Hi Neil,
No final figure, but the uprights and the 8ft spars are from industrial shelf/racking units and were kindly donated by my employer. As I said we have to sort some boards and steps, for which I am budgeting a maximum £200.
I had a couple of options for the boards one of which was 18mm ply and 3"x2" joists and the other was 38mm chipboard. Front to back would be about 3' and for storage and transport the width would be 4', so I would need 6 off.
Any one have opinions on the relative strengths?
