Here are the steps I use to make segmented bowls. The first step show a piece of purpleheart 28” long
Next I adjust the table on my Shopsmith to 22.5 degrees.
This picture shows the purpleheart board cut with the 22.5 degree angle on the edge. This step is very important. If this angle is off everything else after this step will be affected.
Next I cut the 28” board into 8 3” sections
Here I am gluing the pieces
I use a piece of a rubber intertube wrapped tightly around the bowl to hold the pieces together while the glue dries.
Now I cut a piece of wood for the bottom and glue it on.
After the bottom is on, I locate the center of the bottom so I can glue on a piece of scrap wood attached to a faceplate. I insert a piece of newspaper between the scrap and the bowl. This will make removing the scrap piece easier later on.
Now the bowl is attached to the lathe and it’s time to turn.
I have finished the turning and sanded the bowl to 220 grit
The finished project. I applied 8 coats of Tung Oil finish. I leave the faceplate attached to the bottom of the bowl until I finish applying the finish.
