This is a Scissor Prop I built for 2012 . Hope you like it.

Very, very cool! I sooo wish I could wrap my head around pneumatics, they really add so much to a haunt. This guy is a great prop, nice job!

Fantastic job. Is the arm raising motion an extension of the scissor arm or do you have another cylinder raising them?
Thanks for posting.

Very cool and thanks for posting. This is exactly one of the items on my to-do for this year, but as a zombie and with less reach. I like how you anchored the cloth for the feet to the chair cause I was struggling with what to do about the lower body.

The arm motion is made all at the same time with the scissor. One cylinder in the prop.

The arms raise up as the scissor extends out. One cylinder in this prop,

Sorry for repeating my self. I keep replying to the wrong Post. The arms raise up as the cylinder extends out. One cylinder. Pretty cool prop for just one cylinder.

Before changing out the air cylinder try using a flow control on the return it will let you adjust the flow of the air going out of the valve on the return and slow it down. Maybe you're using one but from the looks of the video I'm guess you're not...if not it will fix your problem

omg the tots are going to krap their costumes!

perfect execution!

the return speed is ok ... are you thinking the fast return will cause the prop to self destruct or other wise damage the cylinder?

madmax's solution would do the job!

amk

 

[Scatterbrains]

do you have a pic of the arm movement without the costume on it.?

 

[Widowmakerproduction]

I think I do in another video on You tube under "widowmakerproduction" titled "lost scissor hinge video" something like that around Feb. of 2012.

Thanks, that's what I needed to see.

Now I can tinker with one of my scissor props. The motion looks similar to a body slinger I want to build and hadn't thought of using it on a scissor

Awesome prop! The quick return is actually more scary as far as I can see, but I can understand if it's tough on the mechanism. Anyway, the effect's great - I like the eyes, too. Glowing eyes can look cheesy, but these work well with the prop.

Though I have to say, before I watched the video I was expecting zombie Elvis .

 

[crazy xmas]

Wow totally cool!

 

[S.O.S.]

Fantastic. Really well done.

 

[kprimm]

Super cool prop, you certainly are very good at what you do. Like the movement of this guy alot. That will scare the bee jeebers out of people.

I've aways wanted to understand scissor props and damned if I could ever wrap my head around it. Until now. Thank you so much Greg!

Here's the video WindowMaker was referencing about how the arms move. He starts explaining the scissor prop itself at Time Stamp 2:54 and then at 9:35 he explains the arm movement:

Thanks Terra,
I am going to build "The Castle Grey Skull " well at least the face out of foam . I think out of foam. Google it. It was a kids toy from the 80's. I also thought of using a foam skeletal structure and covering it with wire window screen and Monster Mud. Oh ya did I mention that it was going to be 8 1/2 feet wide and 14 feet tall. It will also be made in five different sections. Any thoughts you would have would be greatly appreciated.

use a quick-exhaust valve on the retraction port, flow control needle valve on the extension port. That way, you still get the speed outward, but reduces slamming on reset...

Nice post! Maybe move to the TUT section?
