I am "robinrenzetti" Instagram lots more content there!
Rob says "... plus or minus a tenth - nothing crazy." LOL! Maybe not for you! Great video.
That stuck me too... "Nothing crazy"??!?
Easy with awesome machines and measuring tools. Thanks and thanks for watching and commenting!
@@ROBRENZRob, don’t minimize the talent you add to the equation..😮
Just a quick setup... Based on a lifetime of watching and learning and paying attention! Very nice, Robin!
Thanks Bob and thanks for watching and commenting!
Tool maker for 15 years. Just learned something new and really interesting. Nice work.
Thanks btullis99 and thanks for watching and commenting!
That may be the best thumbs up to thumbs down ratio I've ever seen on a video (1102:1). You're obviously very skilled and knowledgeable, and I love learning from people like you. Thank you!
Thanks At for your kind words and thanks for watching and commenting!
This was awesome thankyou. These types of discussions are hard to find for young guys running old machines, really appreciate the effort!
Glad you enjoyed it!
This is a good example of thinking outside the box for problem solving Thanks
Thanks Jacques and thanks for watching and commenting!
Not only are you a true craftsman, but you're one hell of a smart man Robin. Though I'm unlikely to ever encounter this situation or use your solution I can and certainly do appreciate how you went about this. Great video, a joy to watch and learn.
Thanks for the kind words Moe and thanks for watching and commenting!
Very elegant setup there, Robin.
While we have a centerless grinding setup at work for the surface grinder, it would not have been able to do the job you showed, as it has a pressure roller from the top.
Thank you for sharing! :)
I have heard somewhere that in europe there are many more small centerless grinding devices than is USA I want to find out more about them...... Right now I cannot visualize a topside pressure roller setup....was the unit in your shop a shopmade prototype or a commercialy produced unit ?
Thanks Stefan, I have making that style of centerless unit on my list because it is also very handy. Thanks for watching and commenting!

excelente!
that's german for 'excellent!'
please explain 'induction hardened with tig' that really perked my ears up.
I am not sure about your german ;)
Da Zweifel ich auch (said the Ami)
I am pretty sure all german words are at least 50 characters long.
Thanks Tony, glad you stopped by. I am not sure about your linguistics but your videos are awesome! I did say "sort of" induction hardening with the TIG. I used induction implying a surface only hardening. Obviously the only induction involved is in the saturable reactor transformer in my old school Tig machine. I will do a follow up video but it is just heating the surface with the tig to bright red while trying to not actually melt it. The cooler base metal chills the A2 fast enough to get glass hard. Thanks for watching and commenting.
gotcha. You gave me visions of wrapping the steel in 4-5 turns of tig torch wire! looking forward to your next vid. Thanks again.
Two things you mentioned that I would like to know more about. 1) Tig induction hardening 2) Roundness measurement. Every video you do makes me want to learn more. Your knowledge is boundless....many thanks for sharing it with us all.
This is not induction hardening as there is no coil. It is electric arc hardening.
I still would like to know more about it.

Hey Robin,
That grinding fixture is awesome. Quite obviously, necessity is the mother of invention. As always, lots of little tips throughout the video, even the tubing to drive is quite simple but not so easy to think about.
Thanks for the video,
Alex
Hey Alex, thanks and thanks for stopping in!ATB, Robin

thank you rob
I agree Doug. Thanks for watching and commenting!
Robin, I have few words here - awesome. Many thanks for sharing your vast experience and skills. Kindest regards. Joe.
Thanks Joe and thanks for watching and commenting!
Alot of people think centerless grinding is like voodoo... Not so much. Thanks for an enlightening discussion of methods!
Wonderful solution. This is an example of first rate engineering plus some street smarts (the superglue).
Keep up the outstanding work.

