a balsa tree may grow to a diameter

The logging team usually consists of two native Ecquadorians, each armed with a broad Spanish axe, a machete, and a long pole sharpened like a chisel on one end for removing the bark from the downed trees. Because of the hilly terrain, an ox team may only be able to drag two logs to the river per day. At the saw mill, the balsa is first rough cut into large boards, then carefully kiln dried, and finally packed into bales for shipment to the U.S. via ocean freighter.
Balsa trees grow very rapidly (like all pesky weeds). Six months after germination, the tree is about 1-1/2 inches in diameter and 10 - 12 feet tall. In 6 to 10 years the tree is ready for cutting, having reached a height of 60 to 90 feet tall and a diameter of 12 to 45 inches. If left to continue growing, the new wood being grown on the outside layers becomes very hard and the tree begins to rot in the center.
Unharvested, a balsa tree may grow to a diameter of 6 feet or more, but very little usable lumber can be obtained from a tree of this size. The basla leaf is similar in shape to a grape leaf, only a lot bigger. When the tree is young, these leaves measure a much as four feet across. They become progressivly smaller as the tree grows older, until they are about 8 - 10 inches across. Balsa is one of the few trees in the jungle which has a simple leaf shape. This fact alone makes the balsa tree stand out in the jungle.
Final cutting and finishing of our model aircraft balsa is done right here at the SIG factory. As a result of the balsa tree's fast growth cycle, both the quality and lightness of the lumber obtained from a balsa tree can vary enormously depending upon the tree's age at the time of cutting.

Which Hardwood to Choose?

Varieties of hardwood lumber are the staple materials for the woodworker, particularly those who focus on fine woodworking projects such as furniture. However, the term hardwood can be a bit deceiving, as it has less to do with the "hardness" of the material than the species of the tree from which the lumber is harvested.Here to know more about balsa wood, which is the softest wood in the world.
Hardwoods come from deciduous, or broad-leaved trees, as opposed to softwoods, that are harvested from from evergreens. In general, hardwood species are typically harder than softwoods, although there are exceptions (balsa wood is very light and soft, but is considered a hardwood). Most hardwood tree species lose their leaves in winter, and generally offer a much wider variety of colors and textures than softwoods.
Which Hardwood to Choose?:
When preparing to build a project, the choice of which hardwood material to use can be a daunting question. To make it easier, start with determining how you want to finish the project. Will you stain or paint it?
If you choose paint for your finish, you won't want to waste your money on woods known for their color and beauty when stained, so avoid richly-colored species such as oak, maple, walnut or mahogany. For painted projects, poplar would be a much better choice.
However, if you want to stain or clear-coat the project, you'll have a number of choices to look through. Since your local home center megamart will probably only carry a couple of hardwood species (poplar and red oak are common) spend time at a fine wood supplier and look through the vareties available. They should be able to help you determine how each species will look when finished, which will go a long way toward refining your decision.
Location, Location, Location:
In addition to the type of finish you want, the location of the final installation should be considered when choosing a hardwood species. While it won't have as much bearing on furniture pieces to be used indoors, you may want to consider some more moisture-resistant species (such as cypress or the ever-increasingly endangered teak) for outdoor projects. Again, your local woodworking supplier will be able to help with this decision.

one of the leading suppliers of balsa wood

Do you believe that balsa wood have been used for cork, surgical splints, insulation, life belts, floats and toys during World War II? Well, balsa wood is well known among consumers for lightweight, soft and easy to work with. Balsa wood is available in 3 grain patterns depending on the cut, like A grain, B grain, and C grain.
Generally, A grain has long grain lines and it is cut on a tangent. It is the ideal choice for model plane fuselages since it is easy to curve and bend. It is easy to warp since it has long fibers. B grain balsa wood is medium and slightly stiffer and it is random cut. It can be used for multipurpose parts. C grain is quartersawn, mottled and the most stiff one. All in all, balsa wood is easy to cut, shaped, sanded, fzbmcihlwd glued, routed and painted. It is easy to work with thin-edged hand or power tools actually.
Balsa wood is usually used for making models, like model planes, gliders, houses and so forth. You can cut the thin balsa sheets easily with a utility knife. Balsa tree grows on plantations, eliminating the need for laborious cutting and hauling of single trees out of old-growth forests. It grows quite rapidly. Unlike other hardwoods, balsa wood cells are fatter and contain more water. Only 40 percent of the wood is actually solid since it contains less lignin.
As we have introduced in our previous articles, balsa wood belongs to hard wood though it is soft and easy to work with. It can be regarded as the most light and soft hardwood in the world. Balsa wood can be found easily both in domestic and international markets. You can buy it from physical stores and online shops. You are advised to choose a reliable supplier actually.
Frankly speaking, Shanghai Synhong is one of the leading suppliers of balsa wood. We provide various kinds of balsa sheets, balsa blocks and balsa products. We have great reputation among consumers both at home and abroad for high quality and competitive price.

