Mike :wave I was considering the same thing,making my own storage shelves. I took a look at a trillium
that had fiberglass trough type shelves that would have been made in a mold from the factory. They were attached by means of pop rivets through the walls.To time consuming I think
Also seen a Boler
with aluminium shelves made from airplane grade aluminium with cutouts for taking stuff in and out. I talked to the fellow who made them and he said he attached them by means of brackets and pop rivets. He still has the templates but was not to interested in making up any more of them.
I would like to see more of the trillium
pictures that someone posted on here with more detail. I like the idea of not using pop rivets.
