Jarrah is one of Australia's best and most versatile woods in southwestern Australia and has been used in a variety of wood processing products since its settlement in Europe. Although Jarrah is hard, strong and easy to use, carpentry has discovered some of the challenges of wood and needs to know how to overcome them.
Unlike other Australian woods [such as blackwood or Queensland walnuts], Jarrah has no significant silica content, so the cutting blades do not wear excessively due to wear. However, due to the hardness of Jarrah, the cutting blades do tend to chip or chip. For cutting Jarrah, it is recommended to use well-tuned spokes or hand plates. You can use a high 30° bevel on the blade and keep it sharp. Well-tuned card scrapers work flawlessly, and experienced woodworkers get a beautiful tool look. #39;
Jarrah as a species shows a wide range of color changes over the length of the board. This can be from the darkness of the spot at one end to the clear light pink at the other end. Many large woodworking companies overcome this challenge by applying a layer of color on Jarrah to eliminate the difference and using paint to eliminate red and yellow. To ensure optimal color matching, ensure that the same source is used, which increases the likelihood that the board will come from the same tree from the sequence to achieve better color matching.
Woodworkers should also be aware that Jarrah has a unique texture that must match the particle type and color. It's easy to fall into the trap of two correct color but wrong texture boards. If the backpack and the quarter board are freely mixed in one package, this situation may be exaggerated. When receiving a new stock, a good idea is to gently slap the best side of the planer and write the code on the shading. The boards can then be stacked depending on whether they are quarter or post saw.
Most carpentry knows that Jarrah reacts very strongly to direct sunlight and turns into a powdery yellow when exposed to strong light. Jarrah furniture should have only scattered natural light, suitable for bedroom furniture. Woodworkers should also be careful to paint because the paint seems to accelerate fading and make the fixed discoloration more serious.
For joinery, woodwork should not make the joints too tight. Jarrah is compressed in the same way as soft wood. For example, in a blink of an eye with a cheek close to the cheek, if the joints are forced together, the blink will separate along the texture above and below to accommodate the hoe. Woodworkers that make furniture such as chairs with small parts are particularly difficult to find.
Careful color matching, covering the work between sessions, the correct installation of joinery and the use of some additional coatings, carpentry can overcome the challenges of working with Jarrah. Make sure these are carefully considered and working with Jarrah is an experience that few other woods can offer.