hardwood is usually stronger than softwood

There has a unique resource in its native hardwoods, producing some of the most durable and attractive timbers in the world. Native hardwoods are sourced from managed forests and more recently from plantations and farm forestry. Australia also imports a number of hardwood timbers from overseas.If you are also intereted in balsa wood, you can go to our website.
The distinction between hardwood and softwood is botanical, rather than referring to the strength or hardness of the wood. Hardwoods are relatively broad-leafed trees with seeds that are produced in an enclosed form, such as a fruit or nut; softwoods are coniferous or cone bearing trees with needle-like leaves. Due to a higher density, hardwood is usually stronger than softwood but this is not always the case; for example, balsa is a hardwood and white cypress is very strong softwood.
Hardwood timbers are ideal for high strength structural applications, such as bearers, joists, lintels and roof beams. The natural durability of most hardwoods also makes them perfect for external applications, such as decking and cladding, and for interior flooring and stairs. Hardwood timbers are also highly recyclable due to their long above-ground life, with some of Australia’s indigenous hardwood species, such asczmcihlwd  jarrah, blackwood and red gum, much prized for recycled flooring, panelling, furniture and landscaping.
To find the right timber for your project, search hardwood species using botanical name, common name or applications.

You have to think about a lot of details of the woods

Whether you see woodworking as an art or a craft, your finished piece begins with a great piece of wood. As a woodworker, buying wood can be a challenging experience. You have to think about a lot of details such as the grade and cut of the wood and the way it's sized. The following sections help you make sense of these details.You may also want to know the info about the softwood balsa . Here to know more.
Take a pencil, measuring tape, scrap paper, small block plane (to check out the color and grain) and a calculator to the lumberyard and write down all the dimensions and total board feet for each board. This way you can double-check the salesperson's calculations and make sure you aren't overcharged.
Wood grades
Wood grades refer to the number and severity of the defects in a board. The following list explains the different wood grades, according to the National Hardwood Lumber Association (or NHLA for short).
Firsts: Very few, if any, noticeable defects.
Seconds: The occasional knot or other surface defect. Firsts and seconds are often grouped together and referred to as FAS (firsts and seconds). These are the grades you want for furniture building.
Selects: A few more defects, but nothing so big or frequent that it can't be cut out. Avoid this grade for fine furniture, though, because it adds more work to the process.
Four grades of Common (#1, #2, #3a, #3b): Too many defects to use for furniture.
Types of wood cuts
How wood is cut affects its quality. The following list explains the types of cuts:
Plain-sawn: The most common boards at your lumberyard. They have growth rings that run less than 30 degrees against the face of the board. The face grain looks somewhat circular and wavy.
Rift-sawn: These boards have growths rings that meet the face between 30 and 60 degrees. Rift-sawn boards have a straight grain pattern as opposed to the circular pattern of the plain-sawn boards. They're also more stable and more expensive than plain-sawn wood.
Quarter-sawn: These boards have growth rings not less than 60 degrees from their face and a straight grain pattern with a flake or ribbon-like figure in the wood. Quarter-sawn boards are more stable and expensive than the other types of boards and you can only find them in a few species of wood, such as white oak.
Wood defects
It's okay to buy wood with knots, splits, cracks, and checks. These defects affect only a small area of the board (if they exist over the majority of the board, don't buy it), so you can plan your cuts around them. Avoid boards with warps, twists, or bows. It takes a lot of time to flatten a board that has one of these defects. To test for these defects, place one end of the board on the floor and hold the other end to your eye. The board should be straight and true. If not, leave it there.
Sizing up the wood
Wood is sold two ways: dimensional and by the board foot:
Dimensional wood is smooth on all four sides, cut to precise widths and thicknesses, and is sold by the linear foot or the board.
Wood sold by the board foot may or may not be smooth on all sides and only one edge may be square. A board foot is a board that is 1 inch thick (called 4/4) by 12 inches wide by 1 foot long. To figure out how many board feet are in a piece of wood, multiply its length (measured in feet), width, and thickness (measured in inches) and divide this number by 12.

