giant halloween spider

by:Yucai     2020-04-21
Let\'s face it -
Every house needs a giant spider for Halloween.
Not \"oh, a terrible spider fell to my head when I went to the front door\", but a spider --
I\'m talking about the kind of spider that \"the furry black beast just ate my dog.
This is not that big (
See last photo)
However, this design can easily be enlarged to very large props with larger materials.
This design is based on the spider we made a few years ago and has been modified to minimize the number of pipe fittings and to flexibly add your own body shape and size.
We used 1/2 PVC pipes because we had a lot of off-
Wounds left over from the gardening project
I might choose 3/4 if starting from scratch.
Given the number of leg joints, you can also pose the spider in a different way (
Just like getting ready to grab the front leg of a passing child)
Or omit the last part of each leg so that the spider can lie flat on the ground.
We found that this configuration is more suitable for suspension in the web. MATERIALS (
All PVC pipes are 1/2 and you can zoom in as needed).
The approximate price shown by the small hardware store-
You can find better prices in the big box store.
The price is the price of all components, not the price of each component.

Inch pipe section-
These will be the pillars from the central spine to each leg. Cut 3 x 3-
Inch pipe section-
These will be added to the spine for each cut 1x12
Inch pipe section-
This is the \"tail\", using PVC primer/glue, glue 1x5-support the belly of the Spider
Inch pillar and 1x3 on both sides of PVC \"T\" accessories-
The inch segment entering the center of \"T\" is now repeated with each 2 x PVC \"cross\" accessory-1 x 5-
The opposite side of the inch pillar into a cross, 1x3-
Put the inch segment into the center hole and repeat the last cross-installation, this time using 12-
Tail in inches, not 3-
You should now have 4 x spine ready to join.
All legs and pillars are parallel, which is crucial
Then, when I was stuck on two blocks, I looked up to make sure they were all on the same plane.
Apply primer and glue in the middle of the \"T\" accessory and in the corresponding holes of the next accessory.
Insert the accessories together, twist 90-
In order to get a good joint, it is then fixed together on the raised block of wood so that the pillar is placed on the same plane.
Repeat all 4 x spine once.
The last step will be a 90-
Degree the \"elbow\" to the end of each leg pillar.
It is important that each elbow is perpendicular to the spine and I find that the easiest way is to insert a dry longer tube on the side of the elbow and not stick together, stick the elbow to it and rotate the tube when wet until it reaches 90-
Spine cutting 24x2 degrees-
Foot section-
These will be fragments of the legs (3 per leg)Cut 8 x 4-
Inch pipe section-
These will be parts that connect the legs to the spine using PVC primer/glue, glue 2x2
Leg segments to each side of 90-
Elbow accessories. Repeat 8 times. Glue 1 x 2-
Leg to 45-
Elbow accessories. Repeat 8 times.
Now the segment connected with 90-glue
45 degree elbow to a section
Each end has an elbow.
Make sure that all pipe segments are parallel on the same plane and with 45-
Point the elbow inward. Repeat 8 times. Glue a 4-
45-inch section on one sidedegree elbow.
Now stick this to the other end of the leg assembly, make sure 4-
The inch segment is parallel to 2-and in the same plane
The foot across the leg. Repeat 8 times.
The last inch of sand 4-
Inches of each leg to allow a more loose dry fit to the \"hip\" elbow attached to the spine. Insert the 4-
The inch segment at the end of each leg is inserted into the \"hip\" elbow accessory attached to the end of each pillar of the spine.
When you insert the leg, rotate the leg to make sure the leg seat is plugged into the accessory all the time (approx 1-inch).
Position the legs to the final shape you intend to pose for the spider, usually the body four legs forward and four legs back.
Once satisfied with the position of the leg, drill a 3/16 hole inside the hip leg fittings and leg segments.
Drill about 3/8 below the end of the accessory.
I decided to use the old packaging materials I put
You can use almost anything as long as you are light, waterproof/durable (
Spiders may be in the outside elements).
Belly for spiders.
As long as it is large, round and light, it can be made of anything.
Beach balls or balloons are ideal.
Other Spider builders also made glass balls.
I think beach ball is easier :)
Our Spider uses a plastic garbage bag filled with foam to wrap peanuts and \"molded\" it into a spherical shape with adhesive tape.
Attach the abdomen to the tail of the spine with tape or similar.
Try filling the main crack with tape.
Chest for spiders-
As long as it is fairly firm and long enough to overlap the front of the spider, it can be made with almost anything.
I used some polystyrene foam and you can also use a plastic bag filled with crumpled paper, cartons in plastic bags etc.
Attach the chest to the spine with tape or similar.
Continue to tie the chest, abdomen and spine together.
Start spraying sealed foam on the outside of the spider.
Make sure you use a random pattern as it will continue to expand and set to the shape you spray.
The more random your pattern is, the more \"organic\" the final skin will look \".
Don\'t try to sprinkle after spraying the foam, just spray it and make it full.
You can rotate and keep spraying when each side is dry.
Slide the nail into the end of the spray tube to prevent it from setting up in the tube between applications.
Be careful, there is no sealed foam on your clothes or hair.
It is very sticky and only removed with acetone
Not good for any surface.
After the foam dries, spray the body and legs of the spider.
You may need to turn over the body twice to get to all the corners and gaps.
Before spraying, place the masking tape on the last inch of the leg so that the fit of the body does not become tighter (
Remember you polished this in step 3).
Remove the tape before assembly.
Check the spider to see if there is foam blocking the \"hips\" attached to the body \".
Cut off any foam with an Exacto knife or similar knife.
Insert the legs, pins, and resend any missing parts. Voila!
The biggest spider nearby
Spiders can be enlarged with larger diameter PVC pipes and longer leg segments.
The picture on this page comes from our big brother Spiderhe has 4-
Leg segment, 4-
The abdomen is as big as a car.
This lets you know how to modify the basic design in this manual by removing the last leg segment to make it flat on the roof, network, etc.
Some other ideas and options :-
Create a face and add horrible eyes and teeth
Buy the pipe insulation sleeve and slide over the legs to make it thicker
Rotate the front leg back to make the spider \"back \"-
Continuously shorten the last paragraph before and after each leg, so that the body angle is upward, ready to jump-
Stick marble or glass beads to the front of the \"face\" of the eye
Please attach eyes if you intend to pause the spider
Bolts, or bolts similar to the center of the spine, extend down through the foam to the outside of the body so that a rope can be attached to bear the weight. I found an old skull prop and decided to go for the effect of \"human skull bursting from the front of the Spider.
The steps are simple :-
Space for the skull
Hot glue-
More spray foam
Make sure it runs back from the body
Cover the skull with painter\'s tape
Spray the new foam Red
