The chassis rotates on it’s spindle to allow you access for grinding on all 3 sides. Each side has a different span between the wheels for varying amounts of support (10, 8 or 6 inches). The longer the span, the less support the belt has, which results in a more convex grind. This is great for creating convex primary bevels or secondary bevels and sharpening.\u003c\/p\u003e\n\u003cp class=\"\"\u003eAnother great use is for improved surface finish while flat grinding. If you use the steel platen behind the 10” span, you can achieve high polish finishes on your flat grinds because the rubber belt reduces belt joint bump. This should greatly reduce hand sanding time. WARNING: if you do not have a water or air chilled platen, we do not recommend doing large amounts of stock removal against the hard backer because there is a risk of overheating and melting your belt.\u003c\/p\u003e\n\u003cp class=\"\"\u003eIf you have another use for the rotary platen, please let us know so we can communicate that with anyone who is trying to learn.\u003c\/p\u003e\n\u003cp class=\"\"\u003e\u003cstrong\u003eWhat’s Included:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-rte-list=\"default\"\u003e\n\u003cli\u003e\n\u003cp class=\"\"\u003eComplete Rotary Platen mounted on an accessory arm\u003c\/p\u003e\n\u003cul data-rte-list=\"default\"\u003e\n\u003cli\u003e\n\u003cp class=\"\"\u003eBlack Oxide Coated Steel Chassis (access holes for water or air lines to accommodate chilled platens.
