The foam blanks have two smooth sides and two rough
sides. We will work with smooth sides.
Lay one of the foam blanks on the bench with a smooth
side up.
Measure ½ inch from the bottom edge. Use the included
square to draw a line down the end of the block.
The line should go all the way from the bench to the top
of the block as shown.
Be sure that the square is flat against the bench. This is
important.
Repeat on the other end.
Be sure to measure from the same edge.
Bring your marks around the corner so you can see them.
Grab both Insides (marked INSIDE). Note that one side is
curved and one almost straight. The curved side is the top.
On the side marked with INSIDE, put a piece of masking
tape over the slots near the front of the inside.
This is needed to prevent glue from getting in the slots
that are used later.
Tape each one. Be sure to do both pieces on the marked
side. Use regular masking tape. We only used the blue
low tack for the pictures.
Pin both insides (INSIDE) to
one
block of foam. Line up
the back so that they are even with the foam.
Line up the bottoms of (INSIDE) on your marks on both
ends.
Be sure that both parts are perfectly aligned with each
other. Look at both ends and double check.
Photographs of very light colored ply on white foam are
difficult to see. We will use some drawings to make
things more clear.
