Wow, what an excellent video instruction. I am a retired military vet and started woodworking as a hobby, and love it. My Dad’s was a mechanical and civil engineer besides an avid woodworker and electrician, unfortunately, passed away 2 years ago, but on the bright side, I am so happy (like a kid in Christmas) that he left me so many tools with his engraved initials, so he is still with me. Some of the tools or accessories, I didn’t know what the heck there were for and one of them is a Vintage Sheer-Tumid Dial Indicator, in good condition, except, noticed dial was slightly sticky so your video gave me the confidence to take it apart, clean the plastic cover as well as the small rusted screws and dial works well and looks good. I am going to use it to calibrate my table saw blade and fence for the first time this week. Later on plan to disassemble it like you did as I saw some light rust creeping in. Again, thank you so much for your video. New Subscriber. Like the comment: “use your hands until they get tired” 😂 Keep those video coming. 😊

That Novus #2 polish is miracle level stuff. I used to use it to make scratched CDs playable back in the day.

[@joels7605]

I have Novus #1, #2 and #3. They're great, but DON'T use them on polycarbonate. I've had polycarbonate components explode (high stressed, in tension) because they came in contact with Novus. There's a little note on the back of the bottle about how it's not compatible with polycarbonate. They weren't kidding.

[@Milkmans_Son]

@@joels7605 Whut? Half the stuff they have on their suggested uses list are polycarbonate, the first being cd's and dvd's, the second being auto headlamps, etc etc.

[@joels7605]

@@Milkmans_Son Right from the label printed on the back of the bottle: "Removes heavy scratches and abrasions from most acrylic surfaces. Contains abrasives, not for use on eyeglasses, polycarbonate, or coated plastics." I didn't read the label and destroyed about $1000 worth of oceanographic equipment. We did break tests on polycarbonate after the failure. We tried exposing samples of polycarbonate to a number of different contaminates and oils, one of which was Novus. Novus was the only sample that destroyed the polycarbonate. Polycarbonate is normally extremely flexible and has high mechanical toughness. Novus soaks into the polycarbonate and makes it shatter like acrylic under low stress.

[@omniryx1]

@@DenysSene Machine oil is not the ideal choice. The weight is not the issue. Even the best indicator gearing is crude by watchmaker standards. The real issues are oxidation, which can make the oil gummy over time, and quantity, where virtually everyone, Quinn included, uses wayyy too much. Ideally, one would use a purpose-made synthetic oil. Fortunately, for a device like this one, what she did was fine.

[@machinistmikethetinkerer4827]

@@DenysSene try entering the world of horology and repair. Mention oils and watch the fur fly..and you wouldn't believe how expensive watch lubricants are. But for this application Starrett used to sell instrument oil for indicators. I don't know if they still do. I have a little left in the original oiler from 30 years ago. I use it on my micrometers and calipers, indicators etc. Quinn is right tho-less is more.

[@MegaLostOne]

One other thing that will cause the needle not to come back to the same position is you need to put a preload on the hair spring, I have done several Federals and everyone of them as I took them apart had a preload on the hair spring as well. Before placing the idler wheel back in I place the large hand back on and turn the hand two turns, then with the rack in the fully extended position I replace the idler wheel which now keeps the preload on the hair spring.

What a coincidence!! I happened to bump an indicator in my machining class this past Thursday and it stopped working. My Instructor gave it to me to take home and try and fix it, and I've been messing with it the last couple days. Unfortunately there was nothing I could do to fix this indicator as it had stripped some teeth on one of the gears, but this video was still educational and enjoyable as are all of your videos. Thanks Quinn!

[@MrDLWheeler]

That was an indication of multiple skills. Thanks for the video. Oh I watch the lock picking lawyer also.

[@charleshettrick2408]

This was a good video and well documented. I have recovered over 50 mechanical and about a dozen digital indicators from scrap drawers for emergency gages. 1.) Use Starrett instrument oil. Great to have in the do-it-yourself shop for lots of other stuff. 2.) Pry indicator hands off. Place 2mil cellophane over the dial and hands. From the outside of the cellophane, use opposing blunted small flat blade screw drivers to gently pry at the base of hand hub. Do not slip and hit the hand!, 3.) Frequently the indicators in our factory had bent stems. Most of the time the stem can be patiently wiggled out with slight force. If not, press out the short bearing and pull out the back. (Slit brass tubing, place around the stem inside the case, pull the tubing with needle nose against the bushing. If bushing glued, scrap the indicator.) The following is NOT recommended by the manufacturers. But, the stems can be straightened for emergency only. Place on a flat reference surface (surface plate, plate glass or similar) and roll. Note where high. Using blocks of wood, one as an anvil, gently tap the stem back straight. Then using a fine Arkansas stone, gently stone the stem to remove burrs.

