34mm square pine stock. Edges rounded over on the router table, and then a vee-groove routed into the pine.
6mm marine ply for the spreaders, with no stiffening since the rails will be screwed to the boat.
The the ply was chamfered with a plane, and then filleted to the rails with thickened epoxy.
Closed-cell foam will finish the surface off, and provide padding for my bum, once the seat's been varnished.
