The level of detailed explanation and instruction Stefan goes to in every one of his videos is nothing short of excellent.
Sure glad t see you're coming out with more videos, you're likely my favorite machining RUclips channel. Appreciate the knowledge you pass on!
Nice to see Stefan poke fun at A-Bom's cooking & getting free stuff YT channel !
I really appreciated the micro-machining. Seeing the difference the cutting oil makes was amazing! Thanks!
Is no one going to acknowledge those luxurious lox? Hair game on 80s heart throb level. ❤️
Cosplaying as a 80s hair metal band lead singer soon ;)
I am a simple man, I see a Stefan Gotteswinter video; I smash the like button. Also: first.
🏆first prize
I really liked the subtle welcome message bite into another well known RUclipsr machinist 😇
He's become quite the advertisement channel... 🙁 Loved the older stuff where he made large machinery replacement parts, his own tooling or any fabrication really.
He has a great work ethic and does things one way and only one way: the right way.
But it's just become too rare that he applies his skills to meaningful work.
I'm not wishing him unwell. It's his channel and it's cool he gets endorsements. It's just not for me anymore.
Really digging Cutting Edge Engineering Australia though!
He wasn’t referring to Abom.. it was Adamthemachinist I heard..
Unless I missed it which is distinctly possible..
That "if you did that in my shop , id fire you" comment was great. One thing the internet and access to the wider world has taught us is: There is only one way to do anything
I'd bet the farm that guy's never had half the machinist Stefan is working in his shop.
"...I'd fire you..." Yet another bold proclamation from someone that's demonstrated no ability at all to the world at large.
@@Steve_Just_Steve He doesn't need any experience or have access to machinery, just a well packed bowl of marijuana and some imagination.
@@Steve_Just_Steve 👍
@@bobweiram6321 He/she was simply lurking in the comments section waiting to say something profoundly stupid at just the right time.
That Cratex looked like a handful of bitumen and gravel off the front street.Love it.
Excellent ! * When machining , excellence should be the aim ;) ( Stefan is absolutely one of the best YT channels to watch for gaining practical knowledge of this fine art ! )
Add me to the list of those who love your long format videos - the mixture of processes is extremely well presented ! Thank YOU , Stefan ! ! !
love this stuff! no BBQ. no DIY home improvements.
Oh be nice. Even Stephen has shown home improvements (yet he kept it captivating) but he hasn't monetized his RV and bbq.
No cornball homespun wisdom, or showcasing scantily-clad wives as clickbait, no irritating "friends" showing up, no gardening tips, no dogs, no ghastly tattoos...
I’d watch if he made an auger and drive for a pellet grill
@@larryw5329 why be nice ? At Abom's level, youtube isn't just sharing your passion its a nice revenue stream. Maybe that's the root of the problem, the money changes priorities for some creators. But philosophy aside : Abom isn't providing his content as a charity, he is trading our time for his revenue. Padding out the slightest thing over several videos is just wasting our time. And when the interesting machining content drops too low .. we should just stop watching.
Stefans joke at the start "blah blah..not really this is a machining channel" hits the bullseye. That's why people interested in machining hang on every word from Stefan and lost interest in Abom. ..
.. Plus of course Stefan is also one of the most skilled craftsmen out there (none of us should try to choose between Stefan & Robin) .. we learn SO much just listening to their calm elaborations of what and why. This is what we came for. Distilled wisdom. THANK YOU FOR SHARING STEFAN.
@@davesmith9325 Well said my friend!
I clicked like before even watching the video, because I already know I’ll like whatever you put out on video lol
I do the same. 🤣
Always👍
A wonderful start to Sunday here in Australia.
Heater on, sun shining through the last of the vine on the porch.
Stefan Gotteswinter making the joke with perfection.
Heater? Did it drop below 25?

@@thosoz3431 lots of machining nerds around the dandenongs ;)
@@ryebis While I don't count myself amongst those hallowed few, yes you're right, there are quite a few. Went for a cruise on a friends beautiful steam powered 20 ft Couter boat on Blue Rock Lake recently. The engine , boiler and all mechanicals, hand built here in Emerald in one of the most impressive private work shops I have ever seen, (including on RUclips). I know of 3 guys with milling machines within a couple of steets from me.
Stefan can totally geek out and still be cool. He's a natural!
Geeks are the coolest people anyways :-D
I like the little bit of fun your adding to your videos. Keep em coming !
Wie immer - Ausgeseichnet! Vielen dank fuer deine arbeit. Mit Freundlichen Gruessen von Romeo, Michigan, USA
I particularly liked your grinding wheel summary, as that’s a topic that seems to get complicated in a hurry. Thanks, Stefan
Edit: also thanks for not demonstrating your barbecue. 👍
The micro-machining was fun! Also to those who don't like using the carriage to drill, ream, tap, die cut, etc.--how to they think it works on a CNC lathe? That worm-drive chuck and floating reamer holder are made for the CNC lathe world. Some people are just stuck in the past I guess. I always enjoy your channel--so good.
