That’s a great idea, Les! A truss would provide strength/stiffness to the ramp.
But there is a second element to the ramp that I have not mentioned yet:
Due to the high floor of the bus, I plan to build a bi-fold ramp. I have a “slab” of
aluminum, 8 feet x 10 feet 5 inches, quite stiff -- maybe 1/8 thick with an inch thick
ledge around the sides. (I have no idea what it was, but it looks very air cargo.)
The idea is to cut it in half and get a ramp 5’ 2 ½” wide and 16 feet long. See top drawing.
I’m also toying with the idea of making a beavertail in the floor -- see bottom
drawing. Would require taking a slice out of the frame rails, but with these
cut-off blades, that seems perfectly doable.
Yes, I have no shortage of ideas and ambitions!
Right now, I’ll settle for getting off the fence and cutting the top loose so I can
start jacking when the wind dies down. Sometimes you have to do SOMETHING,
even if it is wrong. Oh, somebody thought of that earlier:
"You may never know what results come from your action.
But if you do nothing, there will be no result."
