[@kenhutchens513]

I have learned so much from watching you John and Bob for DTI repair and refurbishment.

Dear John,Tell Bob he is doing a great job,helped me sort out a few second hand 'drop clocks' from Mercer.Keep at it, a real pleasure to listen and learn from you both.

I've got a Federal finger gauge that needs cleaning. Thanks for the info. I have cleaned two 1" DTIs and they are working great. Great work Bob. You and John have put on a great series.

Hi Bob. I have a Verdict DTI that needed a replacement spring lever. The original was the plastic one that they used for cost reduction and they split. Rang Verdict and was told they no longer repaired my version as it was obsolete, however, they did supply me with springs and two screws & nuts that hold the ratchet stylus in place. Cost me about as much as a second-hand DTI.

some information in there i'm not seeing elsewhere good work presenting some fresh content thanks guy's

[@davesage9190]

Thanks Bob and John: As I commented in one of your earlier videos you've given me some encouragement to dig into a few I have around here that are (as you might say) Knackered. Hopefully I'm using that term correctly :-) Thanks

[@karlhrdylicka]

Recon John would just say bolluxed.

[@krazziee2000]

great info, thanks for the video..

[@bostedtap8399]

I think Bob, has spent too much time in John's garage, ref starting to swear!!!. Great subject and video Bob & John.

Very fiddly I will leave it to you. Thanks for showing us how it is done.

[@jimsvideos7201]

Fussy little things, it seems. Any thoughts on using a plunger type indicator with one of those little lever assemblies to get into tight spots?

[@bobdixon6060]

hi yep I use one at work regards bob

[@tristanpatterson3843]

Bob is made for youtube! Get him a channel!

[@Gkuljian]

I had no idea those had a helical movement. I'm surprised I never had the curiosity to inquire. I just figured it was gears.

[@ianbertenshaw4350]

99% of the time the stylus length won’t matter as you are only using the dti as a comparitor , that is why if you need to actually measure something like the thickness of a piece you set up a stack of gauge blocks and zero the dti to it and then you would pay attention to the stylus length and angle if you needed dead nuts accuracy . Another rippa video mate !

[@1jtolvey]

SAY HI TO YOUR BIGGEST FAN FROM ME , GRAND-SON !

[@chuckpickering6040]

Shouldn't this be Part 7? would Bob repair a Chinese DI and DTI from Little Machine Shop. I would donate them if Bob can repair them and you could give them away on the SNNC.

[@bobdixon6060]

hi yep I will have a go at fixing them just get in touch with john for his address regards bob

[@TheChipmunk2008]

Me: I've seen these videos, why is youtube suggesting...OMG THERE'S A NEW ONE [click finger breaks speed of sound]

[@ladywithalathe3770]

the lesson would be so much better, if you had all the items you tell us about... i don't understand this bluetack stuff... likening it to another name brand product i have never heard of is really of no help.... seeing it in action would certainly explain a lot.. you show us the hairspring, but how does the lever activate the spring?... some better close ups would also help... i realise it is all very simple for you and i appreciate your efforts to enlighten us... but after watching your video for the third time, i still feel i am very much in the dark, and hesitant to open up my first stylus dti

[@bobdixon6060]

hi ok will show you the proper stuff witch I have just received in action witch spring the one that operates the lever or the pretention spring as to close ups the camera is pre set and that's johns department regards bob
