I cut a little notch into the dowel with the table saw.
To do this in a save way,please look at the picture.
Step 2: Glue the Dowel Onto an Old Saw Blade
I filled the slot of the dowel with epoxy
and glued the saw blade into the slot.
Step 3: Glue Sandpaper On
Cut a piece of sandpaper and glue it on the dowel,
the seam on the back.
Step 4: Setup
I have a work surface for my jigsaw and place a board with a hole above it.
But you can also mount the jigsaw directly on a board,
Step 5: The Result
Now turn the jigsaw on and sand what ever you want.
