Scroll saw sanding tool homemade

This is a simple scroll saw sanding tool for trimming of cut parts. I used an dull saw as a backbone of this new tool. Folded sand paper is glued to the supporting saw, pressed in the suitable clamp, and after that used in the scroll saw as a sander. This tool can be reversed upside down to utilize all length of the sandpaper.
Further improvements include gluing the cylindrical (pencil like) stick (with the suitable groove for saw). This stick should be layered with sand paper, and utilized for curved surfaces sanding...Attachment 27151Attachment 27152
