I feel like they're related to Clickspring.

That's awesome! Let me know!

@@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!

I used to teach shop and math, and your videos were mandatory in my classes too!

I would love to watch Chris make this with modern machinery.

When I saw the thumbnail I assumed it was clickspring

@@Daxis834 Considering how he's going about the Antikythera Mechanism I think he would end up in some deep dive with authentic tools and another PhD....

Except Chris would make his own period tools and make it with them! It would be an awesome video.

right

Yes! yours is so beautifully made it really was an inspiration! I hope mine is nearly that nice! If you want get in touch with me (again) via my contact page and I can include your photos in the compilation video I hope to make

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.

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

@@JohnBare747 Hmmmmm, a knock off? Why not? :)

@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.

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.

This museum used to be a reference. It was an inspiring place to go . Now it’s just a mess .

With what? How are you going to make anything without proper tools? I want to see you make anything straight without something that is already straight.

You're welcome! Film your build! :D

I can send you the STLs. get in touch via my contact page (in video description)

Oh I can give you a .step file. Contact me

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

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).

Pretty rough, considering this was literally the first precision instrument of its type. How would a craftsman of any skill level manage to make it perfectly?

Maybe? Would other formats be useful, too?

@@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.

I used PhotoCatch on a M series Mac. It's so much easier than other programs I've used

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.

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

I read Ben's paper (published in a journal so I can't share it, sadly) that goes into detail on this which boils down to brass from 1776 or a century later is very similar. It means it could be that old, but certainly doesn't prove it.

@@machinethinking do you have the reference please?

@@johnsherborne3245 Ben's paper that includes the XRF analysis is in the Bulletin of the Scientific Instrument Society No 148 p 30-35

@@machinethinking many thanks, the role of XRF in archeology is very intriguing.

Simple machines. We learned about this in grade school. It's pretty simple

@sdrc92126 Yeah, it's simple now. Now it's been made to study. Adaptations and upgrades are simpler than conceiving designing and making first.

@@hahaha9076 It's all screws and gear ratios

I'm not sure how he did his measurements, but there is reference to him being thrilled when a cylinder was bored within the accuracy of a thickness of a coin.
