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. One chattertool tip (RS220) has a straight and a pointed end, the second (RS221) has a convex and a concave half-round end.
Chatter patterns are created by causing the spring steel tips to vibrate against the wood can be changed by altering the variables:
- The type of wood
- Whether working on, below or above center
- The speed of the lathe
- The amount the tip extends from the chattertool
- The shape of the chattertool tip
