Dipping hot roll steel in acid does a good job to remove mill scale. Can be as weak as vinegar. Don't let it sit for too long or it starts to rust. I would probably rinse with distilled water after and quickly air/heat dry it after.
As a woodworker, I periodically reflect on how easily one can produce a straight edge with extraordinary precision using nothing more than a plane and feeler gauge. Simply clamp two boards together and plane their edges as straight as your plane can manange. Then unclamp the boards and put those two edges together, and check the gap between them with the feeler gauge. The gap between them is double the deviation from straight of each board. So with a .001” feeler gauge, one can easily produce a straight edge that is less than .0005” out of straight over its entire length, which is damn good for basic hand tools.
When I was cabinetmaking at my last job, the precision we could get when joining 2 bits of laminate together using nothing but a block plane always satisfied me
It's all in your level of personal pride. Give me a wood or iron hand plane and I can clean rough lumber up. Give me a four side planer and I will clean it up and make it square and parallel. I might even make it straight. Add a molding or too at the same time and all at high speed. But timber is both forgiving and volatile. Plane it today and tomorrow it's moved. Tension or moisture gain or loss.
@@somebodyelse6673 They do become straight, because they are planed when clamped together side by side, and so they match - and then you flip one and compare it against the other, by laying them on top of each other. If they are not straight, they no longer match and you go back to planing. This works because a horizontal line is the only curve that matches itself when flipped vertically.
Ah, the good old 3 surface method... I expected nothing less... Also, nice seeing Alex mentioned... I hold a small state of him right next to the small statues of Stefan and Robin on my pedestal of machining excellence, supreme pedantry and dedication to precision... Also, are you mad boy? You shoulda drilled some extra say 10mm holes, and you should have put extended wooden handles, something akin to a mushroom shape, to give yourself a place to grip the instrument, which will somewhat insulate the instruments from your body heat... Wood aint the best choice, but it`s cheap, and can be replaced easily for solid cored silicone overmolded handles... When you seek precision, just breathing in a room without hvac to keep it lab grade atmo. cond. is enough to induce errors... Unless the room`s floor is the top of a thick reinforced concrete foundation, just standing near a machine or a surface plate can be enough to induce errors, let alone walking or moving about... There is a reason why true precision is expensive... It`s not all that hard to achieve, but to achieve it with ease, you have to have a remarkably controlled and rigid environment which allows the most minute oscillations to be stifled, allowing you to just have to deal with normal attentive procedures, like not handling instruments without an insulation layer as to not affect the instruments or a workpiece... Otherwise, a very nice project and a good undertaking in general! All the best! Steuss
i take pride on not running away from tasks that most people would consider tedious and repetitive to achieve a good result, but you sir, are beyond insane even for my standars
Sooooo after watching this awesome video and a few other less cinematically produced ones, I built 3 300x300x30mm reference surface plates out of welding 3mm mild steel sheet for the main plane and sides, 8mm thick flat bar for back reinforcement and rebar for concrete and gravel to stick to and make the thing more solid. Each plate weighs just over 9kg and I dont really have a proper way of meassuring how accurate they are but I cant fit my thinnest feeler gauge (0.03mm) under a small straight edge. But what I really found surprising was how I got them to momentarily levitate when you drop one facing another and then, when you try lifting the one above, it really, and I mean, really sticks to the one under, so you can lift both grabing the upper one even when the surfaces are completely free of oil. I looked up why this happens and there is a thing called wringability, but for it to happen, we would be talking about submicron accuracy so my guess is in my case its all about vacuum effect. Anyways, I came back to the video to say thanks and if anyone has any idea about this, feel free to leave your input, I'd apreciate it :)
Great job sir! I love seeing people taking on things like this with simple diy methods. One step I would have added would be a stress-relieving bake after welding.
Great project, great job! Those will serve you well and be more stable as they age. I made a 30 inch surface plate and lapped it to .002 and used it to make a small straight edge. I used the long side of a large (24 inch) framing square with no holes or weldments. I lapped the edges to .001 or better and parallel within .0002". It's all I need for um, woodworking.

