Step 8: Final Assembly of the Spider

Check the spider to see if any foam is blocking the "hips" attached to the body.  Cut away any foam with an Exacto knife or similar.

Insert the legs, the pins, then respray any pieces missed.

Voila!  Biggest spider in the neighborhood.
I made this for a fundraiser party we are having tomorrow night. I'm going to put some LED eyes on it also. Thanks for the instructions!
<p>your spider came out great. I decided to try and make it , however i had problems with the joints so i had to screw them. I also made a huge mistake of not wearing gloves while working with the spray foam, i ended up with a hand covered in foam(not fun, but was funny). </p>
<p>Great point about gloves - I just updated the materials list to add gloves. Spray foam is one of the most adhesive materials I have ever used. Once it touches something it sticks, and then you can only remove with acetone, which usually melts whatever the foam stuck to! I had to shave some off my arm with an exacto knife when I realized I was out of acetone :(</p>
loved this project thank you
<p>Used these plans and expanded on them a little. I think I might have made the body a little too heavy because the legs can't support it to well. Still looks cool, it's only been up a few days and I've already received many compliments and people are slowing down while driving by to take a look at it. </p>
<p>Looking to make this this weekend. Yours looks great!! </p><p>How did you get the legs hairy?</p>
<p>That is awesome! I love the front legs holding the hand (which may be why it cannot support it very well). I found with my spider the legs were just strong enough, to the extent that the spider bounced up and down if bumped.</p><p>I'm still waiting for someone to build a version rearing up :)</p>
<p>It wasn't supporting itself before I adjusted the legs. I built my to look like it was rearing up, but when I put it on the lawn it just sank. I have some supports underneath it in the front. Maybe If I make them taller it would work. I may tweak it this year or wait till next year. </p>
<p>Next year I will remove the skull and drill it for LED lights for the eyes.</p>
First one I followed step by step, like a recipe. Lots of compliments, and strangers getting their picture taken with it and laying under it. Second went bigger, and for a poisonous look. Incorporated battery operated LED lights for the 16 little eyes ??
That's awesome! I love the longer legs - I bet it really bounces around :)
<p>Using the same materials but a bit bigger so he could walk right off my roof. I did use spandex for the body to give a bit of a shimmer. The legs were done using the spray on foam insulation and strips of burlap. I have to give credit to others on line for the extra ideas.</p>
Wow! That's HUGE. And I thought I had a problem finding room to store the legs :)<br><br>Great job.
<p>I kept the joints unglued and use a small pilot screw in the fittings to hold the pipes in the joint. This way i could dissassemble and store in my basement.</p>
<p>Looks great! We have a one story house and I plan to do this for ours. Any tips on figuring out the measurements/joint angles? </p>
Would you make me one if I paid you for it?
My son and I just finished our giant spider. I added some eyes and LED lights to light them at night. Just on the top back of the spider you can see the solar panel for the lights. We spray painted the body of the spider bright red first to fill in all the cracks and then sprayed the the body black. Nice multicolor effect. We spent 2 days and about 40 dollars in materials to build it. As always, wonderful ideas and instructions to be found here.
<p>Cool! This could become a photo op for trick-or-treaters. They could lie down and become part of the scene</p>
This is a better close up of the eyes to show more details. All of the eyes started out point forward, but through the process of taping the wires down and the the shifting of the spray foam some changed their orientation. All and all it seems to work.
Here is a closeup of the eyes. They had small holes in the tops of each eye that I wanted to close up so I just used the spray foam on each which created a bubble that just added to the organic look of the face. I used an empty windshield washer plastic bottle cut up to form the pincers and a scrap piece cut into small teeth with 4 LED lights behind them. This turned out so good that I want to make at least one more spider to put on the roof of the garage.
That is way cool! Can you post a close up of the face (spider - not son :))
<p>Fantastic tutorial! Made this over the course of a week with for this year's decorations with stuff we pretty much had laying around the house! Sadly I didn't have the supplies to make teeth or a crazy body, but I like him! Thank you for the instructions! :) </p>
<p>great use of web. Probably very cool to walk under on Halloween night</p>
<p>Thank You for the IDEA. I used a 2 liter soda bottle and fastened the legs to it.</p>
Awesome! I love it. It's almost scarier with a small body - kind of like a giant daddy long-legs.
Just finished building a version of the spider. This was really easy and fun.
The skull one definitely wins the creepy contest. I think I might have to make one of these and hang it from my ceiling. <br />And this is a great Instructable. Plenty of detail but kept relatively simple. Good work.
Just letting you people know. to save money for the body I just taped two shoe boxes together.
Didn't buy glue or primer, bought a few extra joints JIC, 37 dollars.
Love it! We are on our way to the local HD to pick up all the stuff. Love your tomb stones too. Go Ducks!
How much does it cost for all of the supplies total. The thing is that I really want to try this but i don't have a large amount to spend.
the skull is over the top cool !
AWESOME! I should make one of these! I will make it move though!
I would be scared out of my wits if that thing would be real!
Great Spider - looks way easier than the paper mache-over-ballons version I did one year. One 'simplification' option on the legs would be to eliminate 8 of the pvc connectors (and the 8 short stubby pipes), by having 45 degree connectors come off the spine instead of the 90 degree ones. I haven't done Holloween decorations in years, but this 'ible may inspire me to get back into the spirit!
I don't think removing the 90-degree elbows and stubby bits will work - the legs would all be perpendicular to the body, and they need to be flared.
Here's a sketch...
But I now realize that my bad suggestion would not allow rotating the legs. They would have to stick straight out.
Are your tombstones football teams? If you had one that said &quot;Florida Gators&quot; that would pretty much make my day :) I'll die happy when USF beats them.<br><br>And more on topic: I love your spider. Will definitely have to try it once I don't live in an apartment any more.
We're huge Oregon Ducks fans - all the tombstones are the Pac-10 teams and notable other recent wins - Sooners and Michigan
Love it! I saw clips from their first game of the season where the score was something ridiculous and they made the poor guy-in-a-duck-suit do an insane amount of push ups. You back a good team. I'm anti Michigan also, so that's good enough for me :)
Beating Michigan at our home in 2003 when they were #3 was awesome, spanking them in 2007 in Michigan was even better. Nothing like running a Statue-of-Liberty play *and* a FAKE Statue-of-Liberty play against them in the same game :D
Hehe... Great Stuff is not great stuff. Good luck getting it off of anything.
I respectfully disagree: It's great at sticking to everything, including clothes, skin, hair, children, pets... :-)
this is soooooo cool awsome yur awsome thanks<br>
My wife is a spider nut and saw this . . . guess what I'm on the hook for making next Halloween? :)<br><br>There have been a few similar projects like this in the past, but this is my favorite by far. Well constructed and the organic look from the spray foam really sets it apart. Love it!
Built this today. Added golf balls for eyeballs. Used the foam to create pincers. Double check the total amount of PVC pipe needed to save extra trips to the hardware store.<br><br>60 ft PVC tube needed<br>Step 24 - 2ft section of legs = 48 feet<br><br>Had a lot of fun building this and the entire family got involved. Thanks for the plans!
Thanks for the heads-up on PVC pipe! Materials list changed. The legs do in fact need 48 feet ... 8 legs x 3 segments x 2-feet.
to dang cool !!! where did you get the 4way fittings? I can never locate them at the home improvement stores
