Sponsors and Curators The Museum of Yo-Yo History is a labor of love, and we would not be able to stay up-to-date with exhibits without the support of our sponsors and curators. Big thanks go to One Drop Design and Duncan for supplying us with their latest models, YoYoExpert for their help and support, and to Cody Orr, TotalArtist and YoYoBrothers™ for allowing us to use their collections! If you're a manufacturer, or just a big collector and you want to help support the Museum drop me at line at chimera@yoyomuseum.com YoYoFactory Grind Machine (plastic) Exhibit #1602 Type Production Shape Concave )-( Axle Bearing Color Translucent Black with Teal Packaging Boxed Construction Multi-piece plastic Response Silicon Ring Diameter 56.39mm Width 40.89mm Gap Fixed Weight 64g Estimated Value $$30 Condition Mint Owner Grahame Wright Compare The YoYoFactory Grind Machine is a polycarbonate yo-yo not to be confused with the original Grind Machine. The plastic Grind Machine is textured to allow for excellent grinds and features weight rings for longer spins. It also uses YoYoFactory's patented Hubstack Technology allowing for pull starts and insane finger spins. The Grind Machine is available in many different colors, shown here in translucent black with teal weight rings and hubstacks. It uses a standard C bearing and CBC broad pads for response.
