Re: Strip: Building Bjorn Thomasson's Frej *PIC*

Shaping the sacrificial foam to the deck underside shape is easier if you 'hollow out' the middle of the foam - the only contact that matters is at the edges. Don't make the remaining foam too thin, though, as it does need to remain flat.

I used the same method to make a recess for the back of the coaming. Bjorn suggests recessing the coaming all around, but I didn't want to lose 'foot clearance' at the front of the coaming, so decided to drop just the aft part. This also helped to straighten out the plane of the coaming. ('S' shaped coamings don't hold spray decks as securely...).

The foam forms are glassed over from the underside. I usually coat the form with thickened tinted epoxy as a first layer, when laying up the glass laminations - it gives some 'insurance' against sanding into the glass later.

Next step is to cut down through the deck to expose the glassed recess.

There is exposed wood once the deck has been shaped to meet the recess, so I added another layer of 4oz (the cloth really acts as a thickness control here) and epoxy.
