Therming
Therming is a technique used by woodturning, woodturners to simultaneously create multiple copies of spindles and table legs. Often described as off-center spindle turning, therming is also known as drum turning and barrel turning. Therming allows a woodturner to make exact duplicates of three, four or however many spindles a therming rig can hold. Figure 1 shows multiple identical, partially completed spindles mounted on a therming rig. Note that all outer surfaces of the items being turned are curved. By rotating each spindle in the therming rig, all of the sides can be turned to individual contours to create unique shapes. For a four-sided turning, each side would be rotated 90 degrees after completing a side. Each spindle must be rotated the same amount in the rig to maintain similarity. Shapes with three, four and five sides are typical. Historically, the technique was used to produce table legs and balusters, usually with four sides. Therming dates back to the 18th Century a ...

Woodturning
Woodturning is the craft of using a wood lathe with hand-held tools to cut a shape that is symmetrical around the axis of rotation. Like the potter's wheel, the wood lathe is a simple mechanism that can generate a variety of forms. The operator is known as a turner, and the skills needed to use the tools were traditionally known as turnery. In pre-industrial England, these skills were sufficiently difficult to be known as 'the misterie' of the turners guild. The skills to use the tools by hand, without a fixed point of contact with the wood, distinguish woodturning and the wood lathe from the machinist's lathe, or metal-working lathe. Items made on the lathe include tool handles, candlesticks, egg cups, knobs, lamps, rolling pins, cylindrical boxes, Christmas ornaments, bodkins, knitting needles, needle cases, thimbles, pens, chessmen, spinning tops; legs, spindles, and pegs for furniture; balusters and newel A newel, also called a central pole or support column, is the cent ...
