Developed by Piper engineer David Long in 1948, plans for production by Schweizer were underway at the time of Long's death two years later. All rights and tooling were purchased by Robert Bushby in 1959, who built a 90 hp Continental-powered example and sold plans and kits until 1992 [ 4 ] when the rights were sold to Mustang Aeronautics.
High ozone shock treatment or ozone blasting is a process for removing unwanted odour, and killing mold, vermin and microorganisms in commercial and residential buildings. . The treatment is less expensive than some alternative methods of sterilizing indoor spaces - cleaning or removal of building material, or in extreme cases the abandonment of sick buildin
Robert Wesley Bushby (February 24, 1927 – October 14, 2018) was an American aircraft mechanic and aviator who designed the Bushby Mustang II, later called the Mustang Aeronautics Mustang II. He was born in Joliet, Illinois , and started to learn to fly while in high school in Minooka, Illinois .
Plaster and other chemical curing materials, such as concrete and plastic resin, may be cast using single-use waste molds as noted above, multiple-use 'piece' molds, or molds made of small rigid pieces or of flexible material such as latex rubber (which is in turn supported by an exterior mold). When casting plaster or concrete, the material ...
Its 24.2 ft (7.4 m) span wing employs a NACA 64A212 airfoil at the wing root, transitioning to a NACA 64A210 at the wingtip. Standard engines used include the 150 to 160 hp (112 to 119 kW) Lycoming O-320 , the 180 hp (134 kW) Lycoming O-360 and the fuel-injected 200 hp (149 kW) Lycoming IO-360 four-stroke powerplants.
Some foundries use robot autogrinders to remove this unwanted material. It is very typical for molders to have their operators trim flash with hand tools at the molding machine between cycles. Many molders and OEMs seek out the use of batch processes including vibratory tumbling, cryogenic deflashing [ 4 ] or media blasting to remove unwanted ...
Cores to accommodate holes can be seen in the bottom half of the mould, which is called the drag. The top half of the mould is called the cope. In casting, a pattern is a replica of the object to be cast, used to form the sand mould cavity into which molten metal is poured during the casting process. Once the pattern has been used to form the ...
However, in shell mold casting, the mold is a thin-walled shell created from applying a sand-resin mixture around a pattern. The pattern, a metal piece in the shape of the desired part, is reused to form multiple shell molds. A reusable pattern allows for higher production rates, while the disposable molds enable complex geometries to be cast.
