So I recently picked up some carbon fiber toggles for hitching my whoopies to my tree huggers and they keep cracking! Am I doing something wrong or are these just something one should generally stay away from?

Put the amsteel on the knot and not on the toggle….. that may be the issue?Originally Posted by barchetta

That makes sense shug. Thanks!Put the amsteel on the knot and not on the toggle….. that may be the issue?

Note that Shug's toggle isn't carbon fiber. I use aluminum arrow blanks, small tent poles, or cut up knitting needles. Even wood dowels resist compression better than carbon fiber tubes, which are built to be strong lengthwise.
I use carbon fiber. So if they were going to break...it'd be by my excess mass.
So I know they work (when used properly).
I will also add that carbon fiber comes in different wall thicknesses and strengths.
Trail sticks can work too. Its a nice project to whittle a set, customize them with your name or designs.
Regardless of what you pick, shugs advise is always good. "On zee knot and not on zee toggle."

I'm with shug. Placement of the amsteel is the ticket! I use carbon and never had a problem
I have used the cut off shafts from graphite gold clubs for 3 years now with no issues. I have used the grip end, so they have thin walls and I have never had a problem. I do hang on the knot not the toggle as Shug showed. When done this way the force exerted on the toggle is compressing from all sides. I have also used the aluminum arrow pieces, but I prefer the golf club shaft as it is a larger diameter...looks to be about the same diameter as Shug's piece of aluminum.

The other issue is direction of the fiber. As WV pointed out - carbon is directional. You can get carbon primarily oriented lengthwise, around the shaft as a ring, or in a diamond braid. Rings would be most resistant to compression while lengthwise would be least. I expect there is a significant side load on golf club shafts so they will be diamond/ring oriented. OTOH arrow shafts are made do transmit the force on the knock to the tip so mostly lengthwise orientation thus more susceptible to compression cracking.
YMMV

Free advice worth what you paid for it. ;-)
Exactly!
I've used pultruded and lengthwise oriented carbon tube and CF arrowshaft quite a bit in guitar projects, and they are not at all strong in 'crushing mode', but very stiff when loaded lengthwise.
A plain piece of hardwood dowel may be a few grams heavier, but will do the job better IMO. A stick from the campsite would do just fine, though you may not want to hunt for that, if it is getting dark and you are tired.
I just made up a whoopie suspension with toggles made from an old golf shaft (a driver shaft (stiff flex (I guess that makes a difference (oh sorry .. I digress..)))). Carbon Graphite golf shafts are some of those that have a cross-hatched design for torsional strength, and also wound fibers as well as loongitudinal ones, all mixed up with resins. Mine work like a charm!
Not sure I'm too crazy about the arrangement yet, though.... a good bit of fiddle factor with these things. I think maybe my whoopie slings are too short with 3 ft max and only about 2 ft cinch factor.
But the toggles are NOT the problem. Go by a golf shop and you can probably get an old shaft for free.
