I am "robinrenzetti" Instagram lots more content there!
That's a slick setup for sure. All can think from your videos is that you must have a fuck ton of patience. My shop made tools usually follow the "this is only temporary... unless it works" format.
Thanks and thanks for watching.
I am a machinist with 40 years of trade experience and I also have a BS in Mechanical engineering. Your comment on machinists thinking like mechanical engineers is one of the greatest tips I have ever heard for anybody working in the machining trade. Getting into the habit of visualizing the effects of stress and strain on a machine tool or work piece (especially during set ups) can be one of the best methods of achieving the desired results. This video is an excellent demonstration on how to approach set ups and machining ops. Explaining the chuck stops is an added bonus. Great job Robin.
Thank you!
About a week ago I left a comment about making the adjustable chuck stop. I used it the other day to square up a 2 inch washer (1/4 inch thick). That item made it so easy to set up and machine and was able to hold a tight tolerance. With practice I know I can better. What a great idea. Again thanks for sharing.
That is awesome!
I'm really enjoying your discussions. did not mind at all there was not chips flying. The thoughts and promises behind being a good machiest really interest me. Thanks for taking the time

Thanks Will and thanks for watching and commenting!
Robrenz, you are THE MAN. Thanks for sharing your knowledge!
Welcome back Robin.
Whatever you decide to call the show, please keep making these detailed and comprehensive episodes too. I watch and learn from many YT machinists, but your videos provide a unique perspective on the thought and action necessary to do precise, accurate work.
I don't kid myself by thinking I'll ever be able to work at your level (let alone 25% faster :-) but seeing what's possible inspires me to try harder.
Thanks and thanks for watching.
Actually, I don't care what format you put out. As long as you share your knowledge and experience the planet benefits from it.
Was very happy to see a new video from you, sir!
Thanks for sharing
Thanks and thanks for watching.
This is like a master class for machinists. Great content. Please do the video on thinking like a mechanical engineer. Your attention to the details and clear explanations make you videos a joy to watch. Thanks again.
Thanks and thanks for watching.
Your technical, mechanical engineering approach to machining is unique to RUclips and I find your explanations to be thought-provoking. I look forward to your Engineering for Machinists video(s).
Thanks and thanks for watching
Thank you so much for this. I really like all the small tips like using the case hardening compound and showing how you set up the screws on the stops using the indicator.
I love to see how you had a problem and solved the problem. Thats quality work
Great to see you back Robin. Your logical, methodical, deliberate approach to your work is refreshing. It's very much how I like to do things, though it certainly isn't at your level. Efficiency is important because time is something we can never get back so it's never good to waste it.
Thanks and thanks for watching.
That was or is probably the best 30 minutes I will spend to day getting educated on precision work and set up. Well another project to put on my todo list. Thank you for sharing your knowledge.
And +1 for a mechanical engineering for machinist video, really enjoy the depth you're willing to go on a topic
Agreed
Agree as well. Your meticulous attention to detail is gratifying one of the reasons I love your videos.
+1
Hey Robin,
Great video! I particularly like the last example tweaking in a longer shaft. Glad to see you back on the video train. I think I'm going to spray paint my chuck stops black now and hide them in a drawer.
Talk to you soon.
Tom
Hey Tom,
You know there is nothing wrong with your stops and your design easier to make and will probably be copied much more than mine will. You have radial adjustment and screw locking so they work just as well. Don't deprive the community of seeing a just as functional easier to make design.
ATB, Robin
"ROBRENZ notes from the shop". Rob, you could call it anything and I'd watch. There is always so much good information in your productions that I usually watch them repeatedly. Anyone with an 'Oscope in the background needs to be listened to.
Thanks and thanks for watching.
Hi Robin,
I have been eagerly waiting for your next video and it was very much worth it! Your craftsmanship and professionalism is truly outstanding. Such a pleasure to watch. Thank you very much for your effort, time and passion!
Have a nice day!
Aron
Thanks and thanks for watching.
I'm glad Tom sent me here! Nice work. Loads of information without unnecessary repetition.
Thanks James and thanks for watching and commenting!
As one machinist who makes a living doing this to another. Thank you! for this idea as soon as I get time I'm going to make some of these for my chucks. This would also work good in a 4Jaw chuck to get the face run out true without having to tap on the part.
i respect your channel and worth ethic, you are truly one of my favorite on youtube. all the best
You are welcome and thanks for watching
You and your fellow machinist who also does this for a living could pass for brothers.
