Woodturning One Scoop After Another
May also be viewed on YouTube.
Recently, I saw Sören Berger turn a scoop. He made it look easy and indeed it is — after you’ve completed one.
This cedar scoop combines elements of spindle turning, multi-axis turning, and bowl turning.
It also includes turning a perfect sphere. A perfect sphere is no problem for me, I have that process down. The difference is that this sphere must be on the end of a handle. I cannot rotate the ball’s axis as I can for an independent sphere.
Soren marked out first for a octagon, then rounded it over for a ball. However, he used his single purpose caliper to make critical measures for the octagon.
I don’t have his caliper – nor do I want a single purpose tool. However, the geometry is simple. I created a spreadsheet to related diameter to critical measures for the octagon. BTW, the length of a side of a polygon is 0.414 times the diameter.
My spreadsheet can be downloaded here.
My scoop is Titan cedar about six inches long with a 2.5 inch diameter bowl, finished with mineral oil and beeswax.
Good turning.
Hi Alan
I like your approach to turning and I really like this scoop.
Got to try one.
Thanks, keep it coming.

Absolutely try one. Fear is your worst enemy.

I never could find the spreadsheet for the segments used to make the round spheres.
Couldn’t see the green highlight but I finally found the link, thanks Alan.
You’re welcome.
Enjoy

Enjoyed the video. The day before watching, I did my first sphere attempt for ball-in-ball using the tangent method. I’m unable to find the spreadsheet that you mentioned.
Thanks

The link to the spreadsheet is in the post 3rd paragraph from the bottom where it says:
“My spreadsheet can be downloaded here.”
It’s in a PDF format compatible with most computers.
