Posable 6' - 10' spider (Finished!)
Hi everyone! I was building a giant spider this year and thought I'd take pics along the way and share them. This is a 6' spider based on the shape of the wiper spider prop by PR0CRASTINAT0R on youtube (4' body and 2' extra length with the front legs) but the price between the 6' and the 10' shouldn't be that much different as I think my 6' spider only used about a half sheet of 2" foam. I used alot of scrap foam so I'm not exactly sure how much foam it used. I'm going to break it into 2 parts: building and finishing. I think the building part will be the toughest to get through so I'll be posting that first and post the finishing later this week. Many people will have their own way of painting/finishing as well, but my method will (most likely) be sanding, monster mud, sanding again, then painting along with any embellishments I think of on the way.
Here's a great website at Zombietronix that has a spider proportion calculator if you want to change things up a little:

Fist off - supplies:
24 - 3/4" pvc 45's ($12)
8 - 3/4" pvc tee's ($4)
2 - 10' lengths of 3/4 pvc ($4) 3 lengths if you want a larger spider
16 - steel brackets ($5)
1 - 2" XPS foam board ($20)
scrap 1/2" or 1" XPS foam
scrap 3/4" plywood
a bread knife and utility knife worked great for cutting down the foam
I used the 3/4" plywood as the backbone of the spider and the anchor for the steel brackets that hold the legs on. The orange 4' level and the 1' ruler are in the pic for scale. I took alot of weight out of the plywood by cutting out some excess wood from the back part.
next is applying 2 layers of 2" of XPS foam to the entire top of the spider and attaching the pvc tee's with the steel brackets to the bottom of the head part. The brackets are screwed tightly only around the outside of the brackets closest to the edge of the spider while the screws toward the inside of the spider are screwed just enough to keep the pvc tee's snug. This will alow the legs to move freely for posing and can be screwed down tightly later to keep the pose. If they're not snug when screwed all the way down, wrap some duct tape around the tee's till they become snug.
Cut a small piece of 3/4" pvc and glue it into the tee's to add some length so the 1st 45 degree elbow is at least past the edge of the spider. This will be the only pvc fitting that will be glued.
The next two parts are just building up the spider's body. First is building up the body around the legs. I used 2 sheets of 1/2" foam board, cutting out holes to fit over the tee's, then cutting around the interior row of screws so they can be adjusted whenever needed and keeping a section in the middle to support the black cloth that will be used to cover up the holes after completion. After the glue dries, carefully cut out an area for the pve tee to fit into so the legs will rest close to the plywood.
Building up the back part of the body is pretty much the same. I used a piece of 2" foam for the bottom of the back and 2 more pieces of 2" foam for the top of the back (bringing it to 10" total, 2" on the bottom and 8" on the top) After cutting away the foam to get the right shape, cut the pvc to the desired length for the legs making sure not to glue them together. All the legs will be posable up/down and front/back. After pushing them tightly together some duct tape or screws will hold them in position for the season and allow you to break down easily for storage.
I'll be adding to the post while I get to the finishing part but basiclly I'll be sanding it, covering it in monster mud and painting it black then adding some slim white fangs, red eyes to the head and a red hourglass to the back to make it a black widow.
Hope you enjoyed it!
The second half of the build is now ready! Go down a couple of posts to see the pics
