There is a 2"x2" shelf on the bottom edge upon which it should be possible to place some bricks for a load to stabilize the platform. | |||
In the parts list, the 1.5" screws are meant for the braces and the 2" screws are meant to attach the base plate components. | |||
The dish is to be attached to a 2" conduit which should be attached to the 2x4 upright. It will require 4 holes drilled into the 2x4 to accommodate 2 u-bolts. | |||
Apply wood glue liberally to all wood to wood connections. | |||
