LEFT HAND THREAD SCROLLS FOR DIY TIMERS

THESE TWO PRECISION MACHINED SCROLLS ARE SIMILAR TO WHAT WE USE ON OUR PRODUCTS. IF YOU ARE MAKING A DT TIMER FROM A TOY MECHANISM, YOU NEED SOMETHING LIKE THIS. YOU WILL NOTE WE HAVE ADDED THE DISK WITH A RED MARKER LINE UNDER THE SCROLL. THIS DISK IS FOR USE AS A POSITION MARKER AS IT IS NOT STRONG ENOUGH TO SURVIVE A FORCE ON IT.

• THE HOLE IN THE CENTER HAS A DIAMETER OF ABOUT 0.046 INCHES. YOU CAN DRILL IT OUT TO WHAT YOU NEED.
   

• THE DIAMETER IS ABOUT 0.310 INCHES
   

• THE LENGTH IS ABOUT 0.45 INCHES
   

• THERE ARE FIVE + TURNS

THE "A" TYPE IS PRIMARILY FOR WHEN YOU WANT TO REST A WIRE IN THE THREADS, SOMEWHAT PERPENDICULAR TO THE SCROLL.

THE "B" TYPE IS MOSTLY FOR WHEN YOU WANT TO PUT THE TIP OF A WIRE IN THE THREADS. THE GROOVE WALL IS BASICALLY STRAIGHT.
