Well, certainly some things to think about. Given the amount of material needed, in terms of linear feet, I might actually be kidding myself in terms of weight saved.
Dance is a heavy old lady and I've been putting her on a diet as much as I can. While 60-80 lbs is isn't much in the grand scheme, its still 60-80 lbs of water
While wood would the easiest, I find that metal will give me more space, with similar or slightly less weight per foot depending on section. I am planning on building all the furniture framed in aluminum
, and I do have the steel
to do the floors.
My frames are 33 inches apart so the fore and aft frames for the floor have to span that much. I could put a vertical in at mid span, welded to the skin but I'd prefer not to. I currently weigh some 300lbs and figure that 1 or 1.5 inch angle will do as I use 3/4 ply floor plates. Very stiff, no flex at all.
I'll ponder the question some more over the next few weeks. For now the old wood frames have been reinforced with angle clips and are holding. But they will eventually have to go as the floors are currently made of bits and pieces cut to fit around the old furniture and as mentioned are rotting.
Thanks for the input. S'what I love about this place. Instant knowledge.
