Create Galvanized Conduit Sections
Create the other half of the fence sections using galvanized conduit. Instead of creating a routered groove in the framework like the previous sections, figure out how many evenly spaced conduits you want top to bottom. Using a drill with an appropriately-sized spade bit, drill holes on the two side 2x4s to hold the conduit in place when the framework is together. Then simply screw together the framework, making sure to slide the conduit into place before the second side is installed.
