A circular wooden former is made, 4ft diameter. This allows a man
to dig inside. The brick layer puts his bricks around the top of
the former. The 'digger' undercuts the former. The former with
bricks sinks, more bricks are added, more undercutting and so on.

Fascinating. Which explains the marvellous dry
brickwork in FiL's well.

It isn't a real well, it is a 'Herefordshire Soak'.
About 20ft deep, no water source at the bottom, but
brickwork arranged in an angled herringbone fashion,
so that water can percolate in sideways. Ideal for
use on (impermeable) clay soils, where the water
actually lies between clay layers.

I always wondered how they did such accurate brickwork.

Thanks.
