I don't know about a "real definition", but I've always assumed
that there is spring loading in the train from point to gears which is
stiff enough so it does not affect the reading, but soft enough so it
minimizes sudden shock to the gear train so the gear teeth do not get
they don't explain it either.
If you condense everything on that site into one sentence it's
"anything product we can't service is junk". It's a bizarre website with
strange mixed messages.
Once you rule out chinese and dubiously rebadged stuff, dial indicators
seem to come from mitutoyo, starrett, mahr federal and teclock, and the
prices seem to vary widely and I'm trying to figure out why.
I have a teclock and mitutoyo 1" travel 0.001" indicators. There really
doesn't seem to be much of a difference between them. Neither feel cheap
or like works of art and both came with impressive amounts of meaningless
paperwork in the boxes. Neither would be worth fixing if they fell on
the floor, so service is not an issue for stuff like this, at least to me.
I suspect that just can't fix anything to start with. That entire site is
just one huge rambling jumble of nonsense. I don't even see anything for
sale on it. Maybe it a blog from a collector or junk hawker on ebay.
I don't see anything useful about that website in the first place. It is
full of strange stuff like this
"In Brief: the best dial test indicators are Swiss made."
"Swiss workmanship took a nose dive in the new century..."
Great, sign me up. It gets even more confusing too:
"You have 4 commonly available brand names to choose from: Bestest,
Compac, Interapid, Tesatast. All of these are made by the same
manufacturer in Switzerland. There's nothing better on the market, in our
again, followed by
"Swiss workmanship took a nose dive in the new century and the result is
that many Compac indicators are currently out of production while the
manufacturer attempts to revamp its organization. "
So compac is the best, but it's junk and out of production, but the same
as three other brands, except the Bestest ones which have shitty bearings?
"Compac indicators have oversized ball bearings which almost never need
replacing. Bestest bearings are very susceptible to damage."
I'm going to pass on this joke.
The only site I've seen that actually has spec sheets on stuff like this
That still leave the question of what does "nonshock" mean? Starrett seems
to use it on models with this as an option.