Great video addressing multiple fixture setups. Deflections in clamping can easily get you into trouble if you aren't careful so good to point that out and ways to address it.
Thanks Brian and thanks for watching
You're not just Robin, you're the Batman! Great tools you made. Thanks for the video.
Thanks, and thanks for watching and commenting!
Hey Robin, a very professional way that you do things. I know that its your work and I very much appreciate you taking time to explain the reason behind it. As a hobby machinist I will look at the projects from a different prospective now. Thanks and God Bless Ya, Dave
Thanks David and thanks for watching and commenting!
So glad your back on the air. Have been a machinist and toolmaker for 40 years and I learn something new for every time I watch one of your videos. Great stuff!
Thanks and thanks for watching.
Another great video. Incredible the way you never seem to miss the smallest detail. Thanks for sharing.
Thanks and thanks for watching.
Odds and Renz. Thanks for sharing your knowledge, yours is my absolute favorite chanel on RUclips. So many gems...
Thanks Jacob and thanks for watching.
Very useful discussion of design approach and issues on a VERY useful tooling application. Thanks!
You are welcome and thanks for watching
Cool stop block system and as always your videos are detail oriented and worth the "time" to watch :) Thanks!
Thanks and thanks for watching.
you have excellently presented your ideas, as usual
Thanks and thanks for watching.
Thank you Sir, very detailed explanation and information. Gets a hobbyist to challenge his thought process and ask himself more questions about efficiency and tooling mods.
Thank you for explaining and showing clamping force. I really learned a lot. Thank you!
Thanks Zane and thanks for watching and commenting!
Brilliant, an engineer-machinist you are Sir.
After 35 years in business, I do think like an engineer (without even realizing it).
Thanks for the kind words and thanks for watching.
Rob, I'm so glad to see back making videos to share with people like myself who have so very much to learn. Your professional level attention to the details, communication skills and shared thought processes are fantastic. So information rich that I'll continue to learn from them for years. I'm not the most creative naming guy. That said possible names for your none project video are: Shoptalk with Rob #?, Shop Time with Rob #?, Rob's World #?, Rob's World: Updates and Reflections #?, Shop News with Rob#?, Picking Up The Loose Ends #?, Tightening Up The Loose Bits #?, Rob's Food For Thought #?, Tuning In Session #?, OK enough of my stream of unconsciousness. Thanks again for sharing lessons/perspectives from your world of precision metal working.
Thanks and thanks for watching.
Hi Robin,
I was sent here on Tom Lipton's recommendation.
I really like what I see and have subscribed. I'll be rooting around in your archives, so if you hear me back there, don't worry I always put stuff back where it goes.
Thanks
Thanks Jerry, I will be checking and thanks for watching and commenting!
Excellent! Thoughtful and effective design and fabrication. Your approach is especially laudable for me. I spent many years working in academic instrumentation shops and greatly appreciate your skills and ability to communicate. Thanks!
Thanks William and thanks for watching and commenting!
Robin I'm really happy I saw this video, I mean I get excited only because I haven't bought my lathe yet, and I've been really looking for one, but in the mean time - all these tips and helpful segments where you explain why you set up your lathes and machines a certain way only gives me more incentive and makes me more eager to get the lathe, and get to work. Thanks.
Thanks for the very kind words and glad you are enjoying the content.
You have some great ideas. I admire your logical approach to solving and designing. My idea of problem solving often involves panic.
Thanks and thanks for watching
... or a BFH ... 🔨
🙄😂
I watched this video years ago and now im gettong back to it again to be inspired to do my own chuck stops
Best machinist on RUclips.
I doubt that but Thanks John and thanks for watching and commenting!
Nice to see you back Robin, like a lot of my collegue I really appreciate this design, it's very nice how you use it to square the part to the axis make it very versatile.
Thanks and thanks for watching.
Happy to have you back. Totally agree with you on thinking like a mechanical engineer and any guidance is much appreciated. I use SolidWorks as well but more on the simulation/stress analysis side of it. Love to see how people use the package. Thanks.
Thanks and thanks for watching.
It's great to view and learn from another one of your excellent videos. Your attention to details which improve speed and accuracy is amazing and reflects many years of experience.
Thanks and thanks for watching.
Thanks Rob. as i get older i realise lately that time matters a lot. i am trying to be more efficient but its hard work to change.
