Repeat steps 15-17 to assemble the opposite leg.
Step 18.
Lift one side of the tower up and place one of the legs into place.
Step 19.
Fasten the legs using four 4” threaded rods.
Insert the threaded rods through the predrilled holes then thread
them into the t-nuts.
Fasten the outside using washers and acorn nuts.
Step 20.
Use a 4” lag in the predrilled hole on the end of the 2x6 leg to finish
