About this file
This is a technical drawing for a 2.54M Buoy Bridle Assembly, document number ATBDL2.0-F1001, prepared by the National Data Buoy Center at John C. Stennis Space Center in Mississippi. The drawing is a two-sheet engineering blueprint showing the complete assembly specifications for a bridle system used on a 2.54-meter buoy.
The assembly consists of 13 component items including three bridle leg isolators, one pendant isolator plate, one bridle weldment, three nylon-insert hex locknuts in .375"-16 thread size, three cap screws (.50" 13 UNC x 3.50" long), six flat washers (both stainless steel and nylon), three zinc anodes for the bridle, three lead weight bricks (2.00" x 4.00" x 8.00"), and additional fasteners including machine screws and washers. Most materials specified are 316 stainless steel for corrosion resistance in marine environments, with several components sourced from McMaster-Carr. The drawing includes front, side, and exploded views at various scales (1:1 to 1:5), detailed dimensions with tolerances (decimals ±.05 to ±.010 inches, angular ±.5 degrees), and specific fastener specifications. All components are identified by part/specification number and vendor information, making this a comprehensive fabrication and assembly specification document.
