This month our club's challenge was to turn a kuksa. What's a kuksa? It is a drinking vessel from northern Scandinavia often carved from birch burl. However, I prefer woodturning over carving.
My kuksa is from walnut. Since my wood is less than three inches, I glued some pine to its top and bottom to give me room for tenons.
The process I followed was:
1. Glue waste wood (pine) to augment its thickness.
2. Mount between centers to rough turn and cut a tenon on the end opposite the sphere.
3. Remount with the tenon and turn the sphere using the octagon method to guide my eye.
4. Press the sphere end against the chuck jaws with the live center.
5. Cut a tenon on the sphere.
6. Remount using this new tenon and hollow the sphere into a cup.
7. Turn off the foot. There are alternative for this. I used my wooden chuck jaws.
8. Shape and sand the handle
9. Since this could be used as a drinking vessel, apply a food safe finish such as mineral oil and beeswax mix.
One day, I sat down and worked out the geometry and did the math for an octagon when given a certain diameter.
Length of a side of octagon =Diameter/(1+(2/SQRT(2)))
Length from end to 1st corner: = Side *SQRT(2)/2
From there, Excel does the heavy lifting
My kuksa is 3 inches by 6 inches and is 2 inches tall.
Enjoy!

Fascinating turning project. You make it look so easy.
Really like that, have lots of walnut
Hi Alan! Great project my friend! Lovely piece! Cheers! Daniel
Beautiful job my friend 👍🏼
Really interesting cup. I liked the jaws that you made for you chuck. Nice video, thanks for sharing.
Nice project Alan!
Alan, you sure come up with some interesting wood projects. I like the belt sander for the large to. Best regards, Richard
Interesting project - added to my list!
hermoso como siempre gracias por ello jorge de argentina
Great project Alan, very timely too, I have been asked to make a period Viking drinking vessel. I have just made my version of the Kuska today, I t is not as pretty as yours, but mine does look like a period piece, a little rough around the edges. A fun lathe project, much more fun than hand carving it.
Interesting cup.
Looks good. One thing I like to do is to cut the waste off the handle before hollowing. It reduces the vibration during the hollowing and I can turn at a faster speed. But my lathed isn't as heavy as yours too.
Excellent ...
Lovely
As someone who wore gloves professionally for his career get a box of nitrile gloves. They fit much better and give almost the same tactile sense as a bare hand. Love your videos
neat project Alan, you gotta keep you fingers out of the way of sharp things! I never realize how much u value a finger until one is injured. take care.
Muy orijinal todo lo que haces enorabuena
Hi Alan Great video hope you hand is soon back in action take care Y.N.W.A. Paul
