Plate 142:  Adding a souvenir mug to the collection, Part 28: completing the ogee curve for the handle's receptacle
(This plate added OCT 2004)

Here we see the back of an unlaminated quarter-inch strip of boxboard that has been fashioned into an ogee curve. Plates 137 and 141 show earlier views of this same strip of boxboard, before the curve was completed. (Plate 141 contains information on ogee curves.) The right-hand photograph in Plate 141 shows the back of the strip, as does the view shown here. However, in Plate 141, the back of the strip was in shadow, while in this view the back of the strip is illuminated, revealing colored printing on the claycoated side of the strip (see Plate 129 for a discussion of claycoated boxboard). --more--

The printing that is visible on the back of the strip reveals that the source of the thin boxboard was a carton that had contained file folders with a 3/4-inch capacity. We made no attempt to conceal the printing, because the claycoated-back of the strip will not be visible when the presentation box is completed. The white glue being used to affix the curved strip to the edge of the cut-out is made from polyvinyl acetate (PVA). This inexpensive type of glue is available in the stationery department of any discount store. Observe that the glue is an opaque white liquid when it is first applied. However, PVA glue shrinks into a semi-transparent condition when dry. PVA glue is highly adhesive when applied to boxboard. When wet, PVA glue can be easily removed with a damp cloth or paper towel. When fully dried, however, the only practical way to remove PVA glue is with a sharp knife, such as a modeler's knife. If it is necessary to remove dried PVA glue, the removal must be performed with great care in order to avoid damaging the surfaces which have been glued. Go to top of page
