Restoring a Starrett 12" ruler 

Thank you for posting this as i have just done exactly the same to two folding steel rules that were that bad (rusted up) i struggled to open them. I didn't have 20% acidity vinegar so using ordinary vinegar i left them soaking for 3 hours and now after using 1000 wet and dry i can see all of the markings Thanks again 👍.

I had no idea reapplying the black lines was this easy! I have woodworking squares I'm restoring... thank you for this tutorial!

That came out almost like from the factory, very nice. Thanks for the video.

This video has just inspired me dig out my old rulers that are in need of some restoration. They were made solid in the old days. Thank you and take care.

Just don't actually use this rule for anything. It's a shrink rule, used to make foundry patterns. Patterns are oversized to make up for cast metals shrinking as they cool. This ruler is 3/16ths of an inch longer per foot of length, so it might be a bit frustrating to use.

So cool........Love to see older good tools brought back

Just bought an old steel 2' engineers rule that needs some TLC thanks for showing us ,that's a nice job . Ant from Wales UK

Thanks for this. I inherited a small 6 inch Starrett ruler from my grandfather and have been wanting to clean it up some. Yours looks great now, I'll give your methods a try.

So many videos on you tube are showing how to basically ruin old stainless steal rulers, thank you for sharing this method, In my opinion this is one of the best ways to restore old stainless rulers... Thanks

My 3 adjustable rusty squares thank you for this video and their new lease on life. 😊 My speed squares will get the same treatment because they’re bare metal with no paint in their groves. 👍

THANK YOU so very much! This is EXACTLY what I was looking for. Well done, Sir!

This is exactly the video I was looking for! I have this vintage Globemaster 5955 Calipers I bought at an antique store. It was rusted to hell, I saw it and it took me a while to even realize what it was. Now I've restored it to working order, and it looks amazing! But the numbers are bare and hard to read, I've been trying to fill them for a week! I'll have to try this out!

Thank you - I just inherited about 50 similar various rulers from my father. Looking forward to restoring them :)

This is the way to restore a scale and to create a video of the process - Thank you!

restoring an old Vernier height gauge, very useful thanks

Great video thank you

Wonderful video. Thank you!

Not only a very clear and concise tutorial but the music was a great addition-not obtrusive at all. 10/10 video!!!

wow man....nice job....

Yoav, great job on the restoration, and a great video.

Awesome! I recently got my hands on a ww2 rcaf starrett. I plan and trying this

Clear instructions and very useful. Thank you!

Cool. A No. 375, shrinking rule, 3/16 per foot for thin brass. 👍

Beautiful work..nice...

What kind of wax did you use in the end?

Thank you, I just ruined mine using a permanent marker then I used alcohol to remove it but the lines came off

YOUR BACKGROUND MUSIC IS TOO LOUD ,DROWNING YOUR VOICE...

Music annoying and adds nothing
