held in place by inserting a conventional machine screw 6 through the hole 3 in the flange 5 and tightening the machine screw 6 into the threaded insert 4 in annulus 1 the threaded insert 4 and machine screw 6 can be made of virtually any material normally used in the manufacture of such parts but given the nature of this application a corrosion resistant material such as brass nylon or stainless steel would be preferred the present invention functions as shown in fig6 and 8 once the attachment means is released the insert 2 is free to be removed from the annulus 1 a piece of decorative material 20 is selected and cut to fit over the top face 7 and radiused surface 11 39 of the insert 2 the cutting of the decorative material 20 can be accomplished by many means such as using a supplied template using a previously cut piece of decorative material or using the bottom shape 10 39 of the insert 2 as a template fig7 amp 8 show how the decorative material 20 after being cut is placed over the top face 7 of the insert 2 in such a manner that the decorative material 20 evenly covers the top face 7 and the radiused surface 11 39 of the insert 2 optionally adhesive material 13 can be placed onto the top face 7 of the insert 2 to temporarily affix the decorative material 20 to the insert 2 during assembly any quantity of adhesive material 13 in virtually any shape can be used but in this embodiment the adhesive material 13 is applied in two rectangular strips as shown in fig9 once the decorative material 20 is correctly positioned on the insert.