You are welcome and thanks for watching.
Good to see more content that matters, something to learn from. And as far as Tom & Adams shop talk about gifts and viewer items goes less is more.
Thanks and thanks for watching.
Very useful tips. I will see if I can use these on my 3 ,4 and 6 jaw chucks.
I wish more mechanical engineers would think like machinists! :)
Came to this channel from Ox Tool and have now subscribed! I especially liked the discussion about the deflection of the disk upon tightening, well done Sir!
Thanks Bobby and thanks for watching and commenting!
Thanks for a video packed with useful tips and information for me as a hobbyist.
Personally i like to follow Adams SNS since I have followed him for so long, and think of him as someone I know. Not everyone wants to be this personal in the public arena. I say you should keep making good quality info packed stuff, like you have in the past, and do it at your own pace. Whenever you have time and content to make a new video, I welcome it and will be there to watch and like. Thank you
You are welcome and thanks for watching.
Absolutely fantastic video. Great information, presentation, and cadence. you are setting the bar quite high for the rest of us.
Thanks Noxious Green and thanks for watching and commenting!
A whistle notch. I love it! Love all your videos❤
Thank you for coming back, you are an exceptional craftsman. I really enjoy how you present the logic of your decisions and the insight of your years of experience.
I would like to suggest "ROBRENZ on the whiteboard" as a title for your meatloaf. Grab dry erase board and lay out the topics for the talk. Maybe have it build up some topics over time, then start with a clean whiteboard after the talk happens.
Thanks for the kind words and thanks for watching.
Nutz by Robin. Robin's Nutz. And Boltz. Doing it Robin's Way. Robrenz Makes It All Better. Cool Hand Rob.
Brilliant work, glad you're back!
Thanks and thanks for watching.
Really glad to see you back in the saddle and having time to make more videos. Looking forward to the next one.
Thanks and thanks for watching.
I really enjoyed this videos content so much I just made the one with the stop bar and different size diameter stops. Since my lathe is smaller I tailored it to fit my needs. I am new at this and look for projects like this to make. It was fairly easy and will be something I can use. Thanks so much.
Hi mate. It's the rubber band on the Kurt vice all over again. That's for the collet back stop that is. How bloody simple is that and yet how many engineers will have thought to do something like it. Like I say, it's the rubber band all over again. Infuriating. ( O;
The screw jack system is purely ingenious. All the small details only come with years of experience. I liked you showing the deflexion of that plate in the chuck. It's logical if you think about it but I did not gather that the deflexion would be that much in a chuck.
Oh and welcome back.
Thanks Marcel and thanks for watching.
Great video! Attention to detail is amazing! Appreciate hearing how valuable efficiency is in a job shop environment! I can't agree more!
Thanks Ben and thanks for watching and commenting!
Glad to see your back and I hope all is well for you and family. Its always interesting to see and hear the thought process behind designs and you attention to detail is great.
How about Vui Tui time with Robyn. i.e Vui Tui (Vooee Tooee) is a quick reference/book/folder for correct operating procedures. A common Aussie military term. Or "Inside the mind of Robyn" Shop talk. or Shop wisdom with Robyn.
All the best.
Bert
Thanks and thanks for watching.
Nice job Robin those are really slick. That is a great idea about the 5C stop I might have to make one for the lathe here.
Thanks Bill and thanks for watching.
Renz' Cents? Renz' Sense? Thanks again for the details you've thought through and shared with us. I don't even have a lathe but learned plenty from your process.
"Robin eggs" hatching ideas. Great video sir, glad to see you back.
Thanks and thanks for watching.
nice to see you back always learn when i watch you
Thanks for
the advice I am only a hobbyist but I have made a lot of your time saving
attachments as with another sight Joe Pie I class both of you as master machinist
and if I can achieve in making my parts that bit better by using tips and
tricks I fined here then imp better for it thanks very
"Robs quick jobs" would be a good headline for your new video series.
As always a lot of interesting stuff.
Thanks for sharing :)
Great explanation of deformation in a part due to clamping pressure. Sometimes these things aren't obvious. After all it is metal your clamping on. Thanks for another very informative video.
This a level of detail I can really appreciate! Thanks Robin!
Thanks again Keith and thanks for watching and commenting!
Hi Robin,
Very happy to have you back, I was seriously thinking you bailed out to never come back... ;)
I' watch your channel for that you put out serious content that doesn't need the "Xtras" to be a solid channel... You can read what I think about in Rob Mckennie's thread.
