    two. Tie Rigging Telltales onto Shrouds and Stay

    Use shroud and stay telltales on an instant at-a-glance apparent wind indicators. They can be easier for the person on the sailboat wheel or tiller to check out than headsail luff telltales. Cut one 9" and two 7" pieces of yarn.

    Tie the 9" yarn onto your backstay and the two 7" sections onto each upper shroud. Install them at least 6 feet off the deck. sail makersSandpits (also known as sandboxes) are an important part of many playgrounds, and can provide hours of imaginative and constructive enjoy activity. If this is the case in your playground, then you will have to resort to the tried and tested method of the wheelbarrow and shovel.

    Step 2. Design

    Your design should consider easy training access for users. Preferablly the sandpit walls will be sunk entirely into the ground, or be constructed with low entry spots to provide easy access. Ideally, sandpits should have a flat lip around their perimeter. This can be utilized for seats as well as providing a flat surface for playing with toys in addition to a shelf for building on. The lip should be clearly defined and easily seen so that it will not become a potential excursion hazard. It also serves to provides an easy sweep area, for sweeping stocked full sand back.

    Materials

    Sandpits usually are constructed from timber, concrete, pavers or brick blocks depending on what material is most effective the site. If you use timber, be careful not to use timber containing been treated with CCA (Copper Chromium Arsenic). Ask your supplier for alternative treated timber including ACQ or use hardwoods.

    Covering the structural component of the sandpit with wet pour rubber is the ideal solution to providing safe edging, although synthetic grass may also be used. When designing your sandpit ensure that edges are rounded or at the least bevelled, to reduce the potential with regard to impact injuries.

    Drainage

    Drainage is another important factor to prevent your sandpit from becoming a swimming pool in times of heavy rain. Furthermore a well drained sandpit means that the sand is washed and freshened with the rain, resulting in more hygienic sandpit. 150mm of loose rocks or aggregate should be used at the bottom of the sandpit to prevent water build up and can be used to drain away the water. You will need a barrier between the sand and also the drainage rock material to prevent children digging down to the rocks. The barrier should become of a porous material such as geotech fabric, rubber or perforated man made grass.

    Step 3. The Construction Process

    After you have your design, you can either construct the sandpit yourself, or outsource the project to a professional tradesperson. Landscapers, building firms, concreters, carpenters or playground specialists are where to start your enquiries depending over the scope of works. Ask around at other commercial playgrounds and obtain recommendations from operator who can recommend a tradesperson from a similar project. Ideally your chosen company will need to have a track record in similar assignments.

    When you are obtaining quotes, provide a plan or sketch of your design and a written list of your criteria. This will ensure that everybody is quoting on a single specifications.
