stupid safety rulers...

I wanted to buy a replacement 12" stainless steel ruler. Shopped all around
town. Apparently almost all now have rounded corners, presumably to keep us
from hurting ourselves, so the graduations don't go all the way to the end.
So you can't use them easily to make inside measurements...
So I can be trusted with a chain saw, a nail gun, a milling machine, etc.,
but I need to be protected from sharp corners on my RULER ???????????

(It does look like Grizzly has one that it as at least squared off at one
end with graduations clear to that end.)

To check your rule, get one a meter long and check it against the
distance travelled by light in vacuum in 1=E2=81=84299,792,458 of a second

You should avoid using the end of any measuring device; that's where the
error is.

For example, the original meter standard is the distance between two lines
drawn on a Platinum-Iridium bar, not a plank of metal exactly one meter
long.

Check McMaster--they've got more than a dozen 12" stainless rules
starting at under 6 bucks, most of them squared and with graduations to
the end.

Or treat yourself to a Starrett combination square, which includes a
12" chrome ruler of Starrett quality.

Now now...

The ends of rules are not to be used anyway due to the 'end' effect of it
shortening.

One is to use from the "1" marker where the end might be dented or warn.

If you have to use the tip corner - order one from a major scale line.
e.g. from Starrett themselves.

That would be true for tape measures and yardsticks but not precision rules.
If they are manufactured to federal specs, the baseline for all measurements
to prove calibration is the end.

Thirty-eight bucks buys you the Starrett.

Buy it once. Buy it right. Own it for life.

$25 got me the "Pinnacle," from Woodcraft. In truth, I think it's an
excellent piece.

I have 2 of these:

When I can't find either one within 10 seconds, I break out in a cold

With your handy, new, pocket Furlongs per Fortnight lightmeter?
Excellent idea, Toy. Gotta go now. My MrFusion is coming out of the

I think I need that one to augment these:

I have all but the 36" version, and they've worked out great for me.

I think that mindset comes from using cheap rules.
I buy expensive rules, now, after learning my lesson. I check them
before leaving the store, or send them back if they don't check out.

Guess I'd better throw away my depth gauge then.
