I feel the same thing as Tom Silva said at minute 2:20 - Working with your hands and building something. This is why I make part of my seminars learning how to hand scrape. Using the Biax Power Scraper is using an electric power tool, but your steering it with your hands. You have to learn hand and eye coordination.
I tell my students hand scraping is like shooting a bolt action rifle one bullet at a time compared to using a machine gun where you shoot automatic many rounds or scraping using a Biax. I can recall like Mr. Silva working with my Dad who taught me to scrape in the basement of our house, when he brought home straightedges my brother Tom and I could learn to scrape on when we were in our early years, maybe 8 or 10. I recall working summer vacations with my dad at Control Data and Onan on large machines scraping by hand. We didn't use the Biax until 1972 when we were rebuilding a Giddings and Lewis Boring bar for Kurt Mfg. The ways on the base were 12" wide and 25' long. Prior to that we hand scraped those large machines. Like Tom, I love to teach scraping and share what my Dad talk me. Working with my hands - teaching the readers - having my students teach on You Tube. What a legacy .
The thread about Scraping a Straightedge is how I learned to scrape and it is easy for me to recognize where it is high or humped as I scraped by hand for more then 10 years before going to a Biax. In the early years we only roughed with the Biax and finished with a hand scraper as back then Biax didn't sell finish blades. Many of my students say they will never buy a Biax as they are so expensive, but after using one in the class they end up buying one. Many still say they are only good for roughing. Those who say that have never been shown how to scrape using the proper blades and techniques. One doesn't get as much chatter by hand, I will admit that. One can increase productivity by 50 to 75% using a Biax Power scraper.