a Type of Flexible Wood Strips - Balsa

Technically speaking, there are few types of flexible wood strips which could be used to make models. For example, the balsa wood is always considered as the most popular flexible wood strips. If you are planning to start your hobby making career, you should better start from the balsa wood . Especially while you do not have too much experience, the balsa would provide you the chance to make the project easier.
Balsa is popular for its flexibility. It is so flexible that while you applying it to the production process of models, you would cut, assemble and glue the balsa strips much easier. In addition to the flexibility, the stability is another reason for its popularity. Of course, the stability is relatively better as compared with other types of wood, when it comes to the steel, the wood would not be stronger.
Frankly, the steel wire is much easier to be bent and it is much stronger than the wood. In some types of the balsa model, the steel could be used as the frame. Generally, the steel wire could not be singly to make models, but in some situation, the steel wires could be bent by skillful workers to make series of products, such as bikes, towers and bridges.
For both the beginners and even for the skillful makers, without doubts, balsa wood should be their favourite material. For the experienced makers, they could choose the different types of balsa wood to work for the different parts of their models. You should know that even for the same types of woods, they are born with different densities. The heavier could be used to bear more pressure.
Even more, the veteran makers could mix different types of materials in their project. They could choose the metal to make the base of the model, some stronger wood to make the frame and the balsa wood to form the appearance. They need to choose various materials to insure the connection between different materials. In summary, the balsa woods are the favourite flexible wood strips. If you want to attain a perfect project, you need to use different types of materials together. .For more, if you are also interested in balsa rectangle , you can go to our website to know more.

Is Hardwood Firewood Really Better Than Softwood For Wood Stoves?

Hardwood firewood, in many parts of the world, is the most sought after type of firewood compared to softwood. Is hardwood really that much better and is there really a noticeable difference between the two?For more, if you want to know more about the softwood balsa, then you can take a look into our website. You know that the balsa wood can make your different kinds of model.
There is a difference between the way some hardwoods and softwoods burn. I say some g4nmkvkz hardwoods because there are some hardwoods that burn more similar to softwoods. The biggest difference between the two is the density. Many hardwoods like oak and hickory are much more dense than softwoods. But some hardwoods like cottonwood, alder and aspen are more similar to softwoods in density.
High density hardwoods that are considered by many to be the best firewood, are some of the most dense woods. This means there is more actual solid wood in any given sized piece. Since there is more actual wood in dense hardwoods, they also produce more energy and burn longer than less dense softwoods. For heating a home with a wood stove this makes hardwood a good choice since the wood will last longer and produce more heat over a long time.
Softwoods and low density hardwoods are more porous and have less wood for any specific volume. This less dense and more resinous wood is actually easier to ignite and burn. Softwoods are more likely to burn with more intense flames and put out heat faster than hardwoods. Because of this and because it easily splits into small strips, softwood makes good kindling. When you want to get a hot fire fast softwood is usually better than hardwood. But don't expect it to last long since it burns up fast.
Softwood is great for starting fires and building hot fires fast. Hardwood is better for putting out more steady heat over a longer amount of time. Hardwood is not necessarily better, it's just different. They both have advantages and disadvantages and both have their place in wood heating. I prefer to have both on hand so I can have the best of both types.Here to know more about end grain balsa , article resource: http://www.balsafactory.com/.

numerous uses of the Yellow Poplar wood

Tupelo, Water
Water tupelo (Nyssa aquatica), is a large, long-lived tree that grows in southern swamps and flood plains where its root system is periodically under water. It has a swollen base that tapers to a long, clear bole and often occurs in pure stands. A good mature tree will produce commercial timber used for furniture and crates. Many kinds of wildlife eat the fruits and water tupelo is a favored honey tree.For more if you interesed in the softwood balsa , you can take information in our webiste.
Walnut, Black
Black walnut used to be a very common old-growth forest tree. Black walnut wood is now relatively scarce and highly coveted, used mainly for high quality woodworking. The tree hates shade (intolerant)and best growth occurs in a sunny open location and a moist rich soil, common along stream banks in its native habitat.
Willow, Black
Black willow is named for its dark gray-brown bark. The tree is the largest and most important New World willow and is one of the first trees to bud in the spring. The numerous uses of the wood of this and other willows is furniture doors, millwork, barrels and boxes.
Yellow Poplar
Yellow poplar or tulip poplar is the tallest hardwood tree in North America with qyexbictzs one of the most perfect and straight trunks in the forest. Yellow poplar has a very unique leaf with four lobes separated by rounded notches.

