Voussoir Centring

Support arch blocks while the arch is built

The temporary form an arch is built on: a solid semicircular rib with foot pads, sized so nine Voussoir Wedges sit on it. Stand it up, lay the wedges from both ends, set the keystone, then slide the centring out sideways and watch the arch carry itself.
