Twisting in Bib Hangers: Not this way.
There have been reoccurring reports on shaft twisting inside Bib hangers.
Predominantly oval shaped shafts seem prone to this, and I fall into this category. Add to that a tapered shaft, and hanging with a clamp style hanger will probably get too tricky at some point as pulling force (weight) is increased. It did for me with the Regular Bib, which I had to give up on at around 15#. That was 1.5 years ago, and now I’m giving it a try with a modded Bib Starter.
After experimenting with settings, I found that wide apart on the basal screws works best for non twisting of my shaft. But it can still happen because the angles can’t align perfectly symmetrical. It wasn’t until I read about xenolith’s triangular Bib setting with 2.5” basal screws, and swapped a few notes with him, that I realized his plastic parts are not pre-fixed to the basal screws (xeno hasn’t confirmed this to me; maybe because it seemed too obvious, I don’t know).
Anyway, what I then realized is that I should scrap the hinges and run screws straight through the plastic parts. Structured fundamentally like an AFB but with two basal screws. I have wingnuts on left and right side of the bottom basal screw, and no wingnuts on the top basal screw. What happens, with the top teeth partly or fully engaged, is that the top basal screw will ride along when winging the bottom basal screw nuts. So much actually, that it toes in - instead of out, which I want - that I place two nuts on the top basal screw (inside the plastic parts) to keep it toed out.
With the plastic not not pre-fixed to the basal screws, I prefer to place the skids on a thick book to keep the parts steady and high, and with the shaft in position pinch the plastics together; semi-tighten the top screw, checking alignment and then tightening on the bottom basal screw. Hang a light weight, and then tighten the top screw the last bit.
While I can’t prematurely say I’ve found my silver bullet for hanging high weights, I now no longer twist inside the Bib, at all. I seem to be able to hang longer before numbness creeps in. i second xeno’s report, that triangular settings makes hanging very comfortable. I don’t know when this forehead slap would have come to me, hadn’t he stated that the “basal screws don’t bend”. Thanks xeno!
It’s been a while since the last twisting in BH thread, and I don’t know if everybody else is already modding their Bibs this way. But just in case they don’t, they may want to try it.
