I was finish turning a rock hard Ca. Live Oak platter using a freshly sharpened round-nose scraper with a burr. Although I was getting nice fluffy or wispy shavings, I was still getting a little tear out and some minor catches. So I tried rotating the scraper as it was introduced - - maybe at an angle between 45 and 75 degrees. I was pleasant surprised that it just about eliminated all of the catches and tear out. But holding that angle was a little tricky and I had some tool marks.
Is this kind of a standard thing to do (rotate scraper) when addressing tearout and catches??
BTW, sanding the live oak is a PITA because of its hardness. Lots and lots of sanding - - not a lot of sawdust or removal of tool marks. Kind of like trying to sand a metal file to remove the teeth.
