MCW April '14 Program
Apr 30, 2014Public
Photo: We are once again privileged to have David Ellsworth as our demonstrator.  Our newly appointed digs are all set up and ready to go...
Photo: ...including the overflow area that makes good use of our new 55" HD monitor.
Photo: What's the first thing you do before turning?  Yep, sharpen your tool!
Photo: In his demos, David teaches a wide range of subjects, including safety, sharpening, tool selection, tool use, stance, procedures, and lots of technique.  He presents all of this information within the umbrella of turning two bowls -- the first, a "cut edge", and the second, "natural edge" or ("bark edge").  For this one, the bark goes to the tailstock side and will be removed.
Photo: David gets his face shield on to even talk about putting tool to wood.  Here, he describes the proper angle of approach with his "signature" bowl gouge.
Photo: We have provided David with a side-grain round of liriodendron tulipifera (tuliptree, a.k.a. "yellow poplar").  Let's make some shavings with a roughing cut.
Photo: Bert Bleckwenn watches the action on his audio/video masterpiece, while Matt Radtke has the tailstock camera on the screens.  Thanks, Bert, for all your work that brought these wonderful capabilities into being.
Photo: Now that we can see what's inside, it's time to adjust the orientation to get the grain patterns balanced in both directions.  Note the pencil mark.
Photo: It seems to be pretty straight already.
Photo: Let's get rid of some more waste wood, first.
Photo: Now we'll adjust the location of the live center point by one-half of the change we want.
Photo: Let's rough this on it's new orientation and see how it looks.  Right on.
Photo: Adding a tenon for later chucking.
Photo: I'm using just this part of the edge of the tool.
Photo: Finishing up the tenon, as seen on the monitors.  We want a perfect corner whose shape matches that of the chuck jaws.  A spindle gouge is perfect for doing this.
Photo: We have a high spot here that needs to be removed.
Photo: We have now reversed the piece and clamped the tenon in the chuck jaws.
Photo: Flattening the top with a pull cut.
Photo: Making a "base cut" that will leave room for the ultimate real shape of the bottom of the bowl inside of it.
Photo: The bottom will curve in like this and may actually go down inside the tenon.
Photo: The shavings are piling up!
Photo: Time to start hollowing; we'll work at the center first, cutting from outside to inside.
Photo: A nice aggressive "production" cut to get that middle out of there.  Note that this cut is done with the hand away from the body and the flute nearly horizontal to prevent initial runback.
Photo: Another entry cut near the rim.  Move that wood out.
