The third tape measure in the photos - the large one - involves an approach of my own devising, which incorporates the entirety (case and all) of a four foot tape measure with a cloth tape and a retraction button on the side. In essence, I "buried" the tape measure in the three-part wooden case (well, four parts if you count the button).
The small tape measure with the light-colored sides (the one that looks like a mini-burger) is turned from spalted birch (the 'buns'), and redheart (the 'burger'); it measures about 2" across an is 1" thick. It is finished with Watco Danish Oil - Natural, followed by buffed Renaissance Wax. The sides of the other small tape measure are turned from padauk, and the center ring from hard maple; it is just over 2" across and is only 3/4" thick. It is finished with buffed Renaissance Wax only. The large tape measure has padauk for one side, and purpleheart for the other, with hard maple for the center ring. Oh, the button - which is fully functional - is also purpleheart. It measures 2 3/4" across and is 1" thick. It is also finished with buffed Renaissance Wax.>
I constructed my trivets from four different woods (padauk, walnut, birch [I think] and a mystery wood [the lighter "orangish" one in the center]). The separate pieces were jointed, planed and glued together on their long sides, then re-planed. This long, flat blank was then cut into squares about 6 1/4" on each side. Then for each trivet two of the squares were glued together face-to-face, with the grain directions of the two pieces at 90 degrees to one another. After this, a miracle occurred.

Last week I did a demo and show-and-tell on multi-sided bowls for our wood turners club. This was our first meeting in our new location (the Monona Grove HS wood shop), and was well attended. I demonstrated how to turn one type of multi-sided bowl, and did a CD/slide presentation of all three techniques. I won't go into the turning details here, but will post some examples of each style of bowl - they are very different.
The first technique involves turning the multiple sides (three to as many as you can construct) by using off-center axes, and then turning the inside and outside of the bowl proper on the center axis. Here are examples of a 3-sided cherry bowl and a 3-sided walnut plate done this way:
The second type of bowl is a three-sided bowl that is turned from a precisely cut cube of wood. (This technique can be used only to turn a three-sided bowl.) Two opposing corners of the cube are cut off with a band saw sled having very exact angles, in order to mount the blank accurately between centers, and you go from there. Here are three examples: the painted ones are cedar; the natural one is birch.
The third style also can have as many sides as you want, from three on up. In this straight-sided design, the polygon is drawn on the blank (or on a glued-on paper template) and then the sides are cut off with a saw; accurate layout and cuts are essential. The bowl is then turned, preserving the straight sides. In the examples below (both cherry), the straight sides form the rim in the 5-sided version, whereas in the 3-sided bowl the wings have been "dropped" part way down the side of the bowl, and are also curved down.

Last week end my wood turning group had a two-day demo and class session with Mark St. Leger, a professional turner from Virginia, and an excellent teacher. Click here to see his web site.
On Saturday around thirty of us watched as Mark demonstrated how to turn a toothpick (!); carve and decorate a holder for it; turn an egg; turn an oblong endgrain box (with a natural end); turn a spherical box with chased threads (with wood-burned baseball lacing); and turn a three-sided "Rock-a-Bye Box." And, in this wonderfully packed day, he also showed us how to turn some jigs to assist in these projects.
On Sunday, seven of us returned for a hands-on class, in which we each turned a Rock-a-Bye Box, hollowed it, and turned a lid and a finial for it. We did not have time to fully finish-sand and apply finishes to our boxes, so the photos below show the project in its unfinished state. The box measures about 3" across and 1 1/2" high; the finial is 1" tall. The box and finial are hard maple; the lid is wenge.
The box is hollowed as far as I could reach with the tiny curved scrapers I brought along, but is still pretty hefty for its size. The idea of the "rock-a-bye" box is that it has a completely rounded bottom, so that it will rock back and forth when tipped, and the lid (which is turned slightly undersized) will slide from side to side in the opening, making a tick-tock sort of sound. The unusually shaped (golf club?) finial was turned on a jig that permits turning one end on two different centers, which allows the offset shown.
All in all it was a great couple of days!

I also turned a wine bottle stopper for them from one of the scraps of burl.
