so, inbetween dodging rain and resting my shoulders, the ramps are coming along nicely-ish.
obviously, as a first-go, there's a couple of slight miscalculations (who'd have thought that a cutting disc would cut so widely?), but i'm now in a quandary as to how to brace the support portion of the ramp or even if need be?
dimensions: 103cm length, 25cm lift, 25cm rungs using 30mm X 30mm X 3mm angle steel.
the diagonal and horizontal frames sit directly upon the vertical supports.
i'm tempted to go with the red example. i may be adding a vertical support to the ramp portion, depending on what metal i've got left over.
of course, i don't want to make them too heavy and i've already revised the layout for the number of rungs.
(btw, the image attachment thing isn't working)
