Spoke gauge

Does someone sell a gauge --just a set of slots, really, to
differentiate --1.5 from 1.55 from 1,6, 1.7 and 1.8mm butted spokes?
Gauges except maybe ones Jobst designed require you to know that,
because they further assume stiffness of th stainless steel of that
size.

There's another thread on variable spoke tension specs. You'd be
uniformly wrong by as much as 80% on that difference.

Couldn't you do this with a micrometer?

Dear Harry,

The Park tension gauge comes with a round notched disk for checking
spoke gauges.

Or you can buy a spoke ruler like the DT model, which has the spoke
gauge notches:

Here they a

If you want to check 1.55 versus 1.5 or 1.6, you probably need a
micrometer.

Cheers,

A dial (or vernier) caliper will suffice; the difference is 0.05 and metric
ones typically have a resolution of 0.01mm (imperial are usually 1/1000"
which is 0.0254 - still good enough).

Dial (or vernier) calipers are generally cheaper, more useful, and capable
of standing rougher treatment than micrometers.

Sure, on the side of a Phil spoke rule

Thanks,all. The SS spoke ruler and Wheelsmith tensiometer I have both
neglected these essentials. Which may explain why they're no longer on
the market.

For onlookers, a difference of .1mm from 1.5 to 1.6 accounts
accounts for a 20% difference in estimated tension reading on a Park
or Wheelsmith tensiometer at around the 100kg level. Confusing a 2.0
for a 1.8 mm spoke could cause a 60% error in tension if you didn't
listen tot he pitch, instead.

I see the DT Swiss ruler would let an aero / bladed spoke owner miss
tension by 20% if she failed to detect the difference between an .9 X
3.1 and a 1.1 x 3.2

Metal knitting needle gauge. Plastic ones are 14swg and larger, and
are holes not slots.

Dear Trevor,

A hole gauge for smooth needles won't work very well for sizing
threaded spokes accurately.

Spoke threads are rolled into most spokes, making the threads slightly
thicker than the rest of the spoke:
