    摘要: A dual use repeat builder assembly comprising a multiply inner sleeve with a bond layer surrounding its outer diameter for securing a compressible foam layer to the outer surface of the inner sleeve. A hard foam core is formed around the compressible foam layer using a mold cavity. After curing, the mold is removed and the ends of the hard foam core are machined creating cavity regions at each end. A notch insert is positioned at one or both of the cavity ends. A polymeric resin is poured into the cavities to form end caps. The outer surface of the hard foam and the end caps is machined to produce a smooth surface. An outer sleeve is mounted onto the hard foam core using compressed air with a resulting interference fit between the outer sleeve and the hard foam layer. Location of the end caps are such that holes can later be drilled through the wall thickness to convert the repeat builder to a bridge mandrel to enable mounting of thin sleeves to its outer surface. After extended use and wear, the outer sleeve can be removed by expanding it with air and replacing it with a new outer sleeve thus extending the useful life of the unit and/or modifying its outer diameter.
