Here is a tip for flush setting. Make sure you use a lubricant while you are drilling your seat AND on top of the the stone prior to burnishing. Lubricating helps protects the stone and helps the burnisher glide smoothly. I also keep my burnisher perpendicular initially. I’m using @pepetools_usa Pepelube (I’ll link in my TOOLS highlights) but you can use other brands as well!
