Pillar to PostUpdated: December 30th, 2018Created: 21/07/17
The pillars will be in two pieces, a) the base of some 20" (60cm) square rising to 8" (20cm) square and b) a preformed truncated pyramid of base 6" (150mm) sq; the top 4" (100mm) sq. with 100mm of copper rod protruding some 50mm.
Example: Pillar 1 Base
The mix is 1 bag sand, 1 shovel of OPC, 1 shovel of pea gravel, 1/2 shovel of hydrated lime.
All things considered with no levelling it seems reasonable, one of the small top, truncated pyramids was also fashioned.
Truncated Pyramid Top
Top 100mm square :: Height 100m :: Base 150mm square

Given beam widths of 100mm the corner pins are:
length 6500-(2x50)mm or 6400mm | width 4800-(2x50) or 4700mm
diagonal is 7940.4mm (7940)
(6400 x 2350) diagonal is 5685.9mm (5686)
(3200 x 2350) diagonal is 3970.2mm. (3970)
