After recently observing a demonstration in a local woodturning club, I had to turn an emerging bowl. This is the best way to hammer home what I observed. Then I can explore alternatives and combine features.
In this video, I went much further using green wood from a hazelnut branch removed in spring pruning. Squared lumber would have been an easier place to start but I am a glutton for punishment and went for a natural edge leaving the bark intact.
The limb was about 3 inches diameter. I initially cut it about 8 inches long. My process was:
- Prepare a waste block to fit my chuck. On the opposite side, I bored a hole for a mortise.
- Mount the limb and cut a tenon on one end.
- Glue together the mortise and tenon with Titebond II. Let dry overnight.
- Turn a perfect hemisphere on the end of the branch. Any imperfections will show up later.
- Saw the branch in half – a rip cut.
- Mount the half to a faceplate using hot melt glue and additional scrap blocks for support and security. The center of the bowl must be exact to the axis of rotation of the lathe.
- Relieve the new top surface leaving a small lip around the bowl. This is with the tail stock in place to ensure a good hold.
- Remove the tail stock and hollow the bowl.
- Clean up any remaining marks and edges by sanding.
- Finish with walnut oil.
Since the wood in green, I’ll keep it wrapped in plastic wrap and a paper towel to retard moisture loss.
The challenge in this project is mounting irregular wood, turning a perfect hemisphere, and turning off center wood.
Maybe I should have turned my first emerging bowl from dry square stock?? Yet, it turned out very nice.
