making flanges for the holding tank and toilet seat

I started with some frame work for the holding tank and the toilet seat to glue some foam triangles under, they are large fillets to laminate against. I than screwed the frames to the foam so they stay in place when laminating against it. I made also two triangles in the front to support the end panel of the mattress. We than laminated all the flanges with on layer biax. We also put some PVC tubes against  the kitchen locker and laminated them over. As final job we laminated the piece in place of the wash bowl what I did broke and I hope that the brake line will be smooth again.
