Bullnose is a term used in building construction for rounded convex trim, particularly in masonry and ceramic tile. [1] It is also used in relation to road safety and (formerly) railroad engineering design.
The pencil is robust and strong to endure heavy duty environments like a tool box, construction site, or carpentry shop. [2] The core is typically stronger than in other pencils. As such, carpenter pencils are often used by builders because they can mark on surfaces like concrete or stone. The shape and lead density aid in marking legible lines ...
A bullnose shoulder plane. In this model the mouth is adjusted by adding or removing shims behind the removable nose.. The shoulder plane (also bullnose plane) is a plane tool with a blade flush with the edges of the plane, allowing trimming right up to the edge of a workpiece.
In India, the most common pencil colour scheme was dark red with black lines, and pencils with a large number of colour schemes are produced. [80] Pencils are commonly round, hexagonal, or sometimes triangular in section. Carpenters' pencils are typically oval or rectangular, so they cannot easily roll away during work.
Pencil milling is a cleanup toolpath generated by computer-aided manufacturing (CAM) programs to machine internal corners and fillets with smaller radius tools to remove the remaining material that are inaccessible with larger tools used for previous roughing, semi-finishing, and finishing toolpaths. The name comes from the way that a pencil ...
Solid hardwood is more prone than engineered timber to "gapping" (excessive space between planks), "crowning" (convex curving upwards when humidity increases) and "cupping" (a concave or "dished" appearance of the plank, with the height of the plank along its longer edges being higher than the centre) with increased plank size. Patented ...
Quarter round molding at the edge of a parquet floor. A quarter round is a convex molding whose cross section is a quarter circle. It is one form of ovolo. A variation is a base shoe, a quarter of an ellipse. [1] Most quarter round is of small gauge and relatively flexible.
A mechanical pencil or clutch pencil is a pencil with a replaceable and mechanically extendable solid pigment core called a "lead" / ˈ l ɛ d /. The lead , often made of graphite , is not bonded to the outer casing, and the user can mechanically extend it as its point is worn away from use.
