I recently saw a posting( that I have lost ) with a picture of a
sanding disk that had a bearing on the bottom for "pattern sanding". I
have searched several Tool Sites and did a "DAG" to no avail. Anyone
familiar with this attachment and a dealer/supplier. ? Could sure put
this to good use! Thanks