Anyone who wants to exceed the usual drill chuck grip without shelling out for a CNC worm drive chuck could consider a second-hand Jacobs Ball bearing Super Chuck. I regularly power tap up to M16 in stainless and occasionally M20 with my 3/4" capacity one of these, and it has never slipped. Nor broken a tap, because I made up a passive (ie free spinning) spindle which plugs into the (Morse #5) tailstock taper, which I can prevent from rotating using the steering wheel off a go-kart (quite big diameter), which I can easily hand hold at opposite places on the grippy rim, but allow to slip the moment the tap binds or bottoms out. (Like an extreme 4WDer, I never put my thumbs through, as the spokes might remove them.)
When I engage the reverse clutch of the headstock drive, I can also hand spin the tap to rapid retract.
It works better than I hoped and probably better than anyone reading this would imagine.
I love watching the little tiny precision parts. I was wrestling a 1000kg part on the mill table I couldn't get to sit where I wanted during this video so I was a bit envious of your work envelope at the time. LOL
No need to rush the video. I enjoy the discourse Ted. Nice job.
Love your sense of humor. "Highest precision" at 17:13 had me in stitches :)
Edit: Thank YOU for sharing your knowledge.
A previous owner of my Bridgeport clone somehow managed to sheer off the drive pin and i've been running it for years with no drive pin, i often do very heavy cuts and i've never had any problems with it spinning the r8 in the spindle
A series 1 Bridgeport with an R8 taper? I didn't think they had a drive pin, but an alignment pin.
@xman charl It's not a "drive" pin, it's an alignment pin not a drive dog/pin. Series 1 don't have a drive pin. I have a Series 2 with 40 taper spindle, it's has drive dogs.
Previous owner sheared the pin off in mine. I fitted a new one. Nice easy job. Whether it does anything useful I rather doubt.
@@Steve_Just_Steve collets are supposed to be concentric so an alignment pin is completely redundant
very good jobs stefan..thanks for your time
THANK YOU STEFAN, SO IMFORMATIF, AND SUPER CLOSE UP SHOTS PLUS HOW YOU DID IT. REGARDS RICHARD.
Thanks for the shout out Stefan. You will love ID grinding on the surface grinder with a setup similar to mine. Enjoyed the video, great content.
Steve
I had a drill press where the Jacobs drill holder was dropping out constantly . The easy fix was to run the press while holding the Jaobs and a litle bit of grinding paste. It has never fallen out since.
Thank you as always for the ongoing education; I might be a freshman in a grad class but I appreciate it just the same!
This is not an engineering nor a trade. Your videos are an art
Thank you Stefan. Your videos are eagerly awaited and never disappoint; we learn from each of them. Live long and prosper!
Thanks Stefan - excellent as always. I really enjoy and appreciate the masses of knowledge that you share.
I always enjoy your videos and I am thankful for you sharing your vast knowledge with all of us!
thank you VERY much for sharing. you are invaluable to many of us.
Hey, Stefan, thanks for all of the stuff you share with us! It's always interesting and edifying!
Much appreciated! :)
Good video, lots of good ideas. I've never come across the floating reamer holder, great idea
Excellent, as always. Thanks!
Super. Dobra dokładna robota. Ciekawy pomysł ze szlifowaniem stożka drill press spindle. Mnie też to czeka . Pozdrawiam.
Great video! I really enjoyed your time discussing the grinding wheels. I see no issues with your and Robin’s drilling with the carriage. I would expect those who do have a problem believe the world is still flat.
It IS still flat 😎👍
Awesome video production/discussion/demonstration/builds….enjoyed all subjects and lessons
Love the drill press spindle rebuilding masterclass!
Glad to see a video, you are my absolute favorite machining channel of all time.
You're a very talented machinist and you have the exact same accent as my family from Hemau.
Brilliantly instructive as always.
Great as always and an inspiration for all of us to be as precise and spot on as we can be.
another awesome shop talk thanks Stefan many useful tips in there as alaways
OMG, Sunday gold
Blimey this guy is resourceful!!!. Makes me feel quite incompetant.
Thanks Stefan. An hour well spent! I always feel slightly freaked out watching hard turning with an interrupted cut. The inserts you are using must be high quality.
Regards,
Preso
Love your show keep them coming. Thanks
Awesome update! I especially enjoyed the walk through of surface grinding wheels! I’d love to see a tutorial about relieving the shank of an end mill on the surface grinder sometime or any other surface grinder teaching.
Awesome as always Sir! Thank you for sharing!
Great info and project. Thanks Stefan.
Love your teaching mode. No , really, "Thank you" !
Thank you for teaching us all so much!
As amazing as those plungers look under my microscope, the footage you captured making them is awe-inspiring👍👍
Speaking of inspiration, I found that I can hold a cheap turret lathe chuck in the 16mm boring bar holder that came with my Chinese quick-change toolpost, after watching your last video - it's really upped my game, thanks. (Now I just need to discipline myself to record offsets on my DRO...)
Thank you,
Just thank you for making your videos.
It's fun watching you make small stuff
My work is on a larger scale, no magnification required!
