to make the empty shell 11 first then fill it with foam in the ends 16 and 17 thereof and then to force the tubular reinforcing element through the foam at one end of the composite spindle and ram it into the other end thereof as depicted in fig2 and fig3 a the polyurethane foam injected into the end sections 16 and 17 of the pvc outer shell 11 can be injected at a controlled rate and in a controlled amount to control or limit the amount or extent of the filling of the end sections 16 and 17 with polyurethane foam a depicted in fig2 and 3a sufficient amounts of high density polyurethane foam can be injected into the interior of the end sections 16 and 17 to ensure adequate securement of the steel tubular reinforcing element within the pvc outer shell alternatively as depicted in fig3 b additional liquid polyurethane foam can be added to the end sections 16 and 17 to fill the end sections 16 and 17 substantially completely with polyurethane foam indeed as depicted in fig3 b a small amount of the polyurethane foam can be allowed to escape beyond the end sections 16 and 17 and into the intermediate section 18 fig3 a and 3b depict that the high density foam can be used to fill the end sections only half way fig3 a or entirely fig3 b the resulting composite spindle has the appearance of a turned wooden spindle without the attendant demand on timber resources for producing such moreover the cost of manufacturing such a composite spindle is.
