Myford 7x7 - cross slide - finish scraping flats

Goal/objective: Break up the surface/establish a nice checkerboard pattern/20 PPI/flatness within 1/100mm or better.
So far finished finish scraped 2 cross-slides, expect to do the rest within the next days (hence the photo you see where the cross-slides are stacked behind one another shows them in "semi-finished" state.. I just thought it was timely to do the video now in conjunction with the rest of the cross-slide "documentation")
Used the BIAX power scraper for one and hand-scraping the other with the touch-and-lift on the forward stroke method. The rest will be power scraped, but then I have a means of comparing results and also see over time if they differ as a result of of wear will have (if hobby usage will wear them to any appreciable degree)
