About 35$ for Baltic birch. 8 oz. S2 glass about 8$ per yard. 660 KSI carbon about 35$ a yard. This is all you need to do a basic lamination using weight to smash it down. Better results can be had with vacuum bagging but, would require more investment in materials. A fine tooth metal blade will cut the finished product just fine. CONTROL THE DUST!! Do not allow epoxy on skin and ventilate well. Be aware that there are some people that have amine allergies. Laminating is not that difficult. The are many videos on your tube.
A 3x4 piece on mcmaster (with their high prices) of 1/16" g10/fr4 is only $60. We've been using it for years, that gets you a bellypan and plenty of spare material.
