[@StefanGotteswinter]

Brilliant, great content there, thank you Robin!

[@ROBRENZ]

Thanks Stefan, and thanks for watching and commenting.

[@EdgePrecision]

I just barely watched this. Thanks! For the call out. I didn’t even know you watched my videos. I am so impressed with your technical ability. You do things I would be very hesitant to try. The caliper videos Wow! Your name of your video series is dead on. I am looking forward to your future videos. Again thank you!

[@ROBRENZ]

Thanks Peter, I think the same thing about the amazing stuff you do. You are obviously the real deal.

[@jonnyseim]

Peter, I was recently made aware of your channel as well. You both have been more valuable than my college degree.

[@oxtoolco]

Great title! I kept looking at that oil spot on your shirt....... Bravo my friend! In case you guys weren't paying attention to detail Robin showed a clue on how his Repeat-O-Straight-O-Meter works. I love how Robin just says stuff like, " Should be sub 5 microinch TIR, probably better......." End quote. Talk to you soon. --Tom

[@ROBRENZ]

I think that spot might have been from dinner. Thanks Tom, means a lot coming from you. ATB, Robin

[@simperous4308]

There are only 2 youtubers whose videos I watch the second I get a notification. This Old Tony, and Robrenz. And Rob is miles ahead when it comes to sheer skill and knowledge. Great to see ATD starting. I’ll be watching avidly!

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@Ropetangler]

Not arguing about the quality of the twoYou tubers that you mentioned, but you need to check out Clickspring!

[@alexgalloway7690]

I've been a toolmaker for 40 years, but have picked up so many useful tricks since discovering your channel .

[@ROBRENZ]

Great to hear!

[@dannymaciejewski]

Great video Robin! I’m looking forward to seeing how you will get those spindles to sub 5 millionths!!! Wow! Isn’t that 1/10th of a micron? Stefan will cry himself to sleep when he sees this...

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@Metallurg33]

Had to watch it 3 times, I would get so fascinated by thinking about one topic I would miss the start of the next. Great stuff!

[@FredMiller]

LOL me too!!

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@longlivepunk]

Loved it, Robin. Don't need any bells and whistles, just good informative content brings us all back! I for one am looking forward to more ATD's!

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@RayLautenschlager]

Perfect name for these shows and fits your approach to machining and precision.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@iainfletcher6388]

'...ultra precise, hopefully...' I think we all know there's no need for 'hoping' or 'luck' to achieve that! No substitute for skill and experience. Can't wait for the follow up videos.

[@braxtonec]

The three plate demo with paper stick figure precision instruments brought the whole concept home very effectively. You are an excellent teacher. Thanks again!

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@Neo7CNC]

Robin, You're a great teacher. Thank you for sharing your knowledge. All the best, David

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@SolidRockMachineShopInc]

Thanks for another great video and the shout out Robin. Steve

[@ROBRENZ]

Thanks Steve, and thanks for watching and commenting.

[@paulwomack5866]

Loving the (working...) cardboard repeat-o-meter!

[@ianjoubert7505]

Robin, thank you soooo verrryyy much to take the time to make these videos! I know you are a very busy man, and these videos are time consuming, but that being said, you must know you are a enormous inspiration to many people around the world! Wish I could give you 100s of thumps up! Thank you once again!

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@mrblack61]

The 'two footed twist gage' is new to me, such a simple quick to use tool! Cheers Robin

[@ROBRENZ]

Thanks for watching and commenting.

[@rodfrey]

Thanks for all your work in putting these out. It's a real gift to the world for you to share your experience (yeah, I'm sure the $4.87 payout each month is nice, but really....) The only complaint I have is that it's your fault that I'm reading the Foundations of Mechanical Accuracy, and now I regard my mill the same way I do an angle grinder.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@chrisj4570g]

Love it, love it, love it. Thank you for sharing your knowledge.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@mikemarriam]

Perfect name for your new feature. I admire your measured and thoughtful responses to your viewer's "concerns" which experience from other channel creators has shown are often expressed in a harsh manner.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@outsidescrewball]

Enjoyed Robin....honestly some of the info is above my pay grade....but I am always trying to learn and you are a great mentor...ATB

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@miamatti]

You and several other youtubers have inspired me to continually expand my breadth of knowledge and strive to be as good as I can be at whatever my career will be

[@ROBRENZ]

That is really encouraging to hear, thanks for sharing that.

[@douglastedder1694]

i watch these videos multiple times and dont get tired of them. seriously. its been said many times and im sure it will be said many more... but thank you. thank you for sharing your relentlessness with us.

[@jonnyseim]

Rob, thanks for your time. I have learned a valuable lesson from every video you have produced. I run a DMG MORI lathe with integrated Fanuc robot loader and ZEISS CMM 100% inspection. I make automotive components and “attempt” to hold a few tenths for 15,000 pieces a year. I appreciate your content and continually look forward to your next post. Thanks, Jonny.