In this type of video you give in a short and concise description of the devices and more of those little fine tuning details that makes a so much better part in the end, this is why I'll be back every video of your's.
Welcome back and all the best, Pierre
Also I like saving my 25% on watching videos.... LOL
Thanks Pierre, I missed making the videos and watching videos.
All the best, Robin
as a freshly minted mechanical engineer i would say think like a machinist when your engineering ;) you guys are so much smarter than me.
Both directions are very valuable Garrett. You learned about simultaneous engineering and knowing machining/manufacturing processes sure helps to not design excessively expensive products.
I found your channel via Stefan's site, you have some interesting work .so thank you for sharing and I look forward to being a regular viewer.
Thanks Steve and thanks for watching.
We missed you.Great video.
Great video/discussion/build, made my day to see you again on a new video! ATB
Thanks Chuck its good to be back and thanks for watching.
ATB, Robin
Hey Robin - glad to see a new video. It's good to be busy, though!
My submission for a catch-all title: Shop Think. You're exceptional at discussing design elements, functionality, problem-solving; or as you mentioned, the mechanical engineering informing machining; thoroughness of your process; mechanical reasoning. Just seemed like it might fit your style.
Thanks, as always!
Thanks and thanks for watching.
A master class as always!!! Thanks Robin!
Thanks and thanks for watching.
During High School I worked at job shop. The very first machine I ever ran on the job was a Hardinge Turret Lathe. I loved that machine. I'd love to have a Hardinge Tool Room Lathe one day.
Worth the wait, every minute of it.
That Hardinge taper nose sure needs to earn one's trust. :-)
I don't care what you call your show, but there is hardly an item in your shop that isn't interesting.
It's so nice to see this attention to detail, getting everything set up just right for efficiency and quality of work.
Too often you see men only looking how much money they can get out of tools before they are all worn out, with little interest in improving something that already does the job. Even in one man shows where this should come natural, some folks still work as if they are just putting in hours for the man.
I might be more use with that DA1855A there than your machines, but it's the same in every profession. I always say not all minutes are made the same. I'd rather spend a bit of time on improving something in my environment, and shave that time off a repetitive job. It will pay for itself and even if it doesn't it sure makes work a lot more interesting than just getting on with the same old.
Some day you need to explain about the electronics side, for example why you have that 7k scope as your avatar picture but it doesn't appear on your bench.
I am an electronics wannabe. check out these two posts on the EEVblog forum about my scope. You will see where my current avatar came from.

Great story, and great restoration.
Nice to see you always learning somthing cool
Thanks and thanks for watching.
Hi from a new subscriber in England, I'm enjoying the videos very much. As an engineer and designer inefficiency and the occasional period of procrastination cost me dearly, so your videos such as this one I think are going to improve the productivity within my workshop and business.
I especially like the time efficiency talk at the end, I can connect with you on these thoughts.
Thanks for the video. Stunning good information. Turned to my own backstop for Collets today. It works amazingly well. Looking forward to seeing more of your tricks and tips. :-)
Thanks and thanks for watching.
Wow....that method for the adjustable chuck stop is the answer to a maiden's prayer and I think it solves the problem of variable distances required for thin or thick pieces you want to face etc.
Specifically, it is the 5C collet in the spindle bore......most lathes have a Morse taper in the spindle and can't retrofit a 5C collet without a completely new bolt on 5C closer due to the draw tube diam etc, so many people just make a Morse taper bung to fit in the bore and some form of screw out stop.............been down that path etc......but having the 5C collet to hold the shank of a stop is the answer to the problem even on a lathe with a 3 or 4 Morse taper etc..........all it needs is a Morse collet or a Morse bung that is split etc and a draw bar at the end to pull the Morse taper collet in as you have it with the 5 C method.
Thank you a ton .....now I'll make one as per, but different, to suit my lathe......I prefer the KISS approach and as most lathes already have a Morse taper spindle.....doing as I suggested will make it happen.
The actual inserts that do the stopping can be of different diams as the need for bigger or smaller discs that need facing arises.
But....I got extremely lazy and did it the easy way that I learned as an apprentice.......I took the chuck off, laid it on the bench, mounted the disc in the jaws and then used an indicator resting on the now horizontal chuck face to indicate the under face of the work piece.....this is the way they taught me to do the job as the parts I worked on had to be perfectly flat on both faces and true to each other......some were not round but square.