Thanks CobraBuilder and thanks for watching and commenting!
Phenomenal video, I'm filing that away for later. Perfect amount of detail and explanation, too. Thanks for sharing!
Thanks onewheeler and thanks for watching and commenting!
How have I missed this channel? I think I found what I’m gonna binge watch over the rest of the holiday.
I love it when I watch a short video like that and learn a whole lot of things I didn't know. Thanks for sharing.
Thanks, and thanks for watching and commenting!
That was great work taking nothing like a block of steel and making something that works and gets the job done. That was a very good finish.
Thanks Mark and thanks for watching and commenting!
Awesome! Keeping my ears open for things I can do with my surface grinder
Thanks JBFromOZ and thanks for watching and commenting!
Like Quinn says, you are "not of this world".
Incredible content. Thank you so much for sharing what goes on in your head. It's a treat.
I found your page through a recommendation by Stefan Gotteswinter on his channel. Wow, was I glad he directed us towards your channel. I am very impressed with your way of explaining your ideas and thoughts. I am sure I will be able to learn much from your videos. Thank You.
Thanks Shawn and thanks for watching and commenting!
Love your vids Robin. I'm going to need more. Your machinist power level is over 9000...
Thanks TheAlfieobanz and thanks for watching and commenting!
Thank you so much for this fantastic video! I'm in the middle of rewiring a Reid 6x12, and now I can demonstrate to my boss that I can create not only precise flat, but also cylindrical surfaces! I love learning from your videos, they are all amazing!
Thanks bvukovar and thanks for watching and commenting!
Really cool, as always learned a lot! I also like how you seem to approach parts from perhaps a different perspective than other machinists on UA-cam, strength through diversity!
Killer dude! Super simple set up and fixture. Fixturing master right here.
Thanks AHM5 and thanks for watching and commenting!
Great idea Robin. I have been looking for used cylindrical grinders, but your fixtures are better. You are a master.
Thanks John and thanks for watching and commenting!
Thanks for the excellent video Robin
Brilliant, elegant, simple, effective.
Thanks The Trevor and thanks for watching and commenting!
Outstanding! I love the fact that you adopted such a simple, yet complex, engineering solution to reduce all that potential labor. This is the kind of problem, ideation exercise and solution mapping result that should be experienced by engineering students and skilled trades folks alike as they develop. The results speak for themselves....so my hat goes off to you Sir for a well thought out experience based risk taking exercise! Congrats on getting things out the door correctly faster by adopting a more optimal approach.
Thanks for the very kind words and glad you are enjoying the content.
Great videos, like others have said , I needed to find your videos back when there was no you tube! Keep up the great work !!!! Thanks
Simple, ingenious and interesting... I'm still trying to wrap my head around the required angles (offsets) to get round parts and why. Fascinating problem solving and "shoe center less", didn't even know that existed... but hey... I got you as a teacher... thank you for sharing... great video... very useful topic!
Thanks Frank and thanks for watching and commenting!
That's very interesting. I'm always looking for ways to be more creative with my equipment. This video adds to the tool box.
Thanks for this! You Da Man!
Thanks for doing this video, I was not aware of what centerless grinding was exactly. I appreciate it.
I love your mind and problem solving skills ! Really good job on all your videos . Been a subscriber for about 6 months now and definitely impressed
Thanks nathanael and thanks for watching and commenting!
Excellent solution to a difficult problem
Great little note..opened up some possibilities for me in my tiny shop. Just the right level of explanation for me. Quick and concise.
Brilliant. A very clever solution to a seemingly impossible problem. You nailed it perfectly. Thanks Robin.
Really nice.....
Thanks for sharing this little great trick, and taking the time to make the video and share
What a genius idea!,,thanks for sharing this method!!.
Elegant, brilliant, effective, etc. (as usual). Thanks for sharing.

