I am completely new to scraping. I have never really scraped a surface but I understand the high level concepts. I am not trying to fully invest myself into learning all the tiny details, nor do I expect to have many projects that require scraping. With that being said, I'd like to have the ability to do a small amount of scraping to improve the fit and function of the machine tools that I own. They are all imports and not worth the effort to fully scrape in the machine, but I think a few passes on the various surfaces would make a dramatic difference in how the parts fit together.
My questions are:
My questions are:
- I've seen Sandvik, Biax, and Anderson scrapers for sale but they are large and fairly expensive. Are there any smaller sub-$100 scrapers for things like gibs and touchups that you could recommend. Maybe one day I'll take the leap and get all the scraping essentials, but for now having something to do some touchup would be great. I'm using a file right now, but I think it is a far cry from working as well as a real scraper.
- Can anyone provide a reference for how a blade should be ground? I have been using the end of a file to do some trial scraping but I find that it wants to skim and burnish the surface much more than it wants to cut. This is especially true of a positive rake. I can seem to get the negative rake tool to bite very slightly into the cast iron.
