MCW Sept. '11 Demo
Sep 13, 2011Public
Photo: Mike Kehs started off the demo by passing around some examples of what he means by Very Thin-Walled Vessels and ...
Photo: taked about his finished show and tell items, this one with with flames ...
Photo: ... and this one detailing his other passions, caves and bats.
Photo: Mike shows his modification to his roughing gouge with the sides ground back....
Photo: ... so that he can use it to put a tenon on the roughed out blank.
Photo: Mike demonstrated in his initial shaping of the bowl how he puts his fingers under the rest for support.  He supports the tool with his thumb on top of the tool.
Photo: He measures the depth he wants the bowl to be and grips the drill bit to mark the spot.
Photo: He then drills to the correct depth, not worrying about going slow but cleaning out the chips when they start to fill up the groves.
Photo: Mike explained that in the old days this end grain blank would have been cleaned out with a scraper.
Photo: Then he showed that the Termite tool works very well on end grain.
Photo: The only way that the termite works is at an angle a little less than 90.
Photo: The big chips fly free...
Photo: ... and easy!
Photo: Mike then explained that he almost always grabs his bowl gouge to clean out the bowl.
Photo: He does not start in the center and work out like many profess, and he does not expect a clean cut but rips out chips fast.
Photo: Mike says to keep a funnel shape and get the top of the funnel the correct thickness and then make the funnel smaller. This method keeps to the rule, cut to finished thickness in depth steps, and don't go back to retouch the thin part.
Photo: "Measure often" was his motto.
Photo: He moved the rest inside the bowl to get more support and cut the walls pretty thin.
Photo: Ok, rules are made to be broken! Here he goes back with the scraper to take a little more off.
Photo: Mike uses his wood shavings as insulation for his fingers while he supports the outside of the bowl.
Photo: Measure often! Here he figures out where he needs a little more off. As with any good demonstration, he will do things on the side closest to the audience whenever possible.
Photo: Mike uses a home made tool to find the depth of the bowl. He drilled a hole for the dowel and one for the tightening screw. He then cut a slit down the middle of the board to the hole for the dowel.
Photo: After he measured the base of the bowl inside, he then marks where he wants the outside base of the bowl.
Photo: Not all of his tools are purchased. Here he shows a band saw blade he uses to part with. He uses it to mark where the bottom of the bowl will be.
