    Increasing surface coverage and PPI

    Hello everyone, Sorry for the lack of answer, I was quite busy as I recently finished my engineering degree and I had a few job interviews lined up (and still have a couple more to do). I probably won't be able to scrape until this week-end but I'll send picture of my work asap. Regarding the...

    Increasing surface coverage and PPI

    This is something I thought about during my scraping sessions but I'm not sure how to avoid this over scraping thing. I feel like I am bound at some point to overscrape by having scrape marks being right next to each other after multiple scraping passes when trying to scrape in the checker board...

    Thank you for the feedback, I'll try the stoning method although I don't have proper flat stones. Right now I use very fine swiss watchmakers files to deburr but I will try to lightly draw file across the surface with a slightly coarser file. Regarding the splitting it's not always feasable as...

    Increasing surface coverage and PPI

    Hello everyone, I have been scraping a little bit for a couple of years but I recently got serious about improving and obtaining a higher quality surface finish. I am still very much a beginner and the information on this forum has been invaluable (and also the videos made by the students of...
