Step 1
Contact your local building section to discover out the prerequisite for footing depth and to determine if a building permit is needed . Rock column that are more than 4 feet gamey may require drawings that are stamped by a professional railroad engineer . Prepare a sketch of the sway pillar to guess the identification number and size of rocks required .
Step 2
Dig an area for leg it with the shovel . Fill the bottom 6 column inch of the hole with clear aggregate . If you want to have a squared - off concrete groundwork that is above the ground and visible , shape the scrap pieces of wood into a straightforward shape that is 6 inches larger than the breadth of the pillar . Ensure that the four pieces of wood are nailed together at 90 - degree angles , and attach cross bracing with other flake forest for support . set the squarely - shaped Ellen Price Wood in the right position with the mark bracing on the upper side so that it form the extinct edge of the concrete groundwork .
Step 3
Step 4
Mix concrete in the pail or tub with the concrete mixer . Pour concrete into the maw and the wooden concrete form so that the concrete will be 4 to 6 inches above the solid ground . Level off and smooth the concrete with a wire thicket , trowel or emery paper . Allow concrete to pose and dry out at least 24 hours before laying out the rocks .
Step 5
strike out off the desired locating of the rock’n’roll column on the concrete radix with a pencil . Choose four flat man of Edward Durell Stone for the cornerstone . With a mallet and chisel , smoothen off the bottom of the rock so that it will lie flat on the concrete base . blend concrete in a vat or pailful with the concrete mixer and implement a 1 - inch level to the concrete base . Set fundament in the right berth . Fill in the blank between the cornerstones with more rocks and concrete .
Step 6
Step 7
uphold to localise the rocks in the concrete , laying out the cornerstone first . As you approach the maximal acme of the column , use the hammer and chisel to mould and size the rocks so that the top of the pillar will be matt . Finish off the tower by implement a stratum of concrete to the top of the pillar and then arrange the coping Harlan F. Stone squarely on top .
