This is my pneumatic version of a Skelly Coffin Groundbreaker. It's a work in progress, static portion is complete, still have to do the controls and audio.
Top of the coffin is 42", the top of the skelly's head is at 3 feet. He's mounted to a 4-bar linkage that when triggered, he jumps out and up to 6 feet to the top of his head. He only comes forward enough to clear the coffin so you can literally be standing about a foot in front of the coffin and he ends up right in your face. I'll post a video when he's finished, can't wait to unleash this one.
Spent a good part of the day on the controls, didn't think I would have it working this fast but here it is in action. Not sure if I'm staying with this audio but it'll do for now.
THAT is FREAKIN' AWESOME! Looks great and is going to be a great scare! Why can't Spirit sell still like this? I would totally buy it and put it up front in my cemetery.
Wish I didn't sell it.....I like the height your getting from the ground, I had to elevate mine up about 3 feet so when it activated it went up over people....It wasn't very impressive at ground height......Great job!....ZR
Wow, wasn't expecting it to completely pop out! Is it triggered by a PIR near it? A scare cam on Halloween would make for some fun footage. Awesome work!

I have to warn you though, there's no instructions on how to use the program and it's not user friendly at all. I just play around with it until I get a setup that fits my application. I also used that program to design the linkage for the Scarecrow I did last year.
Hey thanks for compliments. This was totally my own design so there's no tutorial out there. There are so many elements of this prop where the dimensions are super critical, I mean down to a 16th of an inch. For me to write up detailed plans would require a serious chunk of my time and even then, if it's built to specs there's a pretty good chance that something will be off enough to cause problems. For those reasons it's doubtful that I'll do a tutorial.
No worries. Looks like I’ll just go through the trial and error myself and hopefully have it up by next year. I already have tons of stuff to make for this year that I don’t have time for. Definitely one of, if not the best, props I’ve ever seen.
