Mr. Pete saves the day again. I just purchased one of these items and couldn't understand the pidgin english instructions included with the indicator. And I quote: "The centering indicator is designed as a precision measuring instrument for locating a workpiece by the pointer while the spindle rotates when the spindle rotates, the indicator always face the operator. Thus brouoht much convenience for operator." We also have other classics such as: "Place appropriate feeler in indicator rocker braecker and screw it." (Holy smokes!) and "The strajoht feeler is for use in inside diameter measurement." Anyway, thank you for providing some clarity on how to properly use the device.
I have one as well. Never have I had anyone elaborate as well as you have on correctly using it. Thank you for taking the time to make this video. It helped me a lot instead of trying to interpret the folded up 4" x 4" paper inside the case.
Not only should you run it slower as others have said, but I also put the spindle in neutral and walk the coax around by hand to make finer adjustments. 12 and 6 o'clock and 3 and 9 will get you centered pretty well.
I watched all of your videos years ago, most of them more than once... Years later I still find myself coming back to your videos for refresher courses.
I have never run a mill, but i'm researching coax indicators, and ended up here. When adjusting the X,Y in the last stage, you set the X, first, to a needle moving 0.005-0.006, trying to see a change. Then you adjusted the Y, seeking zero deflection. Wouldn't you want to go back, and see if a fine adjustment on X, would bring the needle to zero? It seems it would be easy, and quick to do. The Y axis looked much easier to adjust, because you were approacing zero; not so with the X, as the gage was going all over the place. Thanks for sharing your knowledge... and for all the work it takes to make these vids. You and I were around the last great days of public school. I taught in the '70's & '80's, (did a couple of 'stretches'). TH-cam, in a lot of ways is a portion of the modern school. Google, and research, TH-cam to see practical, safety, and industrial use, then the how to's, on top. (I watched an industrial safety film about abrasive stones a few years ago, and it turned me off bench grinders, every since. lol, I use abrasive wheels only on the bench, now.) Later
Need to use low range! I wouldn't expect that indicator to last long with that needle flopping half way around the dial 10 times a second. Just my opinion though.
Thanks Mr. Pete. I have the same indicator and really like it. It will also tell you if your lathe centers are out of alignment, and turning the lathe over by hand, it will tell you which way it is out.
Christmas came early! I know the snow has dragged on till now - but maybe Santa had one left over for me :-) The video clarifies more than its Instruction sheet - but a great little tool. We had issues centering manually - and the time it takes - this has now double checked our equipment and we are satisfied that all is OK. Many thanks
Hello Mr. Peterson. Once again you have taught me something interesting that I knew nothing about. Good episode, clearly presented, and very useful. Thanks again. Bob
Very cool. You have convinced me that I need one of these. The plan is to use it to set up a rotary table. After that, use it to position work on the rotary table. This is going to be fun.
I use mine when repairing destroyed bearing holes in castings so I'll turn the spindle by hand and indicate only 3/4 of the hole or if it's oval you can center it by allowing for the runout. Great tool.
I received that exact same indicator last week. I can already see it is indispensable for my little Grizzly G1007 mill/drill. Much more so than the hallowed Bridgeport. Every time I change tools the next tool is either too long or too short to reach the part and I have to move the head and realign since I have a round column. Thanks for the video.
Thanks for this. I have seen so many people using a co-ax by hand turning the spindle. It sort of takes the point out of using a co-ax. You get the forward facing dial, but everything else is no easier than using a conventional indicator.
awesome video, I just seen one of these in the machoinse shop i started at 2 weeks ago, seen one for the first time yesterday and wanted to look up how to use it again, to firm up the idea in my head. thanks so much great explanation
Hi mrpete, This is a great demo, very clear explanation, now, just have to think about using mine more often... If I remember, the little screw holding the feelers is stripped due to lesser quality fabrication, can't have it all... Thanks, Pierre
I have bought one of these indicators "new" & haven't used it yet being not very educated on how to use it properly. Thanks for the video it really helped! But I would not run it that fast there is no need to. Another good use for it is to realign the tailstock quill on your lathe after moving it for turning a taper, it will at least be a ballpark start for a more accurate alignment. Cheers - Pedro...
Tubalcain I know you are old, but in the last two videos I watched you made grim references about your life expectancy. Time is precious my friend, don't waste it thinking about how much you have left.
I really enjoy your content. There’s another creator that I really enjoyed. It’s very popular that has issues with his milling machine would be really cool if you could do something with him mats off-road recovery.
well he cant go slower the indicator can not be spun faster than 700 rpm and his mill only goes as low as 644 rpm so he is already as slow as he can go.
@@slader-hl1kk If its a Bridgeport then the speed can go much lower than 644 rpm I have a turret mill similar to the Bridgeport but mine is an Elliot and it can go down to 40 rpm!!!
Starting with X and then Y makes sense, but I might go through that process twice. When you adjusted X it was so far out, I imagine that you didn't get X dead nuts. Once X was close, Y looked easy, but I would have gone through once more to be exact.
Thanks for the demo on using it. I do wish they would make a little more compact version of the co-ax indicator. I do not have a knee my bench mill and adjusting the head up and down to fit the indicator and then back to use collets with a mill would move it out of position.
I bought one too, lol. Shares should give you a kickback Lyle! I'll be getting my combo machine soon, so I am going to order your Bridgeport course, and add a few tools...like this one. Surprising how inexpensive the things are, when you think about it.
By this way of using you are surely reducing the fatigue life of internal mechanical parts of that dial gauge, and thereby reducing its lifespan and it's accuracy......
I just had a look at this video. As everyone has pointed out there is no need to spin it that fast. I turn mine as slow as possible like 100 rpm. it works like a damn.
