Here's my first tutorial, hope it helps.
How I created my graveyard fence:
The horizontal cross bars are made from pine 1x2x8 boards. The vertical bars are created from 1/4" electrical conduit (looks like PVC pipe, but they are grey in color). I cut the 1/4" conduit into 3' sections, which left the last remaining section with the flaired end longer (about 4' long).
Here's a couple of pics of when I was cutting the vertical bars:
Here you just make out the flaired end on the longer pieces that are upright leaning against my house:
Next I used a hole saw bit on my drill to make holes every six inches on the cross bars, and then slid the vertical bars through the holes:
Once it was all even I screwed the bars into the cross bar. I first started out drilling the hole first and then screwing it together. However, I quickly found out that I could just dispense with the pilot hole and screw it straight through. Only a couple of minor cracks. Screws I used:
Here's the fences before painting (notice the longer flaired bars on the ends, and all bars are even at ground level):
I used cheap spray paint (about $1 per can) that I got from Lowe's (Helpful suggestion - Get a good spray can grip like this one. It will save your fingers a lot of cramping. Trust me.)
Here's the Pièce de résistance; the finials really make the whole thing come together. This is a link to Steel Supply, L.P. where I ordered the finials: Steel Supply, L.P.
I used wooded dowels about 6" long with the end wrapped in duct tape to hold the finials, and to make a tight fit into the vertical bars (this way I can remove them later if I wish). I ended up putting finials on my tall end bars, but I thought about putting the tops of tiki torches on 'em; or maybe mount skulls, etc. Just ran out of time this year.
Here's the fences in place with nothing on the top of the end bars:
I cut rebar into 18" stakes that I drove into the ground leaving about 3-4 inches above the ground and just set the fences onto the rebar. I only did the end posts and it was pretty solid. You could add more in the middle if you wanted, but keep in mind that the rebar going up inside the vertical end posts will hit the screws if they stick out too high above the ground.
