@@machinethinking Aerospace engineer here and I absolutely agree on this sentiment. My goal in life was a moon base as was many of my classmates back in the late 80s. We truly believed we'd build Space Station Freedom and then go back to the Moon. Then 1 morning Challenger happened. Irrespective I haven't given up the hope we'll get there and a couple of you videos have brought real clarity to what we'll need to do to build a moon base. Its a simple matter that we can't simply fly everything we'll need to the Moon. Its the simple cost. By various estimates its between 1,000 and 1,000,000 times more expensive to put 1kg on the Moon than it is in Low Earth Orbit (LEO). I do industrial control systems and I can tell you that copper is heavy so wiring up a Moon Base like its the Rebel Alliance snow base in the Empire Strikes back or any other Sci-fi movie is JUST NOT GOIGN TO WORK unless you can get the Copper locally. The same goes for all the other stuff we'd need. But we will need to make things that go together with parts made on the Earth. So one of the most important items that MUST GO to the Moon is a set of Johansson Gauge Blocks. I would NEVER have known that without your video. There's a pile of stuff I have learnt form your videos and unfortunately due to circumstances I can't do a lot more right now than thank you and offer my encouragement to keep doing what you do.

I passed along the information on this channel to the machine shop teacher at our local high school, I’m occasionally in contact with him as the CNC mill for our robotics team resides in his shop / classroom. I’ll see if he thinks this is a project that any of the seniors can take on, it’d be an awesome project to work on. Thanks very much for this latest episode!

"The nice thing about it... Is the Watt ifs." I see what you did there, Mr. Science History Man.

[@Dr_Do-Little]

I've seen images and videos about this micrometer before but never close up of parts like you see at 2:36. The "badly made parts". I'm still in awe for the object but funny that now I can think: "I could had made better parts in my first months of machining school!" Of course I wasn't born in the 1700's. That's a huge difference.

[@andersjjensen]

Good to hear you're back! Machine Thinking and New Mind are my two favourite YT channels, and both of you are "low volume"... because quality takes time...

[@aserta]

Whomever made this, understood the one thing, that's key to micrometers (because essentially this is a modern micrometer, cut into bits) - precision. The anvil could be replaced by a sleeve type and then the graduations naturally will be used on the sleeve rather than bother with the cumbersome worm. Regardless of quality, the person understood tolerances and backlash. Given the quality of the work, but more importantly the quality of the parts... i'm wondering if this isn't an apprentice piece. We have this in art, why not in a machine shop. Be it copy of "an" original or a stray though made with scraps from other work... it's old and therefore interesting.

[@JohnBare747]

Perhaps a prototype made from scrap bin pieces as there for sure are reused stock, who knows? Fun to conjecture, and for sure food for thought.

[@bosanaz2010]

probably.Every machinest will tell you working with out CNC takes time.And if you need something fast or if its just a proof of concept you dont start chamfering every corner,rounding stuff of on the mill.Doing stuff precise ,where there is no need,too What is strange is worm gear.Its so warped its strange.Curios if its heat threatet maybe? Also watt was maybe just a poor machinest in the end? I mean not everybody feels the file as a extension of his arm.... I think i will remake it with my modern workshop,when my konventionel mill is free@@JohnBare747

[@carlthor91]

@aserta I think the reason for the attached andvil is that the maker, could not zero on the andvil any other way, as the measurements have to be up to today's standards to come close.

[@fxm5715]

In some trades it's traditional for people to make their own set of tools of the trade during their apprenticeship/education, particularly in the machinist world. It is the shop that can build itself, after all. A number of my professors in college still had the tools they had made for themselves at the start of their careers.

HE'S BACK

[@KipIngram]

I like to look back at how the developments in physics "fed" the progress of technology. It's of course a very complex interplay, but I think we can generalize it to some degree. I do it like this, at the highest level: 1) Mechanics (Newton's laws, F=ma, etc.) 2) Geometric optics 3) Thermodynamics 4) Chemistry 5) Electromagnetism (optics improved) 6) Quantum theory (nuclear processes, chemistry improved, optics improved)

[@Dinnye01]

This one was worth the wait.

[@brianpeers]

Ben who is a man of detail searched his wardrobe and brought out the same tie from the original interview. Well done. A sense of humour I’m guessing. I like his style.

[@guytech7310]

Just because its crudely made does not mean it wasn't from Watts. Very possible it was a prototype using bits of scrap material to prove the concept. Likely the second made version was much better constructed, and because it was better made it didn't get put on a shelf or box for safe keeping because it was used daily. Lots of people make crude prototypes before making a much better version.

[@motjuste8549]

What a great set of plans! Now I really need a machine shop just to make one of my own.

[@mikeyjohnson5888]

On the topic of build quality. TBH, it being nearly the first of its kind, I can see it being a test platform for what works and what doesn't. Machining was far more labor and time intensive than these days. It needs to be understood that while it wasn't perfect I'm sure it blew any metrological equipment of the day out of the water. Even in its crude state, I'm sure it was a boon to people that could appreciate it. People need to understand that most things we take for granted had pretty humble beginnings.

[@Distortion0]

So glad you're back! I missed your videos

[@BubbleOnPlumb]

It seems like it might have been a prototype built as a "proof of concept" for the device. When you are not entirely sure that your concept as a whole will be appropriate for the purpose, a maker will often coble together a preliminary version just to verify that its going to function as intended and be suitably suitably accurate. Going through this exercise typically identifies changes and modifications you will want to incorporate into the next generation of the device. Once you are satisfied with your design, you can then take the time and trouble to "perfect" your finished version for the utmost level of performance you are hoping to achieve.

[@ZetaPyro]

8:40 Is that the first face reveal on this channel? Great work! Looking forward to completion of your micrometer!

