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!

[@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.

[@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.

[@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.

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

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@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.

[@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.

[@paulwomack5866]

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

[@Timeonabike]

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

[@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.

[@ckvasnic1]

Great Stuff Robin... Thank you! Thank you for your time and sharing your talents!

[@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.

[@simonsaelaertfurniture9883]

Good to see you again on youtube, Looking forward on what appears to become a highly interesting series. Thanks for sharing.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@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.

[@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.

[@Dans-hobbies]

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

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@brianevans1946]

Awesome video and very informative, already looking foreward to the next episode..

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@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.

[@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.

[@Ujeb08]

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

[@ROBRENZ]

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.

[@tpt100t]

I think I just got another education by you. Thank you for sharing you of your vast knowledge of precision fabrication!

[@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.

[@davidlee7319]

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

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@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.

[@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.

[@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.

[@zsigmondkara]

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

Really enjoyed this!

[@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.

[@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.

[@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.

[@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.

[@mikewalton5469]

you are truly inspirational, mission accomplished!

[@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.

[@andyash5675]

Superb 3 plate demo Robin. :-)

[@ROBRENZ]

Thanks, and thanks for watching and commenting.

[@djberg3483]

Excelent as always

[@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.

[@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.

[@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.

[@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.

[@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.

[@Alistair_Spence]

I really enjoyed this. Thank you.

[@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.

[@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.

[@FredMiller]

Just two words..... Awesome Thanks for sharing!

[@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.

[@ericharvey2968]

solid video. look forward to upcoming videos.

[@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.

[@metalmogul4691]

Another great video. This is sharing hard learned knowledge. Thank you!

[@ROBRENZ]

Thanks for watching and commenting.

[@metalmogul4691]

Acknowleging my reply means not only do you read them, but you are still showing that details for any kind of process matters. I will look forward to your next choice of video content. 19000 subscribers know what they like. Thank you.

[@pierresgarage2687]

Good idea about the series... You're sooo right about the time it takes to produce those videos.... ;) ATB, Pierre

[@ROBRENZ]

Thanks Pierre, and thanks for watching and commenting.

[@motorbreath22]

Man you are on another level, I wish you could just post videos all the time.

[@ROBRENZ]

Thanks, and thanks for watching and commenting.
