So using a surface plate I can reliably, altho not fast, get to one tenth (or maybe better- I’ll just say a tenth given limitations of my equipment and environment) flat parallel and square/foot on projects that are less than 30” long and 12” wide. With parts that I cannot rub directly on a surface plate I’m at 2 tenths/foot and occasional false starts. Tips? Techniques? Yes, I know about maintaining constant temp, avoiding sun etc. Just wondering how guys rescrape jig borers and similar parts that can’t get to a surface plate.
