethro scale) 4/0 is equivalent to 180/220 grit P-grade Micron scale - Developed by 3M where grains are measured by particle size in microns and the lower the number called, the finer the grit. I.E. A 24 micron is equal to an 800 grit P scale whereas a 740 micron is equal to a 24 grit P scale.

79 Great Tips III When sanding picture frames, sand the rails first, then sand the stiles. When sanding picture frames, sand the rails first, then sand the stiles. Final sanding on hardwoods is normally accomplished with P120 to P180 grit. Final sanding on hardwoods is normally accomplished with P120 to P180 grit. Final sanding on softwoods is normally accomplished with P150 to P220 grit range. Final sanding on softwoods is normally accomplished with P150 to P220 grit range. When applying a water based finish or stain, moisten the wood with a wet cloth. This raises the grain. Allow the surface to dry and sand with final grit. When applying a water based finish or stain, moisten the wood with a wet cloth. This raises the grain. Allow the surface to dry and sand with final grit.

80 Troubleshooting Abrasives Loading Quickly *Excessive sanding pressure. *Inadequate or excessive dust extraction. *Excessive belt speed. *Moisture content of wood too high. *Grit too fine. *Improper sandpaper for the application.

81 Troubleshooting Abrasives Dulling Prematurely *Grit too fine. *Excessive sanding pressure. *Wrong product for application. *Belt too stiff for application.

82 Troubleshooting Streaking of work piece * Belt loaded or dull. *Sanding pressure too high. *Dust on work piece. *Overloading due to glue lines or pitch material on work piece.

83 A Final Word Sanding and finishing is the least favorite steps when surveying woodworkers… Sanding and finishing is the least favorite steps when surveying woodworkers… …But are the absolute most important steps in a project. …But are the absolute most important steps in a project. Remember: First impression of your project is the most important! Remember: First impression of your project is the most important! First thing seen: QUALITY OF FINISH. QUALITY OF FINISH.

84 Remember: THE BITTERNESS OF POOR QUALITY IS LONG REMEMBERED AFTER THE SWEETNESS OF LOW PRICE IS FORGOTTEN! Klingspor Abrasives = Top Quality Remember: THE BITTERNESS OF POOR QUALITY IS LONG REMEMBERED AFTER THE SWEETNESS OF LOW PRICE IS FORGOTTEN! Klingspor Abrasives = Top Quality
