A use for discarded (rusty) rulers

[Philip Davies]

This is the sole of a Stanley Bailey 4 1/2 and it is convex and probably has been since it was bought new.
How convex, I did not measure, but it was useless. Not wishing to waste the 50p it cost me, I decided to rectify the defect.
Remembering I had two rules, which had been in the stockpile for years (they were salvaged) and, being rusty, even if cleaned, the markings would no longer be visible, I thought to use them, just to scrape at the marking fluid, before using the engineer’s scraper.
Now the plane is useable, but before posting the picture of it, let me tell you that it is not an example of precision scraping, which I can’t do. In fact parts of the plane are now concave, which is approved by those in the know, perhaps to reduce friction? I don’t know.
