    Default Electrified Fence for dino theme

    Electrified Fence for dino theme
    Determined to pull off the dino theme this year and working on an idea for an electric fence to cordon off areas where I will be using AtmosFear's Dino Experience projections for "live" dinosaurs. I'm trying to keep the cost down, easy construction (limited tools), materials need to fit in my car for transport, and hopefully a convincing fence look in the end. Here's my rough drawing of what I have in mind.



    Here's some of the materials:
    1) concrete 8x8x8 in. block, interior hole dimension 5x5 in., 17 lbs. each.
    2) 6 or 8ft long wood boards, 4-1/2 in. wide, to form each post's two side sections, connected by wooden spacers for structural stability and topped by a piece with a center hole drilled to hold a LED flashing cone light
    3) foamboard for the front post panel
    4) "bolts" (push-in plastic rivets with curved heads to push through the foamboard to give similar effect)
    5) clothes line (seems cheapest route) colorized gray/silver somehow for a metal look
    6) LED flashing cone lights for use as indication of energized fence (steady red light) or trouble in a section (bright rapidly red flashing light).
    7) gray paint for wood and foamboard sections.
    8) drill for making vertically spaced holes in height of side wood panels to run "wiring" through each post connecting them.
    9) signage - Warning 10,000 Volts, Warning Do Not Touch Fence! Electrified Fence throughout the Park

    Feel free to add any comments or suggestions here.

    I'm sure I can carry home in my car 6ft long wood pieces but was considering 8ft if I can. Any thoughts on which length you think would look better? Most of the kids will be 5ft or under I think. I like the idea of a towering fence but if I go with 8ft posts do you think the flashing post lights on top of the fence will be less noticeable? Do want them seen. So far I'm planning on 7 posts to the electrified fence as a minimum to "protect" the "live" dinosaur specimens--a T-rex and a pack of velociraptors.

    I set up a HalloweenForum "2019 Dino theme" album for my projects and plan to add photos as things progress. Photo of some of the project parts are in my album.

    I could go with a 8x8x16 inch concrete block for a wider post base and the resulting foam panel would be wider than the 5 inches with the half blocks and it would look more sturdy. From HomeDepot the cost would be 1.60 (8x8x8) or 1.90 (8x8x16) so not a huge cost difference. The longer length block is 31 lbs however and not sure if I want to be lugging those blocks around. If you were doing this project what way would you lean for planning the base?

    Plan to start with one test post next week and see how it goes.

    If anyone purchases the LED flashing cone lights for their projects and is having an issue with it not seeming to work, might be that the batteries are not properly installed. There are indications on the battery holder and the top of the light but not obvious as the indicators are the same color as the lamp. I took a black Sharpie to my light to make it easier to see and get set up quickly. No instructions in the box they come in. I bought my lights off an ebay seller in Chino, CA as I got a discount for ordering several at a time. Here's my video if it helps anyone.

    If you go with the 8' boards, you may wanna use the 16" blocks. 8' tall boards will catch more wind than you think.

    Great ideas, Spookie! It all sounds good on paper.
    I hope it all comes together the way you want it to.

    Just wondered----why does it need to be transportable?

    Thanks Dave. The transportable need is so I can fit the boards in the car to get them home from HD. We have 2 new sedans with liftback/passthru trunk area that I can put longer things in through but the exact length could be an issue. 6 feet shouldn't be an issue. 8 not so sure. In fact I'm thinking of using some of the folded insulation sheathing I have at home for the front of the posts. The insulation is 4' x 50' (like these) and I can cut into 6 or 8ft sections.

    Have you considered using something like 3” PVC pipes for the fence posts? You could use rebar pounded into the ground to provide support. Making the posts out of wood is going to make them quite heavy and if you make them out of foam board I think you will need to spend a serious amount of labor making them look real. PVC pipe just needs some paint.

    I've used PVC pipe before for some projects and will probably use some for the signage I will put up. Made some Monster movie poster displays two years ago with 2" and it worked really well. Thanks for the suggestion and I looked into it. I always come up against cost for a one night halloween display (needing at least 7 posts) and even with 3" pvc sewer pipe would still have the length restrictions for getting it home. HD has some 10ft 4" diameter pvc pipe (don't see 3") and that runs 15.56 a piece. Their ABS 3" comes in 10ft sections and runs even more. In the end I think using the concrete block and two pieces of wood will be less expensive. Everything will get a coat of gray paint so either way that would be a wash likely, with wood probably easier to paint.

    Using the smaller cement block, my post width would be 5" so visually I think a nicer, sturdier look for an dino park electric fence than 3" so am inclined at this point to go with the wood and cement block approach. Do really appreciate the feedback and good to get at this planning stage before materials are bought.


    While not an electric fence in this scene, in my mind I think I patterned my fence after the posts in this movie clip. Originally had considered using pvc pipe instead of clothes line but given several lengths of it for each section, opted for the clothes line instead .




    Actually a bit more like this one (from a Jurassic Park video game I think): https://www.neogaf.com/threads/juras...post-246570770

    and definitely not as tall as these: https://vignette.wikia.nocookie.net/...20111103234347

    Now of course I love this scene for humor (looks like the posts here are I-beams) but my Park electrician won't be as lucky as Dr. Grant!




    If I do need to extend my fence length, I suppose I could use a PVC pipe in between the posts and run the clothesline through eye hooks inserted in the pipe. Kind of messes the pipe up for later use but still a possibility. Likely go with 2" pvc in that situation.

    Until I build one of the post sections I won't know how exactly I'll have the fence laid out or how many posts I'll need. The electrified fence will be used to "contain" some of the lab's "live" creatures such as this one below, our T-Rex, who'll hopefully be living in our house behind these french doors that will be turned into a containment pen for it. The other area will be the velociraptors section. I don't really want the kids to be going up to the glass doors so the fence will keep them at a distance. Pardon the very quick and messy imaging layout here, I don't bother to refine anything in the planning stage. Just for visualiztion for the most part of how the layout could work but thought it would help to see what the intent will be. The T-Rex since he's suppose to be in a container will be using the Window/Hollusion projection. The raptors that will appear in the family room large picture window I think I will be using the TV/Wall projection version and the one where you are peering through the jungle foliage so they look further off in the distance in the wild. Haven't mocked up that layout yet.

    @Spookie Thanks for the clips - now I understand what you are trying to do. I think I would go with the taller boards if you can fit them in your car. You are creating a "set" and the more dramatic the better!