Stephan, Thank you - I am always extremely humbled and inspired by your dedication and precision. Again - Thank you 🙏
Of course I'm "still here", it is fascinating.
Your videos are always interesting. Thanks.
I always had a suspicion that you were a metalhead and now I know for sure that you indeed are one.
Up the metal!
Love the idea of turning under the microscope! That setup looks awesome! :D Congrats for what you are doing and thank you for being my source of inspiration!
Good stuff Stefan, enjoyed!
ATB, Robin
Thank you, Robin!
Love the microscope phone clamp, Great to see use of different lathes for each job, the lorke watchmakers. would love one but a diy ER collet extension in beaarings is as far as ive got. Love the work.
It’s funny, I have some of the newest, most advanced CNC machines ever made at my disposal and I have brought stuff home to run on my late 1800’s Waltham lathe for the exact same reason.
Thank you. Great content, great tips AND a very good technical quality of filming and editing. Much appreciated.
You've really upped your game since I started watching your channel! Thanks for the great information about things I'll never see in person.
As always buddy it’s a pleasure to spot one of your vids on my feed
Great to see yet another inspirational video from you.
I always take something away useful and found talk on grinding wheels very handy as was debating which wheels to set myself up with.
precision barbecuing Stefan style would go down well with all those machinist/barbecue fans out there I’m sure😉
Hello Mr. Gotteswinter,
Nice to see the Lorch in action and all the micro machining was enjoyable viewing, thank you.
Take care.
Paul,,
Love your work mate 👌🤣
I hope you know how much your ‘extra work’ ( video/editing) is appreciated.
Thanks
And Kind Regards,
Robert
Thanks again for putting out great content.
Thank You, Stefan... Another very interesting video. I always enjoy your content and seeing what you have created.

You had me at "ER collet chuck with integrated floating tap holder."
Thank you Stefan.Love your videos always and an inspiration for all of us
Best channel on utube, luv it, many Thnks for sharing your knowledge and "Common Sense... (you know that stuff that is not given out anymore lol, )
& time... I wish you all the happiness in the world. Phil
Always a pleasure to watch your films. Thank you for charing man.
No, thank you Stefan for the great content 👍
If i remember right we used dykem applied @ like .0005" to .001" and permatex @ .001-.0015.... depending on the seal angle among other features like torque make up on threaded connections and shit. I know it's another world but everything has its place. We had bluing blocks that were nothing but gage blocks with different finishes or micro steps across one plane which u then applied a dab of either bluing and swiping it with a matching block that came together with the bluing blocks as a set revealed the ideal/proper display of how the correct thickness visually looks after being applied correctly.
I've made i to the end , was very good in depth grinding video ☆☆☆☆☆ ...and yess i to Will be back to 😁😉 !

It was good to see you using your watch makers lathe! I wasn't sure if you still had it.
"Truly not bad" - brilliant!
I use one of the Andonstar "microscope" camera things for making parts around 1.5 mm diameter on my old Colchester 1800,, but I miss the 3D view of the optical binocular scope I use for electronic component assembly. After seeing yours, I'm tempted to get a cheap Amscope binocular scope with a 0.5x lens extender and make a mount for the lathe.
Yeah, I was thinking about getting a cheap optical microscope for beeing used on the machines, the Leica is a bit expensive in case of a crash event.. :D
Thank you for making these videos. I learn so much from every single one, and always look forward to the next one!
Excellent video man...👍👍👍
Great video Stefan, always watching and learning👍
wonderful as usual Thank You

I’ve been wondering where that little lathe went! Awesome to see you pull it out. I understand it’s not practical for most of what you do, but it’s such a cool piece of gear.
In the any shop should tap in the shoulder and say hey man that is nicely thinked and carry on 😀
For some thinking out of the box and making things happened.
Never could fire someone who thinks it own mind. Things can be made so many ways and that is beauty of shearing content any social media 🤩🤩
Thnx again great small talk content 🙂 🙂
The cat peeking in the window was pretty cool.
A friend 3d printed that for me :D
Thanks for the lessons. I always learn something useful from these.
Thank you love the long videos
Really like your new haircut! Very manly, which I would think that you might be. The depth of your knowledge always impresses me, although it makes me wish that I had a couple of additional synapses that were firing. Always a joy to see a new Stefan video.
Those die holders look awesome. Maybe a good project for my lathe at some point.
I'm glad you didn't show us your gate project. Useless apart from blocking your path.
As usual though, I learned a lot. Thanks. I have never seen a morse taper wiper before.
Yeah, you can just walk by it on the side. Stupid project :D
Nice to see you as always. I actually thought you might show us a barbecue 😅
Beautiful work!!
Thank you!
Thank you for this video.
Nice job...good to see what you are doing
Some great information there, as always. Thanks.
The Schaublin catalogue lists 6000N as the axial clamping force for an ISO30 ATC spindle (belleville washers pull force)
Great video Stefan..... :)
I would reprimand any machinist that did not watch your videos to learn!
If you know the capabilities of your particular machine properly then any process that is proved to work is acceptable. Including drilling from the carriage which I do sometimes too. That learning process takes time and thinking.
