very kool prop i would like to build a few for my haunted house what type and size pneumatic cylinder did you use

[houseofbaddreams]

In the case of this prop I used a converted door closer, but a 3/4 " or 1" cylinder with a throw of 10" to 12" would work. of course it depends on how high you would like the four bar to lift and the weight of materials used. when working with the door closer I went as light weight as posble the prop and armature weigh less than 15 lb. if I had used a real cylinder I could have used heavy materials like steel squre tube. Also be sure you watch all my vids on this prop for what not to do as wel

@houseofbaddreams how much worth of pvc was that do you remember?

[houseofbaddreams]

@mortarlover123 It's been awhile but i beleave it was just over 2- 10 foot pecies of 3/4 and less than 10 foot of 1/2 but i recomend going to 1-1/4 inch and 1inch if you havent already watch all the videos on this and you will see why i say that.

Do you have it attached to a motor?

If so what kind.

[houseofbaddreams]

[TrueMetalHead91]

Sweet! Really neat.

ok so i know how to do everything on this except for the air part i know you have to get a cylinder but do you hook that up to a switch or what? or in better words what triggers the air to get to the cylinder?

[me80233]

how would you conver the door stopper into what it is in the prop?

[mortarlover123]

@houseofbaddreams yeah i saw that it cracked, but idk i was thinking about going with Metal stock, but its so damn expensive haha
