drawn out per Bill Wurts, AKA stoneburner's, plans on fresh cut 1lb foam from scrap block
insert slot cut out
I'm curious, why did you insert the channel instead of simply shaping the channel into the original foam blank?
Send me your dinged, damaged, and yellowed.
great question. In mass production the simple solution would be to glass, cnc or replicate cut and glass cut out section.
look from back. reinforcement bottom and top
wood on top and bottom in bag after final profile shape
Light soft eps, "thick" wood skins, no stringer, no rocker table on photo, how do you keep rocker under pressure ?
Great question. Vac bagged flat deck first, Shaped the 5" or so of nose with 60 seconds of planer use and a few minutes of hand sanding to match rail profile per bill wurts. The next one that is non wood will vac bagged cf or other exotic glass will probably do bottom first and put in simple jig to get the nose flip, then shape deck and vac bag top. vac bagged first floppy eps surfboard blank in 1985. never have had a problem changing or keeping intented rocker under vacuum .
