In this Instructable, you will learn to make movable, lockable joints for Halloween prop limbs. With this you can make your own skeletons, and with some extra work, a massive monster freak like this guy!

Step 1: Tools and Materials

Parts

 

1 inch shc 40 pvc pipe

1/2 inch sch 20 pvc pipe

1/2 inch fittings

6-32x1 1/2 screw with nut

8-32 set screw

1/8 inch rod

5/8 inch long nylon spacer

 

Tools

 

pvc cutter

8-32 tap

1/8, 9/64 inch drill bits

drill

saw

alen key for set screws

5/16 wrench

screw driver

belt sander

super glue

 

Step 2: 1

Sand down any bumps and lettering on the fittings.

Step 3: 2

Mark on both ends where the shoulder on the inside of the fitting is that stops the pipe. Make another mark, 1/8 inch from the opening, all the way around on one side. On the opposite side, mark the end with two lines that just touch the opening of the fitting and are parallel. If using an elbow fitting, draw the lines on so that when the fitting is resting on it’s side, the lines will be horizontal (I did it wrong in the photo).

 

Step 4: 3

Cut on the line that is 1/8 from the end and keep the ring that you cut off. Make the cut as clean and straight as possible. If you have a belt sander, you can straighten up your cuts.

 

Step 5: 4

Cut from the lines on the end down to the shoulder line you drew earlier and cut out the area between the cuts so you have two ears. Make sure you cut to just outside the inner surface of the fitting. Drill a 9/64 hole in the middle of the ears.

 

Step 6: 5

Cut a ring of 1 inch pipe the length of one end of the fitting to the shoulder line you drew. Lay the ring on it’s side and cut a slit down its side.

Thank you very much! Unfortunately, the rest of that project was "how am I going to do that? I'll try that. Wow I can't believe how well that worked!" If I ever do another project like this, I will make an Instructable as I do it.
