Notes –
- See Bruce Beveridge’s
rigging plan to reference most of the lines and sizes
shown(shown below). An excellent illustration clearly
showing all rigging is Ken Marschall’s "Farewell
to the Old World" painting showing Titanic at anchor
at Cherbourg (Art of Titanic, p. 58). Also see
the cover painting for Titanic: An Illustrated History.
- Types of ropes listed
are S – steel, H – hemp, and (B) Silicon Bronze
- The thread provided
with the new release of the 1:350 Minicraft appears
to have the correct diameter for 6/0 thread, and therefore
suitable as an all-purpose rigging material for the
mast and funnel stays (but the wrong color).
- Scale size in inches
has been rounded up to nearest thousandth of an inch,
as most micrometer calipers do not read beyond this
degree.
- Sized fly tying thread
in the range shown comes only in 3/0, 6/0, 8/0 and (occasionally)
10/0. Sizes shown in quotes are ideal sizes (based on
standard thread classification sizes).
The modeler must decide whether to size up or size down,
based on what is actually available.
- When selecting line
for mast and funnel stays, the modeler should select
a silver-grey color as per recent TRMA Forum postings
on cable material and color. See TRMA forum postings
on Steel Wire Rigging and Color, Dec 28 2003
- The lower several feet
on all stays (check photos) should be thickly painted
black to reflect both the color and the additional thickness
of the seizing of the cable above the eye, turnbuckle,
etc. See same reference as #6 above.
- All calculations done
to four significant figures prior to rounding.
- Sizes marked "est."
have been estimated from photographs.
- For rigging sizes marked
as estimated or undetermined, please forward any sizes
as discovered or determined to Art Braunschweiger for
update.

After some on-line searching
and consultation with a few fly fishing coworkers, there
appear to be only three commercially-available sizes (at
least in the US): 3/0, 6/0, and 8/0. While surgical threads
(sutures) come in other sizes, fly fishing threads only
seem to come in these basic sizes and one or two others.
This is probably because there would be no meaningful
difference to have in-between sizes, and from the 1:350
modeler's perspective you probably wouldn't be able to
detect such a fine gradation with the human eye anyway.
(And note, these are extremely fine threads.) The tables
note the ideal size and it's up to the modeler to pick
the closest match up or down. (A spool very inexpensive,
though, so if in doubt get an extra size up or down and
see how they look against each other.)
Also consider a little
beeswax run on the thread, and then running the thread
through your fingers, for protection and longer life (but
stay away from glue points and where paint will be applied).
Now here's the problem,
for those who want dead-on scale accuracy. The zero
measurement system used for fly threads (6/0, 8/0, etc.)
is archaic to the point where there's not necessarily
an exact correlation between diameter and number. For
surgical thread, yes, but not this stuff. (For those who
want in in-depth look at this subject, see the article
at the bottom of this web page:
http://www.flyfisherman.com/ftb/ssthread/index2.html
At any rate, I repeatedly
micd the brand I had, Uni-Thread, and the diameters I
got were reasonably consistent with the theoretical diameter
sizes for that number , at least with 6/0 and 8/0. If
anything, I would have to say they measure a thousandth
or so larger than spec, so that a thread labeled 6/0 might
actually have the diameter of a 5/0. (With thread, lower
numbers, larger diameter.)
I have listed here four
web suppliers of fly tying thread (including one in the
UK) with the sizes they sell. Note that two have 9/0 and
10/0, respectively, for those looking to model smaller
ropes.
