All right, you may laugh. Your hips and knees will go one day....
At least I know that on Monday morning when climbing on to the boards to fit the joists, I will not get a gasp-inducing stab in a hip or knee when crossing from ladder to trestle board. And - best of all - I'll be able to climb down in comfort.
@Onoff: any way of motorising this? I have a spare lawnmower engine somewhere.
