Was looking over the post and noticed a mistake.  There is about .01 inch of play between the halves and the swivels, not .001 as first noted.  I wish I could get that close, but I'm only a mere mortal...

danceswithsticks, some solid titanium chucks would be pretty awesome!  Light weight and strong as all hell!  They might be light enough to actually use Smiley

If anyone wants, I have a PDF drawing of the swivels with measurements.  .750 is a little on the thin side for chucks, but the drawing could be easliy adapted for 1 inch or even 1.250...  square steel tubing is redily available in many sizes Wink

I think you should make some more u-swivels and sell them to people who want to make their own nunchaku with u-swivels. I'd love to make my own u-swivels, but I don't have the tools I'd need... But it would be really cool if I could buy some u-swivels and make my own homemade(wooden, not fully stainless steel, although that is awesome) nunchaku with u-swivels

Thanks!  I'm going to make another set to see the time involved, then figure on what a fair price would be for them.  I have no idea how long it took me to make the first set, I worked on the sticks a little, then the swivels a little, and so on. 

Would .750 inch or 1 inch be a better size?  I know most of everyone uses 1 inch sticks, but the .750 inch on the diagonal is right at 1 inch, so there would be no swivel "hanging over the edge".  The 1 inch would require alittle more work, but is easily doable.

I'll see what I can come up with.....

 respect  I am very interested in this, they should be .750 inch, with rolled pin so it can be punched thru for chain swaps, a concave hole set that fits a tapered screw head for attaching to stick, and the edges filed down so that they are not sharp. The blueprint for the old Dolan's U- swivel is posted on Woodall's website, I would gladly purchase a bunch of those from you!

Yeah, .75 inch would be better, and I agree with everything else stickman said.

I am going to go to the machine shop that drilled the holes for me and inquire about the cost of some counter-sunk holes in the bottom, as well as cost for drilling a bucket full of them (should be very little, especially for a bunch of them).  I had intended on putting roll pins in mine, but I decided to go with solid pins since everything else was made of solid metal.  I may still file down mine but the next batch will be more rounded...I had thought about the swivels biting or digging into the hands during rollovers, but as mine are so heavy I wasn't too concerned with that.  I had intentions of putting washers on mine as well, but I went to a lot of trouble to make sure the ends and swivels were polished and square as could be, so there was no need.

I plan on making about 10 sets for the first go around, with all the mentioned improvements, i.e., counter-sunk holes, roll pins, rounded edges.  I'll leave it up to the purchaser to procure the screws and washeres. 

Thanks for all the interest and the suggestions!  I'll post more as soon as I get a price and expected completion date.

Sorry, J-man, I believe I got the only pair from our brother Parker, I have tried to reach him many times, but havent been able to. He worked with me to make a super smooth U-swivel, we were working on the clevis loop when he suddenly vanished, I would really like to work with him again.....    hmm

Two pieces of .750 inch steel hex bar, 12 inch length. 


Chain is 5 inches from pin to pin. 


The swivels are fashioned from .750 inch SS square tubing with .120 inch wall thickness. 


Pins are .187 inch steel braded over on the ends.  The chain is .090 inch steel wire wound into .340 ID rings.  Total of 57 rings in all! 


The Total weight before filing the grip section was 1,575 grams.  I’m not sure how much I lost in the filing, but it wasn't much...
The grip section began with eight .125 inch rounds filed out at .750 inch intervals starting at 3.500 inch from the pivot end with three smaller triangular file marks centered at .375 inch between the round files with one on each side at .125 inches.  All in all, there are 174 file marks on each half of the nunchaku.




My inspiration for the grip section was the edge on a serrated knife.  It looks really nice and provides very good retention…although at 1,575 grams, I’m not going to be slinging these things around much…  but if I wanted to they are ready

I had the ends of the halves drilled and tapped for a 1/4x20 SS screw and the u-swivels drilled with a .187 inch and .250 inch drill at a machine shop.  Everything else was done at home with either a dremel (the halves began as a 28 inch bar and were cut down to the final 12 inch each with a dremel and polished on the ends with 600 grit sand paper) or a hand file.



When the holes were drilled and tapped, I inserted a .210 inch steel rod into the hole and cut a piece appropriate for the 1 inch screws so that when tightened down snug there would be about .01 inch of play between the halves and the swivels.  Then I removed the screw, applied red loctite and reinserted the screws.  Those screws won’t be working loose anytime soon!



I hope you all enjoyed the build guide and pics!  This is just something to hold me over until I get my Woodalls in June!
