I actually bought two identical ladders today, then dismantled one of them and used the treads and a few other bits to make this one.
I cut about 16mm off each of the donor treads and fitted them halfway between the existing ones. I also installed a second brace on the back and then drilled some 53mm holes in the top for 2" eyepieces.
I will also be installing a taller folding handrail once I work out how to lock it securely in the up position....
