Description

A wooden beading plane consisting of 3 parts.
a- The body is rectangular and made of a light brown hardwood. A cheek protrudes from the bottom 2/3 of the front of the body. A long mouth cuts through the centre of the cheek and slopes down toward the toe. The sole is curved concavely in a parabolic form. A skewed fence closes the curve. Stamps on the toe read: "J.DRYBURGH/BRIGHT.ONT"; "I BLOWER". Stamps on the heel read: "I BLOWER"; "3/8".
b- The wedge is made of the same hardwood as the body. It tapers to a blunt point on one end and is chamfered on the other. A rounded cut-out allows for easy handling.
c- The iron is a narrow strip of grey metal. It is wider near the cutting edge. The cutting edge is curved concavely in a parabolic form. The width of the cut is 3/8".

History

A less common variation of the bead plane is the torus bead or the astragal. The difference is that on a regular side bead, the bead is cut with only enough material removed on the inside of the cut, to shape the bead. With the astragal there is extra material removed on the inside of the cut so that the bead stands out.
