Eccentric Woodturning Necklace Centered Inserts
This video is best viewed right here. However, in case of difficulty, is it also posted on YouTube and FaceBook.
This is part of a series on eccentric turning in preparation for Valentine’s Day.
In this project video, I turn a medallion or pendant and insert different woods for visual interest. The position is fixed for this project so that each wood is concentric but different diameters
The main wood is sycamore with a walnut backing. The inserts are walnut, maple, and padauk.
The main accessory is a shop-made chuck based on “Build A Shopmade Chuck For Offset Turnings” by David Mueller. American Woodturner February 2015. I have adapted this chuck to have exchangeable work platforms that interchange with the Infinite Axis Chuck that I designed.
Turning went much easier with a couple more accessories:
- 2 screw chucks (3/8″) for direct mount of the work platform to the lathe spindle.
- Flat faced faceplate sized for target diameter also used to press double sided tape bonding.
- Live center with #2 Morse taper and 1 1/4 x 8 tpi.
- Spindle adapter 1″x8 tpi female to 1.25″x8tpi male top adapt the live center from 1″ to 1.25″
Enjoy!
Hello Alan.. I have been watching your weekly turnings for a long time and actually turned quite a few of your projects myself. I am wondering if I missed it or not but at sometime did you do a through demo on how you made your big offset eccentric woodturning chuck? And also how you fabricated the 5 +/- degree guide that you use for fitting one segmented ring into another. Thank you very much. Mike A.
Eccentric Chuck: I have not made a build video because it is very well explained in the American Woodturner article.
5 degree. No, I have not since it varies significantly between lathes and shop capability.
1. I took 1″ black pipe and reduced the diameter on a metal lathe to fit my banjo.
2. 1″ black pipe flange the threads onto the pipe
3. MDF platform screwed to the flange
4. Glue & tack thin wood strips to the platform at the angle for the guide.
Alan
Do you have plans for your off center chuck?
The plans are well described in the original article reference in the description. It is available via Amaerican Woodturner or with a link provided in the description.
