DTI Care & Repair with Bob Part One

Part one in a series of videos
Strip down & fault finding

[@vicpatton5286]

Hi John & Bob Fascinating work! First time I have seen the interior of a dial indicator. :-) Thank you Bob for sharing your skill and Thank You John for introducing us all to Bob, hosting & camera work. regards vic

[@funksterdotorg]

Thank you so much for making this series! It gave me the knowledge I needed to service my two Mercer gauges without doing them any harm.

[@willcarson8392]

Thank you so much for this series Boost and Bob, I had a 1 inch Mitutoyo that I had broken in 2005 and never had the courage to try fixing it. This series gave me the gumption to tear it apart and try my hand at it, back in service once again!!

[@Sodabowski]

Wow I actually understand what Bob says! All the years watching your videos are paying back XD Thanks guys, very informative and useful indeed!

[@HaraldFinster]

Can't agree more. Watching doubleboost for many years probably buggered my "Oxford English" learned at school ;-) As we are just talking about language: I have been told that the indicators with the linear motion stylus as shown here are called DI ("dial indicators") whereas the ones with the articulated stylus are called DTI ("dial test indicator"). Hope you don't mind me nitpicking. I am just curious. All the best and many thanks Harald

[@goldeee666]

a very informative video. highly skilled fellow mr bob. well filmed too. great running commentary. much enjoyed. valuable info here many thanks

[@Ogma3bandcamp]

This is fantastic John. Thank you Bob, great job.

[@tried2851]

Great video Bob, I have repaired a few clocks in the past with an identical approach . Retired Instrument Tech.

[@gordonburns8731]

What lovely work by Bob... the craft of the watchmaker!

[@britishreaction54]

Absolutely fascinating and very informative. Looking forward to next installment. Bob is a natural at explaining things.

[@zephyrold2478]

Hi John and Bob, I am sure that Bob already know this but did not think about it at the time, the cover seen at 11:49 can be rotated a little bit, and by rotating it you can control how much the gear is in contact with the stem, and because the former "repairman" had adjusted the gear to tight towards the stem then it wont go back properly and it might also feel a bit notchy, I had one that had this exact problem. Nice to see Bob is a natural KZbinr, a good old handmade thumbs up to all three of you.

[@whitehoose]

This has been a really good addition to your channel. Something a bit different, and a guy who obviously knows what he's doing and just as importantly manages to explain it well - I hope there will be more where that came from. Whenever I remember and finish one of the small 250ml pop bottles I cut the bottom 11/2" off and screw it onto my working board ... they have 6 "dimples" in them, ideal for tiny parts. The shape makes it easy for even my fingers to slide out small screws and because its fixed to a board - you'd have give it a hell of a crack to spill the contents. My current board has 8 pots and the board is held onto the bench with a small G clamp - But horses for courses you work how suits you best. My other more recent "discovery" is a magnifier that clips onto my 4x reading glasses. Its an e-bay special "Clip-on Eye Glasses Binocular Magnifier Eyeglasses With 3 Lens 1.5X,2.5X,3.5X" - £3. It suits what I do and how I work - Clipped to my strongest reading glasses it gives a combined 7.5x magnification which works for me.

great to see bob in action !!! big hands , very small parts !!! Very interesting !!! we really like this kind of stuff !!! this is my first look inside of a clock gauge . welldone bob and mr. boost !!! can we have a look at bobs shop ??? best regards

[@gm0hzi]

loving the new series

[@houseofbrokendobbsthings5537]

Brilliant! I have ham fisted my way though a few of these. Bob just tuned me up, and I will be smarter the next time. _Dan_

[@MaturePatriot]

Very informative. I have a couple of gage's I'm going to look at. They have been around for a while, and are sticky! They may be an easy fix now. Thanks John and Bob.

[@injun-gman6216]

Awesome! I've always wondered what the movement looked like on an indicator gauge. Thanks Gents!

[@Blakey1931]

Been looking forward to this 👍

[@bobdixon6060]

hi all thank you for the comments

[@bernardbouchereau215]

great video. Bob did a fantastic job on my churchill gauge. quick turnaround and cool box to protect it on its journey all the way back to New Zealand. thanks Bob and John

[@alanhill4334]

That was fascinating, looking forward to part 2. Good photography, you don't realise how small it all is until the shots of Bob with the loupe.

[@krazziee2000]

thanks for Bob,, very educational ,,

[@pddpup7767]

Excellent vid. Thanks John and Bob

[@johnbaldacchino7731]

excellent stuff Bob, well done John give us MORE !

[@dougmclaren4328]

Excellent video, very informative. Thanks Bob.

[@retromechanicalengineer]

Great video. Looking forward to some more of Bob's wisdom.

[@mikeysgarage3697]

That's a great video, clear and informative.

[@Maddogtrev66]

Thank for a very interesting video hope we will see more of Bob soon

[@johnambler3107]

Very informative Bob thanks for sharing your knowledge. I’m really looking forward to the next video.

