S3, 64mm Pulley Plate

The 64mm Pulley Plate is one of two pulley plates available in the S3 Ecosystem. Two of these plates in conjunction with standoffs, screws, and a nub create an effective and robust winch, am-3728 (coming soon). 

It has a central bolt pattern for an AndyMark XL Nub (am-3441a) or the 0.770 in. bolt circle used with the Actobotics building system. There are three different bolt circles where you can attach standoffs. The different bolt circles can form different diameter pulleys from 32mm to 64mm. The outside diameter of this plate matches the root diameter of a 40 Tooth Ninja Star Sprocket (am-3285). This allows it to be used as an idler chain guide.
