The Starrett Buy American thread reminded me to chime in with a personal
I've had mine for two years now - it's great! Used enough to be on Battery
While I don't have a machinist's reference point to calibrate it to - I've
measured a number of off the shelf items - drill bits, chisels, screws, etc.
This unit is within a few thousands of what you'd assume it would report. As
for accuracy, it again seems to put up data repeatable to a thou or so...
If all the units are as nice as mine, I think it's a great buy at $16.

The repeatability is precision. Accuracy is how close to the real value
"0.900, 0.901, 0.899, 0.902, 0.898" is precision.
"1.00, 0.50, 1.50, 1.25, 0.75" is accuracy.
You want both. "1.000, 1.001, 0.999, 1.002, 0.998"
Anyway, for $16 I want one too. I'm considering a Stanley 136, because I'm
looking for "neighborhood", not accuracy and precision.

Don't need it anyway. Still want one, though. But, you're right, a
mechanical caliper is just fine. (I keep a slide rule in my bench drawer,
and use it now and again.)
I gotta wade in here. You DO have to ground a caliper - and here's a case in
My brother had to wear a caliper as a boy, it's a device that is two metal
rods hinged, at the knee, that supports the leg. He had to wear it for
extended periods following operations. The metal bits were kept off the leg
by leather but, at the top, they were exposed. The top terminated near the
upper thigh, and, on a good day with the right conditions, you could scuff
yourself over the carpet and touch the bottom of the caliper, resulting in a
discharge near the top (where his boyz were).
It were guar-ant-eed to get his attention.
So, in answer to your statement, no shop explosions, but it did make my
brudder explode regularly.

You'd be surprised how many people find it hard to read a vernier or
dial caliper! They just don't know how to read it, in most cases. As a
machinist/moldmaker, my most used tool is a 12" dial calipers.
I have a cheapie 6" at home I use for everything...machining, planing, etc.
What's that, Stubby? (What fool works in the shop
without their glasses on?)

I've been thinking about attaching one to my planer for quite some time,
but haven't pried open the wallet to buy one to drill holes in. This may
be the ticket if I can concoct an attachment method that doesn't look
solution flexibility for use, having inserted a bed extension. The kind
one uses for thinner stock, and to reduce snipe.
Preferably something that doesn't require me to do addition including
measurements in 32nds of an inch.
If you get the time. And are interested. And don't mind sharing. For
I don't want much, do I? ;-)
Doh! Hadn't considered that possibility. Maybe making the sled a precise
even thickness (1" sounds good) might work.
Haven't had any problems with snipe on my planer, but use of a sled for
thinner stock is something to consider.
If you have the patience to wait for when I get a round tuit for that
task, I'll be more than happy to share.
