Im new to shaping and was thinking of cutting a cheap eps blank by rolling a hotwire cutter jig on wheels along two temporary stands either side of the block with rocker profiles mounted to each. Is this an old idea? Right now im just in the research phase for a project in the fall. Not sure if ill make a longboard or a sailboard. Might be over my head but thats thats half the fun.
Patagonia’s Point Blanks does something very similar. Don’t see any reason why it shouldn’t work.
