thanks marc for your reaction.
phil the bow's of the roof are made of oakwood as the whole frame is and the bow pieces are made in 2 parts with special connections screwed together to form the bow. this way it's strong and light at the same time.
on the roof part are only 2 pieces of angle iron to support the roof from bending down when you stand on the roof, but the rest is all oakwood.
I can take pictures if neaded no problem.
cheers jaap
