Abstract:
1. A method for positioning and joining together first and second sheet panels, comprising: providing a support having a locating pin; extruding a first hole in the first panel with an annular upstanding wall surrounding the hole, said first hole having a diameter sized to fit closely over the locating pin; forming a second hole in the second panel that has a diameter sized to fit closely over the annular upstanding wall of the first panel; placing the first panel upon the support with the first hole of the first panel fitting on the locating pin; placing the second panel atop the first panel with the second hole of the second panel fitting onto the annular upstanding wall; and creating a bond between the first and second panels adjacent to the annular upstanding wall, so that the annular upstanding wall protects the locating pin from being fouled by the bond.
