With Instructables you can share what you make with the world, and tap into an ever-growing community of creative experts. Before I begin with the actual instructions for building this model, I'd like to go over the process I use to mill wood for a model ship. The various PDF files that you downloaded are used as templates to make the various parts of the model. You will remember from the previous step that there was a scarf joint at the fore end of the keel. The final assembly of the keel structure is to add the sternpost as shown in the 1st photo and the stern deadwood as shown in the other photos. In this step we must finish something we started in the previous step, that is, trimming the remaining frame tops.
Some of the outer planking is Virginia holly, a very clear, white wood, as is the deck planking. Using Chappelle's body plan and waterlines, I was able to loft a set of frame drawings for my model.
There are several items I use regularly in my model building that constantly need replenishing.
Other items may be needed as we progress and I will try and give some advance notice of these items when they come up.
CAUTION: PLEASE READ THE INSTRUCTIONS THAT CAME WITH ALL OF YOUR POWER TOOLS TO UNDERSTAND THE SAFETY PROCEDURES ASSOCIATED WITH THE USE OF EACH TOOL. I have always wanted to build a Chinese Junk in this fashion and leave it half done so the intricacy can be viewed. In reinforced concrete construction, the combination of concrete and steel provides the three most important properties for earthquake resistance: stiffness, strength, and ductility.
Studies of earthquake damage consistently show well-anchored shear walls are the key to earthquake resistance in low-rise buildings.
Optimal design conditions include shear walls that extend the entire height and located on all four sides of a building.


Low-rise buildings most vulnerable to earthquakes do have the necessary stiffness, strength, and ductility to resist the forces of an earthquake or had walls that were not well anchored to a solid foundation, or both.
Most of these buildings were 3 to 4 stories tall with a parking garage or a living area with many large windows on the ground level. Wood-framed buildings are inherently ductile (flexible), which is an attribute during an earthquake. Masonry or concrete walls not reinforced with steel bars were not ductile enough to be effective shear walls. Reinforced concrete walls are a composite system: Concrete resists compression forces, and reinforcing steel resists tensile forces produced by an earthquake.
It’s no wonder that modern reinforced concrete buildings were found to survive these recent earthquakes with rarely any significant damage.
When children begin to learn about the concept of the solar system, understanding the galaxy and the fact that planets orbit the sun, can be a difficult and overwhelming idea to grasp at first.
Start by cutting strips of masking tape, and labelling one with “Sun” and the rest with the name of one planet each. Then, paint the individual balls of foam if you desire – this will make the solar system model more visually appealing.
Once this is done, proceed to label all the foam balls with their appropriate masking tape tags, according to the planets they will represent in the model. Finally, you may choose to attach a pin to the top of the Sun, and tie a string so you can hang the model up in a classroom, or your child’s bedroom. The October 22, 1887 issue of the Brooklyn Daily Eagle reported on the dastardly exploits of a muscular woman and her two-fisted henpecking.
It's a kind of tree that grows in various parts of the world and has virtually no visible grain and is very hard. You might also want to browse my website to see additional photos of my construction of the Hannah model as well as some other models I've designed in AutoCAD and buit from scratch. Long walls are stronger than short walls, and solid walls are better than ones with a lot of opening for windows and doors.


The columns may have been strong enough to hold up the structure, but did not provide an adequate amount of racking resistance during a seismic event.
And if there is no steel connecting them to their foundation, the joint between walls and foundation can be a weak point. The exceptional ductility of the steel to resist tensile forces, coupled with the rock-like ability of concrete to resist compression, results in an excellent combination of the three most important earthquake resistance properties: stiffness, strength, and ductility. However, concepts can be developed and their understanding can be boosted by helping them build a model of the solar system, which will explain the planetary system to them in a demonstrative way, in addition to proving a fun activity for the classroom or for home. Use yellow for the sun (the biggest ball of the lot), blue and green for the Earth, red for Mars, and so on. Additional information on milling the wood will be covered in the next step of these instructions. These elements are designed to survive severe sideways (in-plane) forces, called racking and shear, without being damaged or bent far out of position. When the earthquake shook the building side-to-side, the upper stories sometimes tipped over to one side. Whether built of wood, steel, or concrete—they all suffered damage. Frequently, the shear walls were strong enough, but the connection to the foundation was a weak point that gave way. A study at Construction Technology Laboratories revealed that even a lightly reinforced concrete shear wall has over six times the racking load resistance as framed wall construction. Repeat the same process with the rest of the skewers and balls, in accordance with the correct planetary order: Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. Shear walls also must be well anchored to the foundation structure to work effectively. Properly installed steel reinforcing bars extend across the joint between the walls and the foundation to provide secure anchorage to the foundation.
