In this thread I'll be posting the results of tests I'll be conducting on my Brown & Sharpe 72" Camel-back Straight Edge.
This discussion started here: https://www.practicalmachinist.com/vb/machine-reconditioning-scraping-and-inspection/large-straight-edge-questions-354079/
First off, I want to state that the goal of these tests is to:
1. Accurately determine how flat the straight edge is before and after it is re-scraped, using an appropriately sized surface plate.
and 2. Compare these findings to other methods of determining flatness that don't involve a large enough surface plate.
I'm not doing this as a way to cut corners, but rather to see how these other methods actually stack-up and why. I want to better understand how these large straight edges sit and flex so that I can handle and use them well enough to take full advantage of their size.
