A good set of vernier calipers?

[Tim.243]

If I was wanting to check batches like the re-loaders then I would set up a plunger DTI to a gauge length and check away....no different than checking batch work in the inspection dept of all engineering firms as that is what you are effectually doing.
Set a ZERO and read the plus length then set aside in batches for what you need to do...

I am sure you would have more fun with it...

I bought Draper, machine mart, sealy, all fell to pieces, faulty battery clip, lid, got fed up with that, bit the bullet & bought Mityuoto, well made but too accurate, I mean how accurate do you have to be? does it make that much difference? it just seems to make the job more fiddly, but I'm no expert.

How fiddley can it be to put a new grease cartridge in the grease gun...

Do you really want vernier calipers or is it really digital calipers you want?
There are loads of digital calipers out there, but if you want GOOD digital calipers, buy Mitutoyo
The 500-196-30 is good enough for what you want but will cost the thick end of £80

+3 (or 4?) for mutitoyi - been using mine for years and they just work.

You can buy cheaply or buy quality
Cheap ones will get you most of the way but the final few ‘yards’ are the expensive ones when buying measuring instrumentation.

Mine worked great, and probably still do - they were that good, they went ’walkies’…..

Vernier calipers and dial calipers are two different animals.

Not fiddley, just slippery, & I don't get a different reading every time I look at it. I need smaller hands & less decimal points. My farmers favourite tools are mole grips & a good hammer.

And bailing twine...

You could also consider Moore and Wright, they offer dial and digital calipers of decent quality at reasonable prices. The dial calipers are either Imperial or metric and don't have batteries to expire just when you need them.

Thanks one and all.
Having spent enough time on H Roberts I can only say.. ooh shiny lovely, have my xmas present sorted.

However it really does make me wonder, as others have said we are using the wrong tool for the job and if I want precision at the thou level I would be better off with a DTI like the Redding Instant Indicator.

Anyone used it to justify the 167£ that it's going to set me back?

 

[lillico]

Thyis is the measurment that I work on, a different system, but it works okay.

As well as a calibrated digital vernier, you need to develop the touch that knows when you're pressing the sliding part against the bit you're measuring just hard enough to get an accurate reading. press too hard and the reading will change by a few thou.
That's not the fault of the caliper, it's user error

As a person who knows friends that run workshops that can mill to a thou on gearbox assemblies by hand I can say for certain I don't have his sense of touch and that I need to eliminate the user because of it's error...
Sadly he refuses to do all of my loading for me.

That is where a plunger dti will take that error out the window....go in the pass bin no go in the no pass bin...

 

[JTO]

I think I would go for a dial caliper if I had the choice.

 

[Whitebeard]

In the world of measuring equipment you gets what you pay for, I have been using a mitutoyo vernier calibre since I finished my apprenticeship in 1981 and they are still super accurate, I have been using a mitutoyo digital caliper 28 years and it is also still spot on

 

[Alantoo]

The talk of longevity of good equipment reminded me to take a photo of the Imperial micrometers I have been using in the forge since the mid-1970s. The widow of an engineer let me have them to help me on my way when I first started out...Brown and Sharpe and Starett with a Chesterman combination square all in a cabinet along with Vee blocks, a surface gauge and the surface plate to match. Note "The Unique" proto dial gauge top left corner! They don't owe anybody anything after 70 plus years and still work fine.

The internal micrometer is a Moore and Wright and still has the 40 year old junk shop £10 label on the bottom!

Sadly the Mitutoyo vernier is probably the least used of all...only 10 or 15 years use out of it before declining close focus made it difficult to read.

 

[Druid]

I prefer dials for the sort of readings required for reloading.

 

[Gm81]

Mitutoyo would be my choice for digital type.
