Storm Damage Questions

Where the fence use to be

The high winds and heavy rain from the Pacific storm over the weekend knocked down two Redwood lattice top fence panels in our backyard.

A new 6×8 section is about $US 90. The only damaged pieces were the header and sides. They have a groove routed in them. Nobody sells them. Can’t I just buy a router and some Redwood 2x4s and make them myself?

Also, the one 4×4 support post that broke at the base was just buried in the dirt. (01/08/2008: Actually, the post was in a concrete, I hadn’t dug deep enough) I have this concrete support that holds up our house. Can I just bury that and use that to support the post?