people that are saying your running the indicator to fast must not have been listening during the video,lol , he said in the beginning the indicator can be used up to 700 rpm and his mill only goes as low as 644 rpm, so he is running it just fine it is rated for that fast. and he cant go any slower so it will be just fine.
Easiest way I do this is swing the indicator around the actual diameter I'm indicating by eye ( off the workpiece ) and move the axis' until it looks close, then drop the indicator on the diameter to be indicated and again move the axis' until it's indicated in. Usually I can get within .020" by eye before sweeping the actual workpiece.
I personally never like to run the machine over 10 RPM. Gets you much better precision. But I work with high precision parts, so I need to be accurate down to .0001 or better. (CNC machines)
mrpete222 Just below and behind the quill lock is a boss with a thumb screw into which you can mount a rod pointing down, ideal for resting the co-axial indicator arm against. I think Adam and Tom amongst others use it to hold a bent rod for a misting style coolant system.
I agree with some of the others. Your spindle speed is far too high for a coaxial indicator. I have been using one for years and years. Run it at about 100rpm. Also, put a little oil where your feeler ball contacts the work piece to keep it from chattering. Especially so on aluminum (and other soft materials) , as the ball will gall the surface, and build up material on the ball, and make it run rough as all get out. Also dont forget to oil the contact face of the indicator body, you will burn up the surface running it dry.
There is. To the right side of the spindle, on the spindle housing. However, it's not for a coaxial indicator. A coaxial indicator is required to spin in order to do its job, and what you're referencing is a casting in the housing, therefore doesn't spin. The casting "hole" is used for holding an indicator to align work in the x and y axis without the need for removing your tooling. Works like a charm for that purpose, but nowadays, so do spindle indicators, which are just attached to the outside of the spindle. Many ways to skin the cat, so to speak.
I'd think you would want to turn the spindle by hand like with the last word so that you can see which needle movement is caused by which axis. In other words use the technique of an ordinary test indicator that has the dial facing the same way all the time.
Galfonz, the instrument is designed to be turned by the mill. In general, that is the way they are used. I suppose one could come up with a reason to turn it by hand if you just had to know how much it was out and/or in which axis. But, I've never indicated something that was only out in a single axis.
Great video TC! Thanks. I didn't know of such an indicator. I know you don't answer questions very often... but I'll try anyway. I notice in Tom Liptons book that he is very thought provoking about Bridgeport as a milling machine. I am wondering about your opinion. I am getting ready to make the plunge to own my own machine and I truly value your thoughts above most. In advance... thank you.
Jeff Conti I have not read that, and I guess you are saying he is critical of BP? I like mine, but I have used & liked INDEX & South bend mills. My brother had Encos & grizzly & likes them.
When you say roughly center the gauge are you talking about eye balling the actual gauge itself or the tip? if its the gauge then how do you know how much to move it in to touch the work piece?
***** I run mine at 270 RPM, which is the slowest my mill will turn. However, I have run it faster now and then. To me, the slower RPM makes it easier to zero it out.
I don't follow how the units could read in thousands. Wouldn't the distance vary by length of the probes? By the way, I look forward to hearing 'So long for now' at the end. I felt something was missing when you didn't.
did you watch the video he said his mill only goes as slow as 644 rpm and the indicator is rated up to 700 rpm so he is using it just fine its within the rated specs.
+Toolmaker are you fucking kidding me? How how the hell could someone they call themselves toolmaker ask if a dial indicator is obsolete that doesn't even make sense
+Clown Whisper I say this because every shop I worked in has had one of these indicators and all it does is sit in the cabinet unused no one ever uses it
+Clown Whisper I always use the last word indicator with a rod extending the indicator to appropriate diameter and so do many other Machinist I'm not saying it's not good instrument I'm just saying I don't see anyone using it
+Toolmaker LOL I I was half asleep and thought you meant the indicators were obsolete indicators in general lol nothing made sense to me I guess I shouldn't remark when I'm half asleep
when first starting out there is always someone that got stuck with getting a coax indicator then they spend the rest of their carreer trying to convince people on it. Not needed in the slightest.
freakboynv2000 coaxial dials need to run as fast as you can turn them by hand so the lowest speed is ample enough anything more is nonsense,wear and tear friction vibration centrifugale force and so on.the speedo on my car says 280 but i never go that fast its pointless. keith fenner has a perfect demo of what im talking about.
So what or who is tubalcain? A last name? Or a username? How did you come up with it. Been watching your videos for awhile and that always baffled me your username is mrpete, but you introduce yourself as tubalcain. Great videos by the way!
For close work such as indicating a work piece in with an indicator, I see no need to engage the spindle. These type indicators have limited use and really just take up space in your tool box. That's just my opinion. Learn to indicate the right way!
Ummm...that's a great way to destroy Your indicator... slower rpm for God's sake or by hand.... I bet running it that fast is giving you that "vibration" and a false indication
First of all you have to realize that in these days there is no room for the words "perfect or perfectly " perhaps in your days there where no good ways of measuring some thing accurately and you could call "perfect or perfectly " at anything within .0001 of an inch but nowadays with the modern measuring ways those words are obsolete.
uummmmmm…. way way to fast. if you don’t want it worn and blown out after 4 parts i’d run it as slow as possible or buy hand… would you run your other dials in a reciprocating fashion that fast 😆
Mr. Pete saves the day again. I just purchased one of these items and couldn't understand the pidgin english instructions included with the indicator. And I quote: "The centering indicator is designed as a precision measuring instrument for locating a workpiece by the pointer while the spindle rotates when the spindle rotates, the indicator always face the operator.