I'm watching all youtube machining allstars for over 10 years. I'd like to say that your videos are great and keep them coming. I'm feeling some this old tony vibes and it feels good.
I’ve just found your channel and absolutely love these videos. I’ve been a machinist for 10 years or so and you are doing a spectacular job. You’ve definitely got depth of knowledge and creativity. It’s nice to see someone introducing hobbyists to old school techniques like scraping. You should check out a series of small books called “The Tricks and Secrets of Old Time Machinists”, I think you’ll enjoy them. I appreciate your demonstration of welding and fabrication as that is something I cannot do. Thanks for the videos!
Impressive! For future mill scale removal, you can get the bulk gone by making a little trough from plastic and soaking the surface in vinegar, it will eat most of it if it sits overnight. Make sure it’s submerged
Since I watched a video about the topic of flat plates and how they are the basis for everything in engineering, I wanted to see something like this. And you did it. Magnificient!
I love the quote "The final step is to repeat untill you dont feel insecure about posting the results on the internet", Spoken like a true content creator
Its all about how tolerant you are to tolerance. I have equipment from the 50's that has better tolerances than i can get on newer machines (material and the way they made things to last really shows) Enjoyed the video :)
Bravo! I thoroughly enjoyed the intended content (making precision straight edges from scratch) and the self-deprecating humor of the perennial "I'm not an engineer" and speaking into random objects (a boring bar and a die-grinding burr is what I recognized) as if they were microphones.
Great job! I’ve done some MS weldmets in the past and scraped them. Building a big bonfire and leaving them in there until it’s dead cold makes a big difference, they come out with no ring and reasonably well stress relieved.
As a professional lapidary I found your video very interesting. Glad to hear you used diamond paste, an excellent move. Use it every day in my work. Am having similar issues getting optical flatness along joins in my current work, so you have given me some new insights, thankyou. My material is a mixture of metabasalt/quartz/calcite and native gold.
Suggestion from someone that work in the precision industry, u don't put the straight edge on the ends, but on the 2/9 on each side, doing so gravity will have no affect on straightness, and if u want to be extra precise u should have left the parts in a temp controlled place for kinda of a long time if u don't want to thermal treat them, so u will not have any stress relief after lapping. Its can happen that stress due to milling or welding will appear quite some times after, talking about weeks/months
I’m a third year mech engineering student, I had no idea about the three plate method. So cool. I’ve learned more online then from university, I would say the constant assignments and disruptions it’s caused has actually impeded my learning. Don’t ever consider going back shool it’s for children and people that need permission to feel accomplishment, just keep Engineering.
I'd say you have to be kidding, but I'm pretty sure you're not. I'm a high-school dropout and know about the three plate method. Never expected to see anyone use it. Technically he has a five-plate system, since he can use both sides of each straight-edge. He just can't use the opposite side of any straight edge. Without knowing the precise distortion from thermal expansion of the materials it's impossible to know how straight he can possibly make his instruments in day-to-day work, but it's sufficiently accurate that simple matters like body heat will distort them sufficiently it can be detected with simple tools.
I'm a MechEng graduate, Josiah Whitworth wasn't on the syllabus. There's a big difference between the kind of engineer that makes things and the kind that designs them.
This is why the actual workers get annoyed with the engineers. You are learning how to use a pencil, not how to make things. Best to remember that if you want the cooperation of the actual fab guys.
But, in British Columbia, work unto you who appropriate the esteemed title of "Engineer" deemed in law to be a "short form" for the title of "Professional Engineer", a title bequeathed unto one only after 5 years of successful university study to achieve the degree of "Bachelor of Applied Science", because, with all that study, one hardly has enough time to remedy the "Bachelor" part... this is followed by a minimum of two years of servitude to a Professional Engineer, and that person feeling beneficent enough to present your name to APE, as worthy of receiving said title... Without the "benefit" of this process, one who has persevered through said process may feel that one who calls themselves an "engineer" well and truly deserves to be smacked about the head and ears, legally, sufficiently to abstain from such egregious misuse of the title....that is, unless you're a software dweeb, who can call themselves "engineer" all they like, since everyone knows that any idea of "software" and "engineer" appearing together is clearly meant as an oxymoron.