[@ROBRENZ]

Thanks for watching and commenting.

[@yosmith1]

So happy to hear you're going to do these series! As always, thank you so much for sharing your experience and knowledge.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

Great video! Love the variety of content and the level of detail you went into with each topic. Thanks for putting in all the work to make these videos for us all!

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@Timeonabike]

Thank you! A great explanation of the 3-plate method.

[@SaltFlatMonte]

Fantastic demonstration with the foam blocks and paper tools. Looking forward to sharing this with my students. Great video and looking forward to the series.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@StraightThread]

Rich content, Robin. I enjoy your explanations of the subtle details, concise and accurate, just like the machining work you produce.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@andrew_the_machinist]

30secs in and I already like the title enough to hit the thumbs up! "Attention to Detail" is my motto. Say it a thousand times a day, as critic or encouragement to others or in my head to myself as the same.

[@ROBRENZ]

Thanks for watching and commenting.

[@Maxi-hs5nk]

Many thanks Rob, appreciate you taking the time to teach us! ATB Max

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@GaryGrumble]

The density of information on your videos is amazing. Thank you very much.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@riaandewinnaar5040]

Clearly described. Thanks for sharing your years of experience.

[@ROBRENZ]

Glad it was helpful!

[@EmmaRitson]

Awesome! lots to process there, I napped though the first time, and watched it again, hopefully i retained some. thanks as always for support and inspiration!

[@ROBRENZ]

Thanks Emma, and thanks for watching and commenting.

[@xxxmmm5942]

Does not matter how much one knows but how well he can explain it. So many of us will benefit from these series. Great job, Rob and thank you.

[@ROBRENZ]

Thanks and thanks for watching and commenting.

[@adamscholl3996]

Thanks so much for taking the time to share some of these projects on youtube and instagram. As a mehanical engineering student I've gotten an enormous amount of insight into the "why's" of what I'm learning and it's so helpful to get a peek at your perspective. All the best, -Adam

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@moeszyslack4676]

I saw the title and didn't know what this video would be about. What a pleasant surprise. I don't make videos, but I can only imagine how much time it takes to make one, especially these kinds of videos. Even though most of what you do and show goes over my head, it is a joy to watch and (try to) learn. Thanks Robin and I know I'm not the only one looking forward to more content!

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@intagliode]

Awesome Robin! Always learn a lot from you. You've been teasing me with all that cool stuff on Instagram for awhile. Nice to finally get a more comprehensive update on your latest projects! Keep up the great work!

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@billythebake]

Hey Robin, just wanted to thank you for putting up such a nice sampling of machining & metrology. Fun to get a glimpse of the world past the hotwrench, drill press, and angle grinder!

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@Dans-hobbies]

Excellent, another regular series to get addicted to! :-)

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@lancebaltzley4770]

Love what you are doing Robin, great named series.... Keep it coming!! thank you so much...

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@onecrisde]

Thanks for the visual representations as you explain complex principles. Without which, it would be impossible to understand. While I don't yet have the skill-set instruments or machines to execute that level of precision, I am certain the exposure to that knowledge will influence my work over time.

[@bostedtap8399]

Excellent presentation, and most importantly, true theory and method for geometric generation of accurate mechanical engineering. People also forget that there are calculations for the gravitational influence on optical light systems, for example using a theodolite. Fantastic teachings, and please keep up the good work.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@r.j.sworkshop7883]

Thanks Robin for taking the time to share your thoughts and tips. Even if your discussion points aren't something that I can use in the near future, it always makes for a good thought exercise. ATD=perfect!

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@PracticalRenaissance]

I love it, Robin! Great video and I'm excited to see more in the future!

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@ianbertenshaw4350]

All i can say is man it is good too see you back !

[@ROBRENZ]

Thanks for watching and commenting.

[@ScottGMerritt]

Thanks, Robin. You are one of the best!

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@adamstagnaro]

Great video as usual Robin. Love the quick tips part.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@Volcker1929]

Props on the props, they were simple but really helped explain the concepts. Thanks you very much for taking the time to make these videos. This is a great format and I learned a lot.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@lornie212]

I like this format and subject matter....... thank you Robin!

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@joshua43214]

Teaser...ugh...Really looking forward to this. BTW, great idea for the new series, perfectly named.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@danvandertorre6349]

info is the best thing anyone can give to another so yes we aprsheate your channel big time Rob thankyou

[@jeffreylehn8803]

Well done Robin , I enjoy the videos that you make .

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@ActiveAtom]

We are learning a lot from Steve and family at Solid Rock grinding knowledge is really way up there lots to learn from them and so much more that I thought I knew and did not and now we do.

The best explanation ever!! Thanks

[@zsigmondkara]

'I don't think so, Tim' perfect impression xD Amazing channel, keep up the good work!