👍👍
My friend that indicator is running too fast you have lots of vibrations on the needle 50 or 100 RPM will be more than enough!!!
in addition it will damage the centering because the pinions of the inductor are too solicited.
@@ozzyozzy626 Ahhhhhh. The smell of solicited inductors in the morning. Thanks for the tip. Mine are now well solicited.
well he cant go slower the indicator can not be spun faster than 700 rpm and his mill only goes as low as 644 rpm so he is already as slow as he can go.
@@slader-hl1kk If its a Bridgeport then the speed can go much lower than 644 rpm I have a turret mill similar to the Bridgeport but mine is an Elliot and it can go down to 40 rpm!!!
Need to run it in low range!! I use a coaxial indicator almost every day and I would never run it that fast, it will ruin it very quickly
Good video-would recommend new users using longer probes and lower RPMs. I use lower RPM on 100x and 10x, then faster RPM on 1x.
Starting with X and then Y makes sense, but I might go through that process twice. When you adjusted X it was so far out, I imagine that you didn't get X dead nuts. Once X was close, Y looked easy, but I would have gone through once more to be exact.

I just had a look at this video. As everyone has pointed out there is no need to spin it that fast. I turn mine as slow as possible like 100 rpm. it works like a damn.
I just purchased one , thanks for the heads up ! 👍👍👍
You should use the slowest rpm so you can see the needle move and that you don't were out your needles.
people that are saying your running the indicator to fast must not have been listening during the video,lol , he said in the beginning the indicator can be used up to 700 rpm and his mill only goes as low as 644 rpm, so he is running it just fine it is rated for that fast. and he cant go any slower so it will be just fine.
Gonna get me one of those, as soon as I get a mill. Might be in a couple years, if I live that long.
Easiest way I do this is swing the indicator around the actual diameter I'm indicating by eye ( off the workpiece ) and move the axis' until it looks close, then drop the indicator on the diameter to be indicated and again move the axis' until it's indicated in.
Usually I can get within .020" by eye before sweeping the actual workpiece.
+Ham Steaks thanks, that's good advice
mrpete222 No problem. Your method would actually be easier for something a little more fussy like when using a .0001" indicator though.
Mine user manual says at max rpm is 100rpm to use this kind measuring tool
I personally never like to run the machine over 10 RPM. Gets you much better precision.
But I work with high precision parts, so I need to be accurate down to .0001 or better. (CNC machines)
Don't forget, there's a place to mount a rod on the right hand side of the head, no need for a mag base.
Paul Compton I do not understand
mrpete222 Just below and behind the quill lock is a boss with a thumb screw into which you can mount a rod pointing down, ideal for resting the co-axial indicator arm against. I think Adam and Tom amongst others use it to hold a bent rod for a misting style coolant system.

