Thermed Chair

Thermed Chair

This three-legged chair/stool/end table is 18 inches tall. The legs were formed from glued-up layers of Bubinga, Alder, Mahogany, Maple and Cherry. All legs were turned on a lathe using a technique known as therming which produces unique shapes with curved surfaces. Also known as drum turning, a therming rig (shown on the bottom of the thumbnail image) mounts several spindles off-center so that all shapes are turned simultaneously. Once a surface is turned, each spindle is rotated the desired amount and the next surface is turned. Therming enables a broad range of design approaches not available with on-center turning. The technique has been used by furniture makers since the 1700s to make unique table legs and spindles. The Maple top seat, portions of the legs and the Bubinga brace platform were enhanced with surface embellishments. Finish is Watco oil buffed on the Beall system.
With all the nice work you've shown I wonder if you can give us a picture of your therming
jig and set-up.

Do you do the turning after the therming ?

You have such a variety of work I'm impressed with your ability.
Frank, thanks for the comments. Therming is a technique that utilizes an off center rig (or drum) to turn multiple spindles simultaneously. OK, this may not make sense with just words, so I have prepared a tutorial on 'Creating a 3-legged Thermed Stool'. Go to the Forums under the 'Tutorials and Tips' tab and you will see this tutorial listed. There you can download a PDF presentation that describes the process and how to make the therming set-up. Let me know if you have any questions and thanks again for your comments!

P.S. if you look closely at the thumbnail of my image you will see the therming rig with all three legs mounted
