ShotPuck model SP1 rev-A The 3D Printed, Lead Shot Loaded Record Weight!

The ShotPuck SP1 rev-A is a record weight that features 5 chambers loaded with #9 lead shot. In fact 83% of the ShotPuck's total mass is #9 lead shot. Each chamber contains precisely 54 grams of the shot. Total weight of the assembled record weight is 326 grams. (.72 lbs) Below is the explanation for the concept of this record weight.

What is the purpose of this record puck? (also known as a record weight)

Q: We might just as well ask the question; what is the point of any record weight?* A: to dampen vibrations running through the record as it is being played. Q: why lead shot chambers? A: Very much like a sand box, the individual lead shot vibrate against one another when stimulated by an external source of vibration. This implies that the individual shot act as a conduit through which vibrations travel. However, because the individual shot are in intimate contact with a large mass of shot, there is not enough energy coming from the source stimulant to force the vibrations to pass completely through the chamber. Ergo vibrations go in, they are dissipated and die within the shot chamber. When this theory is executed properly within a record puck, the end effect is that the reduction in record vibrations result in a cleaner sounding playback. This should also result in a measurable improvement in the s/n ratio.

*(Record weights are often nick-named a 'puck'. because the size and shape often resembles a hockey puck)

Product Notes:

This model is derived from the Shot Puck Model One in that it retains the overall shape with five cylindrical shot chambers arranged in a five point star configuration. It differs from the Model One as follows:

The shot chamber volume is increased to carry a larger shot load which results in a total Puck Weight of .72 lbs vs .52 lbs for the Model One.

The external body detail over the spindle pin bore is altered in shape to make a more efficient use of the ABS resin material while maintaining strength.

This model implements a post-print procedure which results in a much smoother external finish. The process is sometimes called Acetone Vapor finish. The acetone vapor process increases the total manufacturing time requirement by an additional 10 hours. The visual impression, I think, makes the added time worth while, and also can eliminate the need for paint At this time the standard finish for this model is texture black enamel. Natural finish pucks (no paint) will be made available separately, soon.
