[@countrymule9623]

Mr Pete, I just came across your channel. I spent forty plus years in a machine shop. They called me the old man cause the young fellas coming in were all about CNCs and some of them couldn't sharpen a drill bit or weld a bandsaw blade. I was going to do another six years but due to a back injury I was retired last year. I spent the last thirty years at the last shop as the Operations Manager that was supposed to be only till one was hired. I was there for thirty-two years. Always in trouble for not staying in my office and being out on the floor on a mill or lathe. But I was the one called at three am for a emergency. We offered 7/24 services for our customers. Did my office work in the morning and the end of the day and kept a scrap paper notepad at alltimes for making a list of tooling, material ect.. that was needed or we were low on stock needed. I went through every job package before I put them on the floor for any print issues and special tooling that may have been needed. The largest lathe I ran had a 72" chuck and I could run 100,000 lbs between centers and 200,000 lbs with a steady rest. That was when I did papermill roll repair. The truck drivers that did the hauling for the mills were amazed at the lathe as it was as long and taller than their rigs. I enjoyed working in a machine shop and made a good living at it. I turely enjoy your channel and I'll go back and watch every one from your first one. Your basement shop is amazing! If you ever decide to sell any of your equipment please contact me and I'll make a trip from South Carolina. I'd really enjoy just talking shop with you. Stay safe and keep those vids coming!

I'd make a trip up to you when this C19 is gone cause I'd love to see your basement shop and just chat with you. I'm also a single father of a Downs boy or I should say man.

Yes

[@howardosborne8647]

That is probably the only tool that I was happy when it broke.

[@leisurehobby9980]

[@836dmar]

I thought it was surprising in the first half of the test. Didn’t move much. Yet adjusting that in small increments in a tight spot would be maddening. Better used to hold a mister or flood coolant nozzle.

[@Stevie_D]

I have a pile of the Starrett mag bases and they are ok for up to a 2' indicator before it gets too floppy. What drives me crazy is the center post unscrewing or guys adding a third 5/16" extension arm. Loose tips on the indicator seemed to be a big problem for folks where I used to work. Three things I always look for - repeatability, repeatability, and repeatability ... and if time allows I also look for repeatability. Interesting test - thanks for sharing with us!!!

[@paulrjones3]

I also find the NOGA fine adjustment scew in the base very useful.

[@mongomay1]

Thanks Mr. Pete, Did not realize how important it was to have a good magnetic indicator base until I worked for a Japanese Mfg company. Had to perform machine wear set-up standardization after grinding 300K parts by resharpening the grinding stones and setting the bottom stone to a base distance in the bottom guides. The machine self adjusted going upwards by a program instruction set during this dial indicator calibration of the grinding wheel. Don't ask me to explain, just agreeing to the results of Numbers 1 & 2.

[@mrpete222]

👍👍

[@barrygerbracht5077]

Rigidity is an important factor, but so is the ability to get the indicator into position and adjust it precisely. That is where the Noga with base fine adjust kills the old fixed stand types and makes it worth the money in my opinion. I haven't tried any of the cheaper Noga kock offs (buy once cry once is a moto I've taken to heart.)

[@dirkmohrmann8960]

I have a Noga knockoff from Amazon and it is absolutely useless. I could duct tape the indicator to a twig and get more rigidity.

[@Peter-V_00]

Proof the indicator base and indicator holding structure is as important as the indicator, all too many time I've seen people doing setups with indicator mounts a mile long made from flimsy small diameter rods, this video demonstrates the principal clearly.

[@larryschweitzer4904]

I started with a Chinese bar type. Now have the medium size Noga with the adjustment on the base. Makes it so easy to adjust and doesn't wiggle the whole arm around.

This morning I unboxed my new Noga after fussing with a cheap magnetic base. It’s the same one as #1 It appears there’s no need to save the box. Thanks for affirming that.

Not being a machinist leaves me to say, "that was entertaining," thank you sharing this video.

[@cns688]

Personally I would favor number 1 because of the experience shown by Mr. Pete and his knowledge of the decimal system, also I really like the way he put everything together for the experiment. Using the stick to point out certain properties could be from his teaching days, of course there is another reason which I am happy to leave to 'teacher' for now.

[@carlquib]

Another interesting experiment was done by Stephan Gotteswinter. He took supposedly rigid high quality indicator stands, zeroed them and then turned them upside down. The results were surprising to some. I was hoping Mr. Pete was going to do that as well with his collection of indicator stands. But none the less, an enlightening experiment. As Robin Renzetti regularly reminds us, "everything is made out of rubber".

