|Depending on the scale and whether the model
is precise to a given scale. Balsa and Basswood triangle stocks are
available from architectural and hobby suppliers
which when glued to a surface to replicate raised corrugation their shape edge is rounded over appropriately and faired in at each end to provide surface onto which
to place Flite-Metal beginning from the midpoint down the length of the raised balsa or basswood working toward the leading & trailing edge of surface proportionally
along a virtual midpoint line dividing the width of the surface.
Contact with surface is only on top of raised balsa or basswood...not between rows at this point. Using an appropriate diameter fibrous burnishing stump, place the
side of the stump between each row, beginning at the center...half way across the surface. Repeat outward one additional row at a time in opposite directions until
the aluminum is pressed gently to the surface but not with too much pressure. A little pressure will go a long way.... When half the fore~aft length of raised balsa or
basswood is covered, repeat in the other direction being careful to no press down beyond the length of each individual raised section.
Your previous experience with heat shrink modeling coverings comes
into play at this point as you will adhere a gripping strip of
hardwood or ply about 1/2 inch wide
