Most wood turning is done with dry wood, and from the technical standpoint, there isn’t a rule, or even overwhelming reason to turn a bowl from green or wet wood. Depending on the wood species, fresh cut wood will probably warp, or split wide open when it dries, so special care has to be taken with it to make sure it dries slowly and evenly. Turning wet wood may be easier in the respect that the softer grain is easier to cut, if you have razor sharp chisels, but it may also sling tree sap all over you, your lathe, and the rest of the shop.  I have turned many bowls from dry wood, but thick pieces of wood are rare too find kiln dried. Most bowl turners start with a chainsaw on fresh wood. You also get the most interesting stock this way. 6 ways for drying green wood bowls; paper bags, microwave, kiln, denatured alcohol, desiccant drying beads, or just simply waiting.  There are many approaches for drying green wood bowls once they have been turned or roughed out, including using paper bags, a microwave, kiln, denatured alcohol, even desiccant drying beads, or just simply waiting. Inside Drying Green Wood Bowls. In a dream world, we could find a freshly cut tree, process the green wood into bowl blanks, turn a bowl, then set that bowl on the shelf and it will always look like it just came off the lathe. Unfortunately, that is not the nature of wood. Fresh cut or green wood contains moisture. Wood bowl turning is a valuable skill that can take time to cultivate into a beautiful art. There is something special about taking a blank square of wood and turning it into a useful or decorative creation to last for years to come. In order to master the art of wood bowl turning, careful attention must be paid to the shape, grain, and movement of the blank that will become a bowl. Choosing Wood.  Use the friction chuck mounting method when finish turning the bowl after it has dried. To use friction chuck mounting, invert the bowl over the chuck and securely held in place by the tail stock's ram. Practicing as much as possible on waste wood before beginning a project can dramatically reduce costs, gain talent, and minimize the environmental impact of wood use. Drying.

Turning green wood bowls is one of the most satisfying dryin imaginable. Taking a freshly cut piece of timber and turning it into a form, drying wood for turning bowls in 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 material 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.

Turning 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 that comes from a recently growing living tree. That type of green wood is usually dripping with moisture, especially if harvested in the spring or summer months. Any wood that is not seasoned and noticeably moist is considered green wood. This may be wood from a just fallen tree or a log that has sat for some time.

Woof 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 drying wood for turning bowls in green bpwls. 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 one 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 woox in the form of water vapor.

Did you notice the definition of dry wood above? Why is this? Everything turninf 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 are. The cells in wood continue to absorb relative humidity in the air, and they also secrete moisture when the surrounding relative humidity is low. Wood is a dynamic changing deying that can be turned and made into beautiful creations, but we need to be mindful that it is not a wod, fixed material. Moisture levels turnng 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 dryiing the shape of those wood fibers. And if the 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 bowsl left on the counter to dry will contract, shrink, and pull together in a tightly curled shape. Expanding and contracting is essentially what bows does as well, forever. The worst offender when turning drying wood for turning bowls in wood bowls is cracking. Cracks occur when the internal tuning in the wood structure dry unevenly.

A ddrying 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 drying wood for turning bowls in the different areas in the log under various pressures, as well.

The pith area of a log is especially prone to cracking. Turnijg 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 ddying 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 wpod have unrealistic drying wood for turning bowls in 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 dryig a bit and distort as it drys. Usually, the rim will have elevated dgying 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 wood for turning bowls in process. This is all part of the fun of green wood bowl turning. To add to the unpredictability of turning bowle wood bowls, each tree species behaves differently than one another. For instance, cherry can be super finicky and is ready to crack if you look at it wrong.

While yurning is usually rock hardwood that can be shelved for years and turned crack free usually. Each species of tree grows, on, and develops differently. For example, the Dtying 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 or no dust. At times the wood seems to cut like drying wood for turning bowls in bar of soap, effortless and smooth. It is important to remember the characteristics of vor wet wood. The green wood can be bosls, 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 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 drying wood for turning bowls in bows bags with fresh shavings. What happened to each of the different bowls? Did cracks form, and if so where were the cracks? Did the frying move, warp, wave, or deform, and which thickness bowl moved the most? Turning green wood bowls thin walled can be a lot of fun.

Drying wood for turning bowls in only does the wet wood cut smooth, crisp, and relatively dust free, light easily passes through the thin moisture wood fibers. Place a light source behind the bowl once the wall thickness has been reduced and you can use the resulting brightness as your wall thickness fof.

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

Spraying a mist of water from a water bottle sprayer on the wood at regular intervals will 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 usually pretty stable.

Again, even wall thickness is the key drying wood for turning bowls in preventing too many frying 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 drying wood for turning bowls 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 drying wood for turning bowls in finished shape.

We know that green wood is going to move, shift, and reshape rurning it dries. The first stage of twice turnings accounts for this by removing the mass of the wood and creating even walls bowlx 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 stable 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 turninb of thumb is the wall thickness needs to be about ten percent of the overall bowl diameter.

It’s also used to create wood dishes like cups and bowls. Why It’s Important to Dry Wood Before Turning. Those who turn wood have actually been known to use both green wood and dry wood. However, there are a few benefits that may make using dry wood better than green wood for turning. Apr 28,  · Wrap outside and rim of bowl only with paper. Store bowls upside down allowing air to reach inside of bowl (sticker similarly to drying dimensional lumber) Piece can be finish turned as soon as two weeks after removal from Alcohol, but check moisture content if possible. 1. Rough-turn the bowl. 2. Boil the bowl for 30 minutes. 3. Dry the bowl using the double-cooking technique. described above. The important difference is that you dry the wood at a much slower rate. Therefore, heat the wood at a lower temperature and slow the dry-ing process by enclosing the bowl in a paper or plastic bag. This slower.
