Black Rooster Weathervane

Black Rooster Weathervane-Caringbah NSW.

Hi Robert,
Our rooster is up on the roof.

The most important thing was to mount him at the back of our villa so I can
see him from inside the house.    He can still be seen from certain angles at
the front but as long as he doesn’t crow we wont have a problem.
The wind  has been flukey today, blowing SE and sometimes SW but he’s
working perfectly.
As you can see we have a difficult roof line to work with and the tiles
overlap considerably but the mounting block can’t be seen from the front and
gives him a little more height.               Many thanks, Helen and Ian.

Hi Robert,

I’m happy for him to go on your website .  He can be the “Mythical Caringbah Rooster” that

drives some of our locals crazy with his early morning crowing!!

Once again, many thanks.
Helen.

Sailboat Weathervane

The use of weathervanes dates back to ancient times when the first weathervane was used a temple in Athens. Since that time weathervanes have been produced and used in a variety of materials and portraying many different forms. One popular form is the sailboat weathervane which will discussed in further detail here.

The sailboat weathervane normally consists of a wind vane which is an unbalanced arrow shaped piece which rotates about a centre shaft. As the wind blows it rotates and aligns itself to the direction the wind is blowing at that time. Another piece is a fixed four quadrant wind direction indicator. By aligning these indicators properly, the wind vane will point to a particular quadrant so that the direction can be determined.

A very important part of most weathervane is the form which is added to the top. This gives the weathervane its distinctive look and has provided a great deal of customisation. For many years the common shape used on a weathervane was that of a rooster.

This happened due to a decree from the Pope and for hundreds of years rooster shaped weathervanes were placed on top of churches throughout Europe. The practice extended to many other structures throughout Europe and eventually followed to America.

In America many kinds of shapes were also developed for use as a topper for weathervanes. For a long time, political themes were important such as the eagle and Lady Liberty figure. During the 1800’s horses began to be used.

Since the horse represents strength, agility, and nobility these were popular items of choice. Since the direction of the wind was a vitally important factor in sailing ships, this theme was carried over by adding a sailboat shape to weathervanes.

For people who are interested in the sea and may be located in a nautical setting, this is a perfect addition to their primary or secondary homes. A sailboat weathervane can be obtained in a wide variety of sizes, colours, shapes, and materials.

Copper Weathervanes – A Brief History

The copper weathervane has been an important feature in most Australian homes and outdoor structures. It has evolved into a decorative item which can add years of beauty and functionality to your home. A little of its history will be discussed and reviewed.

The original purpose of a weathervane was to indicate the wind direction. However this device which is most commonly produced from copper or brass has evolved over the years. The first weathervane was installed on the Tower of Winds in Athens and was shaped like the Greek god Triton which was a half man, half fish figure.

The figure on this weathervane was four to eight feet long which is substantially larger than most weathervanes today. Throughout history, the copper weathervane has featured unique shapes.

The next major phase in the history of copper weathervanes featured a quadrant shaped wind vane with an animal or Norse fable creature on the top. These weathervanes were found in ninth century Viking settlements and on ships. However they can still be found on Swedish and Norwegian churches today.

For almost 1,000 years following a decree from the Pope, weathervanes were required to be installed on every church in Europe which featured a weather cock. This is a rooster shaped device which symbolised Jesus’ statement that the cock would not crow the morning following the Last Supper until the disciple Peter denounced him.

This helped to popularise rooster shaped weathervanes throughout Europe and eventually America. They are still a very common style produced to this day.

As it turns out the first weathervane used in America was a grasshopper shape and was placed on the top of Faneuil Hall in Boston. This figure was produced by the Deacon Shem Drowne who also designed a banner weathervane which was installed on top of the Old North Church as well as a rooster weathervane figure which was installed at the First Church in Cambridge.

Beginning in the early 1800’s weathervane designs featured many patriotic themes. They featured symbols of American freedom including the Goddess of Liberty and the American Eagle. The eagle copper weathervanes remain very popular in current times.

Other designs in the 19th and 20th century included racing horses as well as many figures created with a simplistic silhouette design. Throughout its history, copper weathervanes have remained the material of choice due to their good workability, strength, and corrosion resistance.

Windsock Fitting & Care

When using the cable ties to attach the windsock to the windsock frame, ensure that the cable tie’s ‘buckle’ is inside the rim to avoid the windsock material becoming damaged by rubbing on it. Once fitted, cut off the cable tie excess length.

Windsocks will not function correctly if the mouth is not vertical and facing into the wind.

The cable ties should be tight enough to restrict the movement, so that there can be no wear from rubbing of the windsock against the frame.

The windsock side seams should be at the 9 and 3 o’clock positions. (Along side each other, not top and bottom.)

