This is the best video on scrapping I've seen. I'd love to have subtitles as I feel I might be missing some subtle explanation. Thanks for sharing this.

Good video but almost blew my brains out till I turned the sound off hah!

[@helenodetroyo7035]

WOW I LOVE THAT MUSIC! 🤣 THE BEST MUSIC EVER! 😱

[@barryhughes9764]

To scrape a flat surface from scratch you need to have three pieces. They are scraped against each other in rotation thus eliminating any concavity or convexity. You will only scrape a flat surface by this method to an accuracy equal to or less than the master plate you are using. The old ways still remain.

[@093tatsu7]

absolutely right!

[@atz123ify]

This music, like all things, is meant to be enjoyed in moderation and in the proper setting..... Unfortunately this is potent stuff and is too much for many people to take either at high volume or for extended periods of time. Mario successfully incorporates this type of sound into the video game at low volumes and it serves as background noise while navigating the various levels but the low volume blends with other sound effects in game play to break up the repetitious music. This is a balanced application for such music, here, the video content being precision scraping to achieve a flat surface" your viewers are likely of a certain demographic of machinist and fine craftsmen and women who would scoff at such obnoxious music being used in an otherwise good video. I suspect that 093 tatsu has deliberately used this track and adjusted the volume intentionally to patronize the viewer and because the content is solid he can care less about the music so he either adds no music or adds music that will stand out and be so unfit for the application that common critics will state the obvious and comment on the music. If i understand the sense of humor and personality of the individual (such as myself) who sees only the brilliance and comedic relief that intentionally ruining a video with such horrible noise as this presents then i have done my service by posting this comment, if not, it was just a thought and is meant to justify the videos music rather than condemn it. Without the creator's direct statement as to why the music was chosen, anything said regarding the music is either opinion or speculation. In my opinion it's great and i speculate the creator hasn't ruined his video by accident but by design.

Dear Sir, can You plese share what kind and brand of marking paint You are using to highlight the high spots Thanks in advance!

[@093tatsu7]

I am using traditional Lead Oxide. TRUSCO in Japan. It is not good for occupational safety but still many brands are available. I am looking for good alternatives.

[@StamD65]

@@093tatsu7 Seems, that many Japanese crafsmen are using this type of marking medium. In Europe, we use either water based stuff, or classical Prussian blue oil based paint. The oil based paints are not easy to clean, and the water based stuff promotes corrosion on metal surfaces. No ideal variant.

[@spidersinspace]

I would be interested to know where you got your sound track. It is so good I can't get it out of my head.

[@milantrcka121]

Good stuff but the godawful noise!!! Knock it off!

[@edstimator1]

test your intelligence people! Find the mute button?

[@swillswill]

All very well and nice, but the flatness is measured against a reference surface, i.e. the granite. How was the granite made to be flat? How do you create the initial flat surface against which to measure?

[@zubirhusein]

+swillswill It's known as a machinist's table, you purchase it

[@jiriskala]

+swillswill I think it is possible to make a flat surface when you have three pieces. You compare them with each other, scrape, and repeat. It should converge to a flat surface on all of them.

[@lookoutforchris]

+swillswill Uh, the "granite" is a surface plate. It's sold as a reference surface for inspection and machining. A high quality surface plate will be flat to within ±0.000025".

[@jasonbucy]

I know its been 2 years but.... 0.000025" is 635 nanometers. there is NO WAY that's true. That's smaller then some wavelengths of colors...

[@NickC84]

Check out Federal Specification GGG-P-463c, It sets the Metrology standards for surface plates. For an 18 x 18 or smaller surface plate it can't be anything over .000050" out in flatness or it's rejected. A modern, good quality, granite surface plate usually beats that. You're correct that it's smaller than some optical wavelengths, they use inferometers to check the flatness. It's crazy, but it's true.

[@fourthz4460]

[@smo3241]

It is interesting how were made spindles of the first machine tools in the world? Is it possible to get a cylindrical part using this method?

[@093tatsu7]

It is possible for hand scraping to make spindles by employing tapered shaft/sleeve bearings.

[@smo3241]

@@093tatsu7 Can you explain more in detail what do you mean by employing tapered shaft/sleeve bearings?

[@TJ-ed8xg]

hello, Can you tell us what "bluing"/marking substance do you use ? Occident rather use prussian blue to do that. And it seems (from youtube videos) that Asian people prefer this orange solution. ? Thanks a lot

[@093tatsu7]

+ty dji This orange substance is red lead (minium). If you use it, please take care of your health.

[@TJ-ed8xg]

+093 tatsu Thanks you very much for your answer ! Why don't you use prussian blue instead ? Or for exemple iron oxyde ? Your pigments are mixe with some oil don't you ?

