Ok for most folks this won't be any big deal, but it's a NONmolded PVC skinned board with a double in a single concave. The exterior lamination is being done on the bottom and I built this without a rocker bed or table. The key is to shape the bottom of the board after hotwiring the rocker. Then, the bottom skin is bagged under a fairly low vaccuum. When the bottom skin is attached - lets say to a single or a single to double, the top skin when laminated will create a structure stiff enough that you don't need a table.