@@ajfreeze215 also you have a lot of techbros who barely even know how to program, who mostly outsource their software dev, who call themselves engineers.
I use to be employed as a “hospital engineer” a genuine vocation endorsed by Engineers Australia (if I bothered to pay their fees), no education requirements what so ever. By the way I was an excellent hospital engineer (due to my trade background, better than those with only engineering degrees).
You need to square out the openings to maintain flatness after thermal expansion/contraction. Also, do your best to maintain material temperature while rubbing. Your idea for mechanizing it was fantastic. Add springs and bumpers and put a few unbalanced weights on the sides freely spinning and getting thrown about by the rubbing motion, and you should have enough random motion to not require any manual rubbing at all.
Is not a school what makes an engineer. Your engineering skillset is determined by what you do with your brain and hands. Of course right mindset and attitude coupled with a good formal education make for much better engineer than mindset alone, but mindset and attitude alone are much more relevant. I am a school engineer myself, and a successful one on my own field. For years I taught at university and I can tell you my classroom was more than half full of people who would get an engineering degree but never be an engineer. After moving to industry I still see the same pattern, many (holding degree) non engineers working as engineers.
If this RUclips endeavour does not work out for you, which I do not believe would be the case, I see your bright future in stand-up. This is a first class comedy material. I have a great time watching your videos.

i am amazed you are still alive. most don't live too long after talking about that animal which shall not be named. also, thank you. i think the mating call is as pleasing as you described.

Re: Millscale Leave the piece soaking in vinegar for a day (warmer the better)- the acid loosens the scale and it rinses off with a hosepipe. Fastest way to strip it is a wire brush disk in an angle grinder, which strips all scale/paint/rust ect while leaving the bare metal.
Unfortunately the 3 plate method refers to 3 "plates" & does not work on 3 edges because they can't be rotated 90 degrees to each other. I would also consider the beam support points - Airy or Bessel points that give minimum deflection. Support the bottom beam on these points when rubbing together. Normalising after finish machining has to be done before final hand finishing.
Nice work, I’ve been preparing to do something similar for my own cnc build, Robin Renzetti would be proud. Have you tried using optical flats? I have a few and they are very humbling if you wanted to further go down the precision rabbit hole.
very humbling... well said indeed... they, and the electric 1nm test indicators... Shit capable of running a sane person mad in less than 2 hours... Well, not counting the hours of work you put in in an attempt to produce a precise, flat surface...
Next time you rig an auto-sliding movement mechanism, try combining two or three pivot points running at different speeds. This will vary the stroke distance...🙂
great video, I made a straight edge this way, I just machined from solid instead of making a weldment, I also had it stress relieved somewhere in the process, but I did do the three equal pieces principle, yes, it was labor intensive!
30% vinegar works great for removing heat scale. I would recommend doing it before any machining. Submerge your part or wrap it in wet paper towels then wrap with plastic to keep the vinegar from evaporating. Depends how warm it is and thickness of heat scale but it should take a few hours to overnight. A little agitation helps. Follow up with a good water rinse and wipe with a moisture displacing oil.
Nice shorts! Zed over here is a back country guy's name! I love your pendant/handwheel!! It looks like something Zed would build, but seriously, it's awesome! Very very cool guide and process. Were you also aiming to get the two surfaces parallel?
That's one way to do it. The long term test will show if you were successful. I am always amazed by the ingenuity of youtubers. nice job young man. i would normalize that material by leaving it out side for a season or stress relieve it in a well... a home made oven...
Muriatic acid and some stainless steel scrubbing pads with appropriate PPE works wonders on mill scale. Picked some up from a local store and fully cleaned one side of a sheet of steel (4ft x 8ft or 120cm x 240cm) in about 30 minutes. It does produce a nasty gas so good ventilation in a shop or outside while standing up wind is a must.
