Totally transfixed on the video. Man this has got to be the best video i've seen all month! Beautiful machine, masterfully manufactured, excellent explanation of the workings. This is what true craftmanship is all about! Thank you so much for uploading!

Truly a testimony to what mankind can achieve when focused on high levels of order. You have made an amazing machine, which is certainly a reflection of your character, sir, refined, humble, talented, skillful, courageous, inventive and a host of qualities yet out of reach of my understanding. Thank you very much for taking the time to make this wonderful machine and to produce the very well done video for all to enjoy. Kudos!

Thanks for putting this up Dan, I immensely enjoy your videos and learn a lot from them and hope you can be encouraged to share more.

The bearing at the beginning would be a cool desk toy.

It's not everyday that someone as successful as Dan shows his inner sanctum (home workshop) on youtube.. even his life story and philosophy of Creo is interesting.. I've been developing tech and machines in my basement for years now (since I was 23) and i'm close to finally go commercial soon so hopefully I can make money to buy bigger machines because the chattering and weak mini mills and lathes will soon be the death of me.. can't take in anymore to be honest!.. anyway cheers Dan, you're an inspiraton to us!

Dan, one of the biggest inspirations on this subject! In all your series i never heard you mention the use of metal filled epoxy for casting precision surfaces (on metals, ultra high performance concrete, epoxy granite or any other reasonably stiff and stable material). As someone else mentioned, a "perfect" flat, parallel or square surface could easily be formed by using special epoxy like Moglice or DHT, a surface plate and standard measuring equipment. Or to match a bore to a shaft and so on. For mating or bearing surfaces , but especially for air bearings, as there is no contact between surfaces, so the bearing properties between the materials are mostly irrelevant. Also you can mold in pockets, orifices, restrictors with dissolvable materials like wax or even 3d printed plastics. For example, experiments were made for mating a nut including all the air channels to a precision acme screw with Moglice, which were lapped to each other afterwards for a defined clearance, with some promising results. I'm just pondering what you could achieve with this method, with reduced or even without the hassle of scraping, lapping, grinding or machining surfaces. Also your choice of materials and methods of forming structures would greatly improve. I plan to make a couple of experiments, so i would love to hear your experience or opinion about it. Thank you so much for your content, saved me many years of unnecessary try and error, but also gives me even more inspiration for years of experimentation! much love from switzerland :)

You raised a good point, but epoxy granite can only be used where there is no wear, such as air bearings or non moving parts. It scratches too easily for all other applications. I considered it for the lathe, but the way wipers collect grinding dust and chips and would have worn out the ways. Even is the ways are air bearings you need to wipe them. BTW, it is a Swiss invention, introduced by the Studer AG grinder maker under the name Granitan.

I need more!!!! This was brilliant and the fact you built it yourself, with micron accuracy? Amazing. Id live to learn from you, brilliant work.

Glad to see you back Dan, I have learned a lot from your videos Hope you can find the time to share more. all the best.

Hey Dan loved working on projects for you at Creo! My first engineering co-op was there & did several more. Loved getting around people like yourself & others. My favorite time of the day was around the lunch tables listening in on rediculous engineering debates where each party was deeply intrenched on their hypothesis and would defend it to the bitted end 😂. The results in the labs were the only way to settle it!

This man's work is so beautiful I tend to hold my breath when looking at it. As an amateur machinist, I have never hold any tolerance tighter than a thousandth. This has been good enough for small o-ring grooves, heat-shrink fits, seals, seats for (commercial) ball-bearings, and so on. I have a professional machinist bro who typically does not have to hold any tolerance tighter than a "tenth". Dan, you are on a level so beyond what I am familiar with it is beyond my ken.

It's an amazing lathe. I only try to make air bearings once, when i build a Tesla turbine, and i fail miserably. The tolerances have to be very tight. You had a very clever solution to build the bed, does the viscosity of the epoxy affect the aligment of the parallels during the glueing? do you have to press the pieces with high pressure?

@dgelbart

Noneed for pressure, the weight of the granite pushes out the excess epoxy. The parallels are kept in alignment during curing via a matched pair of precision steel spacers. Very slow setting epoxy is used.

The bed and cross slide of an existing lathe is not accurate enough. You need 1um straightness and squareness. . What you can do is buy a used Moore #3 Jig Borer (under $3000 on Ebay) and mount the spindle instead of column. Several companies who needed high accuracy machines did that.

@@dgelbart Hello Dan, a colleague of mine has recently built a nice EDM machine as a side-project. He discusses a nice tip to get a wrapping-angle of >360 degree on a pulley here: kzread.info/dash/bejne/p6dnrcqNZ9WWYco.html (Channel-name: KZread --> BAXEDM). I think you'll really like it (and the rest of his video-series too, if you have the time - Mike has 5 videos in the series thus far). Regards!

@@dgelbart Dan, I must absolutely implore you to watch this video (flextures cut on a homebrew-EDM) kzread.info/dash/bejne/dZeIs9Gyj9eooJc.html

Totally porn .. I m jaleus with this machine, comparing to my hardinge lathe..

@@CBRFFan what do you mean with resolution? The reason I ask is that resulotion and actual accuracy are different things. After looking at their site for one of their modern machines the resolution on the glass scales is 0.01 micron, drives are 0.1 micron and it results in a accuracy of 2-3.5 micron in X/Z

@@CBRFFan I don't think so. Make a part with your lathe and then compare it on a AA surface plate with gauge blocks. See if you're within 0.1micron. My cheap caliper shows down to 10micron but the accuracy is 25micron (1thou). My micron glass scale has an accuracy of 2microns. So what you see on your display is not what you get

Micrometers that read in 0,01mm are sometimes calibrated with 0,001mm accuracy. Something that is reading in 0,001 or better may as well be 10 times worse than the reading. At any rate that accuracy requires flooding the whole machine body and screws especially with temp controlled cooling oil. If it doesn't have that, it's impossible to be so accurate consistently

Wow, that is a beautiful piece of engineering !!!

that air bearing is very interesting. 🤔 there is nothing like watching the air bearing in action compared to someone explaining the concept. 🥰 thanks smart Dan.

I thought my lathe was good..

Fantastic engineering . Thank you for sharing your work .

What a fine piece of work, well done!

I doff my hat sir to a master at his craft. thank you for sharing.

More videos on this would be awesome! Making an air bearing part would make my day!

We miss you your videos and your ideas even your inspiration to build better.

I don't have words to describe this machine, Its incredible .

nice clip, it gave me inspire for my home build mill project. thanks

Super nice lathe buddy! We need one like this for our maker space :)

I hope you put up more excellent content like this soon

Absolutely beautiful machine, and very well explained.

First-class engineering! Perfect explained!
