I'm currently working on a couple of columns to go with my cemetary fence. I'll have about fifty feet of fence with two columns at the entrance. Inside one of the columns, I've built a pneumatic popup.
I thought I should snap a few photos in process, just in case anyone is interested in the workings. So far, I've just been testing the mechanics and getting the structures built. I have no idea what I'll end up with on the top of the columns. Possibly gargoyles if I can find two good ones that match. I like the one I have but I can't find a match. All the ones I find that are similar have canvas wings.
On the front of each column is a small light (not drawn on my original sketch). I wired an outlet inside each column. I have controller for the popup, but I think I'm going to leave it without a controller. I like the idea of remotely controlling the outlet rather than using a PIR.
The images shown are a bit messy...I was testing the movement. My first attempts didn't go so well. I had the flow set so fast, the cylinder blew a hole in the top of my skull. I don't want anyone having a heart attack...so I've opted for a slow, creepy speed.
The columns are approximately four feet tall. The bottom half of each column will remain hollow so I can cover a set of home speakers or a small crate amp in each. That area will be covered with carved foam to look like brick or stonework. I'm still pondering whether to leave a flat oval area uncarved...for a plaque on each column.
I'll coat each column with drylok and then paint them a dreary gray (w/white trim) to match the house.
