Title: Carbon shaft "joiners"
Post by: calgarychef on January 31, 2017, 10:47:00 PM
Here's a strange one

Does anyone make an adapter to screw one arrow shaft to another "insert to insert". I'm looking to make some lightweight takedown tent poles by joining two or more arrow shafts together.

Could easily be done with 2 inch long sections of 8/32" threaded rod.  Maybe glue/solder a washer in place at midpoint of section for a stop to butt insert(s) against.

Do a search for takedown arrows.

Rob D. had a pic of one he put together!

I know you said takedown; but if you don't have any luck with the arrow shafts; I used electric fence rods from Tractor Supply. They are $1.00 each and 4ft tall. They worked really good for burlap blinds.

I would think glueing sleeves on them would be a much simpler approach.  Similar to those found on nearly every tent these days. That way you wouldn't have to worry about dirt in the threads or adapters getting stuck.

Good idea but doesn't work if the joint will be flexed much or put under a stress load. I tried doing this with carbon shafts a couple years ago. The shafts and inserts hold well. The problem is the 8/32" all-thread (I used stainless) which simply doesn't have the strength to prevent eventual bending under serious and repeated flex. Well, it didn't in my case anyway.

It would be nice if someone would make them out of hardened steel. There's all kinds of gizmos that we could make with broken arrows.  I use carbon shafts for a bipod for shooting my thunder bow  ;) .  I've also made a carbon tripod for my optics. These things are super light and strong.

For such things as tent poles, etc, it seems to me that a sleeve would work better than an insert.  I've read from time to time on here about people matching certain aluminum arrow sizes with carbon outside diameters for use as footings.  It seems to me that the same thing would work for joining two shafts together, if it wasn't important to have a seamless joint.

what if you did both?  put a footing on one arrow(aluminum arrow of the proper size) and make it about 10" long, that way you have 5" of footing on both arrows and then jb weld some of the 8/32" rod into an insert so it wouldn't move.  then join them together when you're ready.

If you buy a single aluminum arrow, Easton X7, of the correct size you can make all you need, and that aluminum is over 100,000 psi in strength.

On one tent with fober glass poles, I found that the joints were the exact same size as 2317s.  No longbow shooter in their right mind has any use for 2317s, i had some that were given to me so I put them to work.  They were stiffer than the orginals by far.  some of the skinny lightweight aluminum tent poles are severely liable to cracking.  Carbon arrows may be stiffer than some tent designs would want to work with, but they would be stronger.  You can use the 8/32 thread, I would put a single nut in the middle and hit it with a dab of locktight and round the corners.

I make no claim of being in my right mind so I guess that is why I think 2317's are great d/r longbow arrows.
