Yes, that's right - but if you can measure 2.67mm with your ruler you're a better man than I, Gunga Din.

 

Would I get away with 2.7mm? 

 

I’ll more than likely do it 3mm

That's what Vernier gauges are for. Set the Vernier to 2.67mm, Position on signal arm draw 2 lines with an ultra fine fibre tip pen and then paint between the lines. If you don't have a steady hand then use masking tape. Job done!

I use waterslide transfer stripes so I don't have to paint them at all - but I still have to cut the transfers to the right width!

Although I have/use a vernier I think I'll get away with 3mm (or just under) and I will more than likely mask it off and use my airbrush

[Graham T]

That seems like a lot of effort - setting up the airbrush just for that I mean.  I'd just use the old "hairy stick" personally!

My airbrush is permanently set up ready to use and I generally use Vallejo Air paint which are ready to use out of the bottle....I find the clean up afterwards requires the most effort

Very true and a micrometer and a depth gauge, I just thought that using it in this instance may be a little OTT

 

I don't think I'll notice if the stripe is 0.33mm too wide

[Gedward]

But seriously, a vernier is just another item I'm putting off buying for now. No doubt I'll get one when needs must.

Proper engineers, like wot I is, call them Verynears.

The ones I have for work have DRO. I refer to them as large or small digital spanner. The one I use at home actually has a vernier.

The one I use at home is a cheap digital one for about £10 from Aldi or Lidl and is almost identical to the one I have at work that cost five times the price

Alas, I've only got an 'Ology.

[Graham T]

I must confess to having both a vernier and an airbrush.  Neither of which I use as much as I probably should.

Serious question - how do you calibrate the digital ones?

I must admit the spray pattern with the vernier is more accurate than the airbrush

I think they are checked against a specially calibrated one?

 

We just tell the inspector during the annual ISO quality standards audit that you don't use them which in a way is true because we only design and assemble 'in house' all components are made elsewhere to our drawings/specifications

That's what I thought but how do you adjust the readout?

It's not something we get involved with but I would imagine the calibration is done off site by a dedicated calibration service

[lezz01]

I have a dial on mine so I can't comment on how to calibrate one with a DRO but there must be a set button on it.

I find the digital read out ones to be a real pain when you take it on site with you and the battery is dead...hence why I always carry a spare battery in my site kit

 

It's been many years since I've used a proper one

 

What we have is good enough for our purposes as a draughtsman's spanner

Thanks Lez. Mine has a dial too, with a rotating bezel and a locking screw. I've never owned or used a digital one, hence my question.

There is a zero button

The facility to switch between metric and imperial at the touch of a button comes in useful

I worked for over forty years as a toolmaker we always called a vernier a guessing stick. Both digital and analogue. Micrometer checked against slip gauges for anything accurate.

I too was a toolmaker (press tools and moulds) and I totally agree with you but sometimes, as in this case, a micrometre is not appropriate nor the right tool for the job. I still have my DTI and slip gauges but my face plate isn't much use as it needs a regrind and I don't have access to a surface grinder.
