It's been a while since I posted anything regarding my long and arduous journey into the world of scraping, but I've not been totally idle. Some email communications with Richard King regarding the "Technique 40" from the Biax book have been very helpful. Using these techniques I have scraped my practice piece (victim?) as shown in the attached pics. Both show a decent PPI count, but I don't feel like the "Percentage Of Contact" is as high as it should be. How should I try to improve that? My first thought is to work on it with a whetstone until the size of the blue spots increases to the desired percentage of contact, but everything that I have read says that whetstones are to be used for deburring post scraping and nothing more. Any advice?
