vernier caliper/re loading


Recommended Posts

When reloading you need high level of accuracy. Some years ago I bought a cheap digi one from Aldi, it did not read the same as my Mitatoyo and read inconsistently. Ok if you need to measure to the nearest .5mm but thats about it.

If you want a high level of accuracy you should be using a calibrated micrometer not a digital caliper gauge. I've had plenty of the cheap sets clamped to various machines as well as hand held and the only issue I've had is swarf getting inside the mechanism and damaging the reader. That would have happened with a dear set too. These cheap sets are incredible value for money and very accurate and repeatable in my experience. If I'd had to buy Mitutoyo I wouldn't have even one set.

You may also find the amount of pressures put on the calipers will vary the reading.

I'll change that to "it will" change due to the amount of pressure.

You can calibrate your own to a suitable standard using a fixed object, ie a bolt, nut or a dummy round.

I managed a calibration lab. We've tested a fair few of the Aldi and Lidl digital calipers and have always found them to be as accurate as many costing 10 times the money. It's simply down to the question of refinement.

 

If you are not using it on a regular basis then just remove the battery.

By decent gear, Mitatoyo are the best,

That' right. I'be had mine for about 25 years. I use it a most every day. No battery, no dial just a sliding scale. A micrometer was suggested but although it will do the job it is a bit of overkill. MITUTOYO all the way.

i have just got my digital vernier caliper out and the battery has leaked and it no longer works, should i replace it with the same or a Dial vernier caliper, what do you re-loaders use and recommend. thanks in advance Nick

There's nothing 'digital' about a vernier anything.

I got a hornady digital set, I can use a vernier scale or micrometer no problem but digital's much more convenient. I would say you're as well off just getting a cheap set though as that's all the hornady ones are - I just happened to pick them up while buying other loading stuff. The bonus being you can switch between metric and imperial which is handy at times.

Well I bought a couple of these cheapo Aldi calipers (note to others they are digital NOT Vernier) & they read exactly the same as both my Mitutoyo calipers & within a gnats cock of the Moore & Wright or Starrett micrometers.

I use the Aldi ones often on the lathe & only for the finicky stuff do I break out the real ones! It's quite handy always having a calipers to hand when they only cost a tenner!
