I've been taught to set the compuond at 29.5 deg when cutting threads. I understand this is so the back side of the tool dosen't rub and cause chatter. I wanted to get a visualization of this so I drew up the angles on cad. Now I'm only more confused as setting it to 29.5 deg would actually cause the back off the tool to have more contact than if it were set to 30 or 30.5 deg. I've tried it set at all angles with no noticeable difference. Maybe you guys can clear up the reasoning as why you set it to 29.5 deg.