[@dmeemd7787]

New video!! Awesome!! 🤩

[@Antuan2911]

Your videos are so amazing, you give to us so many knowledge. Thank you! Regarding the poor condition of the micrometer and the consequent lack of accuracy that this implies, I would like to say some thoughts. At that time, when the standards had not yet been fixed, maybe they didn't mind if making for example, a shaft with a diameter of d, it ended up being d+0.05 due to micrometer error. Of greater importance to them was probably whether they wanted to make other shafts with the same diameter or to make a hole that this shaft would pass through, measuring with the same micrometer so that they also came out the same, i.e. repeatability. That is, if the construction was completed and the customer took it and worked, then their dimensions and accuracy no longer mattered because a part would never be taken from one machine to put it in another. Everything was custom.

[@chrisdsouza8685]

Where have you been? I have been checking daily for your video for at least 4 months 😍

[@fridgeffs5662]

When you think about it a micrometer isn't that amazing. You just scale up orders of magnitude to view something small in a number you can measure. But it really was one of the most important things ever made. To allow for the new precision of machinery opened a lot of doors

I'm so happy to see yoy came back to this. I really can't believe Watt made this. The quality of his engines, and there is this crudly made device, that by its design is ment to be precise. I don't believe he made something so poorly.

[@Noone-jn3jp]

I understand the assignment. It’s time to make Ben proud!

[@RegebroRepairs]

Do we have documentation of Whitworth's prototypes? This one looks more like Gascoines that Whitworth's, so I don't think it's inspired by Whitworth, but it could be him just throwing something together trying to build Gascoines micrometer, and as a result coming up with a lot of ideas on how to make it better. But maybe we know this isn't the case? I'm just throwing ideas out there. :-D

[@CalebWalker-lp3rz]

what photogrammetry software did you use?

[@robertdascoli949]

Yeah, I know. Everyone talking about the micrometer, but that software is almost magic.

[@machinethinking]

I've used a couple different ones, but the one that's the most magic is PhotoCatch. It runs very quickly on M series Macs (I had one for work) and has almost no options (unlike the others which have a dizzying array) but produces beautiful meshes straight away. Seriously blown away. My go-to on PCs is 3DF Zephyr, but that's mostly because I have an old perpetual license. It takes a lot more fiddling to get results like this (especially the thin feature of the back dial).

Watt, was he thinking when he tore his machine heart apart? From what we all here would have had let suffice, his mind was already very well Eulered and so augering now sure feels nice.

[@markcahoon2534]

A lot of the inventions were already invented before one of the many resets, a lot of these inventers just copied these things and claimed it as their own. I am not saying this is one of those cases, but as you say, there is something off about it. The Antikythera mechanism was one of those inventions made before one of the resets, that's why no working one was ever found. It is also why the tech that was used to make Pyramids can't be found, or worked out, with what they claim was the technology in use at that time. If you don't think resets ever happened, we are in the beginnings of the next one, 2030 is their goal. It is why we are close to WWIII, it's been planned. The world is their stage.

[@larryscott3982]

As for its crude appearance, could it be an experimental prototype? A proof of concept model? Looking forward to seeing modern machining make one. I suppose a true ‘replica’ would have to be crudely made. But a faithful rendition that represents the design and truly a functional micrometer would an homage to Watt - assuming it’s his design. The question is whether the design is a micrometer, theoretically. Or is it part of some other machine. I assumed that question has been answered.

[@johndennis3181]

Cool simple design, I think keeping the spindle tight to the gib would be a challenge without binding the lead screw. Other that that is looks like it would work well. How parallel is the anvil face to the spindle face?

[@ocratitude]

Love your content. Please keep up the hard work!

[@appa609]

The real question is how did anyone make a decent micrometer without access to other precision tools? It's relatively eady on a modern lathe because the lathe is, effectively, a better micrometer. How do you cut a thread to a better tolerance than the tool used to make it?

@@machinethinking I think for people with a 3D printer or access to CNC machines .dwg and .dxf would be very useful. I retired a couple of years ago, so I am only familiar with AutoCad 2012, but I used a copy of AutoCad 2019 last night and found I could convert the .pdf to dwg after separating pages in Acrobat DC. But will not be as good as the original 3D model space files, that your CAD modeler produced. I should imagine your Micrometer could be made in a few hours on a serious CNC Machine and maybe one of your younger viewers might be able to get this passed at college, as a project if they are doing a CNC machine course.

Having hand made numbers of tools , I may change the ideas I have a dozen times , to get the final tool . In this case the screw and the nut are the important parts . They had only the crudest of tools to make their device . Their question to self ? it is not parallel . Does it have to be parallel to work . It will take X # of hours to remake the body of the tool . Will it make a significant change in the tool ? If not use it . Then make the next one more accurate .

Thanks for uploading the plans, I'm adding them to cad but I'm confused why there isn't 50 divisions, with it being 20tpi screw fed then 1" ÷ 20tpi is 0.05" anvil travel, divide that by 49divs is .00502" , close enough but if it had 50 divs it would be an actual 0.005"

[@machinethinking]

The original is not decimal. I think the divisions on the original might come out to 1/1700” but I’d have to check my notes. The real screw might be closer to 19tpi.

[@markhobster8113]

Thanks, it makes sense in a way that something so old might not use a standardised thread which isn't a fastening, myself having thought about it I'm designing to me a metric 10mm diameter 1.0mm pitch screw, and a 25T 0.5mod worm wheel, both dials having 50 main and 50 minor divisions so it would record 0.01mm. I may just be daft and have rhe large dial as 100 main and 100 minor :) , to then have down to 0.005mm The 25T gear with a 50 div small dial would then read 0.5mm increments
