OK, I've seen like 3 posts on homemade chucks this past week, so here's a compilation of all the ones I can find on this forum (if you know of more, please post links and I'll add them)

Here is a picture of my cutom made 11" freestyle nunchaku or "WHIP CHUX"

Bottom View:

And this is the disassembled view when I changed out those ratty cords after 3 yrs of rigorous use. These nunchaku are old, but they are the best I ever used. They'd better be because they are my design. You can see all the niks and dents on them. They are even slightly bent from practicing striking various materials a long time ago.

I can give specs if anybody wants them.
Subzero's Aluminum Chux

these are my chucks






i made them cutting an aluminium tube for the 12" sticks
added plastic tubes that perfectly fit inside them to add weight and thickness (needed to hold the pins that lock the chain)
then i made the holes and hammered the metal pins in them, passing thru the chain
in the original idea i thought to cover the aluminium sticks with an hard rubber tube for more weight grip and diameter, but i really like the way aluminium sticks look 
they are ~7/8 inch diameter, do you think i should add the rubber tube?
total weight: 290g

If you want to begin learning to do nunchucks these, are in my opinion, are safest and easiest prop to use. When learning, I pretty much exclusively practise with my GlowChux.
Then when you want to do something special you simply load a fresh pair of glow sticks into them and go mental. Also the GlowChux, when mastered, can be as impressive as the fire nunchucks due to the trails left by chemical glow sticks. And you can throw caution to the wind and push yourself to the very limits of your abilities.
The picture below was taken with a single set of glow chucks on a 2 second exposure.

They are also a lot easier and cheaper to make than FireChux.
All the equipment and components to make 3 sets were purchased from Homebase for just under �4 and I made my first pair sitting at my desk in my room at Uni.
Equipment
Hack Saw
Drill
Craft knife
Components
1. Soft plastic overflow pipe about 19mm diameter (you need about 24 inches of per set)
2. Washing line cord
3. Lots of Ducktape 
4. 6 inches of chain small enough to fit inside the tube
5. Lots of 6 inch glowstix (buy them in bulk from HomeOfPoi for �34 per 100. That works out at 70p for 6 hours of glow)
Assembly
1. Cut the tube into 2 12inch sections.
2. Use the drill or craft knife to bore a hole 1.5cm from end A and a hole 4cm from end B. (both holes should go all the way through the tubing)
3. Put the chain into the tube at end A and put the washing line through the hole and through the first link in the chain tie the washing line around the tube and wrap in Ducktape.
The chain should now be firmly attached to the tube - repeat with the other tube and you should now have a pair of nunchucks and are essentially done.
4. The next step is to attach the glow sticks to end B of each stick. This is a step you will have to do every time you want to replace the glow sticks.
Put the glow stick into the tube at end B till the loop at the end of the glow stick is lined up with the hole. Put some washing line through the hole and the loop at the end of the glow sticks and tie it off again. Wrap in Ducktape, repeat for both sticks.
Well done, you have now got a pair of GlowChux and they should look something like this:

Tip: to crack the glow sticks, use the nunchucks to strike a hard object you can hit very hard. The GlowChux won�t break and its a cool way to get started.
Note:- recently I had two incidents with my glow chucks breaking, I had best explain firstly the washing line cord that holds the chain on will wear through eventually. I got around 6 months use before I needed to restring them so check the cords if your using them where there are people around.
Secondly, make sure that you use the correct type of glow stick (like the one pictured below).
The important thing is the attachment at the top is strong enough to take the large amount of G-force they will experience when been used.

I recently got some different sticks from my normal supplier and they broke and flew out within 5 seconds of starting.

Bungee Addon
Out of all of the silly toys i've invented this is definatly my favorate. Its simple to build durable looks awsome and has masses of potental for moves and tricks. if you haven't guessed im talking about Bundgy nunchucks!! 
These are very easy to build firsly you need to make a pair of Glow Chux these will be the basic chux used of course you can use any pair of nunchucks but make sure there light and preferably foam.

once you've got your chux turning them into bungy chuxs is very simple firstly you need to get a length of elasticated cord around 1m is about right i use underware elastic from a sewing show but any elasticated cord would work. next attach the cord half way up one of the chuxs and tie two loops at the oposite end of the cord.
To use the bundgy chux put the end loop around your wrist. Next put the second loop around your hand but not over your thum so that the cord going to the chux should be attached to the center of your palm.


congradulations your ready to Bundgy chux enjoy

Ok, here is my first guide on how to build my favourite fire toy *drum roll*
Flaming Nunchucks!
Now, before I start I'll just say if you've not done nunchucks before these are not the props to learn with. Even if you've done fire poi, staff or anything else before, if you learn with these YOU WILL BURN YOUR SELF I SH*T YOU NOT!
I would recommend you build the GlowChux first then once you can do those without messing up move onto these. However, once done, these look very cool and if like me, you enjoy looking like a mental nutter, you'll enjoy using them.
Below is a picture of me using two sets of fire nunchucks on normal exposure.

