Now , the head section . You can use another 4 way somewhere up near the neck area so you can have another little piece of PVC pipe there for the appearance of shoulders , which , is whay you would drape your shirt/cape/ or whatever , over .
I can kinda sketch you out a little picture if you need me to .
PVC works fine as long as you realize that
1) you can not have a lot of weight on it .
2) use a thick enough piece ( I used 3/4 inch for this )
3 make sure you GLUE and not just use the tight fit to hold things together where the PVC meets PVC .

Oh , and I left something out .
For the side sections that hold the prop up and is the pivot area , I used a cap on each end that went to the sides of the coffin and drilled a hole thru each cap just big enough for a piece of threaded rod to go thru ( from one side all the way to the other side ) and had fender washers and a nut on each side to keep the fender washers in place and tight so that the hole thur the cap would not get wider or spread .
I know that wording sometimes sucks when your trying to picture something , so , if you need me to , I will try and post a sketched pic of what I am trying to describe .

Yeah I would love some pics or sketch if you have it? I'm definitely more of a visual person Thanks!

Thanks Scatterbrains. Thats one of the sites I was thinking about but just wasnt sure about the integrity and safety of using the PVC.

If you have any questions about it, send Propmaster an email. He's a really nice guy and loves helping out fellow haunters. I want to make one of these too to stick in the funeral carriage I'm building

K thanks Scatterbrain. I think I'm actually going to forget about the pop up for this year since its going to cost me over $100 for the cylider,solenoid and misc parts and everything. Ive already spent enough of this prop as it is.. lol As I'm sure many of you are very familar with

You can take a reindeer motor. rig it to wind string. when the string winds on the shaft the body and the lid will raise.. Once the string gets to it's limit. The motor will reverse itself, lowering every thing back in place. It doesn't give you a startle effect, but it makes for a creepy addition to your haunt. The coffin lid would need to be made of foam.

For my props I use a door closer, $8 - $10 from Home Depot or for longer throws I use a bicycle pump.
