Learn woodturning with Philip Greenwood – demonstrator at clubs and shows and author for the woodturning magazine. Although these tools do permit more complex operations to be performed on the lathe, the basic process is unchanged, and many of the finest woodturning artists achieve beautiful results without the most expensive new devices. Your friends at Carter and Son are looking forward to another exciting year making wood chips with you. That is, the wood is free to move and to relieve stress rather than relieving the stress by cracking. You can sand while green, but it takes a lot more time than when the wood is already dry. These tools are generally formed from high-speed steel and are roughly U-shaped in cross-section.
There are many wood turners who prefer to rough turn a blank leaving it thick, about a 1 wall, and drying the roughed out bowl for three to six months, then remounting the bowl and finish turning it. This is risky because it does not remove enough mass, and checking and cracking may occur. Because the sealer leaves a waxy surface, mark blanks that will be completely coated before applying the sealer. Using the alcohol soak method reduces the drying time for roughed out bowls from months to weeks.
There are exceptions to this rule – I have found a supply of imported American cherry, ash, maple etc which is correctly kiln dried down to 12% moisture or so. If you do find really well seasoned wood you will have to pay a high price for it. The extreme unsymmetrical nature of the burl is very clear in these images, and you can understand the difficulty deciding how to mount it on the lathe. This can slow the alcohol drying process down to 1 or two months but it is worth it to prevent those darn cracks.
Turning green wood is kind of a messy affair as depending on the wood and its density can leave you soaked in sap that gets flung out by centrifugal force when the piece is spun on the lathe. The traditional rule-of-thumb for air-drying lumber is to allow one year of drying time per inch of wood thickness; this adage obviously only takes a few of the aforementioned variables into account, but it’s at least a rough starting point in understanding the time investment required in order to properly air-dry lumber. I didn’t know that a goblet—an item of such small, intricate detail—could be made from wood on a lathe as large as the ones we used.
Work of this nature, where the diameter of the workpiece is large in relation to its thickness and where the piece is normally mounted from only one side, is known as ‘faceplate’ turning – even if you use a chuck instead of a faceplate. Who For: open to be booked by individuals; these courses can have up to four people attending; ages 18+; novices and experienced woodworkers alike. Woodturners are typically working with small blanks that have a small side grain to end grain ratio.
Getting your hands on it is not as easy as it used to be, as more people are looking to reduce their heating costs and wood burning is becoming popular, even being considered as environmentally desirable. Irregularities in how a tree grows mean there will be dips and protrusions of the dark core wood but overall, I was able to reduce the amount of white wood considerably.
There are several products you can use to help seal the ends of the turning blanks, as well as all surface areas. These create an ideal environment to dry green wood bowls and related roughed out green wood projects. So may plan was to seal the blanks (to help with evenness) and then add airflow and heat to control (accelerate) the speed. I eagerly tested the Tyvek material and found out that it works superbly as a bag material for drying green wood roughouts. If cracks have occurred, then I sand some of the olive wood with 220 grit sandpaper, take the dust and mix it with slow setting epoxy, and use it to fill the cracks.