I strongly recommend NOGA. MSC carries them online and usually has good stock and pricing.

[@tracylemme1375]

About twenty years ago I came upon the Noga. I have been a believer ever since. It is easy to adjust to a very tight tolerance. It is as sturdy as is needed and is very easy to use.

[@mrpete222]

Thanks

[@howardosborne8647]

One thing worth checking on the Chinese import mag bases is to see that the base contact area is truly flat to prevent the base rocking slightly. Easiest way to eliminate this is unscrew the stem from the base and with the base held in a milling vise take a light cut of both flat sections to flatten the bottom. Don't forget to switch the magnet to off position.

[@Freetheworldnow]

First test it on a surface plate. First see if it rocks. If not then go to the second step using a feeler gauge. 001 and poke it all around. If you mill the base I would try these tests again.

[@bcbloc02]

You should do this test on a flat bar with the indicator at a fixed distance say 8” from the base. Then flip the indicator over upside down and see how much the reading changes to show the deflection just from gravity. You should use the same indicator for every test though so the weight is the same.

[@mrpete222]

Good idea, but too late the job is done

[@johncooper4637]

After being frustrated with the number 2 style in allowing me get a proper setup I bought a medium size Noga. I love it.

[@Mike40M]

My old professor in machine tool design told a story about a now defunct lathe manufacturer. They tested spindle runout using a 3 foot long indicator holder. Which flexed so much that the indicator didn't show almost any runout.

[@mpetersen6]

I admit I really like the articulated type. As long as I am the only one using it. We had knockoffs at work and the arms would fail after about 4 months. Primarily due to people not believing you can over tighten them. My go to for lathe work has always been the Starrett with the solid bars. The bases with the rotating switch I have never been happy with.

[@howder1951]

Lyle I would add one more test, as we do for aligning couplings. Set up a bar in the lathe and set the indicator/magneton the top of the bar. then rotate 180 degrees and measure the sag of each setup, it is a very telling test , Enjoyed the test, although every setup is useable by a competent machinist and do exist out of necessity.

A clear polarizing lens filter could help reduce or eliminate glare off those dial indicators. You rotate the filter slowly and you adjust them for each shot.

[@mrpete222]

I have been struggling with that glare for years. I even took the crown off of an indicator, but it did not help.

[@IQof2]

@@mrpete222 it is tricky. There are situations where a polarizing filter only partially works. Something to do with the geometry of the light source, surfaces, and the orientation of the light waves themselves.

What scenario would you see in use that the gauge would be stressed as you are with the weights? All stresses on those gauges are on the tip of the gauge itself not on the stems. The stems should see no stress at all in typical uses.

[@David-hm9ic]

It tests the rigidity of the vertical post, the horizontal piece and the joints. Since the horizontal post is typically in compression or very close to it, most of the flex will come from the vertical post which this test loads very well. The actual load won't exceed the pressure exerted by the piston of the dial indicator.

[@445supermag]

It'd be interesting to see a test closer to how they are used, maybe put a large round bar in a 4-jaw with a 1" offset and an indicator running on it. Then use second indicator to read the movement of the first indicator. That way you would see the movement caused by the pressure of the indicator plunger. Might have to use a tenth indicator for the second one.

[@Freetheworldnow]

I agree. This would tell way more!

[@garthbutton699]

[@merek5380]

This is a special circumstance, but in lathes, a heavy indicator base with a solid post in the middle might not get the job done because it is common to put the indicator on the chuck and then rotate the chuck/indicator around a tool so that the tool is on center line. Since you are rotating the chuck you need a good magnet for when the indicator is under the chuck, and you need an arm that is both long, so that it clears potential aluminum jaws, but also a low profile to clear the bed of the lathe. Basically rigidity concerns give way to these things around lathes.

For the glare try using a polarizing filter (that can rotate) on your camera.

[@slordmo2263]

Ya, I would try that too, you set up your lighting, then when viewing thru the viewfinder, rotate and watch the reflective surface... it won't be perfect, but might you might be able to correct for problem shots....

[@MillersMotors]

a Circular Polarizer lens would do the treat. you can rotate it to hone in the glare reduction.

[@David-hm9ic]

In order for the polarizing filter to work the light source must be polarized as well. The sun is a polarized light source so they work outside. When I made my living as a photographer I photographed a lot of art. I put polarizing filters on the lights and a rotating polarizing filter on the camera lens. It worked very well but it requires that every light source be equipped with a polarizing filter and they all have to be oriented in the same direction. Another solution is to use very diffuse light, like a big silk or scrim and place the light above the silk. That's just the name for them; synthetic fabrics replaced silk decades ago. I use the Dacron that sailmakers use to build sails attached to large PVC pipe frames, about 3'x6' (~1mx2m). A black paper disc is laid on top of the sailcloth to prevent the specular highlight from going from the light source off of the dial and back to the camera. It works very well for watches so I would expect the same results from dial indicators.

