Retaining Ring - I had lost one for another item and sort of figured I was in trouble. Then I thought of a SPRING. Went to the spring junk drawer and found one that was very close to the right size. I cut off a loop then enough for the opening and it is working great.
That design is what some would call "'elegant." It's an interestingly simple yet clever design. Thank you for the tour.
Thanks Mr, Pete! The Noga arm is so taken for granted these days that most other machinist channels on UA-cam don't bother showing how it works. I've been wondering for ages. Great explanation!
Thank goodness you were able to uncircumcise the thing and get it back to being a fully working member.... I think it's too late for me and mine though. I have to say, you did "Just Right!" Not over explained or under explained. I did enjoy learning how they work after all the years of using them.
we would have been happier if Noga has some respect for your great channel that exists much before some other that receive entire kit from them. And thanks for that demo that let us understand how it works.
Just pointing out that even the Noga arms are imports. They are made in Israel. Of course most people(myself included) think China when we say import. Enjoyed the video. Thanks as always mrpete.
The original inventor was Carlo Baitella, patented in 1973 as CH549260A and 1975 as US3910538A - "Jointed stand for dial gages" - and founded the company FISSO which still makes them for both machining and medical applications. Noga, Bogen, Manfrotto etc. are all copies of that original design (now that the patent has expired).
Thank you, very interesting. I will look up those patents.
Lyle you have a down to earth ability to get the message across.
Don't under estimate your unique ability as it always keeps me interested.
The variety of topics ( from rust treatments to machines) really makes your videos.
Not forgetting the road trips and auctions completes the picture for me.
Cheers from down under and please keep up the great work.
Lyle, I agree with Greg. Don't worry about possibly over-explaining things. Many watch your Channel in order to learn these things and don't otherwise have a way to (easily) learn them without your explanations. The "experienced" Machinists probably either watch these teaching videos anyway because they know they don't already know _everything_ or skip to your machining videos, et al.
Thanks for watching
Ahhh, Finally, I have been waiting anxiously for this one since you announced that you would be doing it. You nailed it, thank you!
Mr Pete, your explanation and illustration of the articulating arm was quite clear and informative. Thanks for posting, I learned something new from you (again).
Wow! It's s such a simple mechanism. Whoever invented this was incredibly clever. It's a fantastic design.
Many thanks Mr Pete! I agree, it is so simple yet very clever. I recently took apart an articulated camera mount that uses 1/2 of the same mechanism and never realized it works the same way as the Noga. The camera mount is just a single ball with no arms, but it uses exactly the same wedge to tighten the ball. Then Noga (or whoever developed their mechanism) came along and realized that they could put two of the wedges back to back and move the balls out using hollow arms. Pure genius! Again, thank you so much for making this video. I really enjoyed seeing it. -- Mike Litzkow
As usual another great video, great way to start a Saturday . I have a very nice Noga and I sure wondered what makes it tick. For what it cost, I wasn't about to take it apart. Thanks very much for showing how it works and taking it apart. I never imagined that it works the way it does. My three functional brain cells weren't able to comprehend how that thing worked, so I thought it might be best to leave it alone. Then along comes Mr. Pete and explains it all. Thanks again for another great video....Ken
I've been wondering how these arms work and have been eagerly anticipating this video since you mentioned in the mag base video that it was in the works. Thanks for following through.
Simple but yet effective.
Thank you Me Pete.
Thanks for the very thorough explanation of how these work. I have wondered ever since I got them but wasn't brave enough to take one apart.
Lonnie
Thanks for the video Mr. Pete. Very nice explanation on the inner workings of this type of indicator arm. As always a pleasure to learn something new from a favorite teacher.
Thanks, Lyle. I have wondered how they work for a long time. Now I know. You are great!
