Ok please note this is not a tutorial. Shown at real speed except the sanding which is speeded up. Using a 1” Thompson tools negative scraper with my preferred grind. Things to note: I use the tool width and length of bevel to aid measuring where the transition points are. When using the dividers make sure only the left hand point touches. NEVER plunge the scraper into end grain. The width of the square section is marked by a pencil mark I can see when spinning. Sorry it’s not a very good angle