Information for elm and dogwood

Dogwood, Flowering
Flowering dogwood is one of the most popular ornamental landscape trees in eastern North America. They are usually displayed beneath large oaks or pines, both in the wild and as an ornamental. Dogwoods are among the earliest springtime blooming trees. With its dense crown, flowering dogwood provides good shade, and due to its small stature, it is useful in the smallest yards. This beloved tree is the state tree of Missouri, North Carolina and Virginia.For more if you are interested in balsa  wood (balsa tree), you can visit our website.the quality bass polywood is for you.
 Elm, American
American elm has long been very popular as a street or avenue tree but never really took to parks and cities. It is now being replaced by better trees like London plane-tree (Platanus X acerfolia) and Japanese zelkova (Zelkova serrata). Once extensively planted as a shade tree, Dutch elm disease has killed many of these. Isolated trees seem to be less susceptible to the disease while mass plantings tend to exacerbate the problems. American elm is of little value as a forest product.
Elm, Rock
Rock elm or cork elm, is a deciduous tree native primarily to the Midwestern United States. The wood is the hardest and heaviest of all elms. It is also very strong and takes a high polish which offers a wide range of uses, notably shipbuilding, furniture, agricultural tools, and musical instruments.
 Elm, Slippery
Slippery elm is reputedly less susceptible to Dutch elm disease than other North American elms but is severely damaged by the Elm Leaf Beetle. Slippery elm is one of the smallest native North American elms but with one of the largest leaves. The tree never grows in pure stands. The tree has a slimy (slippery) inner bark, tastes like licorice and is has some food and medicinal value.

Information on Balsa Wood

The balsa tree, with its scientific name Ochroma pyramidale, is an evergreen tree native to South and Central America, and grows as far north as Mexico. These hardy trees can grow in difficult conditions. They tolerate drought, thin or rocky soil, harsh sunlight and are evergreen in most of their warm native climates. Balsa wood, from the balsa tree, is known for certain specific qualities.
Age
Balsa trees have a lifespan generally around 100 years. Thus, as opposed to oak, redwood or maple, balsa wood is a relatively young wood.
Hardness
Balsa wood is technically considered to be a "hardwood." However, it is the lightest of all pxbkctbsd hardwoods, with an open (as opposed to dense) grain structure.
The Name
The word "balsa" is derived from the Spanish word for "raft" and, in earlier centuries, balsa wood was indeed used for raft building.
Strength
In spite of its lightness, balsa wood is also strong, which is an odd combination in the hardwood family.
Uses
Balsa wood is used in the boating industry. It is a common wood for model building. It was also used in the early days of airplane building and used to make small planes that were both light and strong.

What is Pound Balsa?

What is Contest 4 to 6 Pound Balsa?
Contest Balsa is nothing more than balsa that should fall within 4 to 6 pounds measured by density in pounds per cubic foot.
But all you really need to do is to think about the application area of your model, especially when you enlarge plans or build larger aircraft. An investment in a nice electronic gram scale will be a big help. The chart below is a great reference for wing sheeting which can be applied to other areas of your model building. If the hobby store doesn't mind, bring your gram scale with you when you purchase balsa for your next project so you can build lighter, larger and stronger model aircraft.
Balsa Grains
A-Grain: Balsa sheet has long fibers that show up as grain lines. Its very flexible across the gdjlhqgnvz sheet and bends around curves easily. Watch-out it warps easily.
B-Grain: Balsa sheet has some of the qualities of both A & B grain. Grain lines are shorter the A and feels stiffer across the sheet. It is a general purpose selection and can be used for many different jobs
C-Grain: Balsa sheet has a mottled appearance. It is very stiff across the sheet and spits easily. Great for wing ribs and light formers. When used properly, it will help you build a light yet very strong model. Four to Six pound balsa stock is commonly called "Contest Balsa"