Good video, thanks for sharing. As an auto-truck-heavy equipment mechanic I used one of the CentralTool version for many yrs checking crankshaft enclosure, diff and axle play, rotor and flywheel runout, ect. Yes it has inherent play issues but the tolerances I was working with were multiple thousands. For engine building ect I used a properly secured base to measure from. The problem is in automotive work it's difficult to find an area of steel large enough to mount a magnetic base although over the years I've built a number of Rube-Goldberg setups to put a flat of steel in odd places.
Thanks to you and Mike for this video. So simple yet brilliant, then again so many are, one of those"why didn't I think of it". Thanks Peter
Makes complete sense now that the secret is exposed! Thanks Mr Pete (and thanks to Mike also) for another enjoyable and informative video! Best wishes from down under.
Thanks again Mr Pete for all your help understanding the universe. Clever simple ideas that I never would have thought of. Keep up the good work.
And again thanks to you I learn something about an every day tool, THANK YOU MR Pete !! MArk
I had an idea about it and when you removed the ball end you confirmed what I had thought was how they worked. I still use the rods but now I'm thinking about getting an articulated arm or two, thanks for the video on it!
VERY nice design (smart, simple, works every time) and a very good explanation! Thank you Mr. Pete!
Great video! I have often wondered how those things work! Thanks for all the shop classes!
Very well explained, thank you. I have one of these cheap imports that's just got more and more seized up, so a search on how to take these to bits, and lo and behold it's my favourite UA-cam shop teacher! thanks again Mr Pete.
Glad it helped
Thank you Mr. Pete! Excellent explanation of such a useful tool. But come on, the Popeil pocket fisherman was just as genius as the Noga articulated arm! 😂😂😂
A well articulated instructional presentation!
So glad you did this video. I have always sort of vaguely been wondering how these worked and finally sat down to find out. This video was extremely clear and right to the point. Thanks
Thanks
Thanks for showing us how these things work.
Very interesting.
Was watching Quinn's video (over at Blondihacks) on making a DSLR adapter for the Noga holder, and it got me thinking: how can a dial indicator holder hold something that heavy?
Searched UA-cam and found Adam's review on Noga holders. Unfortunately he didn't show how they worked.
And then I found this!
Thank you, Mr. Shop Teacher!
👍👍
Hey, Mr. Pete! Another nice video. I wouldn't worry about whether you're over or under explaining things. Just do your thing.
Thanks for watching
Great video a coworker and I were just wondering how these worked today, ingenious and simple design, awesome.
Surprisingly simple, thanks Mr Pete!
So intelligent and simple solution. Very clever people invented this....
I for one simply enjoy your teaching style. As Tom Lipton is apt to say "nothing too strong ever broke". There can never be too much information being taught by actual expert craftsmen. Knowledge is the key to a successful life,which come from the teacher to the student,passing the baton to the future,a wink&nod from the past.
Joseph Wilson Well put
Good stuff. I was sure it worked with a cam mechanism, but this is not what I had envisioned. Simple, and yet effective.
I wondered about the mechanism for locking three joints at once. Thanks for the video.
Simple but, very clever. No wonder there are so many knock-offs. Thanks for sharing, Mr. Pete.
Really appreciate your videos. I've wondered about how those things worked also. The plunger is small, but it's also pushing against that ring that has a diameter almost as large as the ball.
Interesting and informative. Well done and congratulations on receiving a fine gift to add to your indicators.
Class 5 Beverage Alert at 8:00 I almost lost some spaghetti in the sinus cavity.....
Good clear explanation. Thank you!!
LOL me too ........makes it extra funny when you consider it's an Israeli made product
You saved me the trouble of taking one apart myself out of curiosity. Thanks!
Thanks tubalcain, love this series so much :D ♡
I always wondered how those work. Thanks for the explanation.
Good explanation. I always wondered how they worked.
Awesome and looks like be a fun shop project . Thank you !
Excellent, thank you. I have a couple on which I will remove the large knob and put a touch of grease on the tapered portions.
