Well the material has arrived, but I stated thinking about my physical condition. At my age I have problems just lifting 20kg, never mind the 30kg of a C5.
Plus, about 10 years ago I had an operation for a hernia, don't wanna a second one.
I need at least two stands, but what good will they be stuck in one corner of the garage and the C5s in another. After chewing the mater over for a couple of days I think I've found the solution based on mark's fab effort.
When the arm is lifted the C5 is pushed back onto the stand, the axle locates in the pivoted top of the uprights, and with a little effort, bingo it's upright, I least hope it is.
With this method I can, with ease, park the C5 with two batteries in situe (sealed of course).
I've decided to use wood instead of ali, got to watch the pennies these days.
Now I just need some measurements, the long beams, and some casters.
