have selected light weight fiber glass cloth for use in this process. When I say light, I
mean between .6 to .7 oz. to the square yd. Cut fiber glass cloth squares about a half inch
larger than the template perimeter. Prepare no fewer than
five "layers", for each template shape. Each layer should be cut from identical weight
of fiber glass cloth. Set squares aside, taking care not to unravel thread.
finishing "epoxy" resin will enable the "sandwich" we are going to
construct, to cure evenly, and slowly. You can use slow cure epoxy, but it does not have as fine a viscosity as
finishing resin. In either case, you will dilute the "mixed" epoxy with alcohol
so as to increase flow characteristics. This reduces the viscosity of the epoxy allowing
it to "evenly flow" into the fiber glass cloth weave. The ratio can exceed 50 to
60 % of epoxy, by volume.