[@woozhi9218]

@@TJ-ed8xg i used ink pad filler and a tiny but of grease mixed to it to make it non drying and thicker .

[@oldgitsknowstuff]

Yeah yeah ! Everybody's an expert. Scraper this, scraper that, burrs this & that. What about the grinding? Dunno, don't care, its the finished article that counts. A perfect (within human parameters) is impossible to achieve, it is NEVER completely flat (one of life's little setbacks) however, a 'Gas tight' fit could be classed as a perfect surface and this is why Surface plates, Vee blocks and other measuring devices cost so much. I cannot read Japanese, if that is the subtitles language but the airtight seal on the final product speaks volumes. Try taking in the method.

[@marshalcraft]

um airtight seal has no relation to flatness. you ever hear of metal crush gaskets, they deform to the surface and get air tight seals, used for high pressure high temp stuff, clearly the crush gasket is about as far from flat as you can get.

[@mackk123]

The endwringing is the proof in the pudding

[@alihaggis78]

It seems counter intuitive that an extremely flat surface could have so many scrape marks in it. You'd expect it to be a mirror finish.

[@krap101]

there's a difference between flatness and surface finish

[@wolfy9005]

You could polish it with some 3-4-5-6-7000 grit lapping compound on a piece of glass if you want?

[@tonyennis3008]

You're screwed if the glass isn't flat. Machinists have different expectations with respect to flatness.

[@robinhodson9890]

In that it can be smooth and curved, for instance, yes. But that still doesn't answer why scraping is best, if it is. All the attempts at explanations say "it just is", which isn't what explanation means. It calibrates against a standard flat surface, so how was that flat surface produced in the first place?

[@tkkcustomknives]

If you want to know how to make a surface plate without having one already you use the 3 plate method (you can look it up on goole), this was invented by Sir Joseph Withworth. Scraping is often superior to surface grinding because first of all you are not limited by the size of the surface grinder you have (you can take a scraper to a machine) Secondly a scraped surface makes a better bearing surface than a ground surface (ground surfaces tend to push all the way oil out en stick together, thus making the machine wear out quiker) this is why scraping is used primarely on machine ways that have to slide accurately. And at last you can scrape very accurately (the only limiting factors are the skill of the scraper hand and the flatness of the surface plate, and the surface plate like i said earlier can be made to any flatness wanted by repeating the 3 plate method) while a surface grinder can never make a part more accurate than itself, also with scraping you don't have any heat build up or clamping force that can distort a part.

[@1-shotslinger108]

Was that a Chinese Budweiser can in the end there ?

[@093tatsu7]

That is oil spray can.

[@Ke3per88]

Thought for a moment you were coating the surface plate in grinding paste, haha

[@ajragan9805]

093 tats where did you get your hand scraper? Thank you

[@ef2b]

Would this work on hardened steel, like O1? Would an improvised scraper, like a ground file, still work? Thank you for the video.

[@fearlyenrage]

no the "to scrape steel" has to be soft. When you try to scrape on harden steel the carbid tip will run over the surface. You can scrape alu steel and cast iron, brass works to. But harden steel is to grind. Why are you asking?

[@ef2b]

@@fearlyenrage I'm a woodworker. Hand plane blades need to have their backs lapped flat, which I do by hand. Occasionally, I will encounter one with a hump. In addition to this being a bunch of material to work off, I think there is a tendency for the work to teeter-totter on the hump so that lapping doesn't focus on the high spot. I was wondering if I could scrape down the hump. These blades are typically hardened O1. What I have done in the past when a blade was particularly bad was to use a handheld grinding wheel to try to focus on the hump, but at least in my hands, this is crude. That's the background.

[@fearlyenrage]

@@ef2b aha. Ok well it is possible to apply water to a running, best works on a slow running, beltsander. But a warning here that works safe as long as no water enters the motor housing! Why add water to a beltsander? To cool down the grind so the steel wont heat up. I dont know how hard your steel is maybe it is a chrommoly then it is very unlikey to scrape it. But when it is a japanese sanmai steel sandwich then the softer steel could be scraped. When you would film the blade steel and show us the plane maybe we could come up with an idea.

[@rodolfomaduro8157]

What is the brand of your file? All japanese machinist videos that I see, the files are much better than mine.

The color paste should be evenly distributed on the surface plate. Otherwise your reading is false.

[@peterwass8467]

if you are going to do a lot of scraping, get a power scraper.

[@Letusbeguided]

Lol a lapped surface is no good for parts that need to move against each other. Thats why scraping is used as it DOES leave peaks and valleys. It is extremely flat over a number of points in a square inch.