Awesome a ROBRENZ video! and a regular video announcement!!

Nice to have some vindication for my own feeling that if you are going to do anything more than a few times, you really need to look for ways to make it efficient. Compare tool change time to workpiece change time; make jigs; make specialized tools. Anything that saves a few seconds or minutes, when repeated many times makes a big difference.
Now to go back and watch all your past videos from the beginning. In addition to content, I can always use good examples to make my own videos better.
When looking for a word, Roget's Thesaurus is your friend. From section 74.12 Miscellany: miscellanea, assortment, variety, medley, conglomerate, conglomeration, omnium-gatherum, sundries, oddments, odds and ends. Combine with your favorite time-related adjective* and you've got a name for your series. I picked Erratic Gallimaufry** for my own series (a series with only one instance so far) of the same sort.
==============
* See RT Class One: Abstract Relations, Group VI: Time, Section E: Recurrent Time, sections 135: Frequency, 136: Infrequency, and 137: Regularity of Recurrence

(Does anyone else put footnotes in a comment?)
Thanks Peter for all the input and thanks for watching and commenting!
Hi Robin, just going back through and watching some of your older videos. Obviously time marches on an plans change, but it would be great to see more of you on RUclips. I was also thinking that “Robin’s Roundup” would be a good name for an odds and ends video. Thanks for providing such excellent instruction. Cheers, Al
I'm glad Tom put your link in his video.
Thanks Douglas and thanks for watching and commenting!
thanks Robin, nice to see you. I'll be looking forward to a mech. engineering video. I work on large diesel engines, many forces to consider that aren't always readily apparent. thanks for sharing, take care
Thanks and thanks for watching.
"High Polish Parallax". As in how you can approach things from different angles and different angles of view based on observations. And your tooling looks to be nicely polished.
Thanks 974leoTHElion and thanks for watching and commenting!
Lapping threads for smooth engagement, great tip, thank you!
Awesome video Robin! Been waiting for your next installment. Thank you.

Happy to see that you are back! You are in the top 3 of my favorite RUclips machinists, I really like the attention to detail, same way I like the work of Stefan Gotteswinter. I like Aboms channel a lot too, but that is more of the big and heavy stuff. Just to make the comparison :) Keep up the good work!
Thanks and thanks for watching.
Welcome back ROBRENZ, you have been sorely missed!
A suggestion for your regular bulletin is Bits and Pieces. Or Odds and Ends. Or even Bits and Bobs. OK I know that's three suggestions, but the cost is the same.
Thanks and thanks for watching.
Rob, thank you. I loved this video particularly. Although all your vids are great, this one helps immensely. Great info and great detail. Cheers, Daniel.
Thanks and thanks for watching.
I am new to your channel and I do like what I see a lot. I really do like to see the proper accurate machining you do, great job!
Thanks and thanks for watching
Thanks so much for this video and the other 5 or 6 I just binge watched! Your videos are super informative and hugely entertaining. Thanks!!
Thanks and thanks for watching and commenting.
Glad your back, always of interest...
Thanks and thanks for watching.
Great videos. Love this group of youtube channels you guys all associate together. Found you thru Monday night Meatloaf. Your point about efficiency and time everyone should take to heart. I also like that you mention a tumbler from Harbor Freight and Salvage - relates to my level of hobby investment in this machining interest. After Monday meatloaf it is always a good idea to get a dose of Rational Rigor - you do make it look worthwhile! So that's my title suggestion, even if people have to look it up... thanks Robin!
Thanks kwasg3 and thanks for watching and commenting!
great video, very well produced. Thanks for your time and effort in putting it together. All the best mat
Thanks and thanks for watching.
Thanks and thanks for watching and commenting!
Glad to see you again! We've missed you!
Thanks bucketsort and thanks for watching and commenting!
Good to see you back, figured you must have been busy. Hope you had a good holiday season, all the best for a happy, healthy and prosperous 2017.
Thanks and same to you. Thanks for watching.
another great video. If I was 20 again I would be asking for an apprenticeship in your shop.
Thanks and thanks for watching.
Interesting Robin...
Knowing that the application of jaw pressure outside of the neutral axis has this
effect could actually be useful as a technique for deliberately making a concave surface like that !!
I also really like the trick of pre-setting the stop heights before installation to minimise adjustments on the lathe... 😏
