i will be building a 4.8 thruster fin board this weekend and will post pics at that time.
9.5.09 this is what the 2009 4.8 cores look like , wide diamond tail with wide point set back past center.
9.5.09 Friday night i cut in the Futures fin boxes and set them in epoxy and scimmed the core with fast&final to fill voids in the foam, side boxes were set at 11″at tail with .375 toe in and tail fin set at 3″ at tail. In the a/m i will router the rails and sand with paper to desired shape.
9.6.09
This a/m i spent one hour shaping the rails with a 3/4 , 1/2 and 3/8 router bit to get the shape i want, and now its ready to get 10oz. of Sglass on bottom with Greenroom epoxy.
