Woodshop Tip

Choosing the right sandpaper for power sanding. Sandpaper is available in "open coat" and "closed coat" styles. Open coat abrasives have more space between the abrasive particles than closed coat abrasives. As a result, closed coat papers cut more aggressively than open coat papers (and rightfully so, since they rely on elbow grease). Open coat abrasives, on the other hand, won't load-up as rapidly as closed coat abrasives. So ... when power sanding, always look for open coat abrasives.
