I do a lot of fretwork, and every time I threaded the scrollsaw blade into a new hole, I had to reset the hold-down. The problem was adjusting the hold-down tension so the work did not jump but still slid smoothly.

My solution was to place a drill-bit stop collar over the shaft of the hold-down assembly. When I have the hold-down tension set just right, I slide the stop collar down so it rests on the arm. Then I tighten it. The stop collar allows me to reset the hold-down in just the right position after each blade threading
