Buckeye burl - undyed, unstabilized
Not all buckeye burl comes dyed and stabilized. A while ago I purchased a block of it and, while the outside was coated with the typical wax, it had been neither dyed, nor stabilized. It is very soft in this state, almost like a rotten log. It weighs nothing, being on a par with balsa wood. It has no structural strength whatsoever either. If it weren't so beautiful, it would be worthless. I've done some reading and it appears that the characteristic blue color is caused by a sapstain fungus. Exposure to air makes it more pronounced. I sincerely doubt I could get any of this through Australian customs unless it were stabilized, it is so soft and rotten.
I have taken a series of photographs of this block along with some freshly cut turning sticks. They were cut at approx. 22mm x 22mm x 200mm. Tubes for an Emperor pen are included for scale. More photos of it on the mandrel.
The last three photographs are the most interesting, in my opinion. I tried to keep the piece on the left in the same position for each photo. The third to last shot shows the pen blank turned to the bushings and sanded to P320. The second to last shot shows it one minute later after BLO was applied. I have mentioned before what BLO will do to this timber. It radically changed the color, yet kept the character. In the last photo, twenty coats of CA have been applied, stopping after ten coats and micromeshing to 12,000 before applying the last ten coats. This timber is so soft and light that it drinks in the first half dozen coats before any CA buildup can even start to begin.
Tomorrow, a final polishing and it will become an Emperor pen.When all is said and done, there is usually a whole lot more said than done.

Thanks for thant info Al, did not realize it was such a light weight porous timber. No wonder the BLO changes the colour. Amos

Thank you Al, that's terrific information.
Great picture and of course not to forget another outstanding pen, what a bottler. Attachment 86805
You have me itching to turn another one. Like you say I doubt it would make it through customs unless it was stabilized.

Thats amazing. Its going to make a really nice pen.
Were you scared of turning it because it was so soft?
Also out of curiosity, what tree does it come off?

You just have to use sharp tools and take light cuts. Too much pressure and your gouge will dig right in, the timber is so soft. Even with the sharpest tools, you can see the surface tearing rather than a clean cut. The sanding step smooths that out.
The tree is Aeculus octandra. Family Hippocastanaceae. It is an American tree. It ranges from the Appalachians of Pennsylvania, Virginia, and North Carolina westward to Oklahoma, Kansas, and Texas. 30 to 70 feet high and two feet in diameter, it grows best in rich, moist soil along the banks of streams and rivers. It is one of the initial trees to leaf out in the spring, the twigs have a foul odor when broken, and the nuts and twigs are poisonous, containing a cytotoxin.
The burls primarily come from the root balls. After a tree is cut down, they dig up the burl. It is often quite large, filling the scoop of a front end loader. The roots come out of it.When all is said and done, there is usually a whole lot more said than done.

finishing question
Many thanks for the tips cisco, just working on my first piece today (managed to get a few pieces through customs ).
The BLO made a pretty dramatic difference to the colour . looks stunning in the flesh!
small question though - how long did you wait for the BLO to dry before you did the finish?
From your original post I got the impression you went on with the CA immediately, is this right or did you wait a few hours/days?
cheers

Well, I just dampen an old rag with the BLO and burnish it on the blank while the lathe is spinning. I'm not soaking it or anything. Then I take a clean portion of the same cloth and run it on it to remove any extra that might be there. Then I reach for the CA. First coat of CA goes on about 60 seconds or so after the oil. Haven't had any problems yet.
That is a dramatic change when the BLO hits it, isn't it? Looking forward to seeing your results.When all is said and done, there is usually a whole lot more said than done.

Excuse my ignorance, but is Buckeye Burl the same as Box Elder Burl?

No. I think box elder is a form of maple. Box Elder, or Boxelder Maple, (Acer negundo) is a species of maple native to North America. In Canada it is called Manitoba maple and in Russia it is called American maple. It is the only North American maple with compound leaves. It is a small, fast-growing tree that grows up to 25m tall. It often has several trunks and can form impenetrable thickets. When I bought my farm ten years ago, I had about seven or eight acres of the stuff down by the river. Cost me $1,000 to have a guy with a bull dozer clean it all out for me. Took him two days.
It is invasive and can quickly colonize both cultivated and uncultivated areas and has become naturalized in eastern China. It can also be found in some of the cooler areas of the Australian continent where it is listed as a pest invasive species. At least, that's what Wikipedia says, and we all know about that.

Buckeye trees are much larger, more noble affairs. Native primarily to the Midwestern and lower Great Plains of the U.S. extending southeast into the Nashville Basin. Also can be found in the extreme southwest of Ontario, on Walpole Island, and in Lake St. Clair and isolated populations in the South. The leaves are palmately compound with five leaflets. The fruit is a round, spiny capsule 5 cm in diameter containing one to three nut-like seeds, 2-3 cm in diameter, brown with a whitish basil scar. This nut is what I fondly remember playing with as a child. Ohio is known as the Buckeye state and I was born there. The hard nuts, when thrown properly, will raise welts on older sisters (I could run really fast as a child). The buckeye confection, made to resemble the tree's nut, is made by dipping a spoonful of peanut butter fudge in milk chocolate, leaving a circle of the peanut butter exposed. These are a popular treat in Ohio during the Christmas and NCAA college football seasons.
While in North America it is referred to as the buckeye, Eurasian species are referred to as a horse-chestnut. In Britain, they are sometimes called conker trees because of their link with the game of conkers, played with the nuts, also called conkers. It is not a true chestnut. The use of the term horse-chestnut refers to their strength or inedibility. The name buckeye derives from the resemblance of the seed to the brown eye of a male deer.When all is said and done, there is usually a whole lot more said than done.
