a homemade "extendable baton"

ok, so when i started this project, i wanted an extendable baton, an impact wepon that could be quiickly deployed and packed small. What i ended up with was more like iron nunchucks, but they get the job done!

a close up of the mechanism... hahaha if you can call it that....


folded up


and in my pocket..

LOL Nice! I actually have a pair of nunchacku made with similar parts. Except i used 12" lenghts of pipe, drilled holes in the endcaps for eyebolts, added a chain, and used little screw type carabiners to join the eyebolts to the chains of each end.

Loved to practice with that, it's quite the workout...

nunchik?

i would imagine it would be a work out hahaha, like i said i hadn't originally wanted nunchakus and they only open/ close one way so they aren't really nunckakus or a baton... it's in between.... @ blutgott nunckauk.... are...

maybe you could find a way to have a sleeve fit over the joint? but the bolts are in the way so that might not work

aye, than put a sleeve, or bar, inside the pipe(they are hollow right?) so when you flip it outwards it comes out the handle end and in-between the joints...very cool idea you had btw, i may have to make one for myself.

This is interesting. I tried something similar, but I failed and decided to forget about it.

Actually With BM's idea you could make the bolts work in your favor. If you put the sleeve on the outside, and dremel a little "L" channel at the top of the sleeve, you could make it so you slide the sleeve up onto the bolts, and then rotate it 45deg to lock it up there...

that is a good idea PB! i had tried a sleeve, but yeah, bolts were in the way, if i did that L lock.... thinggy that would work really well! it'll be a few days before i have a chance to do that tho, i've got a busy work schedule this week

Busy work week eh? Yeah, I know how that goes... Well i'll just wait patiently for the pics!! :)

how about two spring loaded sleeves on each baton handle with groves cut in for the bolts to slide into so when you flick it open both spring loaded sleeves slide into the middleand meet completely covering the middle joining piece? that might work

hmmm i like the way it looks in my head... but i can't figgure out how to hook springs to it..

springs from bolts to sleev externally?

no that wouldnt work maybe someone has plans involving spring loaded sleeves that they are using on their own project? anyone shed any light?

maybe it would work if you hooked the bolts up inside of the handles them selves through the pipe into the sleeves to push the sleeves down together?

or perhaps just a single sleevethat would be easier i guess

I'd probably use a single spring loaded sleeve, I'd run a bolt through the sleeve close to one end, then I'd slot the end of the pipe it would be sliding over, in order to give it a channel to ride into. Then I'd attaching a spring to the inside of one of the end caps using an eye bolt, and connect that to the bolt I ran through the sleeve...

Would kinda have a lot of bolts sticking out, and you'd run the risk of permanently deforming the spring when it's folded in half, but it would work...

bah just grind the bolt heads off and tig weld em in

Do you have a tig welder I can borrow?

You have to learn about fasteners.
first, I would look for a roll pin, or spring pin.

it kind of looks like a short piece of split pipe.
instead of using a bolt with a head.
you put a roll pin in the hole, and it's a tight fit,
but if you countersink the outside holes
you can put a drift punch into the roll pin
and flare out the ends, sort of like a homemade hollow rivet.
or pound a nail into the roll pin
(like when you look at the top of wooden handled hammer.
there is a little metal wedge in the top.)



or

Flat head press rivets,
Think like a big brass nail on one side
that force fit presses into a hollow nail on the other side

You can buy them through knifemakers supply
you just have to find one the right size.

One set works like this I------ ======I

It is possible to buy more than one set, and cut the head off the hollow pin
and combine them to make a longer pin
like this I------ === ------I

you may have to make another set,
with smaller holes to match the press rivet diameters

got a tig, a mig, a mma, and gas welding and cutting equipment. come over and use em if ya want phyre XD

ROFLMAO...

I may have to take you up on that one of these days...

do it dude!

How long is it?
You should add a locking mech if you havnt already so when u go the KO someone it dosnt pivot back and KO you.