[@danielabbey7726]

Valuable information, Quinn! Buying older good quality indicators and cleaning/oiling them is a great way to save money.

[@MikkelBachmann]

Top tip: for fine polishing, you can use toothpaste. It works great on headlights, plastic “glass”, final polish for knives and in wired etch cases it can be used to clean teeth.

[@cooperised]

Also as the last step for polishing scratches out of CDs and DVDs, if anyone still uses those...

[@bobvines00]

Quinn, now that I've seen this video I think I'll open up a 10-inch Starrett indicator rescued "from the trash" at work ~20 years ago when they still sold stuff like that. It had failed calibration, so went out as "scrap/trash." I've even got the original Starrett wood box it came in. :) Maybe I'll get lucky and find that it only needed cleaning and re-lubrication! I've always had a fantasy of using it as (part of) a poor man's DRO on either my mill-drill or lathe and even being "out of cal" it may still be more accurate than either piece of machinery!

Not only work on a soft surface to keep from scratching, but even better is to work on a large terry cloth towel. If a part happens to "jump" out of the assembly, when it lands on the towel it will not bounce and end up somewhere on the floor where it cannot be found. Been there, done that.

It would be overkill for this mechanism, but when I have something more complex with a assortment of unique screws (laptop disassembly, for example) I draw a sketch of the unit and stick each screw in its place on the picture (using tape, clay, whatever).

Does the hair spring need to be preloaded? I assume it's there to take the backlash out of the gear mechanism, and my assumption was that as soon as the bridge came off it would release its preload and need to be reset at some point. Am I wrong about that?

It probably does, but all the more reason not to remove it. 😁

EDIT: Blondi and Daan and correct here; both springs work in the same direction. Original: I think the retraction spring and mainspring are working against each other, to take up the backlash in the gear train. I think that'll improve accuracy at the cost of a little more wear on the components.

[@daanwilmer]

It doesn't really matter if they work with each other or against each other, as long as the main spring exerts force on the whole gear train it will take up the backlash. So why not let them work with each other?

[@Miguelito63No1]

hi this is Miguel again, Ihas learn a lot from YOU, GOD bless YOU

[@FinnoUgricMachining]

Two things I would like to add to Your encouraging presentation on fixing these. One: The plunger should NOT be oiled at all. Any oil in there will only create the sticky stuff that makes the dial indicator to fall into coma. The plunger and the bushing it is running in should be cleaned thoroughly though. Oil is ONLY needed on the bearings and the correct amount is really miniscule. So no oil in gears or the rack. One can use a needle to deliver the oil. Squirting it into there is bad. Two: The hair spring in there is to eliminate the backslash. Before the plunger is put back to it's place, the clock arms should be turned clockvise so that they become slightly tensioned. The number of turns depends on the dial indicator, some need more pretensioning because of the bad workmanship. Usually one turn of the arm is sufficient. Edit: In Your case the pretensioning was "automatic" as You turned the arm to it's original position without taking the arms off.

[@lazarjovic9948]

I wish I knew about the novus stuff! I recently restored a mitutoyo dial caliper, and I thought the dial glass was glass, but it turned out to be some type of acrylic. I used isopropyl alcohol to clean it, which clouded the plastic. Luckily a replacement was only €7 so it wasn't too bad

[@ronmccabe7164]

My $0.02 - my general experience with moderately gummy indicators is that they generally don't need to be disassembled, just degreased and reoiled. Especially those that have laid around without much use. Alcohol on the bearings, then relube. Explanation - most oils contain a mix of molecular weight hydrocarbons. Over time the light weight molecules evaporate and leave behind the higher weight hc's. There may also be some crosslinking making even bigger hc molecules. These have higher viscosity and of course are gummier. Now I've got me wondering if some synthetic oils may have a more narrow range of molecular weights or lower vapor pressure. Like ATF fluid, silicone oil, ???? HMMMMM?
