Barley Twist Flutes and Spirals
Barley twist flutes and spirals are an "old world" pattern used mostly for table and chair legs and as decorations on furniture.
These have been done laboriously by hand until now, except for costly machine or CNC types of equipment. The Spiral Master provides a way to cut barley twists on both straight and curved profile turnings in minutes instead of hours.
You can purchase a barley twist router bit from Flute Master as part of a set of six most commonly used router bits. A special Proximity depth guide is included for the wider router bit.
The Barley Twist router bit is aggressive, so make multiple light cuts. The best way to do this is to set the depth guide with a beginning shallow cut, then increase the depth. This bit should be cut in spirals 30 degrees apart (using the index wheel "B" ring, cut every 4 holes), or 36 degrees apart (every 6 holes on the "A" ring). Example below is cut on 12.6 inch pitch. They can also be cut in 6.3 and 9.8 inch pitches.
River Birch 1 3/4 by 14 1/2 inches.
Note: This bit requires a special Proximity depth guide available from Flute Master.
Barley Twist does not lend itself well to curved profiles with a large difference in diameters.
