By cutting from the side, the grain is always face grain |
After truing, Jim starts the shaping from the bottom towards the top |
Jim cuts the bottom for mounting in the chuck when it's reversed |
With a pencil mark to show his minimum thickness in the chuck area, he continues shaping |
|

Jim demos the differences between cutting and scraping |
The chuck is mounted and the trueness is checked before disengaging the faceplate |
The bowl is reversed, mounted in the chuck, and the faceplate screws are removed |
Jim trues up the top side of the blank to create the rim |
|
|
|

|
After establishing the rim, he begins the hollowing process |
Jim explains the technique of thinning the walls progressively to minimize chatter and flexure |
The hollowing continues showing the progressive wall thinning concept |
Jim gets to a point where the gouge can't be used anymore because of the angle of the grind |

Showing the ways to measure the depth of the bowl to avoid making funnels |
Using pencil marks to highlight areas requiring attention, Jim puts the finishing cuts on the inside |
Just a quick bit of sanding and the piece is complete |
With all kinds of tools for wall thickness, the fingers are probably the best to sense differences |

The finished demo piece is passed around for closer inspection |
After fielding questions, the group breaks up for cleanup |
With many lending a hand, the cleanup goes pretty quickly |
The cleanup finishes and everyone takes off |
