AWSI Also manufactures an automated "SPOTTER". The AWS-BB5 is a totally automatic Bowling Ball Spotter, which moves the ball from an input queue to the scale, finds the heavy spot, marks it, and stores the "top weight" and "total weight", and moves the ball to an output queue, all in under 30 seconds. Repeatability of the spot in a production environment is under 0.100 inch.

What is it?

• "Top Weight" is a heavy spot, not at the center of the ball but near the outside edge.

Why is important?

• The heavy spot enables your pro shop to drill the ball for your finger holes, causing the ball then to be balanced, no heavy spot.
• Also, they can control the location of the heavy spot, and give you a better hook.

How does it get there?

• The manufacturer of the ball will "cast" the ball with a heavy spot on purpose. Enabling them to do many clever things with that heavy spot.

How do they find that heavy spot?

• Manufacturers of bowling balls used to "float" the balls in air and the "heavy" spot would drift to the bottom,, but accuracy/repeatability was no better tham 3/4 of an inch. Sometimes the air cushion would actually move the ball a bit off center.
• Some "floated" the balls in mercury... no better results.
• Some used hot liquid salts... no better.
• Top manufacturers now use our Automated Scale Spotting System. Nothing is more accurate. It repeats to less than 0.100 inch.
