So, last year a neighbor was throwing out a wheelchair - nothing wrong with it. I grabbed it up knowing I wanted to use it for a scare I could roam the neighborhood with.

I took off the back (6 screws) and replaced it with a wooden platform for the scissor jack. I used steel L frame on base and two pieces bolted together for holding the scissor jack. U-bolts around the chairs arms hold the bottom and top (top U-bolts not in this picture)



After getting it to work, I redesigned the foot connector ...



Here it is when sprung...



Front view when sprung...noticed I did disconnect the hips from the spine...was worried about it being too heavy.



This could easily be transformed into a pneumatic prop, removing the pvc foot trigger and building a 'floor' for adding a tank for air (I thought a tank could be disguised as an oxygen tank for poor old skelly) and a cylinder to spring it.

Hopefully, I'll dress up the skeleton as Aunt Libby, where she will look sickly but normal, and then spring it to show bones underneath. If I do, I'll update this thread.

FYI - 3/4 inch pvc cross connectors slide on to bottom rails with no issues...I used 1/2 inch pvc with another 3/4 cross connector that slides free on the 1/2" pvc, giving it the way to spring the scissor jack by stepping down on it.

Manual or pneumatic, that'll look great. Makes me want to start playing with scissor props.

When you dress her, don't forget to put her in a two piece :D

Thanks Nebulosity and Russell.

Amazing that I looked all over trying to find a set up before building and could not find anything but one company that was selling something like this for $5000+, yet here Russell did it back in 2008, and last night I went to Howl-o-Scream at Busch Gardens, and the last thing we saw as we were leaving was a guy (employee of BG) running around with a monster/granny in a wheel chair. His chair used a 2-bar lift to pop the prop up about 4 feet. Really made my night, got a quick look at the mechanism.

We hadn't gone to Howl-O-Scream for about 10 years so I don't know when they started using this, but it's exactly the perfect place to be able to run around and scare the [email protected] out of folks (I would have left the employee in normal employee clothes ... instead he was dressed like one of the scary people so you knew something was up)

still need to make the shawl open up to show the ribs, spine, and arms.

That's cool. We sometimes go camping for Halloween where there's 300 sites full of campers and everyone decorates. That prop would be killer to walk around with!

Changed out wheelchair prop for remote jumper scare. Just changed manual process to air cylinder pulling down to launch Grandma.
