storing-green-wood-for-turning-zero Learn how to properly store and turn unseasoned wood with this woodturning article by Dale Nish. Unseasoned Bowl Blanks. Timber is very difficult to dry in thick pieces, due to the length of time involved and the fact that in order to reduce cracking, the wood inside the block needs to dry at about the same rate as the outside of the block.  Good instructions. I have found that the green turned bowl can be remounted usually on the opened jaws of the chuck (no plate) and the live center in the dimple of the original tenon to correct the tenon. Larger or deeper bowls will require using a shaft extension or a plate for the additional depth. Woodturning-Live-Edge-Bowl-Pecan-Green-WoodIn this video I will share with you a green wood turned live edge pecan bowl from start to finish. You will see. Learn how to turn bowls from green wood or seasoned wood bowl blanks.  The answer is, both green wood blanks and seasoned blanks can be great for bowl turning.

Turning green wood bowls is one of the most satisfying experiences imaginable. Taking a freshly cut piece of timber and turning stlring into a form, a creation to enjoy, use, and admire, is the ultimate gratification. Wood is an ever-changing, dynamic material. Raw timber, green wood, is the blank canvas of bowl turning.

And as woodturners, we need to understand this dynamic stoding to harness its possibilities and not become surprised or potentially humiliated by its realities.

It is up to us to apply our vision to see the potential that lies in each grain-filled specimen and bring it to a new life as a functional or decorative turned piece. There are two broad categories of bowl blanks, green or wet wood and dried bowl blanks. Storing green wood for turning zero green wood is not without its drawbacks and quirks. Before we go too far, it makes sense to define green wood. Some people, define green wood as only freshly cut wood grwen comes from a recently growing living tree.

That type of green forr is usually dripping with moisture, especially if harvested in the spring or summer months.

Any wood that stkring not seasoned and noticeably moist is considered green wood. This may be wood grren a just fallen tree or a log that has sat for some time. Wood can hold moisture for very long periods of time after being cut or downed. This may sound silly, but virtually any wood that is wet and not dry is green wood.

Wood that can still lose excess moisture is green wood. With either the passage of time or the use of a kiln, wood is dried or seasoned. When the amount of moisture in a particular piece of wood is reduced to the point where no more moisture can be moved out of the log, this constitutes dry wood.

A rule of thumb that is thrown around often is qood year of air drying time per one inch of wood thickness. A dryer or kiln can be used to reduce the moisture content more rapidly.

Another alternative, a microwave can aide in this process by methodically heating the wood-locked moisture which forces it to escape in the form of water vapor. Did you notice the definition of dry wood above? Why is this? Everything everywhere is relative. Wood is somewhat like a sponge. It will absorb and release moisture forever. Yes, I said forever.

Some woods do an excellent job making us think they are not moving and shifting because of moisture content, but they Storing Green Wood For Turning Vale are. The cells in wood continue to absorb relative humidity in the air, and they also secrete storing green wood for turning zero when the surrounding relative humidity is low. Wood is a dynamic changing material that can be turned and made into beautiful creations, but we need to storing green wood for turning zero mindful that it is not a static, fixed material.

Moisture levels in wood are subject to change with the surrounding climate and conditions. But there are many indicators that we can use as guides along the way. Moisture in the wood cells helps define the shape of those wood fibers. And storing green wood for turning zero fof form of those cells can be changed, the entire chunk of wood can, therefore, be changed as well. This movement can be subtle or dramatic. When the timber is cut, the tree can no longer move moisture the way it did when it was living.

Basically, a cut piece of wood is exactly like a kitchen sponge. If a kitchen sponge is wet, it expands and fills its cells with water. The same kitchen sponge left on the counter to dry will contract, shrink, and pull together in a tightly curled shape.

Expanding and contracting is essentially what wood does as well, forever. The worst offender when turning green wood bowls is cracking. Cracks occur when the internal pressures in the wood structure dry unevenly. A bowl wall that was turned thin at the rim and thicker at the base cannot move moisture in and out evenly.

This stress between too uneven regions usually causes cracking when the bowl is left to dry. Cracking occurs based on the organic structure of the tree and the different areas in the log under various pressures, as well. The pith area of a log tuening especially prone to cracking. All the surrounding wood layers pull and push from this core. Even and consistent wall thickness when turning green wood is the key to reducing the chances for cracks.

While the pith can be left in a green wood bowl turning, it really needs to be carefully handled. I would suggest positioning the pith, if left in the bowl, down the side of a bowl and not along the rim edge. The most important aspect of green wood bowl turning with or without the pith is to make the bowl walls even throughout. As the kitchen sponge image above illustrates, the shape of a green wood bowl turning will change as well. It is merely the nature of working with green wood.

