Hook & Loop Sandpaper

Although hook & loop sandpaper is convenient and easy to install, care must be taken not to overload it while sanding by taking excessively heavy cuts.

Excessively heavy cuts will cause the underlying hooks and loops to slightly depress and deform under the sandpaper, resulting in small surface grooves and ridges on all subsequently sanded pieces. If this should happen, the only way to cor- rect the situation is to unwrap and then re-wrap the sandpaper around the drum to “reset” the hooks and loops.

Simply stated: DO NOT take excessively heavy cuts. If you need to remove material faster, switch to a coarser grit of sandpaper.

Choosing Sandpaper

There are many types of sanding belts to choose from. We recommend Aluminum Oxide for gener- al workshop environments. Below is a chart that groups abrasives into different classes, and shows which grits fall into each class.

Grit

Type

60Coarse

80-100 Medium

120-180

Fine

 

 

220

Very Fine

The general rule of thumb is to sand a workpiece with progressively higher grit numbers, with no one grit increase of more than 50.

The Model G1066/G1066Z/G1079 allows you to place two different grit sandpapers on each drum.The first drum should have a coarser grit than the second. Usually this translates into com- binations of successive group types. A common selection for stock that is planed before being sanded is a 100/150 grit combination.

Ultimately, the type of wood you use and your stage of finish will determine the best grit types to install on your sander.
