first segmented turning
Well, I had to try sooner or later. Encouraged by efforts reported here, and
by turnings I recently saw locally, I had to give it a try. I am aware of some mistakes and will likely discover others when I try again later. Back in about 1950-56 my dad had a little store in Minneapolis, selling what he called custom woods. He had samples from countries which now no longer exist, and other countries we can no longer visit. He had samples of woods which may not even be readily available any more. Some of these pieces were labeled, and other not - or the labels no longer readable. It seemed natural, finally, to try to glue some of them together and see what woujld happen. This is a smallish jar with lid. Glued up with yellow glue and extra waste blocks on each end to maximize the amount of usable hardwood for the project. I turned the basic shape between centers, parting off a section for the lid. Head end was on a faceplate, so now I could bore out the interior with a forstner bit. Once the inside was opened up, I finished with a home made hook. The inside was trued up with a home made curved scraper tool also seen on the flickr site. Sanding through to 400 grit and burnished with wood shavings, the final finish is paste wax. There are some fine scratches I did not see until after the waxing. I did mount the lid and the jar to a chuck for the final work and sanding stages. My chuck is a Penn Industries bowl chuck, and I have mounted some 1 1/2 inch thick softwood scraps to the face of the chuck with bolts. Open the chuck about halfway and then turn as if I were making a basic friction chuck - except that I did not have to be so fussy on the inside diameter and could tighten and loosen the chuck as needed - also had enough grip range for the diffeent diameters on the lid, then turned the setup again, to the larger diameter needed for the jar itself, for turning the foot. I noticed that it was really jarring (no pun intended) to turn something with these varying degrees of hardness, plus the sudden changess from end grain to face grain. The hard maple had some difficult aspects, as it was a chunk of curly maple left over from a flintlock project of years ago. Had some interesting chatter on the top of the lid. Bearings are decent on the lathe, so am hoping it was just finding the best speed for the turning and the best angle of attack for the tools... and not quite succeeding yet. The ebony finial was turned separately with a spigot on the end, set into a turned bore in the top of the lid, and glued. www.flickr.com/photos/55616gandy/ Comments, questions and critiques, it's all good for me. tom koehler -- I will find a way or make one. |

Nice Tom. I particularly like the effect of the opposing grain ribbon
through the middle. At first though, I thought the turning a little thick-ish, but the more I looked at it, the more I liked it. -- Jack GO GREEN - RECYCLE CONGRESS http://jbstein.com On 10/9/2010 4:59 PM, tom koehler wrote: Well, I had to try sooner or later.

(in message ): Nice Tom. I particularly like the effect of the opposing grain ribbon through the middle. At first though, I thought the turning a little thick-ish, but the more I looked at it, the more I liked it. Thank you for looking at my work andd commenting. I do appreciate it very much. This particular shape is my favorite, I think. For my want of knowing what may be a more widely known or accepted name for this form, I call it a tulip shape. I have (or had) only a very limited amount of the black mangrove, and wanted to maximize its visual mass in the turning. It is kind of thick-waisted for this reason. Also, I knew it was going to be a smallish vessel and so wanted to maximize its interior volume, being able to have significant hollow space clear down to the foot. Below the upper lip, the walls are about 5/16" thick. I wanted to make the walls thinner, but not knowing how well the wood and the glue lines would hold up under the stresses of turning, I decided to let well enough alone. For background, I do have an older turning, a small bowl I made maybe 25 years ago from red elm and maple in two layers or laminations, that separated at the glue line. The turning is somewhat thin by my standards, and for some reason it separated for about 1/3 of the circumference. It was not completely a failure of the glue itself, as there are some places along this line that the failure was in the red elm. I know that wood never really stops moving, even when apparently well dried - until it is reduced to ashes. I admire the skill of a turner who can consistently produce thin-walled vessels of uniform thickness (thin-ness?) My own skills and experience dictate somewhat thicker walls. tom koehler -- I will find a way or make one. |

Segmented turning is a great way to use up those scraps and you can get such varying results. I think the unknown wood may be teak. Hard to tell from the photo,but it looks an awful lot like it to me. Does it have sort of a soapy feel? The teak I've turned had a very distinct feel to it when worked. It tools nicely. Hope to see more coming out of your shop Tom... ....Kevin -- Kevin Miller - http://www.alaska.net/~atftb Juneau, Alaska In a recent survey, 7 out of 10 hard drives preferred Linux Registered Linux User No: 307357, http://counter.li.org |

Thanks for the hint. Thanks also for the encouragement. tom -- I will find a way or make one. |
