How to Wood Turn the Earth

I have been working on this woodturned globe since early last April. It is now October. The idea behind this woodturned globe was to cut out the patterns of land and ocean as a flat map into a series of 80 triangles. Then those triangles will connect and fold into a sphere. There are two problems to be solved in doing this. The first problem is figuring out how to draw the bits of land and ocean onto each triangle. I used Blender to unwrap the sphere made of triangles. This allowed me to map the world onto those triangles. The second issue is that there is an angle between each triangle that forces all of the triangles into a sphere. The first thing I did was cut out all of the triangles with the land inlaid into the ocean using the CNC. Then, I cut the angles into the sides of the triangles with some jigs that I made for the table saw. When I went to glue everything up it started out okay, but as the pieces got bigger and bigger, the discrepancies between the triangles also got bigger and bigger. Something was terribly wrong. I put the project down for about 5 months while I thought about how this was supposed to work. I decided the error I had made was looking at the surface of the sphere and taking the angle between the triangles and just dividing this in half to get the angle of the sides of the triangles. This is not quite correct. I modeled a sphere using the actual thickness of the triangles and actually measured what the sides of the triangles would be in that sphere. This gave a subtle difference in the angles. I cut out an entire second batch of triangles and remade a new sphere and this time it worked. Once I had the sphere built, I could wood turn it on the lathe to get a smooth surface. It turned out beautiful.

  1. Wow I've been working with wood over fifty years ,,, you impress the hell out of me well done awesome job your like a pit bull

  2. His voice reminds me of an older version of Peter Draws' voice. His personality kind of mirrors his as well. Just wanting to dip your toe into every little hobbie to ever expand your experience with creative expression and creation in general.

  3. Make it a lamp and send the winner a preemptive letter letting them know they won and send it to them just before Christmas 🤣

  4. Museum quality work! One of the most interesting, lovely and innovative uses of a CNC and wood shop I've ever seen. With that much thickness I might have had the CNC label the larger parts for you.

  5. Wow!!! This is incredible!!! And your shop is amazing!! This was my first time watching you. My son bought me a lathe so I could turn my resin and wood crafts! I’m a beginner with the lathe ,and this project is way too advanced for me ,considering the tools you have ,such as the CNC alone is a tool I’ll never acquire 😢. I subscribed because I know I’ll enjoy watching you and sharing your channel with my older brother who does have these tools. He’s your age so i’m sure he’s got the skills you have. Your pretty amazing❣️❣️God bless you

  6. I think skills wise I would have a decent shot at replicating this, where I would fail is organization and patience, I would stare at this for days until I finally accepted the fact that I had spent way too much time making kinling and go back to making bowls.

  7. Frank, Two things: first, I have found that orange tape will adhere better and stretch just as well as green or blue w/o residue. Second, Using old brown glue instead of yellow or white aliphatic will make a better putty that will not show up on glue ups. Beautiful work and photography as usual.
