Moulding step treads for the Staircase.

After many months of working through ideas of how to box up the spiral staircase, Francis had decided to make moulds and cast the treads. The underneath of the staircase will have to be constructed out of Hebel at a later stage. We can cast nine treads at once in the mould. We had a volunteer to help cast the second set of treads and four more Crenels.
