Greetings! Could I get some advice on the correct usage of the chatter tool to produce various chatter patterns on end grain work? Is the tool properly held like a scraper parallel to the ground or is it used at an angle? Also, I was wondering if the chatter blade actually flexes slightly or does the tool rattle up-and-down or perhaps side-to-side in its holder. It's sold by multiple manufactureres including: Stewart, Sorby, and Crown. Much thanks.
