um last i check the clew
it the part of a sail that is opposite the tack. clearly it haas another meaning here. i'm just asking out of curiosity...
also, i assume the rope is not braided, and that's whats causing the twisting.
to me it would seem a lot easier to bite the bullet and spend the money to get some good line
in there. Can you use Spectra? (more curiosity here, are fly systems supposed to be static or dynamic
?) for the quantities you be buying i'll bet you can get a reduce price.
is a square metal block
with ,typically, 4 to 5 "slot's" inside it. In each slot there is <typically> a small rachet device , similar to an ascender, which is spring loaded to allow movement of the clew
"up" the rope but not down. A clew
,Typically, has a loop on th bottom side which is what you use to attach sandbags to.
I did a google search on clew
and couldn't find a picture of one. If I can find one in a stagecraft book
I'll post it for you. The above link is to a short article whisch discusses some of the coincendence between stage
rigging and sailing terminology. When theatres first started to be riggd in what we think of as "traditional" Sailors were tapped to operate them as they had the best command of rope rigging. Terminology therefore made the journey with these early sailors. This is where we get terms like "deck
" , Boom
, bay, etc
it is also where we get the superstition of "no Whistling backstage", on ships orders were often whistled up to the rigging since a whistle carries better than words in a squall. So when Sailors were working as flymen backstage you didn't want to be whistling for fear of winding up with a sand bag accidently dropped on your head, or inadvertantly cueing a scene change.
A Hemp fly system
is called a hemp fly system
because it is rigged with Hemp. The use of any other kind of rope could have disasterous results. Hemp is much more static than other ropes. In a hemp house
, you typically have five hemp ropes running to each batten
. It's not like a double or single purchase counterweight system
you might be familiar with. On a counterweight system
your hemp rope, or spectra rope, is only moving the arbor
up and down and the arbor
is connectedd to the batten
by 5 - 6 wire
ropes or cables. Since you keep the arbor
balanced with the load the rope doesn't really do any lifting, it only tilts the balance enough for the arbors wieght to kick in, or be over come. The cables on a counterweight system
are pre-set to desired lengths and is necessary you can lengthen or shorten them by means of the toggle-bolt
located on top of the arbor
or at the connectoin to the batten
. On a hemp system
each rope runs to the batten
individually. Imagine trying to pull evenly on all 5 ropes at the same time. the clew
helps distribute the down force of one rope to all the other ropes on a given lineset
that's where where the name comes from, a set of lines for each batten
> to all of the ropes.
On a Hemp system
the counter weights are sandbags suspended from each line
either by the clew
or a sunday
< I really want to know where the rigging term "sunday
" comes from. if anybody knows let me know> and therefore each hemp rope is exposed to much more stress than on a counterweight system
. Which is why it needs to be hemp not a synthetic.
Sorry for the punctuation and capitalization, I'm not use to my wifes laptop.
Hope that answers some questions and inspires you to do some more reseach about the history of theatre
. It's a really fascinating story.
