I bought an EPS blank from a place called ProFoam in San Marcos http://www.fusreps.com/ . He calls his blanks FUSR EPS I believe the foam is 2.5 #. The beads are very small, well fused and don’t seem to tear out real easy while shaping. The foam was different than previous 2# foam that I have used. This foam seemed to be more dense and had a “crispness” to it as if it had been fused with epoxy. As far as shaping goes, I liked the foam. Not as “crisp” and nice to shape as a poly blank but overall not bad.
The blanks come in a rectangle shape with the basswood stringer glued in and the rocker cut in. They did seem to go a little overboard on the amount of glue that they used on the stringer. There seems to be a decent selection of sizes and rockers. The blank I bought was tagged as a 9’1"Y. Supposed to have the same rocker and thickness flow as the old Clark 91Y. I had used a number of Clark 91Y blanks in the past and this eps blank was not quite the same, more rocker in both the nose and tail then what I was use to with the 91Y.
Overall, satisfied with the blank and will try the FUSR 10’1Y next.