I bought that exact indicator holder about two weeks ago. Works pretty well. Mine isn't as flexible when it's loosened but it is relatively rigid when it's tight.
Super clear explanation. What a great idea!
13:00 Really smart, thanks for uploading, nice info.
Great video, I was looking forward to seeing how those arms worked. Like another commenter bendavanza, I own a Manfrotto "Magic Arm" for my camera which I guess works in the same way. In fact there are two types of Manfrotto Magic arm, one with a knob that is turned to lock the arm and another type with a lever. The lever mechanism sometimes gets out of position and you have to disassemble it and reposition a half-dozen ball bearings. I guess the rotary-knob version is better. I always wondered about the mechanism for locking three joints at once. Thanks for solving that mystery.
Well done Lyle!! It really is a simple design, however the Noga is probably a little different in types of material used etc. Thanks for the vid and keep this type coming!
Thank you mrpete222 for demonstrating such a nice and mind-blowing video. Great and caps off.
👍👍
HI MR. PETE, YOU ARE A GREAT !!!!! INSPIRATION TO MANY OF US !!!! THANKS SO MUCH . JOE OUT IN S. JERSEY.
Thanks Mr Pete, I have one like that and have often wondered how it worked.
Very clear and informative. Thank you.
Very good explanation. Thanks so much!
Brilliant explanation, thank you once again.
Own a Noga articulated arm. Never been brave enough to take it apart
I always wondered how those worked, I have the automotive one like you have Mr. Pete, as a Mechanic, I curse the thing daily, I love the Vicegrip part of it. But trying to use the old style rod type is more of a pain, but it at least doesn't move if a mouse farts a hundred yards away, while trying to measure runout on something, unlike the old ball and sleeve type with the cable in it. Thanks again for another great video and explanation.
Thanks, I've seen Abom79 use one of these a few times and I was curious how the one knob locked all of the joints, very well done sir.
Noga came up with a brilliant design. I just bought a new noga with an odd looking permanent magnet to mount on the tool post for lathe work. The magnet is about 3/4" wide x 3" long. it's very strong for it's size, but easily removed by tipping it sideways. The only thing that I don't like about this new Noga is it only has a dovetail mount. No means of clamping the round bar on Swiss style test indicators. I haven't looked yet but Noga probably sells an adaptor.....Being the Greedy Devils that they are. : )
Thanks Tubalcain! I wondered how they worked, but never wanted to take one apart to find out. I would have lost the clip!
Hey Lyle, you mention the end of the shaft is rather small but it's purpose is to push the ball against the retaining ring where yes, the actual contact area is maybe smaller but spread over a much larger radius. Love your vids by the way. Thanks for making them.
Yes we are now understanding, thank you.
thanks for the video, a while ago I could only find diagrams and patents when I was trying to figure out how these worked :)
Always wondered how they work - now I know. Thanks Mr. Pete.
👍
The rod pushing the ball doesn't need to resist the ball turning. It simply pushes the ball against the retaining ring you took out. Creating enough friction to immobilize that ball. To some degree, it's a combination of the two I suspect.
Thank You Sir for every bit of info that You have shared with the world .
My pleasure
GREAT JOB !! MR. PETE EXPLAINED VERY VERY WELL YOUR ARE A VERY SMART MAN JOE
Thanks
Ahhhhh... The Pocket Fisherman.... Best thing around for putting ham radio antennas up into trees!
lol
You did a great job explaining this !!
Thanks for watching
cant wait for the next one!
At first glance I kinda figured there was some kind of rod in there pressin the balls. Where I veered off is with the middle joint. Me being a gear head, thought there would of been a cam lobe in there instead of a simple wedge.... I guess that's where K.I.S.S. comes into play. Great video, thank you Mr. Pete!
What a fantastic explatanion profesor!!!! thanks a lot!!!!
The Swiss apparently make ones that work hydraulically.
Of course they are completely un-affordable, being from Switzerland and all.
