Marking out metal

- One of the first things you need to be able to do when working with metal is marking it out correctly. This video shows how to use a scriber, engineers square, rule and centre punch to mark out a piece of stainless steel that is coloured using engineers marking out fluid, which is often called engineers blue. Brought to you by www.ultimatehan...
This video takes me back to the days of "hand fitting" at the BSC training centre. I remember if you dropped an engineering square,then it had to be sent off to be re-calibrated. Thanks for the video, it was very comprehensive. Cheers. N.

Great video. I can recommend using an optical center punch for the utmost accuracy on smaller parts such as the piece you worked on in this video since it is easy to drift half a millimeter or so from the intersection of the lines. This method is good enough on larger fabrication projects.
Thanks for the info! 👍
Really enjoy your vids mate, very useful. I was taught to use the rule the other way round, the same as a combination square. As in align the relevant measurement mark on the rule with the scribe line then scribe across the end of the rule. Thanks again.
Thanks for the comment 👍
Clear, concise and very useful. Thanks for taking the time and trouble to post the video.
You are welcome.
Thanks for the comment ;-)
I’ve got my technology gcse tomorrow and this video helped me out a lot, thanks!
Best of luck with the test ;-)
Thanks for the comment 👍
Can you help me on how to read a working plan for turner plz❤️👌
hell even here in the U.S. i use metric. its just easier and more accurate especially when doing tiny little things. if im doing something big whatever i might use inches or feet. but for a little project such as the size of this piece of metal, metric all the way.
I also use both- just like you, for exactly the same reasons you do.
Thanks for the comment
living in the US... i detest tmmost of the imperial system.
when i design for 3d print i always use metric. i love it
Imperial is so damn difficult to use, at work we have metric and imperial drill bits and I can pick up a 12.1mm drill bit and know immediately that its 0.1mm larger than a 12mm drill bit. With imperial drill bits I have to get out the Vernier gauge ;-)
Thanks for the comment
Which medium for use ? That means colour
What item should never be used to mark metal surfaces? I would appreciate the help
I'd never use anything that leaves a thick line, like a bullet tip marker etc. A thick line can mean that when cutting etc. your cuts can be the thickness of the line out. etc.
Thanks for the comment 👍
Definitely a helpful video.
Thanks for the comment
Marking blue for layout, engineers blue is for fitting components. Great video though, covers things very well.
Thanks for the comment ;-)
by fitting components do you mean coating them with blue and putting together then taking apart the parts to see where the blue is worn off to find high spots, etc?
That's correct. You can use sharpie/marking blue for this but it doesn't work as well.
Correct. Thought personally for marking I prefer a sharpie type pen, much cheaper and easier, less messy too.
What about human error?
What is the recommended hand drill to use?
Cordless ones have a lot of chuck wobble which causes thinner bits to snap off quite easily!
Thanks 🎉🎉😊
How do you get the blue off the metal?
You can wipe it off using methylated spirits (denatured alcohol) and a clean rag 👍
What's the tip of the scriber made of? carbide or something hard to scratch the metal?
Yes, they are normally made of Tugsten carbide. You can buy replacement tips for the one I use.
Thanks for the comment
This was great, thanks for posting. Cheers

You are welcome.
Thanks for the comment ;-)
I like to mark with little sort of V's and I always start marking from 10mm on my rule, just personal preference
Thanks for the comment 👍
Good idea thanks for sharing..... Nice gloves
You are welcome
Thanks for the comment
Great video. Very informative. Thanks :)

Thanks for the comment
is that a dewalt bit i see ?
No, that's just a regular HSS drill bit.
The Dewalt pilot drill bits have arrived though, I'll have a go with them when I get chance ;-)

Which engineers blue do you prefer? The spray type or the type you have to dab on.
I have only used the one which you dab on.
