Bias tape or bias binding is a narrow strip of fabric, typically plain weave, cut on the bias. As the weave of fabric is at a 45-degree angle, the resulting fabric strip is stretchier than a strip cut on the grain. The strip also has a better drape, and conforms to curves better than fabric cut on the grain. [1] Bias tape typically comes with ...
Diagonal- and stepped-cut rift-sawing is intermediate to flat-sawn and radial cut lumber. The angle of the bastard grain may differ along the width of the board or between opposing sides, and enhances the appearance of ray fleck. Flat-sawing is the quickest method, producing the least wood waste and largest possible boards from a log.
Quarter sawing is sometimes confused with the much less common "rift sawing." [4] [5] In quartersawn wood, only the center board of the quarter-log is cut with the growth rings truly perpendicular to the surface of the board. The smaller boards cut from either side have grain increasingly skewed.
Non-woven fabrics such as felt or interfacing do not have a bias. bias tape Bias tape or bias binding is a narrow strip of fabric, cut on the bias. The strip's fibers, being at 45 degrees to the length of the strip, makes it stretchier as well as more fluid and more drapeable compared to a strip that is cut on grain.
Rip cut comes from rip: to split or saw timber in the direction of the grain, and cut: to divide with a sharp-edged instrument. [1] Wood may also be split along the grain (riven), but the split will follow the grain and usually not be flat. Knots also prevent riving thus the need for rip cuts. A kerf is the opening in the wood made by the saw.
Lumber can be quickly flat-cut with a side-by-side set of mechanical saws. [3] A slower but sturdier method involves passing the log back and forth over a single saw. To reduce buckling that may occur along the middle of flat-cut boards, the initial cut may be offset from the diameter, and resulting sections cut further before cutting the flitches.
Extra wide double fold bias tape being sewn as a binding for a decorative quilt. In sewing, binding is used as both a noun and a verb to refer to finishing a seam or hem of a garment, usually by rolling or pressing then stitching on an edging or trim. [1]
Vertical saws have two cost types, low cost and higher cost. Both types have the saw traveling through the short side of the sheet called cross cutting. For cutting lengthwise (rip) cut, the lower cost models, have the user slide the material through the saw while the higher cost models have the saw travel through the stationary material.
