Was going to start making a cematary fence for our display. Got all the materials last weekend. 3/4" PVC (Gray so i dont have to use primer and cheaper than the white) 2" PVC for the posts, and 1 x 2 wood as the slates. Drilling slates for the tubes to slide through. Cut and marked out one slate and test drilled the drop.......OOPS to me there isnt enough wood left by the holes to be durable for many years......SOOOOOOOOOO going back to return the 3/4" for 1/2" PVC......Glad that over the years I learned to test run things rather than just start cutting and find out it dont work later.