Equipment
Hacksaw
Pliers
Power drill
Bench clamp (not absolutely vital but if you want to try drilling through metal without one, you're a braver man than me)
Glue gun
Components
1. Metal tubing approximately 19mm diameter approximately 30 inches long (towel rails are perfect)
2. A length of chain (ensure that the links of the chain will fit inside the metal tubing) you need it 6 inches long
3. Kevlar wick (get that from HomeOfPoi or Firetoys websites) the wick should be 2.5inches wide and 1 meter long
4. A length of wire (the stuff used in gardening that is covered with a plastic coating is perfect but you'll need to cut the plastic coating off first). The wire needs to be rigid stuff that can be bent with force but will hold its shape when you've bent it.
5. Tennis racket handle grip. Allsports normally sell a pack for £5 that has two grips in this is perfect as you need to cover two handles
6. A roll of electrical tape
Ok, if you've got all that then we can begin.
Assembly
1. Cut the steel tubing into two 15inch sections these will be the handles.
2. Next you need to drill 3 holes each big enough to fit your rigid wire through and should go right through the tube and out the other side.
The first hole should be 1.5cm down the handle from end A. The next holes should be 5cm and 3cm from end B and again should go right through and out the other side.
Repeat for the other handle.
3. Cut off 50cm of the wick and wrap it around end B. The next part is difficult but you'll just have to keep at it. Bend a piece of the rigid wire into a U shape and push it through the wick and through the two holes in end B and out the other side.
Then bend the two protruding ends down parallel with the handles to ensure the wire won�t come out and cut off the excess. The wick should now be firmly attached to the handle repeat for the second handle.
4. Now put the end link of the chain into the end A of the tube and put the rigid wire through the hole and through the end link of the chain so that the chain is now attached to the nunchucks.

Now bend the wire round the tube so that it can't come out. Do the same for the other handle and you now have a pair of nunchucks but we're not quite finished yet.
5. This is neatening up: wrap the rigid wire wrapped around end A in electrical tape and wrap the handle in the tennis racket grip.
The important thing here is when wrapping the handle start a 1/3 of the way from end B and work your way up to end A. Its important that you wrap it B to A so that it wont grip to your cloths when it slides over them.
6. Use the glue gun to fill in the ends of the tubes where the chains come out. Try and make sure the glue dries with the chain perfectly centred in the tube this stops the chain wearing against the tube and prevents them from taking bits of skin off you when you mess up.
Congratulations! you have just finished your first pair of Flaming Nunchucks and they should looks something like this:

Just_A_Swingin's Wooden Corded Chux
[/b][/size]
Big ellos to all you Stick Swinging Maniacs 
Just like to show you all a idea i came to on making cord nunchak's
Most of the time we hear of everyones cord chucks becoming frail and after a period of time they snap..
Well ive came up with a little idea that has made my own chucks last quite a while
Basically you take your standard 12" wood chucks
at the 'top end' take a drill bit that is roughly 10 mm shorter than your wooden chucks and drill and hole 5 inches down into the wood 'as if your going down the handle'
next i took a piece of very heavy duty climbing rope 
threaded the rope down both sets of handles
get 12 small screws.. and screw '3' screws into either side of each nunchaku
Done, takes all of 15 mins to make
This is my eyes gives you a 'Stiffer' cord.. which if you do try and practice with it does help you out swinging, perfect for rolls and never 'pinches' you
Give it a try..
************************************************************************
I shall be getting some vids of myself uploaded soon.. i'm not the best but i can do a few moves

Hey everyone, welcome to my Tutorial.
I'm gonna show you now how to make a
low-cost and light glownunchaku in a short time.
Please read the whole article before start building.
Warning: Making nunchakus is forbidden in some countries. If you don't have the permission
don't blame me for problems with the police. Building at your own risk.
What you need for two Nunchakus
* 1x round hardwood staff (length: 1m/40inch , thickness: 22mm/0,87")
* 1x nylon cord (length: 1m/40" ~ thickness: 3mm/0,12")
* 1x nylon cord (length: 20cm/7,9" ~ thickness: like a hair)
* 1x drill with a charged accu
* 2x jagged bit (thickness: 3,5mm/0,14" and 4,5mm/0,18")
* 4x glowsticks (length: 205mm/8,1" ~ thickness: 5mm/0,2")
* 1x soldering iron or lighter or knife or scissors
* 2x strong tape (length: 10cm/3,9")
1. Cutting the wooden staff

Just take a saw and cut four sticks with the same length from it.
Keep in mind that the nunchakus can't be seen when it's dark.
After you're finished they should look like this:

2. Drilling the holes
Now you have to drill holes in one side of each woodstick.
On the drawing below you should see what I mean.

Once you're finished with doing this step on every four woodsticks, continue with
the other side of them. For this step I've made a real picture.
Try out how you can do it but always watch out for your fingers!
I used the small jagged bit, after then the bigger one.
You need to have two indentations at the lower side of the woodstick.

3. Pulling cord through the holes
This is a step where you maybe need a little bit patience.
Just look at the pictures below and copy it.

Start with the lower hole (stick1), go through the upper hole (stick1), make a simple knot

Then pull the cord through the upper hole (stick2) and the lower hole (stick2), make a simple knot.

Now find the right length of your cord, make strong knots at each side and cut it with a tool
of your choice (I prefer soldering iron)
4. Attaching the glowsticks
Crease the glowsticks so that they illuminate. Then put one and in your drilled hole and fix it with the tape.
Now bent the glowstick over with the end in the second hole and wrap the rest of the tape around the nunchaku.

When they aren't bright enough at the next time you want to enjoy the effects just pull on the black tape and
replace the old glowsticks. If you want you can also use four or more of them, just be creative.

Hopefully this tutorial wasn't a waste of time and you can understand
every point I explained. Have fun with making your own nunchakus.
If you have problems with some parts just post in below, thank you.
