It is better to laminate from downwards-up
Reduces risk for dry-spots - the resin cannot just flow in-accordance to gravity
Depends on the scale of the part
Perforate your core with 1/8” holes spaced around an inch aparthelps the resin flow-through adequately through both-sides
can use school’s CNC machine to program and cut-holes
Always perform a vacuum-drop test before starting infusions
Use breather if-possible to prevent the bag from being punctured
Always add lots of pleats to your bag so that every-crevice is covered
Instead of wrapping the chromate tape around
Two calculations Calculations for resin:

...
square inches per ply * (1/1296) * type of material you are using * # of plies used
general rule is to give core a buffer of 10%, and for all-else a buffer of 10%
good to perform a gel-test with a small amount of resin to see how fast the gel runs-through - record initial temperature, amount of time which has passed and amount of catalyst-used
Male versus Female Mold:
Male molds are better for when you want the out-side of your part to look nice, for example for the aero you want the outside of the car ________Record the temperature before-and-after bondingto be the “A” side to decrease drag so you use a female-mold