The one you use for the camera that locks up hard, that actually looks like the hydraulic ones.
Have a look at US 3910538 A and the links at the end of that one. There are countless patents for this type of arm.
Now I think this type of articulated indicator arm will be one of mine upcoming projects - How to make an articulated indicator arm. Nice video - as always.
@Tony Wilson No need to do so. I made one 2 years ago.
@Tony Wilson I had not looked at any of the channels you suggested when I made mine so it was probably my own version I made, but similar to the ones you can buy.
@Tony Wilson Thank you!
@Tony Wilson Sweden and we are all doing well thank you. Stay safe.
Great video, very informative and easy to follow, thanks!
Thanks
I really enjoy this series. It seems there is hardly a week that goes by that I need to tear something apart to repair it and there is always that bit of discovery before the repair. Sometimes I say aloud (no one listening in my shop) "what insane idiot designed this piece of excrement?" And then there are other times when I say, "I could have thought of that, but I didn't, great idea." I would say the second on this device. As you began I had all sorts of ideas including a rack and pinon setup (what a piece of excrement that idea would be). Great video Mr. Pete.
You explained this perfectly. Thank you.
Thanks
A truly elegant design: that is, simple and obvious when you take it apart and look at it BUT not so simple when you start with no previous information and a blank piece of paper.
Great Video Mr Pete, very informative.
👍👍
And again thanks to you , i really appreciate this information ,,
Was thinking of machining a few new parts for one of these cheap Chinese knock offs and appreciate the disassembly video. Think I'll break down the portion that holds the dial indicator as well.
Thank you very much Mr. Pete.
👍
It's like a dead animal when it's loose. Nope, you are not overdoing or overexplaining anything. I like it. Take the knob off of that other style holder that you said you liked so much (your favorite) and you'll probably find another square nut spacer. It's a mystery. Some day we are going to have to have the surface area and holding friction talk and I know everyone is going to get upset about it, but it really is what it is. Size (or area) does not matter.
What did that guy just comment!!! Size doesn't matter?? Blasphemy, it's blasphemy I tell you. Don't listen to him! Cover your ears! ......... Yep, frictional forces are NOT a function of area for sliding solid to solid contact surfaces, area is not even in the equation for drag. (so, what about birds, boats and airplane wings? Not solid to solid.)
Nice to see how this thing works... thanks
Thanks
this was interesting. Looking forward for a "making an articulated arm" now... :)
I've got an identical looking import on the way from China or somewhere . Thanks for showing us how it works. When it comes in I can use it, improve it, or dump it.
Another of life's mysteries explained. Thanks.
Thank you for demonstrating the action inside the arm. I don't have a Noga either but I do have a "magic Arm" from Bogen Manfrotto. I am sure it was made by Noga under license. It is as you mentioned a photography item and it is quite large, the arms are around 1" in diameter. it's action is much smoother and more secure than the knock off indicator. I imagine a little polishing to the wedge faces of the cheapo unit would improve the action.

Thanks for watching
ua-cam.com/video/qnHfHl7LI7Y/v-deo.html
very helpful video for me... thank you for making me to understand the concept of it
.
👍
very interesting i enjoyed it thank you mr pete
I have one of the first units you showed, and it cost me around 10 to 20 dollars, and that was the best that I have. But I saw one like the second one you showed, and for about 40 dollars, and I've never been so disappointed in a tool, as I have been with that one. It's not even good enough to hold a camera. The problem that I saw was, that after you get it where you want it, and tighten it up, you just watch it for a bit, and you can see it move around on its own, without even touching it. This will make a very good garage sale item for around 25 cents. That might even bee too much!!!
I enjoyed the rest of the demo.
Have a good day!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Michael
GREAT VIDEO !!
Thanks, very interesting.
It looks so easy, even Simple enough to build maybe one in big ... next project mrpete... :D
Great video
Pocket fisherman , good one mr.pete !! I remember those , fortunately I never had one 😎
