This is a technical drawing specification document for a Leadscrew Disposal Container (RF-2100, LIN 0001) produced by Portsmouth Naval Shipyard in Kittery, Maine. The drawing is part of a 22-sheet set and contains detailed specifications for the fabrication and assembly of a steel disposal container with a working load limit of 15,000 lbs.

The container consists of seventeen component parts, primarily fabricated from ASTM A36 steel, with supporting materials including stainless steel fasteners, O-rings, and hardware. Key components include a base plate, cavity pipe, center pipe assembly, cover assembly with handle and insert, lift blocks, and wall sections. The drawing specifies welding requirements per AWS D1.1/D1.1M standards, including minimum bevel angles of 45 degrees for single bevel groove welds and minimum weld sizes, with all welds to be performed by qualified welders and inspected per visual and magnetic particle testing standards. Fabrication includes surface finishing requirements with a minimum 125 RA finish, painting specifications using Amercoat 235 paint per MIL-PRF-23236 with two coats, and break all sharp edges to 0.03-inch chamfers. Comprehensive load testing is required with proof test values of 15,000 lbs applied to lift holes in the top plate, bottom plate, and lift blocks, followed by thread engagement verification, torque testing of cover cap screws at 120 +/-12 in-lbs, and post-test magnetic particle inspection. Documentation and permanent marking of the container with inspection due date (calculated as three years from proof test date minus one day) are mandatory requirements upon completion of all testing and quality assurance procedures.