To increase the life of the windsock, remove and rotate 180° after six months, then the following six months, remove the windsock again and turn inside out, re-hang with seams at the sides, then after another six months (depending on the condition) rotate windsock 180° again.

The above actions will more than double the windsock life.

Windsocks are not repairable, a torn windsock may give a false wind speed and direction.

Any windsock will perform at its best without any wind sheer influence from buildings, roof angles, trees, or orographic influences, so where possible consider placing the windsock at a distance greater than 25m from any other standing object, if this is not possible or practical, increase the height of the support as much as possible. Regulation height for a windsock is 6.7m (22ft) for 8 and 12 foot length windsocks.

This measurement is from the ground to the lower rim of the windsock.

This height requirement is not applicable to ‘Wind Indicators’ of windsock design and shape. There are 4 or 6 foot length (120cm and 180cm).

Windsock Material For 8 & 10 Foot

Windsock Material for 8 and 12 Foot Windsocks.

Made of compressed nylon, the windsock has the smooth side on the outside. When it gos through the rollers, it has the appearance of woven material, but it is continuous two sheets of compressed nylon. There are absolutely no gaps in the surface of the material.

It is self washing, and so this does not aid the adhesion of logos and sign writing, but sign writer plastic signs can adhere, but for how long? There are no guarantees.

There are 2 grades: Grade 3 and Grade5. (3 ounce/square foot for the standard windsock, and 5 ounce/square foot for the heavy duty windsock.)

One of the manufacturers is Canvaco.

The material is ‘Hot Needle Stitched’ and is also triple stitched.

The hoop, which is sewn in, is like grey electrical conduit.

The material does not stretch eg. Shirt material has a stretch factor of 4% and this materials’s stretch factor is approx. 1% – 1.5%.

Windsock Specifications 8 & 12 Foot

These are available in white, or yellow, and are also available in a choice of standard weight or heavy duty versions. the heavy duty version being for places of extreme wind, cyclone prone, or tropical areas.

The 8 & 12 foot windsocks are calibrated for Aviation use, fitted with an internal hoop and four large attach eyelets, and is supplied with heavy duty cable ties to attach to a 2ft diameter frame for the 8ft windsock, or a 3ft frame for the 12ft version.

The heavy duty windsock will outlast the standard weight by an estimated 50% under the same give conditions.

The standard weight windsock is slightly more ‘active’ in very light wind conditon.

12ft windsocks are the ‘standard’ for use at licenced and council airstrips and airports.

Windsock Stats

It is quite possible that there are several ‘primary’ windsocks at an airport, (one for each runway, and often one near the end of each runway.

Colour choice of windsocks for non commercial use is simply a matter of what stands out the best against the background colour as seen from the air. Yellow is easier to see against a background of sky, or as seen from the ground. Both colours illuminate well with the 12 volt lighting option, as the materials used have good fibre optic qualities.

8 & 12 ft Windsock Support Frames

These are made of 304, 316, 320 and 4000 grade stainless steel.

The 8 ft windsock frame has a 24″ (600mm) diameter rim, and the frame for the 12′ windsock has a 36″ (900mm) diameter rim. These frames may be fitted with internal 12 volt lighting…. See the”Windsock Illumination” section below:

Windsock Diagram

The sealed ball bearings, that are used top and bottom, should never require any lubrication or attention. The top bearing is also capped with a seal that is a tight press fit to the centre shaft, and offers further protection to the top bearing.

The base plate of the frame is a 10mm plate with studs at 50 & 80mm spacing, stainless washers and Nylock nuts are supplied for fitting either directly or via the “Welding Adapter”.

Welding AdapterAs the frame is stainless steel, (Which will not weld to ferrous metals.) thus the ‘Welding Adapter’ is recommended if the intention is to attach the frame to a metal pole end.

It is pre-drilled to match the frame stud pattern and base, made of malleable low carbon ferrous metal, that has been selected for ease of welding, using either gas, or electric arc methods.

The support frames are made for extra long life, and carry a 25 year replacement warranty. The same frames are also available (By special order) made from 316 grade stainless steel, and are ideal for offshore oil-rigs and other highly corrosive environments.

Windsock Illumination

Windsock illumination is available for the 8 and 12 foot windsocks. This operates from any 12 volt power supply, motorcycle or automotive battery, simply using battery clips or plug in using standard automotive cigarette lighter.

The lighting is 50 watt, halogen, and draws only 4 amps. (Less than a low beam headlight.) It is 100% reliable, and maintenance free. Solar charging, and remote switching are (add on) options. A spare 3000 hour life bulb/reflector is supplied.

Cable ties and spare bulb fuses

Cables and Ties as supplied in the lighting kit, including spare bulb.