Thanks, and thanks for watching and commenting.
Incredible. Love this next-level stuff, Rob!
Thanks Brad and thanks for watching and commenting!
Love the problem solving aspect of this. Thank you
Thanks slausonm and thanks for watching and commenting!
It's a great idea,
I loved it enjoyed every detail discussed about it...
I'll try and make one to check,
I do grinding some of my jobs with v blocks attachment I've made for my needs....
Another great vid, love your thought process, and clear, concise demo. Thanks!
Thanks Michael and thanks for watching and commenting!
Brilliant. Thanks for sharing! - Watchmaker from Australia.
Very nice idea! Congratulations.
Thanks Nilton and thanks for watching and commenting!
Genius, intelligence is develop a simple solution for a repetitive task, thanks for sharing your knowledge.
Thanks Isidoro for the very kind words and thanks for watching and commenting!
Clever dude. I got lots of set-up fans run time on centerlesses and I've been Dow the road with lobed parts so I can appreciate your adaptation and explanation..
Never heard is the "shoe" trick but I admired your application.
Thanks Forrest, take a walk through a ball bearing plant and you will see hundreds of shoe centerless setups doing races. Thanks for watching and commenting!
Such a simple but great & efficient idea.. cool
Absolutely a great segment, I am so glad Tom brought you to light for me.
Thanks Douglas and thanks for watching and commenting!
Wish I found your channel years ago. This is what machining and industry is missing. Genuine ingenuity to solve a problem with the tools on hand. I look forward to watching the rest of your videos
very clever idea Robin
Thanks for sharing this technique Robin. Yourself and Edge precision are my favorite UA-cam channels for exactly this kind of content!
I agree, 2 humble guys with incredible knowledge as opposed to the usual "egos, bravado & hype" types.
hahaha Dressing the centerless regulating wheel is the stinkiest job in the shop! Found your channel through Tom Lipton's channel and I'm already liking your content. Great video, it was very well thought out and put together!
Thanks Austin and thanks for watching and commenting!
Nice! I was thinking of rigging up a center grinder setup for my tool and cutter grinder. Now I have a better idea I think I'll go with the shoe style for my first try. This was a very informative video, Thank you!
Thanks and thanks for watching and commenting!
What fantastic out of the box thinking Robin!
Thanks Ken and thanks for watching and commenting!
I always wondered how centerless grinding worked. Thank you.
You are welcome Scott and thanks for watching and commenting!
great real world solution! Love the idea and the video. Thanks
Thanks Robert and thanks for watching and commenting!
This work holding and being able to grind like this an a regular grinder is very cool!! Great engineering here Robin! Thanks for sharing very motivating for me.
Glad you like it!
I’d recommend any engineering major get a machining cert as well, especially mechanical engineering, idk maybe it’s just me but it has served me well on personal projects.
looking forward to the think like and engineer video. interesting intro to centerless grinding. now keen to see more.
thanks Will
Thanks Will and thanks for watching and commenting!
As a retired Tool / Mold Maker I definitely appreciate the time you’ve taken to make these videos I’ve learned a few things from you and have a few things I would be happy to share. Keep up the great work👍👍🤙
Please share, I learn something new every day.
Hey Robin, luv watching you guys achieving such tight tolerances.
Thanks Denny and thanks for watching and commenting!
Brilliant and clever as usual Sir.
Thanks fun one and thanks for watching and commenting!
You are one of the most capable individuals I know of. Thank you for sharing your insights.
Thanks for the kind words Kelley and thanks for watching and commenting.
👍 watching this for the umteenth time. This sort of content is so valuable. Thanks again for sharing!
A whole lot in this I hadn't known about centerless grinding rests and a more than clever solution to not having a centerless grinder to make things easier Robin. I'm not sure a full build video for the part rest would be needed anyway. It's already pretty clear what's there.
Thanks Turning Point and thanks for watching and commenting!
Hi Robin,
I worked on many types of grinding m/cs including centerless & surface grinders in Coventry in the U.K, was amazed never seen any thing like it, great videos.
Thanks, and thanks for watching and commenting.
Very cool fixture that you have come up with.
Thanks Robin that was very good. Much appreciated.
Thanks and thanks for watching and commenting!
Before this video, I had no idea what centerless grinding was.... Great solution....! Keep'em coming....
Thanks and thanks for watching and commenting.
very nice. it's a pleasure to learn about grinders. I don't have a lot of experience with them so I don't get everything out of mine that I should. I appreciate you sharing your experience.
Thanks Leaf and thanks for watching and commenting!
Such a wonderful channel.
Very nice setup. Great information.
Thanks and thanks for watching and commenting!
really enjoyed the problem solving - very cool!
Thanks bo and thanks for watching and commenting!
I love watching your videos.
Its the way you think and approach and solve problems based around *fundamental principles.*
I keep telling other engineers that we are forgetting our fundamentals and relying on technology too much. Where its most obvious is in problem solving. The entire Max-8 fiasco was problem solving exercise where they just forgot some very basic fundamentals about sensors and control systems like the very basic fact that sensors can fail.
Just brilliant Rob.
Alan.
Thanks Alan and thanks for watching and commenting!
Great video and good idea on grinding those little parts keep the video's coming!!
Thanks Loren and thanks for watching and commenting!
awesome stuff Robin, thanks! nice to see you. be safe.
Thanks 682 70 and thanks for watching and commenting!
Good idea. I would have used a setup like this 2 or 3 times in the last year. It actually inspires me to make somthing that will attach to the table of my od grinder.
I hope you keep making shop videos. Its nice to see someone that puts the thought and efforts towards the finest level of precision possible.
Thanks Mark and thanks for watching and commenting!
