Dynamo - Copper and Aluminum Spinning Top w/ Super Grip Stem

This Dynamo is constructed with a copper (CuTe) outer ring and has a super grip (knurled and milled) aluminum spindle. It has a tungsten carbide (TC) bearing for it's spin point. The top has a brushed finish and the copper will develop a patina over time. This Dynamo was crafted on a CNC lathe followed by hand finishing. The stem was knurled on a manual lathe then milled to give you the super grip appearance.  While spin times will vary with practice and experience, the copper and aluminum Dynamo had 15 minute spin time during performance testing. All Kemner Design tops are designed, crafted and finished in my shop. I personally test all of the tops for performance prior to shipping them to you. The Dynamo comes with a personalized owners card that proudly displays the name of the top, birth date, material and bearing used, serial number and maker’s signature. Tops can have multiple functions; they can be used for stress relief, educational purposes, display or to play with.
