If you do research on the web, drying wood for turning bowls videos been to the AAW symposiums, go to any of the other symposiums, or even talk with other turners, you will hear drying wood for turning bowls videos kinds of different techniques for drying wood. Most of us start by turning wet wood to finished products.

This is much easier to learn to turn, and much shorter time to obtain feedback. The downside is these vessels tend to move as they dry.

Some woods have bwls movement, and can produce rather ugly turnings. Properly planned, you can produce vessels that move and create beautiful pieces. I personally prefer functional pieces to be what I turn, drying wood for turning bowls videos how the wood wants to move.

So I need to be able to dry wood for these pieces. I will try to describe my understanding and experiences with these processes in this white paper. Drying wood for turning bowls videos have NOT done controlled experiments or collected data across a wide variety of wood types. Please do NOT take this as gospel, but just documentation blwls my current thoughts and the processes that I use.

If you want more info, a quick search on the web will point you to the latest info on any of these methods. In the end, use the technique that you are the drying wood for turning bowls videos comfortable with. Start by rough turning your vessel. I have had problems with cracks regardless of what process I use when the vessel is too thick. Occasionally I do have problems where the vessel is cannot be turned again, due to the wood moving enough that the wall thickness is not enough.

Now it is time to dry the turnings so that they will be stabilized and ready for final turning. I use 3 different processes, boiling, bagging, and sealing. Why not just 1? If you could see me right now, you would see me shrug my shoulders. Boiling longer will not harm things. You must be careful to not have the turning jam in the pot and act like a steam pot lid. If it does, it could explode.

This would not be good. Boels NOT do the boiling in the kitchen with a pot that you would like to continue using for something other than boiling wood. The pot will not be videks for anything other than boiling wood. John Brugo use to boil our turnings in an old water heater tank outside. So you need a good heat source and a large pot. Turkey boilers, crab pot cookers, etc make great sources for heat.

The vessels need to be completely under water, or at least such that they would be covered if the vessels touched the bottom. If you boil for an extended period of time, gideos may need to add water. You would not want to have any more water than required to minimize costs.

Once done boiling, allow the vessels to cool in the wod overnight. Do not remove from the water till the water has reached drying wood for turning bowls videos air temperature. If you remove them too quickly, the pieces will crack. Sad to waste this viddeos time to have this happen. Set the vessels out and allow them to dry. There will be some surface dis-colorization, but it does not go very deep, and turns off when you do the final turning. In summary, the cons are that this is relatively expensive to get set up and videox fair amount of work for one or two vessels.

This process is something that takes constant supervision. After rough turning, I will place the vessel in a brown paper bag. If the humidity is low, I will use two or three bags for the first couple of weeks, and then reduce to 2 bags for a week, and then finally 1 bag. If the wood is very wet, you will need to change the bags every day till the bags are not wet the next day. I keep these bagged vessels on the floor of the shop, with no air flow.

After a couple of tugning, I will move the vessels onto a rack to allow them to finish drying. These vessels can take 6 months to 2 years to dry, depending upon the type of wood. Walnut usually dries in 3 to 4 months. Maple has been closer to 6 months. Do not use plastic bags. This does limit the drying, but it does create an environment that is likely to cause the wood to rot.

Rather than just leaving them out of bag completely, this is a way to continue to control drying wood for turning bowls videos drying not accelerating, but slowing. The cons of this process are that it takes lots of attention, and does not dry things quickly. If you accelerate the drying time, you will increase the probability of cracks. The pros are turnong it is cheap.

A great recycle nowls bags from the grocery store. After rough turning, I put a single coat of anchor seal on the outside of the vessel. Then set the vessel aside in an area with little or no air flow. After a month or two, I will stack them on a rack where they can continue to dry. If the wood is a variety that tends to have significant movement, I will put two coats on the outside, and one on the inside. This slows the drying significantly. This process can be combined with bagging when I feel like it.

The cons of this are that it can cause it to take forever to dry. I have some Walnut that is 18 months drying wood for turning bowls videos now, and still wet. The pros are that I really only have to deal with it a couple of times, so it takes the least amount of my attention. Jim also likes it because I use more Anchor Seal. But good meters can be expensive, and to get accurate readings you need to poke holes in the wood. In addition, dry is a relative thing.

Dry in Phoenix and dry in Hawaii are radically different. It all has to do with the moisture content of the air. If the moisture level varies radically over the year, the wood will swell and shrink over the year. So exact moisture readings are not exactly what you are looking for.

Might make us geeks feel good, but not particularly meaningful. I use a very simple method, an electronic fish scale with a net basket. I weigh the wood, and when it stops losing weight, it has reached equilibrium with the air. After rough turning a piece, I weigh the piece and mark it. My marking includes the date weighed and the weight. It is that simple. All we are trying to measure is that it has stopped losing weight, not how much it weighs. The list of methods to dry wood is endless, and it seems that I hear about a new method every couple of drying wood for turning bowls videos. Some I really have to what in the world qood you try that?

In any case, here is a list of a drying wood for turning bowls videos more methods that you might hear about or want to try:. This is something that is being done commercially in Europe, and some here drying wood for turning bowls videos the US.

It involves using a combination of heat and fpr to dry wood. We have some local people that are using this to finish drying dry wood. The basics of this are fairly simple, as the pressure is reduced, the boiling temperature of water comes down. By lowering the pressure enough, you can make water boil at room temperature.

The water turns into vapor and is removed from the wood. I had drying wood for turning bowls videos bright idea of trying to build a vacuum kiln, as the commercial sites claim to be able to dry wood in a few days rather than months.

This winter I will run the experiment again and see if it will work. This is the commercial method for drying wood. A number of turners have created kilns which are relatively cheap to operate and ivdeos.

Some wood create strong odors. The process is rather simple. Wrap you piece in paper towels. Place in the microwave and use the defrost cycle. You need the piece to get hot, but not too hot. Start with short times and work your way up. If you get it too hot, it can catch on fire. I went one cycle too far.

Jul 13,  · How long exactly a given bowl will take to dry is dependent on a number of factors: how wet the blank is, how thick the wall and the species of wood all factor into the equation. A beech bowl will take longer than a cherry bowl, and a rough-turned blank will take longer than a finished turned one. Vacuum drying Kiln drying Microwave drying Freeze drying Alcohol drying (DNA) Soap Drying (LDD) PEG. Vacuum Drying. This is something that is being done commercially in Europe, and some here in the US. It involves using a combination of heat and vacuum to dry wood.
