This is almost a blog post by proxy. John specifically asked me to put this little tip for marking up a stainless steel sheet before cutting it on a guillotine.
If you use a piece of copper when marking your stainless steel sheet, you’ll find that it doesn’t scratch the stainless underneath the protective plastic coating. Essentially it allows you to cut the plastic and mark your cutting line.
You can use anything from a two pence piece to a strip of copper that you’ve cut to a specific width.
Here’s one John made earlier:
I know it doesn’t look anything special, but you can just run it down the side of the sheet to get a perfectly straight line in a couple of seconds.

Well you’d have to run the marker along a straight edge, which you don’t have to do with the piece of copper shown in the pic. Maybe I shouldn’t have mentioned the 2p, but if you’re wanting to cut small strips off a sheet, then this is an infinitely quicker way to do it.
Apologies if I didn’t make it clear.

I’m not sure I grasp this tip completely. Is the idea to scuff/cut the plastic coating with copper (which is soft)? If any random piece of copper will do, what’s the part about cutting it to a specific width? And if there’s plastic on top, why not just use a marker?
Of course, I’d rather be cutting metal with a CNC plasma table anyways…
