When we started making bowls, our goal was to use highly figured wet wood to sculpt them into a variety of shapes, sizes and aspect ratios. We started with a lathe but were frustrated that the lathe’s requirement for making round objects did injustice to some of the most evocative features in many pieces of wood. We learned from our lathe work that our choice of using the most dramatic, wet wood meant that we must be able to accommodate warpage from drying. Lathe turners twice turn their wood, first rough carving and then allowing the bowl to wood to equalize stresses through drying and then turn the bowl again using the fixed axis of the lathe to re-enforce symmetry. We needed a carving process that duplicated the twice carving approach, but which was reliable, quick, and easy to use. This led to a systematic approach that had three components: 1) A set of simple design protocols to create reproducible designs for several categories of shapes that were based entirely on the rim, 2) A set of carving rules that maximized the ability to easily recover the original design after warpage, 3) Several procedures that enable the quick and reliable execution of symmetrical bowls with thin and uniform rims and wall.
While there are many written and video tutorials on bowl carving, none were suited to carving finely crafted, symmetrical bowls from wet figured wood. For example, ovals were typically designed by the two-pin method, which is fine for dry wood, but is unusable for the bowl’s redesign needed for the second carving because the hollowed-out bowl no longer offers a place to mount the pins in their original position. Rim-only design is required, so we had to develop an alternative approach and then take that lesson to the other bowl shapes.
Many people have asked how we do this, so we have created our own tutorials to guide others that are enamored with highly figured, interesting wood.
Below are two items:
First is a Step by Step guide to carving wet wood into symmetrical, finely crafted bowls. It is intended as a quick reference to the YouTube series.
Second, is an introduction to the Nicasio Oval, a protocol specifically created to draw ovals for carving warp-prone wood. This file describes the Nicasio Oval's rim-based design for designing reproducible ovals of any size or aspect ratio. This document also outlines the geometric theorems that guarantee the ease and accuracy of drawing centerlines for orienting handles, feet or other embellishments in both the wet-rough carving stage and after the newly dried, but warped bowl is ready for finish carving.
