Outer Limits 4x4 Board

These things are on ebay fairly cheap, but they are just chinese made things. Are they as crap as I assume them to be, or are they actually worth grabbing?

My current inclination is just to get a set of conventional ones.

Get a set of LiMiT verniers, theyre about $40 from memory and of half decent quality

Go the digital, I've been using and abusing one for 2 years now - no problems. Been able to go from thou to metric is handy.

I have used a pair of those exact ones. They seemed to be accurate enough. I was using them to measure electronic parts to design a PCB, so I was measuring down to about +- 1/10mm and everything worked ok when the PCB was manufactured.

I'll stick to my digital Mitutoyo Absolute one thanks, admittedly it's pricey but the quality is 1st rate. Being able to change from metric to imperial is a great feature, all the Chrome/Moly tubing and sheet we use is Imperial and everything else is Metric.
Regards Andrew.

We use a Kincrome digital set daily at work.
Seem to work well.

they work ok, and they are accurate, but you need to keep them dry, and keep dust and grit away from them. Otherwise they will be toast in no time. I use Starret digital verniers at work, cost me about $150 for a 200mm set, even they play up if not careful.

I'm bored, and pedantic.

"Vernier" is the pair of sliding scales used on non-digital measuring devices. "Digital" readouts are not verniers.

"Micrometer" generally applies to measuring devices using a fine pitched screw thread to adjust the measuring aparatus. Most micrometers typically use a vernier scale to provide excellent accuracy. Of course, Americans confuse the issue, because a micrometer to them is a micron, or one millionth of a meter - the rest of the world calls that a micrometre.

Digital calipers are great - I give myself a headache trying to read vernier calipers, although my calipers are imperial with a needle and dial - great for reloading imperial calibres.

Yep, they're fine.

Been using a 200mm one from them dudes for about 12 months, no probs.

Im a fitter/turner by trade and have used them for roughing stuff up but don't trust them for criticle measurements when machining. i still prefere traditional vernier calipers with dual scale as you can identify nominal sizes either metric of imperial much easier. Theres just no substitute for Screw Micrometers both internal/external when a tight tolerance needs to be achieved.

My dads a fitter and when he did his apprenticeship a set of vernier calipers were considered evil. The place he worked refused to have vernier calipers on the premesis. After he finished his apprenticeship and got into the real workforce, everyone was using them, but to this day he still refuses to use them. Hes got about 6 different micrometers of all sizes which he insists on using.

I think when your machining something there is no substitute for a micrometer, but in many many other situations a set of calipers is more than accurate enough, and usualy a crap load easier and quicker.

calipers are quicker when doing large tolerance bores, and one decimal place tolreances on the OD..... i only use a mic when doing a finishing cut, or an inside mic, or telescopic guages for IDs. Used to always use slip guages when i did my apprenticeship, but i haven't seen a place with them since.