To check true flatness and eliminate bowing caused by gravity, the straight-egde should be placed on two round pins at their flex points. That would be the total lenght multiplied by 0.211, then substract that from each end and marked. The same applies for gauge blocks longer than 4 inches as bowing causes errors in lenght. AlsoNotAnEngineer
Fun sorta related fact - the 3 most flat and straight pieces of land are the landing sites for Buran (the Soviet take on Shuttle). They are 4 miles long and even account for the curvature of the Earth, so the edges look like they’re slightly raised and seem slightly angled relative to the ground.
A few people have mentioned dipping the mild steel in vinegar, if you are impatient like me, or have more rusted steel, try hydrochloric acid, works a treat. Rinse thoroughly in water and dry quickly. It’s literally now raw steel and will start to rust very quickly.
If you were a Patron, you could've told me how silly this project was from the start.

you have done awsome mate they usually do flats over 3 machines and total temp control. be proud of your work
Is not a school what makes an engineer. Your engineering skillset is determined by what you do with your brain and hands. Of course right mindset and attitude coupled with a good formal education make for much better engineer than mindset alone, but mindset and attitude alone are much more relevant.
I am a school engineer myself, and a successful one on my own field. For years I taught at university and I can tell you my classroom was more than half full of people who would get an engineering degree but never be an engineer. After moving to industry I still see the same pattern, many (holding degree) non engineers working as engineers.
If this RUclips endeavour does not work out for you, which I do not believe would be the case, I see your bright future in stand-up.
This is a first class comedy material.
I have a great time watching your videos.
When you said Z properly, I knew you were one of the good ones
2:00 Boy that looks like an aggressive cut, I wonder if I'm too conserv.. "Luckily, I broke my last one"
8:37 LMAO
damn man. Keep up with such inventive montage
5 videos and 75100 subscribers! This guys doing something right!
This was informative and fun! You now have 75101 subscribers!
Hot damn. You should have asked. I’ve got some could have borrowed in marrickville.
My penance was due. But might be cool to check em! Fling me an email if you feel like it.
Where do I find your contact info
sitting here at 2am on a Monday morning drinking my 3rd shot of vodka, and watching youtube videos on how to get into machining. god bless you and your humor, sir.
Love this channel. You're funny and entertaining. I'm glad I found you.
i am amazed you are still alive. most don't live too long after talking about that animal which shall not be named.
also, thank you. i think the mating call is as pleasing as you described.
As a toolmaker, one up from a " engineer" boom yes I said it 🤭 the use of the mic for the ground made me sub 😂👍
I've heard this over and over, but I've never seen it done. THANK YOU for showing us!

Thanks for the educational and maybe more importantly entertaining content! You had my attention from the title to the end. Ground clamp clutch was brilliant.
Based on the title and subject I was expecting something a little more dry. Then you hit me with the “easy peasy lemon squeezy” 😂 SUBSCRIBED! Love this guy 😂😂😂
Your witty narration earned you a subscription. And, yeah, I am an engineer! 😊
0:10 That mic with a gold insert gives best voice clarity...
"This is my first attempt" is a scary line when it comes to a project like this.
Re: Millscale
Leave the piece soaking in vinegar for a day (warmer the better)- the acid loosens the scale and it rinses off with a hosepipe.
Fastest way to strip it is a wire brush disk in an angle grinder, which strips all scale/paint/rust ect while leaving the bare metal.
Unfortunately the 3 plate method refers to 3 "plates" & does not work on 3 edges because they can't be rotated 90 degrees to each other. I would also consider the beam support points - Airy or Bessel points that give minimum deflection. Support the bottom beam on these points when rubbing together. Normalising after finish machining has to be done before final hand finishing.
wronnnnng! I made a straight edge same way, go back and rethink this!
good on ya for havin a go, you have a lot more patience than i have. Good stuff keep it up.👍👍👍
It's pretty notable on how influential speed holes are, since their inception on the epic, Homer's chariot.
Well done.
Love your sense of humor
I'm glad I'm not alone. There's more of us out here the garage builders ...- making awesome
9:41 my boy being an absolute Chef
I love the fact he's using a tool holder, replete with carbide cutter for a microphone the whole time.
Nice work, I’ve been preparing to do something similar for my own cnc build, Robin Renzetti would be proud.
