As you can see the first maple segment is cut for this segmented woodturning project. The dimensioning of the material has been taken care of and the 80 tooth sawblade of the compound miter saw has the necessary angle. A Wixey digital gauge is used to ensure the accuracy of the sawblades’s angle. The stop-block on the right is clamped into place to maintain a consistent width for the segment. (Note: Use a scrap piece to test the accuracy of the segment’s angles. This is accomplished by cutting 1/2 the amount of bowl segments and taping the outside perimeter with the joints perfectly aligned. If the miter angles are correct then the two outside angles will be completely flat on a solid surface such as a table saw as is pictured below.)
Now it is a matter of taking the time to allow for each segment to be cut. There are 12 maple segments for each small dinner salad bowl and a total of six small bowls. While the compound miter saw set in this position we’ll make all 72 maple segments for the smaller bowls. Just to be safe we’ll also make a few extra segments. One large tossing bowl will be made later as well however, the widths of the segments will be greater and will require an adjustment of the stop block.
The walnut spacer is just under an 1/8″ and it is sanded flat, smooth, and parallel. It’s now ready to be ripped. The width is determined by measuring across the maple segment’s angle. For example if the thickness of the maple segment is 3/4″ then the measurement across this angle will be somewhat greater then the 3/4″ thickness. We’ll set the tablesaw’s fence to this dimension and rip away.
Once the spacers for the segmented woodturning are ripped it’s time to cut them to length. It easy enough to do by hand and sometimes it’s nice to take a break from the power tools.
Masking tape is quite useful in this operation. It’s on the opposite side of the segments pictured to the left. The tape is holding the alignment of the segments so that the walnut spacers can be sandwiched between the maple segments. So now, it’s time to add glue. We are using Titebond 2 for this segmented woodturning operation. We want to make sure we apply enough glue in the joints! It’s a one-time shot.
Pictured at the right are glued segments that form two halves of a bowl . For the moment masking tape and rubber bands apply enough force to allow for a bit of glue to set. This also gives us time to grab an adjustable metal hose clamp to secure the segmented woodturning.
To the left is an example of the segments being tightened with the use of the large adjustable hose clamps. We use a socket driver on the cordless drill to take up most of the slack and then we finalize it with the hand driver. You’ll notice a few shims under the circle of segments. Sometimes an adjustment is needed to maintain uniformity in the alignment of the segments. So now it’s just a matter of tapping here and there with the hammer. (The larger tossing bowl is pictured to the left.)