[@greaser5691]

The blown-out highlights on the dial indicator faces in the wide view is because of the much lower average luminosity of the scene and how the auto-exposure on the camera reads it. The camera averages the overall scene to a "normal value" representing an "average" skin-tone, which in monochrome is about 18% grey. The majority of the scene is quite dark, so the exposure adjusts accordingly to give detail to the plate and the background behind the machine. Note how readable the closeups of 6 & 7 are. If, say, the plate was paper-white, all of the indicators would be much more readable, but the machine table and the background would be nearly black. People would (reasonably) opine using a darkening film on the indicators, but all this does is reduce the white indicator faces to a grey more in line with the background. A polarising filter will only kill bright specular reflections , of which there are not many in this setup, so all it really does is reduce the overall luminosity the camera sees and makes almost no difference because the auto-exposure will compensate.(unless the indicator crystals are polarised - which is unlikely - then we're back to a simple darkening effect).

[@jcknives4162]

an interesting video and certainly proving the NOGA served way above my expectations. I'm sure someone else would do this differently... People being people. So, friends of MR Pete, go out to your shop and do your own testing. Take your own suggestions for testing and use them to test. Then perhaps share your test standards and procedure with your results. Thanks MR Pete.

Good morning Mr Peterson. ☕🙋‍♀️👩‍🔧🧰. Ready to learn, Sir!

[@billgilbride7972]

neutral density filter sheet or window tint will give warm colors (3200k). Sunglasses for bright white things. Same for any shop windows, window film that is friendly with the color space you are recording in and fluorescent tube or LED it should color match (3200k) Not all LED products switch temperatures LTBBW. Anyhoo, cut some circles out and see if just a little bit of ND/tint, it should equalize the brightness. Apart from gauge blindness, there are also tweaks in software for fighting that. Black Magic Design's DaVinci Resolve editing software. The HD version is free and when it comes to color space control for clips, shows, remote segments. I say stay away from rental software. The idea being stick with one color temp. (5600k) is an option

[@billgilbride7972]

and further more.... the real culprit is that cameras do averaging and open/close the manual/digital iris to expose for that. If you can adjust that iris in MANUAL mode or if there is a toggle, you expose for the gauges, then pan/tilt the camera to the scene shot. If still in manual, you will be able to read the dials on a monitor. Good cameras allow for control of these things just like good gauges! Thank you!

[@mikefoster3547]

Use a circular polarizing filter on your camera lens to control the glare.

[@robgershman3886]

Are those all lug back indicators? Are you using some sort of adapter to mount them to the holders?

[@gordoneckler4537]

It seems to me that in actual practice the force on the indicator support system is the force generated by the spring of the plunger in the indicator and so the force is very small. What other source of force is there when the indicator measurment is taking place?

A quick question for you, what is the best way to make a two piece bronze bearing? bore it under sized, slit it and scrape it to fit or line bore it? Thanks for all the knowledge you are passing on.

[@PeopleAlreadyDidThis]

There are two challenges in photographing or “videoing” white indicator faces with clear lenses. One is exposing for the white, the other is controlling reflections from the lenses. An average scene, overall, reflects about 18% of the light that falls on it. Therefore, the autoexposure systems in cameras are calibrated to center on that value. But image sensors (nor film-remember that?) don’t have the dynamic range to register detail from black all the way to bright white when exposure is set to that average value. The indicator faces reflect about 98% of incident light, way beyond the camera’s range, overloading the sensor and obliterating the black markings on the faces in the process. Photographers call these “blown out” highlights. You can reduce exposure to darken the indicator faces, making the entire shop black at the same time, or try using neutral density (gray) filters on the indicators to reduce their reflectivity closer to everything else in the room. The other problem is actual mirrored reflections of the shop lights in the indicator lenses. A polarizing filter can help here. Using one on the camera, rotating it to intercept the polarized reflections from nonmetallic objects, can often, but not always, work miracles. It depends on the angles involved. You have to conquer both problems to achieve readable dials. The best baling-wire fix is to shade the dials...put them in semidarkness and hide them from the ceiling lights. Use something black.

Really appreciate your time you spent creating this lesson. Excellent demonstration on the rigidity 👍👍. What sort of load can the magnetic base withstand before it becomes detached would be another good test. Hope you have a good weekend.
