My board is almost done just need to spray clear coat on it.
waiting for pads and fins ..slow mail
As for the concave in your board , I used my rocker table to do both at once.
if you look back at my pictures of the vacuum process you can see my rocker table with the bolts every 6 inches for adjustment.
the ones at center i used for concave. there is a shaped wedge under the table cross wise that gave me my concave.
Hope it helps.
As for the vacuum process from west system, does not matter what epoxy you use the theroy is the same. The bagging materials you can use heavy plastic used for construction. for peel ply use polyester fabric from fabric supply. (make sure pure polyester) breather fabric use cushion stuffing comes in various thickness's
By the way were you at Ikarus camp in January by any chance ?
