The problem with learning scraping is it's a technique based skill, like welding. Can you learn it by watching some videos and practice? Probably, but having someone who knows what they are doing looking over your shoulder and correcting you in real time might be more cost effective considering the time and money needed to figure it out yourself. And I will warn you, scraping is not a cheap bit of the hobby to get into (as if any of this hobby is). You can build a hand scraper yourself and get a low cost surface plate. Beyond that, expect to pay $10 or more per inch for straight edges that you will probably have to scrape in yourself. I haven't priced Biax scrapers lately, but I paid $600 (used) for mine about 10 years ago, and it was a good deal for what I got. New blades for the Biax run about $100 each. It's like any other aspect of this hobby, the further into it you go, the more stuff you will need to either buy or fabricate. I took Richards class, and it was quite informative. I recommend that being the first thing you spend money on if you want to get into scraping. You can also determine whether you really want to do it or not before sinking money into all the accesories I described above (although I recomend a surface plate even if you don't want to scrape).
