it not really that big of a deal.....assuming this is not a production job and you are not trying to bag it in on shot.
one of many ways would go like this:
a rocker table will help.
otherwise a flat table with a couple of bricks to prop up the ends and some clamps to hold down the center section.
some smooth plastic sheet to act as a 'release cloth' between your board and the table and the clamps.
cut a piece of glass for the top with 1" of overlap on to the bottom.
cut darts in the corners where necessary
use masking tape to hold glass in place on bottom of board
once all is smooth, laminate with resin of choice ( epoxy or polyE)
it will be fine if you impregnate glass down to the bottom edge of board and not the bottom.
clamp board to rocker table
once "green", remove clamp, trim back all the 'nasties' with a razor then clamp until full cure.
once the top is cured, clean up lap area again.
repeat above for bottom lam.
tape off a smooth line to cut lap to once green (if you want)
cut bottom cloth to overlap top lam by approx 1 inch ( anything over 1/2" is fine)
clamp in table to reset rocker( dont forget plastic sheet this time)
let it cure (2 days) before unclamping, trim, and sand.
check some left over resin in the mixing pot to see if its suitable for sanding ( or even cured)
use good laminating procedures
prepare/plan for all the steps in advance of doing any of them.
remove grease/dirt /contaminants etc with isopropyl alcohol
blow off all dust with clean air ( no oil)
weigh parts before mixing (glass/resin/ hardener)
with epoxy you should be able to lam with equal parts of resin and glass
(for epoxy ,if you are wrong you can add more later)
(for poly mix more than you need)
a small test piece is always a good place to start to iron out all the details
