So the next question is what do you want to turn?  I have been turning green wood for 20+ years and vary rarely have the bowls cracked. I first turn the blank so the walls are between 7/8 to 1 inch thick. I then microwave the rough turned blank (obviously has to fit in microwave) for between and 4 minutes (depending on the size of the blank). The larger the blank the more time you can "cook it". When it comes out of the oven, you should be able to hold it in your hands without your having to let it go. If you can' hold it, you cooked it too long.

Turning bowls from green wood is a centuries-old practice. Ror a bowl will warp oval as it dries. After letting the blank dry for about three months, they re-turn it round and to a pleasing wall thickness. Why not just let the blank dry and 777 a bowl from it once dry? Every material has an amount it can bend before breaking. Important to this discussion is that wood only shrinks about 0.

However, it shrinks 4. The same log also shrinks 7. Turnkng specific numbers are an average of all species worldwide, but the point is that the average log loses circumference at about twice the rate it loses diameter. This means that circular stress is going to dryint around each annular ring. Also, as your roughed-out bowl is sitting on a shelf drying for three months, the end grain will lose water faster than the face grain areas.

This causes faster shrinkage in the end grain, making checking likely. Wrapping a freshly turned green bowl in sheets of newspaper or putting it in a paper grocery bag can create a sufficient vapor barrier to allow face grain wod dry at about the same rate as the end grain. Some turners also paint the freshly turned blank with dtying wood sealers used by the forestry industry.

This will cause uniform drying, but it adds a month or two to the drying time. Speaking of time, many turners want to reduce that three-month drying period. Take note, though: while practicing the science related to wood drying will greatly increase the probability of good results, in real world practice, you will sometimes get a failure even from theclearest of woods coated with wax. At other times, drying wood for turning bowls 77 funky piece of wood thrown in the corner with no paper or wax will dry just fine.

Chemically, detergents are surfactants, substances that reduce the surface tension of a liquid. You can boowls wonderful results from soaking your bowl overnight, but three days drying wood for turning bowls 77 the optimum time. After soaking, you have two options. The first option is to finish turn the bowl to a thinner wall immediately.

The surfactant makes the final turning go much easier, with much less tearout in the end grain by the tools. There is also an improvement in sanding, with less clogging of the sandpaper. The detergent woov to further reduce checking in clear vowls. The second option is to allow the rough-turned blank to air dry before re-turning. Drying time is reduced and checking becomes nonexistent — even without wrapping in paper or waxing. It seems the surfactant is accelerating the water transfer across the cell membranes.

Despite Internet claims of a reduction in warping during dryinh, there is no change in the ultimate warping of the wood. There is, however, some debate on the process changing the color of the wood. I have personally found drying wood for turning bowls 77 change in color or how the wood accepts a final oil finish, but I have drying wood for turning bowls 77 reports of various lacquer finishes reacting badly to the detergent. This method involves placing your rough-turned bowl in a plastic bag and microwaving it on a defrost cycle until you start to cor steam.

The blank is removed from the bag and allowed to cool to room temperature. The process is repeated again and again, until you no longer see steam and there is the predictable warping, or until the weight of your wood has dropped by one-third. Even with the most careful finding of the right woodd setting on your microwave, drying wood for turning bowls 77 complete cooling out of the bag and reversing the bag to dry the moisture out of it, you may get some checking.

Overall, I consider it an emergency triage method only! This method involves placing your rough- or finish-turned bowl into a plastic bag filled with desiccant pellets. Desiccant pellets are used widely in industry to dry items quickly and to keep them dry during shipment. The pellets come in a plastic bag sealed in a screw-top pail with a rubber gasket which keeps them dry until you want to use them. The pellets have a chemical indicator that makes them turn reddish as they absorb water and become expended.

They can, however, be used over and over: once they have turned red, they may be heated in an oven, which brings them back to new condition. A convection oven works best, with the drying wood for turning bowls 77 spread in a thin bbowls on cookie sheets. They are in new condition in two to two-and-a-half hours.

They will still work, but knowing when they are expended will be problematic. The bowl must be completely buried, with its inside full and at least one inch of pellets in all directions.

Incomplete burial will result in checking. 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. How do you know when your bowl is dry enough? The best way is to first place your freshly turjing bowl on a kitchen scale and weigh it. After 24 hours, weigh it again. When it has lost at least one-third of its weight, you can apply finish to a once-turned bowl or re-turn a roughed-out bowl.

Overall, for thin final walls, leaving the bowl in for about 24 hours will dryng do the job. Drying wood for turning bowls 77 a rough-turned blank, drying will usually take about 48 hours. You can also immerse a finish-turned bowl in the desiccant for a vowls of hours, then remount it in the lathe for finish sanding. This saves time and sandpaper, because the surface is drying wood for turning bowls 77 foe to bowlz well erying clogging the sandpaper.

Then place the bowl fpr in the desiccant for final drying before you apply finish. The tunring process effortlessly speeds things up immensely. You can order a kit of the desiccant from rockler.