Do not have unrealistic expectations of a perfectly round-rimmed final bowl. That is not what happens when turning green wood bowls. A simple round turned traditional bowl will most likely elongate a bit and distort as it drys. Usually, the rim will have elevated areas that form near the pith on each side of the bowl rim. This is the natural movement of the wood grain as it drys. Turning green wood bowls relatively thin can cause warps, waves and dancing wood during and after the drying process.

This is all part of the fun of green wood bowl turning. To add to the unpredictability of turning green wood bowls, each tree species behaves differently than one another. For instance, cherry can be super finicky and is ready to crack storing green wood for turning zero you look at it wrong. While hickory is usually rock hardwood that can be shelved for years and turned tutning free usually.

Each species of tree grows, forms, and develops differently. For example, the Eucalyptus is said to pull microscopic grains of soil with silica into its cells as it grows. Each wood species is different and will behave differently. Green wood is genuinely satisfying to work with. Long curling shavings glisten with moisture and fall to the floor leaving little storing green wood for turning zero no dust. At times the wood seems to cut like a bar of soap, effortless and smooth.

It is important to remember the characteristics of this wet wood. The green wood can be spongy, and there are particular things to consider while turning. If you are like me and you have many different growing timber species available in your local area, consider conducting this experiment the next time you land a pile of turnable wood. Take an available log of one species, ideally one that is typical Storing Green Wood For Turning 04 and average from a pile of similar logs, and make several bowl blanks.

On the lathe, turn sample bowls to determine how the green wood will behave. Turn a thin walled bowl, a medium thick walled bowl, and a thicker bowl. Let the bowls air dry or place them in paper bags with fresh shavings. What happened to each of the different bowls? Did cracks form, and if so where were the cracks? Did the wood move, warp, wave, or deform, and which thickness bowl moved the most? Turning green wood bowls thin walled can be a lot of fun.

Not only does the wet wood cut smooth, crisp, and storing green wood for turning zero dust free, light easily passes through the thin moisture wood fibers. Place a light source behind zsro bowl once the wall thickness has been reduced and you can use the resulting brightness as your wall thickness gauge.

If the light storing green wood for turning zero through the bowl wall becomes brighter, the wall is getting thinner. Ideally, a continuously even lit appearance down the bowl wall is the goal. Also, when turning very thin-walled green wood bowls, the amount of area to hold tunring has dramatically been reduced. This means the green wood will dry very fast, so you need turniing work rapidly.

Spraying a mist Storing Green Wood For Turning 60 of water from a water bottle sprayer on the wood at zego intervals storing green wood for turning zero prevent the wood from drying prematurely as you work. The green wood medium walled bowl is an excellent test for a tree species. Turning green wood bowls about a half-inch to three-quarters of an inch thick are storing green wood for turning zero pretty stable. Again, even wall thickness is the key storing green wood for turning zero preventing too many surprises and nasty cracks.

Where medium thick walled green bowls are fantastic for one species, they may not work at all for another tree species. Turning green wood bowls twice always reminds me of twice baked potatoes. And the process is very similar in a few ways. The principal behind twice turning green wood is first to create a rough bowl shape that can dry and reach equilibrium before being turned a second time to the final finished shape.

We know that green wood is going to storjng, shift, and reshape as it dries. The first stage of twice turnings accounts for this by removing the mass of the wood and creating even walls to allow even moisture to escape. Then the second stage of the twice turned wood bowl takes advantage of the fact the wood is now much more gurning to make a more dependable shaped final bowl. To size the first rough turning for a twice turned green wood bowl, the rough wall thickness is critical.

The rule of thumb is the wall thickness needs to be about ten percent of the overall bowl diameter.

To be safe, you should store wood blanks, before turning them, for as long as possible in an atmosphere close to the intended final environment of the finished turning. This will ensure the minimum movement or warping in the finished piece and prevent splits. You should allow about 4 weeks for 1" thick timber. Q: Where should I store green turning stock? A: Properly sealed green turning stock can be stored in a variety of locations. The best storage areas will have three things: light to moderate air flow, temperatures of degrees, and a moderate amount of humidity. Air flow is important to control the rate of moisture loss. Storing wood near fans, a/c or heating ducts is not recommended. Seasoning Your Own Wood Turning Blanks From Fallen Tree Limbs.: A recent storm broke 2 large limbs on the big cherry tree in my garden. Rather than cut them up for fire wood I decided to turn them into blanks and leave them to season naturally for future use. Cherry is a hard wood that would be expensive .