C grain balsa wood features

balsa grading is done based on the orientation of the cells in the balsa. Balsa has two main types of cells, longitudinal and radial. As the tree is standing, the longitudinal cells are vertical, and the radial cells (or rays...) are horizontal, from the center of the tree out. In the picture below, the longitudinal cells appear as dots, and the rays appear as lines.
Grading balsa has been done in the same way for over 60 years. The standard designations of A, B, and C have been use to describe the grain orientation of the cut sheet, and a view of how the sheets are cut from the balsa billet are shown below. (Note that the rectangles with the grain designations would represent the -end- of a balsa sheet...)
A grain is that which has the longitudnial cells running the length of the sheet, and the rays perpendicular to the sheet. A grain is generally used for wing spars and outlines, and is more readily bent around forms for wing tips. Note in the picture below you can see the long darker cells, which are the longitudinal cells. This contributes to the stiffness over the length of the sheet, and why it is suited well for spars. A grain sheets, due to the orientation from the original log, generally have a high degree of uniformity from the sheet, since all of the width of the sheet came from the same growth cycle of the tree. A grain is also very flexible across the width of the sheet, and stiffest along the lenght of the sheet.
C grain has the rays oriented across the width of the sheet, and a "perfect" sheet of C grain should look like this:
Note that you can see the rays traveling virtually the entire width of the sheet, which contributes to the stiffness. C grain is generally used for ribs, motorsticks, and booms, and is very stiff when rolled into tubes. C grain is somewhat like a natural plywood, due to the orientation of the longitudinal and radial cells, and has charistics of plywood in that respect. As a billet of balsa is being cut for C grain, due to the nature of the growth rings, axtmdjbfzx the billet will eventually not be "perfect" C grain. In the picture below, you can see a sheet cut which is typically considered C grain, but is a few degrees from a true C grain sheet.
As the sheets diverge from being cut along the rays, the sheet takes on a more mottled apperance instead of distinct wide lines, and eventually turns into B grain.
"Mottled" C grain and BC grain can many times be used as effectively as "perfect" C grain. In fact, some actually prefer BC grain for some applications, as when a tube made from it does break, it can be easier to repair. Grading of balsa is obviously not a science, and many sheets could fall into either category, but generally the predominate characteristic of the sheet will be used for the final grading.
In any given billet, you can theoretically orient the billet to get any of the above grains. However, some billets are more suited to one grade or the other, and generally sheets are cut in the orientation that is most efficient and has the highest yield. As you can see in the above picture, a billet oriented with A grain on the top would not need to be rotated during the cutting process much if at all, and all sheets would basically be "perfect" A grain. Balsa stock generally comes in 3"x3"x36" blocks, which then are cut in two, (for the standard 18" sheet length") and then each block is sawn in two, with each billet measuring approximately 1.25"x3"x18".
It is almost always possible to orient a 3"x3" block to get perfect grain orientation, but since low density balsa stock is in fairly short supply, and in the attempt to get the highest balance of yield to quality, some billets are cut "as is" instead of cutting them up to get a perfect billet. In other words, given a block of good 4# balsa, it is better to have two billets than one, i.e. twice as many sheets. This is where the in-between grades of AB, B, and BC generally come from.
During the cutting process, my setup allows me to angle the billet to optimize the grain orientation. However, on each change, the billet has to be squared off before the cut, resulting in waste and less yield. Depending on the particular billet being sawn, this may or may not be desireable. Due to the lower yield when cutting sheets graded as either AP or CP ("perfect" A or C grain) are priced at a slight premium.If you want to know more information about balsa wood, go to our website here : http://www.balsafactory.com/.

