I’m still having a ball turning spheres! This is how I turned a hollow sphere. I first mounted a piece of wood about 3 1/2″ square by 5 1/2″ long between centers and turned it round with tenons either side sized to fit my jaw chuck. I measured the diameter of the cylinder at the center point and it was 3 1/4″. I then parted the cylinder in half.

I’m pleased with how it turned out. The contour is very smooth which is something I’ve been working towards with my bowl turning.
If you are interested in buying one of these tools they can be purchased at Woodchuck Lathe Tools I am waiting on arrival of two tools a friend is making up for me. They are for lathe work and accept radius carbide cutter inserts. The tools are made from some 1/2″ x 1/2″ x At the demo by Fred Holder I attended he turned a sphere and used a set of sphere calipers. They are available online, but are pricey, so I did some more searching and found a great article by Al Hockenbery. It involves a bit of math but is a fairly quick and easy way to turn a sphere on the lathe. This article describes and illustrates the process. I’m having a lot of fun turning these spheres and have also decided to start a wood collection and am going to turn my collection into spheres! One of the nice things about the spheres is that they show off the end, face and side grain in a small area. They also look so cool and feel so good to hold! If anyone else is doing this already or is interested in starting I’d love to hear from you. If you’re interested in trading wood to make spheres or trading the spheres themselves let me know. I find a nice size piece of wood to start with is 3″ x 3″ x 4 1/2″.
You can click on any of the images to see a larger version. This is the latest pen I made. It is a new design, I call it “Unraveled”. This pen is made from Mesquite with aluminum inlays. The pattern repeats four times around the pen and lines up whether the pen is capped or posted. If you would like to see more of my segmented I needed to make a donut chuck so that I could mount a 12″ bowl on my lathe and finish off the bottom of the bowl. I have a set of cole jaws for my jaw chuck, but they will only expand 10″.
You can click on any of the images to see a larger version. I have a project coming up where I need to be able to mount a face plate accurately to a work piece. So I made a center finder for my face plate. You can buy really nice ones made out of aluminum but it took me about ten minutes to make this one. I At the hands on session I attended with Fred Holder my goal was to learn how to turn a perfect sphere. I did two that day, one out of poplar and a second out of mesquite. Since then I’ve done a few more. I’ve made spheres out of cherry, birch and spalted sweetgum. I’m I had the opportunity to photograph some bowls turned by Gene O’Donnell from wood that I supplied him from Zambezi Exotics. Gene is a member of my Woodturning Club and does beautiful work. He normally embellishes his work with carving, texturing and pyrography. The first bowl is from Zambezi Teak. The color and |
