ET sander will mimic the opposite edge of the stock which is lying on the conveyor belt Because of this it is important for the stock edge to have been ripped at the proper angle to the face before the sanding process When edge sanding stock that is less than 3 4 wide or more than 2 high it is good procedure to stack and clamp several pieces together to prevent them from slipping or tipping Sanding Imperfect Stock When sanding stock with a cup or crown place the crown up This will stabilize the stock to help prevent tipping or rocking during sanding After the crown has been removed and the top is flat turn the stock over and sand the opposite side To avoid personal injury take special care when sanding stock that is twisted bowed or otherwise varies in thickness from end to end If possible support such stock as it is being sanded to keep it from slipping or tipping Use extra roller stands help from another person or hand pressure on the stock to minimize potentially hazardous situations Face Frames and Raised Panel Doors It is very important to have the proper abrasive contact when doing this type of sanding If the sander is set to take an excessive depth of cut the result can be a gouge or dip as the drum goes from sanding the rails at full width to 17 sanding just a few inches of width on the stiles To prevent this problem make sure that when using abrasives finer then 80 grit the drum is in
