At the invitation from fellow woodturner, Sam Angelo, I turned this 2″ by 7″ tube from fresh wet cherry. This project is fun because when the turning is finished, I go to the microwave to heat it up. With a couple of excursions through the over, the tube warps and takes a shape of its own. The shape is only somewhat predictable.
The wood blank is cut cross grain from one half of a log at one side of the pith.
My process is:
- Rough turn and cut a tenon on one end.
- Reverse mount
- Finish rough turning
- Refine exterior.
- Drill and hollow from one end. Best tool for this task is a square corner box scraper.
- Reverse the wood into deep shark jaws. Some protection for the exterior may be in order.
- From scrap, turn plugs to fit both ends of the tube.
- Remount between centers and refine the exterior. Remove any marks and defects. Reduce to desired wall thickness.
- I cut beads on the exterior to further refine the exterior and to reduce the wall thickness. The thinner the wall, the more it may warp.
- Wrap packing tape around both ends wrapping tape around into the inside. This protects the ends from drying too quickly and catching fire.
- Microwave on high for a minute. Remove and check progress.
- Repeat until the wood is dry.
- Optionally, add finish.
My DIY steady rest and new box scraper came in handy for this project
