Modeling "Leaf Extraodinaire"

In this months issue of American Woodturner Tim Yodler teaches us how to turn a "German Ring turning".

I couldn't leaf this idea alone, I just had to try and model it. I haven't tried turning it yet but I think that turning is way harder than modeling it.

This model made my PC groan! Below are some hints on the process.

The finished model
Turn it on the Virtual Lathe
  • Imported a leaf graphic to use as a model.
  • Draw with line tools over it on the grid insuring it was "closed".
  • Then "turn it" on the virtual lathe

Getting the 1/8 section
  • Group and copy the entire turning to the right of the lathe
  • Insert 4 panels into the truning to create the angled surfaces
  • Select it all and ungroup every thing
  • With it all selected "intersect" it
  • Delete all the surfaces except for one 1/8 section 
Getting the 1/8 section

That was fun! Now I need to turn one, not so easy?

Holy Water Font

I just completed the Holy Water Font. Above you can see the model and the finished project.

This project included many disciplines, woodturning, inlays, guilding and metal spinning.
In this post I will focus on the modelling part of the project. Turning details can be found at

View Extents
Above you can see all the objects of the model. The main part of the models object can be seen on the virtual lathe. These parts were assembled and colored to the right.

Turning at the Virtual Lathe

Seen in this close up all the components were modeled in the round. Then the halfmoons (lower right and left of the back) were subtracted from the back by intersecting 3D circles with the model. Note: I decided not to use these in the real model. Also the ring that held the AL dish was designed with a solid bottom but I made it an open ring during turning since I was afraid it would retain water.

The Rings
The rings were also modeled in 3D. I decided to use the flat model on the right for the actual carving but used the 3d version on the left for the model printouts.

The AL Dish
This story stick printed full scale was used to make the spinning mandrel.

The Final Assembly

Above you can see the final assembly, where the fit was tested.

Go buy the book "Woodturning with SketchUp"

Here is a challenge for you!

I did this staved vessel model using SketchUp.

Let me know if you figure out how to do it or one beter. I'll post your accomplishment.
