I ran across a picture in Rocklers newest catalog that got my interest. It was for holding the sanding disks for orbatal sanders. Was only $29.00. But looking for another project anyway ...... This seemed like a good one for me to do. I have a minimum space to work with,but found it would fit in the same place as my sanders set. Also makes it a snap to line up the holes with the ports on the sander. As the dowels are in same pattern that holds the sand paper. Just load them on with the sandpaper down and your good to go. Thanks to the picture in Rocklers catalog....a good addition to my shop.