[@bcbloc02]

Great video, very educational and loaded with tips, thanks for doing the video!

[@baldprisonguard1]

This is brilliant. Thank you for this.

[@paulmorrey733]

Cheers Bob great video

[@jimsvideos7201]

Thank you both for the time put into this! One thing I've found for small parts is a strip of double-sided sticky tape; obviously it's a bad idea for the springs though.

[@grahameblankley3813]

Bob, more more more!!!

[@mauriceeley621]

Enjoyed this one John, Bob,Mick and Stig in the back ground wanting to join in .

[@jcs6347]

John and Bob, I really enjoyed this video and I would recommend that you two work together and make some more videos. Thanks for sharing!

[@shawnmrfixitlee6478]

aHH , so enjoyed John . Great share Man !

[@davesage9190]

Fantastic. Keep these videos coming. I've never had the courage to take a DTI apart (which Is sort of strange because there is noting to lose). But watching Bob do it gives me some encouragement. I have a few around to try. I'd also like to see what's inside and how to fix one of the (name escapes me) ones that are very sensitive and have the little lever on the end. I have a few of those around as well. Thanks Bob and John

[@noelhenderson700]

Dial test indicators are the "ones that are very sensitive and have the little lever on the end". They typically read in tenths of a thousandth. Clock gauges or dial indicators, (in North America), read in thousandths of an inch.

[@stevenkirkham2297]

Hi John and Bob. How the hell does he do such intricate work with them big dread hooks. Nice video well made and narrated thanks to both of you.

Yoghurt pots or on the table, with me the parts would get lost as I am clumsy and small parts have no chance with me, or the cat would jump and scatter them. Very nice video, very informative looking forward to part two.

[@jeroen-surf]

Very nice video!

[@Johnkels100]

Thank you both excellent.

[@machiningbasics1729]

Lovely stuff

[@paulfisher6587]

Fantastic, Thank you

[@remberto2008]

Sorry to tell you, but Bob should get his on channel. :)

[@marderbeast]

Probably been dropped on to the plunger. thanks Bob for the insight.

[@davidbawden6567]

Top notch lads...

[@cliffjones1511]

Nice , More Bob

[@markhodgson3045]

Good one bob

[@noelhenderson700]

Well, I will definitely have to get my hands on a jeweler's loupe now.

[@davegogo10]

Very interesting video but I think there is a better way of securing removed parts. Use a tray (preferably with a lid) that has been stuck down to the work surface with good quality double sided tape. Cant get knocked over, jostled or parts being blown away by unlikely but possible gusts.

[@shahilkhanpthan3696]

Good video

[@scheppach69]

Bob you are an expert at what you do, have you ever considered using coffee jar lids or similar to keep the various components in?

[@bobdixon6060]

hi Kevin no I don't like putting parts in things as I have a tenancy to drop things and if I drop sum thing heavy and it catches the edge of the lid it will launch them across me workshop

[@gordonburns8731]

Does Bob have a KZbin channel, John? I find a certain catharsis in watching craftsmen at their work.

[@bobdixon6060]

hi I can not believe its bin that long that we did this

[@robertklein9190]

John, let the dog out. or is he into fixing indicators? I wouldn't only lose the screws, I haven't found the screwdrivers yet.

[@loftsatsympaticodotc]

Here at Machineco in Montreal.. well it took me awhile trying to find out between the accent and terms of reference, and lack of anything in the opening screens or descriptions below, what this was all about. NOW I know; it seems a "clock gauge" is what catalogs, mfr's and machinists call a 'dial indicator'. I wish more fellows would not just drop into their local jargon and abbreviations and at least spell it out up front.

[@127069]

how can I contact bob so I can send him some knackered dtis to mend for me?

[@bobdixon6060]

hi just send john a email and he will let you no haw regards bob

[@chrisstephens6673]

Great video but would question the idea of 3in1 being anywhere near a clock as it is famous for gumming over time, just look at what sits on the top of the tin.

[@bobdixon6060]

hi well yes it will in time but if you want to spend £20 on a tin of instrument oil go a head but as I sad if you only have one to do and you ant going to do any more wats the point and if you have taken it to bits and got it back together working then you can do it over a gane when it starts to gum up regards bob

[@chrisstephens6673]

@@bobdixon6060 you make a valid point but perhaps the cheap option would be a quality sewing machine oil used very sparingly.

[@bobdixon6060]

@@chrisstephens6673 hi well if you have it on hand but its hydroscopic

[@chrisstephens6673]

I did not know that, I was lead to believe it was a refined mineral oil, and 3in1 was veg based(or was originally ). personally I still have some of the proper instrument oil which will last about 35 lifetimes at the rate I use it.

[@bobdixon6060]

@@chrisstephens6673 hi mine will to .sewing machine oil is designed to brake dawn if you think if the oil gets on the fabric it needs to cum off easily so its blended to be biodegradable