Have you tried using optical flats? I have a few and they are very humbling if you wanted to further go down the precision rabbit hole.
very humbling... well said indeed... they, and the electric 1nm test indicators... Shit capable of running a sane person mad in less than 2 hours... Well, not counting the hours of work you put in in an attempt to produce a precise, flat surface...
Hilarious the microphone! Very nice style of documenting your work!
At first I had my doubts but then you engaged the racheting micrometer and I was humbled. Carry on.

Next time you rig an auto-sliding movement mechanism, try combining two or three pivot points running at different speeds. This will vary the stroke distance...🙂
You remind me, ever show, why I subscribed. Thank you!
Not sure why I watched this but you’re entertaining 👌
I'll take it!
I have no clue what you're doing, but your delivery is delightful!
Praise the algo for directing me to this engineer's channel.
Wow .... that chain magig you invented to rub the 2 surfaces was genius!
great video, I made a straight edge this way, I just machined from solid instead of making a weldment, I also had it stress relieved somewhere in the process, but I did do the three equal pieces principle, yes, it was labor intensive!
11:44 - The surfaces were Boeing? ;)
great vid as always
The three plate method only works with square or round workpieces.
You need to be able to turn one of the planes 90° to the other.
just found your channel and I'm an immediate fan love the tot/ave style
I rally like you hand held mic with very sharp and durable sound quality.
I just found this channel, haven't sub'd to something this fast in my whole life
That is some really beautiful train track you made!
You're a better engineer than most that I know
9:50. Learning about this blew my mind.
Love the custom mic holder. As long as it will get the job done. Good work.
30% vinegar works great for removing heat scale. I would recommend doing it before any machining. Submerge your part or wrap it in wet paper towels then wrap with plastic to keep the vinegar from evaporating. Depends how warm it is and thickness of heat scale but it should take a few hours to overnight. A little agitation helps. Follow up with a good water rinse and wipe with a moisture displacing oil.
The wet paper towels is a good trick. I always use vinegar on smaller parts, but I haven't got any metre-long vessels
Any size container, within reason, can be made with dimensional lumber and plastic film. Just a thought.
Nice shorts! Zed over here is a back country guy's name! I love your pendant/handwheel!! It looks like something Zed would build, but seriously, it's awesome!
Very very cool guide and process. Were you also aiming to get the two surfaces parallel?
Thanks make! Not at this stage, but maybe in the future. Like once I've got a power scraper haha!
I really like the group clamp. The cheapest that i has seen 😅
Regards from Venezuela
Great video . This was the first video of yours i watched and certainly not the last. You had me at the precision clamp.😂
That's one way to do it. The long term test will show if you were successful. I am always amazed by the ingenuity of youtubers. nice job young man. i would normalize that material by leaving it out side for a season or stress relieve it in a well... a home made oven...
Got to 1:46 and now im subscribed... hope your happy now with your witty aussie wit.
5:03 oh now you tell me
Keep going man. The stuff is campy without getting schlocky about it. If u know what I mean. 😊
Muriatic acid and some stainless steel scrubbing pads with appropriate PPE works wonders on mill scale. Picked some up from a local store and fully cleaned one side of a sheet of steel (4ft x 8ft or 120cm x 240cm) in about 30 minutes. It does produce a nasty gas so good ventilation in a shop or outside while standing up wind is a must.
To check true flatness and eliminate bowing caused by gravity, the straight-egde should be placed on two round pins at their flex points. That would be the total lenght multiplied by 0.211, then substract that from each end and marked. The same applies for gauge blocks longer than 4 inches as bowing causes errors in lenght.

Fun sorta related fact - the 3 most flat and straight pieces of land are the landing sites for Buran (the Soviet take on Shuttle). They are 4 miles long and even account for the curvature of the Earth, so the edges look like they’re slightly raised and seem slightly angled relative to the ground.
A few people have mentioned dipping the mild steel in vinegar, if you are impatient like me, or have more rusted steel, try hydrochloric acid, works a treat. Rinse thoroughly in water and dry quickly. It’s literally now raw steel and will start to rust very quickly.
