A lot of people assume that they must use furniture grade lumber for their woodworking projects. This kind of is not necessarily true. Construction grade lumber can be used as long as you follow a few simple guidelines. indonesia furniture
What Is The Difference?
Generally in most areas, kiln-dried construction level lumber sells for around 70 cents per thready foot. Now that is approximately half the price tag on furniture grade material, which can greatly reduce the organic material costs of any project. Most furniture quality lumber is harvested from pine, while most building grade lumber comes from spruce, jack pine or fir trees. While these are all considered softwood, they are surprisingly strong and dense.
If you inspect the boards carefully, you will notice that nearly all of them can actually be very high quality. It is not uncommon to find boards that are practically free from knots. Even boards with defects can contain portions of beautiful wood on both sides. Spruce can be particularly attractive launched quarter-sawn. This reveals their closely spaced growth bands, which has a very striking appearance.
You can produce high quality furniture from construction grade timber as long as you choose your boards carefully and handle it properly. Do not be deterred by minor damage or defects in the wooden. You will probably jet and join the solid wood anyway, so these minimal defects can be concealed or worked around.
Just how Dry Is Kiln-Dried?
The moment you hear the expression kiln-dried wood, you should believe that you are ready to begin your woodworking project, but try not to be fooled. For construction level lumber the term kiln-dried means that the wooden has less than even just the teens moisture. While this level of moisture is low enough to prevent the expansion of mold, it continues to be too moist to be applied for furniture building immediately.
The optimum wetness content for furniture building is actually between 6% and 8%, and so the wood will need to be dried further before it can be used effectively. The excess drying can be done once you get the wood home, when you leave the wood yard, ask about taking some of the slim wood strips that are employed to separate boards within the stacked piles. These types of will usually be free, as the lumber backyard will throw them away anyway.
Performing the Extra Blow drying
Once you get the wood home, re-stack the boards using the thin spacers you picked out up at the timber yard. It is extremely important the each table has got the maximum amount of area exposed to air. You will need to stack the wood in a completely heated, inside environment. A good time of 12 months to do this is during the winter a few months, as humidity will be the lowest.
To accelerate the drying process, place an oscillating fan coming on the pile. This kind of will vastly reduce the moisture content from twenty percent to 8% in about a month. Now this does not always suggest that you need to wait this well before working with the lumber. You may measure and cut the lumber for your task, just be sure that you do not plane, join or assembly the pieces until reaching the 8% water level.
