Introduction: SplatterFX - Articulated Monster Frame
In this Instructable I will show you how to make the best articulated monster frame on the planet (at least I think so) - each of the monster joints (Splivels) allow for a full range of movement!
I created this project for the Houston HauntCon 2008 as a make and take project. My sons and I had a ball there! I want to thank Leonard Pickel and his wonderful family for hosting this event and allowing me the opportunity to go Halloween Crazy in the middle of May! If you are interested - check out Haunted Attractions Magazine online...
Now! Mr. AMF!!!
Step 1: Parts List
There are basically two main parts of this project -
1. The skeleton/frame
2. the Splivels (it is what I am calling them...SplatterFX + Swivel = Splivel)
The skeleton itself will take you maybe 10 minutes to measure, cut and glue - the Splivels will take longer. All of the parts can be found at the local hardware store, but you can do much better if you order nuts, bolts and washers online or from a store that specializes in nuts and bolts.
For this project, the Monster Frame will be articulated at the shoulders, elbows, neck, knees and hips. You can do more (hands and feet) or less. It is really up to you...
2 - 8' sticks of 3/4" PVC Pipe
2 - PVC Crosses
18 - PVC End Caps
9 - 1/4-20 x 1" Hex Bolts
18 - 1/4-20 x 1-3/4" Carriage Bolts
45 - 1/4-20 Hex Nuts
54 - 1/4-20 Star Washers (Outside Tooth)
2 - 5' x 1-3/8" Flat Plate (Garage Door Strap)
Tools (must have):
Drill with 1/4" Bit
Vise Grips or Wrenches
Safety Glasses (Metal Filings!)
Leather Gloves (Metal Filings!)
Not necessary but helpful/cool:
Bench Vise (this is VERY helpful when cutting the metal plate and drilling the PVC caps)
1 - 3/4" PVC Tee
Step 2: Make the Splivel Plates
This is the hardest part of the project - the Splivel plates. (Wearing safety glasses and gloves!!!) Take the 1-3/8" flat plate and cut it into sections with the hacksaw. Each full section of strap plate will give you 15 Splivel plates (you need 18+). Cut the strap into pieces that have three holes each.
When finished cutting use a grinder or file to take off the sharp edges.
Step 3: Drill
Using the drill with the 1/4" bit, drill a hole in the end of the PVC end caps. (This is where the vise is really helpful!) If you do not have a vise, you can use vise grips to hold the cap. Try to center the bit as much as possible (not super important - just makes the end assembly easier).
This is where the bolt end is going to go.
Step 4: PVC Cutting - Skeleton
You can either use my drawing for the lengths of the PVC parts or you can customize the lengths to make your creature taller, shorter, weirder... I have included a pdf file of all the measurements and to give you an idea of how all of this goes together.
Once you have everything cut, it is time to assemble!
Step 5: Assembly - Splivels
Assemble each of the Splivels - I have attached a pdf file of how they go together to help.
Each Splivel consists of:
2 - PVC end Caps (drilled)
2 - 1/4-20 x 1-3/4" Carriage bolts
1 - 1/4-20 x 1" Hex Bolts
5 - 1/4-20 Hex Nuts
6 - 1/4-20 Star Washers
2 - pre-cut Splivel plates (see step 2)
Repeat assembly for each Splivel - there is a total of 9 in this project. When assembling the End caps and Carriage bolts, make sure that you allow the bolt head to protrude as much as you can. This allows the joints to move freely with the plates. Make sure to tighten the nuts as much as you can and then drip PVC glue into the inside of the PVC cap (keep it off the sidewalls - you just want to make it so the nut can't back off).
Step 6: Assembly - Splivels (part 2)
Once the carriage bolts have been assembled and the glue is dry (usually takes about 30 seconds to set), you can the finish the assembly of the Splivels.
Right now, you only need the hex bolt snug. When everything is assembled, you can lock these down (to keep the joint from moving) or you can keep them snug tight to allow reposing or "dangling" effect.
Step 7: Final Assembly
Once you have all nine of the Splivels assembled, you can start on the final assembly. Assemble the PVC arms, legs, hips, spine and neck and attach the Splivels to the joints. I would highly recommend that you test assemble without glue to make sure that everything looks the way you want before finalizing the Monster.
Once you are happy (I know I was!) - glue the parts together and tighten the hex bolts to stiffen the Monster Frame.
My last step was to attach a Bucky skull to the frame (I LOVE Bucky Skulls!). To create the attachment, I cut a PVC Tee and then I removed the Bucky skull top. The Tee gives you something to secure the skull to.
Also - Happily, Mr.AMF folds up very nicely for storage...
