Snapping Spring-Stock (for scratchers, scrapers, blades) - C. in Indy - 07-31-2018
I was trying to find a prior thread on a survey of methods for cutting hardened spring-stock plates. I couldn't find it tonight. But I know at least one person talked about scribing the plate (with Exacto knife). Then, just recently, at www.donsbarn.com, he did a cut by scribing with a graver tool. That seemed worth trying!
I was considering buying a HSS graver, but then I decided to just grind a flat onto the end of a small triangular file. This works!
My first graver-line, just next to (to the right of) the blue tape:

My first snapped-to-the-line plate separation (well, I didn't grave the left end of the line deep enough....):

That sounds like a good way to get rid of some saws. Could we get a closer look at the business end of the file you ground, please?

Here is a stock web picture which shows about what I was doing. I used a triangular file for a 60-degree "V" cross section, but a square file would work as well. I tried to pick the sharpest vertex of the file, and grind the end of the file just a little off square to get a decent working angle on the sharp face.

This depiction was about the angle of attack I used, and as such there was very little chatter.
Thanks,
