In looking for new prospects for scrolled bowls, I found two other ways to simulate the kinds of segmentation related to lathe-turned bowls.
Each strategies are straightforward to study and much much less demanding than conventional approaches. The primary produces segmented bowls with stable sides; the second creates open segmentation.
Segmentation with Strong Sides
My methodology for creating the sort of bowl eliminates the necessity to reduce many small items at exact angles. As a substitute, it depends on stack reducing, a typical scroll noticed approach, to create the clean.
The fundamentals are easy: two contrasting blanks, sometimes between 1/4″ and 1/2″ thick, are hooked up with double-sided tape. A sample, consisting of a circle divided into a delegated variety of segments, is hooked up; the circumference and segments are then reduce to form.
As soon as reduce and numbered, alternate segments from every set are exchanged to kind two multi-colored circles. As a result of all items are stack reduce, deviations in any piece are compensated for by complementary deviations within the adjoining items.
The segments are glued at their edges to kind two circles and sanded evenly as soon as the glue has set. They’re then glued collectively to kind the clean.
The clean can then be reduce in the identical manner as any scrolled bowl, or rings reduce from it may be used as ornamental parts in a multi-blank venture.
It was difficult to design a clean that might appear to be open segmentation when reduce into rings, however the resolution turned out to be fairly easy. The clean is constructed from wedges reduce from a circle, then glued evenly round a skinny substrate.
A sample is hooked up to the substrate aspect and the rings are reduce at predetermined angles. The reducing course of creates rings with an everyday sample of slices and areas.
Relying on measurement and function, the bowl will be reduce in order that the wall thickness stays uniform all through, or reduce in order that the wall thickness will increase barely with every successive ring.
Partitions of even thickness are perfect for smaller bowls, particularly these which can be primarily ornamental, whereas these with rising wall thickness have a larger gluing floor — a consideration for bigger bowls or these supposed for normal use.
Sanding of an open segmented bowl is normal, with two notable exceptions. First, care should be taken to keep away from catching the sander on the perimeters of the segments; the slits on the backside of the spherical inflatable sander are particularly weak. Because of this, I exploit the smaller of the 2 inflatable sanders: the openings of their abrasives resist snagging higher.
Second, the middle part of the clean, normally used as the bottom, has wedges on its underside. These should be sanded off for the piece for use. If this isn’t possible, reduce a brand new base from the identical wooden because the substrate.
Variations to Discover
This versatile methodology for open segmentation can be utilized for rounded sq. and wavy bowls as simply as for spherical ones. With a slight sample adaptation, it may even be used to make oval bowls whose segments stay evenly sized throughout the circumference.
When you’ve mastered the method for making a primary scrolled bowl, it’s a straightforward transition to variations that nobody will consider had been made with a scroll noticed.
