BTW - Bob, what does that little lever thing do, just under the dial? I've since discovered I also have a Mitutoyo DTI, along with the Tesa I bought ages ago, and neither of them have that feature on them...

There may also be some questions as to how it ended up in that condition.... short answer is, I have no idea! I don't recall buying it, so I must have acquired it in a job lot of other stuff at some point in the past. I only found it when I was moving literally everything in storage (strengthening the shelves with steel under-bars), and happened to glance in the tub it was sat in. There was some kind of oily gunk in the bottom of it, and this indicator... I don't actually recall having ever seen it before, so it's a true mystery how it came to be in my possession.  I'm just really happy to see it brought back from the dead - as Phil said, it would have been so easy to just throw it in the bin... now it gets a second life as a useful indicator once again  :nrocks:
Cheers!
Ade.

It reverses the direction of operation of the pointer.

Very happy to help -- just plain fun to solve problems -- I think we all feel that way on this forum!

One thing I was curious about was that it was 0 to 80 instead of 0 to 100, unless I got that wrong. I couldn't see for sure, but it looked like 40 was at 6 o'clock, so 0-80 is what I drew up. (if I was wrong, just let me know and I'll re-do it).
I love it when a Plan B comes together!

Very happy to help -- just plain fun to solve problems -- I think we all feel that way on this forum!

It's one of the things I like best about this forum!

One thing I was curious about was that it was 0 to 80 instead of 0 to 100, unless I got that wrong. I couldn't see for sure, but it looked like 40 was at 6 o'clock, so 0-80 is what I drew up. (if I was wrong, just let me know and I'll re-do it).

So... I had a look at my Mitutoyo earlier, mainly because it's handy here at my desk, and it's graduated the same way- 0-40-0. However, it's a metric dial... so I wonder if this one might be metric too?

Hang on a tic... I'll go grab the Tesa, which I know is imperial... back in a moment.


.


.


Back (phew). So, that's graduated 0 - 4 - 0 (thousandths), with each tick representing a tenth.  I wonder, therefore, if this is actually a 0 - 40 - 0 gauge, each tick being 0.01mm? Unfortunately, there's not enough of the dial left to be sure either way...

Maybe the solution here is to invent a new measure; let's base it on the average size of a gnat's reproductive member.... so graduate the dial 0-4-0, where each tick represents 0.1gc (gnat's cock) - so long as I can achieve an accuracy of "within a gnat's cock", I'll be happy  :D  As a side bonus, then it doesn't matter if it's metric or imperial!
Cheers!

Well, Ade, easy enough for me to re-calibrate the dial, unless Bob has already installed the present one.

oops I think I see a "2" on the right about where 25 would be if it was a 0-40-0 --- okay I'll make a new onr for that -- hope it's not too late for Bob -- sorry, should have asked!

And if you think it's mm then I can change the .0001" legend to 0.01mm. Well, work of a moment, I'll do that now, then you'll have a full selection of dials!

Lovely job.

Please have a look here:

and see how the bar above Verdict is discontinuous.

I could do it no problem, but I don't want to drive bob insane!

Also since I don't actually know whether the gauge is metric or inch, 0-40-0 or 0-80, I don't know which dial to modify.

But if Bob hasn't already applied the dial face, and if he wants, and can tell me which face to modify, I'd be happy to oblige.

I'm quite happy that this gauge doesn't look 100% original - it's part of it's story....

That's why I (only half-jokingly) suggested the "Gnat's Cock" measurement system.... I think it'd be cool to have a gauge that showed gnat's cocks - and I know it'd make my dad laugh :)
Cheers!

Okay great Bob, inch....that narrows it down.

Bob, can you tell from the old face if it was 0-40-0 or 0-80? Just out of curiosity.....

My guess is 0-40-0..... only because it looked to me like there was part of a "2" on the right side, about where second "25" would be on an 0-40-0.

If it were 0-80 that would be a "5" for the beginning of a "55".

But really hard to tell in the photos.

You take it easy Bob.

When you get better I got a similar Verdict for you to fix :D It's in much better nick than that one but it needs a new spring on the lever.

Oh, so it was an 0 to 80 then! Lucky I took careful aim with a scattergun!

Looks so different than when it started out, Bob, great work!  :bow: :bow: :clap: :clap: :beer:
