I've been ask what to I do with green woods. Green wood are both a treasure and a bane. Turning green wood can be a tricky venture but very rewarding. You will find green wood in one of two forms, freshly cut and wax sealed. Both have a common need, to get rid of the water in their cells.

Fresh cut trees are very easy to handle. The first thing you do is remove the pith. This is done by cutting a small amount from the center of the log, basically cutting the log in half with the grain. Then you want to turn a rough bowl, leaving it over-sized.  Leave it at least 1” thick for bowls up to 6-8 inches and 2-3” for larger bowls. There is not an exact number as every wood species dries differently. Once the bowl is roughed you want to slow down the moisture loss, so coat it with a green wood sealer. Don’t be stingy with the sealer either. Once the sealer has set, place the bowl in a protect area out of direct sun light. I have a shed built just for drying bowls; it is well vented with no force air and works very well for my domestic woods. Do not bring the bowls indoors to a headed environment, the bowl will dry too quickly and they will crack. If you’re in a very dry area of the country the bowl can be placed in a brown paper bag to help slow the drying process even more. It’s important to weight the bowl after waxing and writing the weight on the bowl. By checking the weight every month or so you can tell when it is dry as it will stop losing weight.

Waxed cover woods are a different kind of animal. What you do with it depends on if it is an exotic or domestic wood. If it’s domestic you will follow the directions for green woods above. If it’s exotic the best thing to do is leave it alone for period of time depending on the species. You've spend a bit of money buying exotic wood the last thing you need is a bunch of firewood. Never place and exotic waxed wood in a heated environment, they will surly split. An unheated garage or shed is perfect, but protect from high heat also. I keep all my waxed exotics in an attached garage and buy in the fall, winter and spring. This gives the wood a chance to adjust and build up to the high heat of summer (I live in Texas).

Turning exotic wood takes time and I've had great success with letting them sit for up to a year before attempting to turn. I know that sound crazy but if you spend the money you need to take care of the wood! 

There are ways to speed this up but it depends on what you’re making. If you want to turn small bowls you can cut the block in half, a 2x6x6 become a 1x6x6, and then reseal the cut side. This will in affect cut your drying time in half. Never scrape the wax off thinking this will speed it up, they will crack. They are waxed for a reason.

You can treat the waxed wood just like green wood and turn it thick. I would always place it in a paper bag after rough turning and waxing.

There are some exotic that will never dry out, camphor burl is one. I've had a block for 4 years and was still wet on the inside, it was 2” thick. So then you start the green wood process.

Once you get to know your woods you’ll find the best way to work them. There is no grantee when it comes to wax cover wood so don’t cry over split blocks learn from it and try again. Just take it slow and the reward will come when you've complete the journey!
