Chatter-Wave Prevention - Amano American Sanders American 12 Manual Del Operador

American Sanders Sanders are designed and manufactured to the most rigid tolerances. However, after a
finishing cut it is possible to see "chatter" or "waves".
The best guarantee to remove the chatter is to finish the floor with a
rotating horizontal sander, such as American Sanders's Sander 16.
To minimize chatter when using a belt or drum sander the following steps should be taken:
1) DRUM PAPER...insure the paper is secured in the slot, but not too tight. Paper that
is too tight will force the drum slot wider, leaving a "slot mark chatter" on the floor.
2) DRUM MARKS........are caused by the operator lowering the drum to the floor without forward tra-
verse. These marks should be removed by cutting at a 45 degree angle to the mark. Cutting
at the mark while maintaining the same path will only increase the mark depth and width.