I agree with some of the others. Your spindle speed is far too high for a coaxial indicator. I have been using one for years and years. Run it at about 100rpm. Also, put a little oil where your feeler ball contacts the work piece to keep it from chattering. Especially so on aluminum (and other soft materials) , as the ball will gall the surface, and build up material on the ball, and make it run rough as all get out. Also dont forget to oil the contact face of the indicator body, you will burn up the surface running it dry.
you didn't watch the video, he did oil the feeler,
I was told there is a hole in the head of the Bridgeport for a coaxial indicators, so how or why didn’t you use it vice the collets
There is. To the right side of the spindle, on the spindle housing. However, it's not for a coaxial indicator. A coaxial indicator is required to spin in order to do its job, and what you're referencing is a casting in the housing, therefore doesn't spin. The casting "hole" is used for holding an indicator to align work in the x and y axis without the need for removing your tooling. Works like a charm for that purpose, but nowadays, so do spindle indicators, which are just attached to the outside of the spindle. Many ways to skin the cat, so to speak.
I am ready to puke with that co ax running that fast
I'd think you would want to turn the spindle by hand like with the last word so that you can see which needle movement is caused by which axis. In other words use the technique of an ordinary test indicator that has the dial facing the same way all the time.

And I would like to know its price, please
75 bucks right around anyway
Do they make any American made coax indicators
not sure

Why run the spindle so fast? - surely a slower speed will be just as accurate and they're will be less wear on everything?
He wanted to keep the video as short as possible...

did you watch the video he said his mill only goes as slow as 644 rpm and the indicator is rated up to 700 rpm so he is using it just fine its within the rated specs.
As always, thanks’ for taking the time to make this video! And I support this site. ~M~

I would still use back gears and run it slower. Most of the time with machine work.....slower is better. Bad things happen very quickly.
thank you sir...very useful.....

holy crap why are you running that so fast there not intended to run like that.
the max rpm is 700, he is running 660

coaxial dials need to run as fast as you can turn them by hand so the lowest speed is ample enough anything more is nonsense,wear and tear friction vibration centrifugale force and so on.the speedo on my car says 280 but i never go that fast its pointless. keith fenner has a perfect demo of what im talking about.
running it too fast?

So what or who is tubalcain? A last name? Or a username? How did you come up with it. Been watching your videos for awhile and that always baffled me your username is mrpete, but you introduce yourself as tubalcain. Great videos by the way!

@gobtool
For close work such as indicating a work piece in with an indicator, I see no need to engage the spindle. These type indicators have limited use and really just take up space in your tool box. That's just my opinion. Learn to indicate the right way!
Ummm...that's a great way to destroy Your indicator... slower rpm for God's sake or by hand.... I bet running it that fast is giving you that "vibration" and a false indication
I use my Co-Axial Indicator to tram my mill, in conjuction with a brake disk. See my video at th-cam.com/video/dr_og5cTmu4/w-d-xo.html
Herb Blair I have watched that video. Good idea.
wat to fast
too fast too fast
First of all you have to realize that in these days there is no room for the words "perfect or perfectly " perhaps in your days there where no good ways of measuring some thing accurately and you could call "perfect or perfectly " at anything within .0001 of an inch but nowadays with the modern measuring ways those words are obsolete.
uummmmmm…. way way to fast. if you don’t want it worn and blown out after 4 parts i’d run it as slow as possible or buy hand… would you run your other dials in a reciprocating fashion that fast 😆
I was told there is a hole in the head of the Bridgeport for a coaxial indicators, so how or why didn’t you use it vice the collets
I have used it in some videos
