PRACTICE LAYUPS
FLAT LAYUP
.....
The first practice layup that you will make is a layup of six
BID plies onto a flat surface. This is intended to give you
experience in the techniques of glass/epoxy work and to give you a
check on your workmanship. You should be able to complete this layup
in about half an hour. Protect your work bench by taping waxed paper
over an area about 24" by 24", (or, find a piece of metal and wax its
surface). This will keep the epoxy from bonding to the table top. Cut
six plies of BID that are about 12 1/2 inches by 18 inches.
.....
Laminate the six plies on top of the waxed paper. Try to do your
best job of stippling and squeegeeing so that the plies are
completely wetted but not full of excess epoxy. Let the layup cure to
knife trim, about four hours. Carefully mark a 10 inch by 16 inch
rectangle and knife trim the layup to that size using a sharp razor
blade or trim knife. Allow the layup to cure completely. If you
forget the knife trim, cut the cured piece with a coping saw or band
saw.
.....
Take the cured 10"x16" piece to your post office, or any
accurate scale, and ask them to weigh it for you. Your laminate
should weigh between lO 1/2 and 12 1/2 ounces. A 10 1/2 ounce layup
is about as light as can be done without voids (white areas). A 12
1/2 ounce layup has too much resin, and if you make all of the 1ayups
in the airplane this wet, your Q2 may be as much as 50 pounds over
weight. An 11 ounce layup is just about perfect. Save this piece; it
will be useful to check future 1ayups against.
