Chattertool patterns add a neat; random decoration on end grain like box lids. These are created by using the Robert Sorby chattertool which comes with two different double-ended chattering tips and a handy scraper cutter. Chatter patterns are created by causing the spring steel tips to vibrate against the wood and can be changed by altering the variables: the type of wood; whether working on; below or above centre; the speed of the lathe; the amount the tip extends from the chattertool; the shape of the chattertool tip This random nature enables the turner to produce some exquisite; yet unique decorations. Such decorations can enhance even the blandest of wood.