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@Factory400]

"In the sub 5 millionths TIR range......." Whaaaaaat? That is not precision. That is PERFECT.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@davidlee7319]

Looking forward to these. Attention to Detail is a great name, very apropos.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@bkoholliston]

Very nice! Much of the info is straight out of Foundations of Mechanical Accuracy but not widely known, so it is great to see it presented.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@886014]

Thanks Robin, I think that was one of your best videos. Many people are confused over 3 plate self-generation and the requirement to also rotate the plates, and you explained that very well, even managing to slip in a heigth reference, though minus one point for then slipping back into English, ha ha. Using a twist gauge was brilliant and one of those "doh!" moments and I use a level and never thought of doing ways that way. It will be very interesting to see that spindle coming along, it sounds quite remarkable. Thanks for continuing to raise the bar.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@belair_boy6035]

Ten thumbs up, I can't wait for all the up coming content. Please keep up the good work.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@Ujeb08]

Rob, thanks for turning us onto some good new channels!

[@ROBRENZ]

Thanks for watching and commenting.

[@luckenbachmachineworks7000]

Thanks for taking time to share your insights. To a novice like me they are very eye opening as to the precision and accuracy that is really possible to attain in machining. I have a looong way to go!

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@johnmcdonnell6109]

Great explanations and demonstrations! Really enjoyed the lesson!

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

Thanks for sharing, as always I'm blown away.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@junkmail4613]

3:14 to 7:23 Very clear and succinct description. Thank You so much. About 1961 (I was about 10 years old) My dad took me to Bell Labs in Whippany NJ (where he worked) to see the first ever laser length measuring research device, a 2 ft x 3 ft x 15 ft slab of something (weighed tonnes) supported on fulcrum knife edge type supports(again I was only 10 relative to my grasp of the supports and process), and he showed me that just walking on the concrete floor next to the device changed the laser measured length. I was so impressed then, but I now find it absolutely incredible, and you sir take me back to the wispy times of my own pre-historical memories. I believe you "do measurements", test and verify, and make very real in a realm so inconceivable and incomprehensible to the average layman, that is as astronomical, and Hubble's constant, are so far away from "Pass the Salt Please" This poor example may make little sense to you, but I'm trying to express that I am extremely impressed, without insulting your incredible integrity, by my humble offering. I had forgotten, if I ever knew, that people like you exist. Again you make real, and test and verify, things that others I'm sure have no concept of.

[@ROBRENZ]

Thanks for the very kind words and glad I could bring some good memories back!

[@junkmail4613]

All credits to you! Thanks Again.

[@timtrott4145]

perfect name, good format , I enjoyed the informative method, I wiiill look forward to the next episode.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@unknownapprentice625]

Like the new series, details do make the difference! Also more opportunity for the Apprentices in the audience to learn :) Thanks Robin.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@nothermarkgnomex]

Good content! Looking forward to learning more details to pay attention to!

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@RGSABloke]

Robin, between you and Lipton my brain is going to explode, you guys make the very complicated very understandable and for that I thank you both. Kindest regards. Joe.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@arnljotseem8794]

Excellent content, and great format. I learned some new words and concepts today. I really like your other in depth project videos also....

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@literoadie3502]

The first time I've ever heard any of the KZbin channels mention Joe Pieczynski. I was beginning to wonder if people had some beef with him. I always thought his content was fine, certainly better than some other guys that some of the bigger channels often praise.

[@ROBRENZ]

No beef with me! He's a great guy with great content.

[@mikewalton5469]

you are truly inspirational, mission accomplished!

[@ROBRENZ]

Thanks and thanks for watching and commenting.

[@andyash5675]

Superb 3 plate demo Robin. :-)

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@michaelschnock3998]

"I dont think so , Tim?? " lol --- well placed small joke good content, useful information and as every time well explained . Thank you for sharing, i ll wait for the next episode .

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@Krzys_D]

Your attention to detail in this attention to detail video has really good attention to detail.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@josephwilson6651]

Some former coworkers have lamented the loss of American precision machining, and the appearance of offshore(Chinese) measuring tools, which mimic American form factor,are much less expensive, and while not as precise come very close, but miss the mark.I can now direct them to observe your channel for their precision high.As I have also done. Thank you,Mr. Renzetti

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@cnc-ua]

Thank you, Robin I miss these types of videos gathered together. Instagram style has lack of comprehensiveness

[@RRINTHESHOP]

Thank you Robin, This will be a great series.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@curtisvonepp9716]

I've been watching Mr. Renzetti for years had a dream I was his equal more or less and woke up shocked he shifted to a higher GEAR.

[@CalebNixon1844]

Really enjoyed this!

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@rlsimpso]

Brilliant. All I can say is, thanks. More please :)

[@ROBRENZ]
