You would need to have the aluminum castings milled, but the steel ways could be ground. Saying that, you will be missing some if not most of the ability to correct defects and make adjustments as you complete the build. Gingery suggested fitting things together as he laid them out in the book so that casting #1 would work with casting #2, etc. Much of the scraping seems a horrible task but if you look at it as steps then first you should remove the worst of the material with a file then use sanding to get closer then a final finish with the scraper after the castings are as flat as you can make them. Scraping shouldn't be as tedious as everyone seems to make it.
Are you having a bad experience with scraping or are you reading trouble others have had and want to avoid trying? Try something small and take a few photos and maybe we can suggest ways to make it easier?