Cut the balsa wood into the shapes

balsa wood is a soft, spongy wood that's prized for being so light that it can be cut using a craft knife rather than a saw. In some cases, however, the softness of this wood make it problematic for structures that need a little more strength. Combine the best of both worlds by hardening your balsa wood pieces after they're cut or adding strength through double panes of reinforced wood.
Cut the balsa wood into the shapes you want for your project; this way, you can get the pieces you want with ease while the wood is still easy to cut.
Pour wood hardener into the disposable container. Fill it deep enough to submerge the thickest piece of balsa wood you've cut.
Submerge each piece of wood in hardening solution using the tongs (do them in turn, or all at once, depending on the size of the container), coating them completely. Hold each piece of wood under the liquid and watch bubbles rise from the spongy wood. Remove each piece when it no longer bubbles and cannot soak up any more hardener.
Lay the wood pieces on waxed paper. Let them dry according to the instructions on the wood hardener, allowing each side of the wood to dry for the allotted time before turning it over to let the other side dry for the same time.
Cut two pieces of balsa wood for each piece of your craft project. With each pair of axtmdjbfzzc pieces, cut the second one so that it mirrors the first, allowing you to press the two pieces together back-to-back.
Using the paintbrush, coat one of each pair of pieces with epoxy resin. Use a thin coat, but try to cover the entire piece. If the wood is too big or the resin too thick to cover the whole thing, apply epoxy in a line around the outside edge of the wood.
Glue the two pieces of wood together. Press each piece of wood against its matching piece, lining up their edges and pushing them firmly together. Hold the wood pieces together until the epoxy sets, or lay the wood on its side to let gravity hold the pieces in place.For more related article comes from http://www.balsafactory.com/.

different types of rc airplanes

You can easily make RC airplanes by yourself. balsa RC Airplane kits can be of different types. The prominent ones are:
1. RTF Kits:
Ready-to-fly (popularly known as RTF) RC airplane kits contain all the pre-assembled parts together and require a relatively less amount of assembly work. With these kits, one can construct a remote-controlled airplane in just about an hour.
2. ARTF Kits:
Almost Ready To Fly (ARTF) Radio Controlled Airplane Kits are somewhat similar to RTF kits kxiugtka but require relatively more time for assembly and basic construction. On an average, it takes around 20 hours of labor when assembling an aircraft using Almost Ready To Fly kits. These kits will require separate both purchase as well as installation of servos, speed controller (electric), choice of motor (glow fuel, gas or electric) and occasionally control rods.
3. From scratch or plans:
Radio-controlled airplanes can even be constructed from scratch or plans. Many plans are available in the market. These plans include an Radio Controlled airplane's complete drawing and also its components. The parts first need to be cut as per the shape and size mentioned in the fuselage and in the plan. The rest of the steps are similar to that elaborated in the pre-assembled kits wherein all the essential components are assembled and joined together to build an RC Airplane.
To building Radio Controlled Airplane from scratch involves significant knowledge of airplane design. Constructing Radio Controlled Airplanes from scratch can be a very fun and delightful process.
4. Balsa Kits:
Balsa RC Airplane kits are available in a range of sizes and skill levels. These kits usually contain most raw materials that are required for building an unassembled airplane. Balsa kits can be of two types, namely laser cut Balsa kits and die-cut Balsa kits. Laser cut kits are comparatively more expensive and have more accuracy and tolerance in their construction. Balsa R. C Airplane kits don't usually include the essential tools which can be bought separately.
We all know that balsa wood is the best wood for our models. but where to get those quality balsa  with reasonable price. Here i highly recommend you a professional online store for the website is http://www.balsafactory.com/.

Balsa wood is an ideal material for making model airplanes

balsa Wood is kiln-dried and industrialized to obtain End-Grain Balsa Core Material, muxtpvix which is used in many different applications that require to be lightweight but still with high performance. These industries are: Aerospace, Marine, Wind, Transportation, Tub & Shower, Flooring & Panelling and Construction. Balsa Wood is also vastly used in the Model Grade industry to make model aircraft and other model equipment. Another large application for Balsa Wood is the surfing industry.
Balsa wood is an ideal material for making model airplanes. Balsa is light, strong, affordable, easy to shape and readily available. Balsa wood has been a principle construction material for model aircraft since the 1930s and remains so today. Following are eight interesting facts about this remarkable building material.
For any aircraft, from a real world Boeing 747 to a micro indoor radio control model plane, an important factor for successful flight is low weight. The less an aircraft weighs the better the flight performance.
Once the goal of low aircraft weight is understood, it is easy to understand why balsa wood is such a popular model airplane building material. Balsa wood is lightweight, readily available and has an exceptionally high strength-to-weight ratio. Balsa can be cut, sanded and shaped with everyday hand tools. Balsa absorbs shock and vibration well, and accepts a wide variety of glues and paints.More related article comes from http://www.balsafactory.com/.
