Reslinging BD Gen2 Cams
|
I've got a full rack of Gen 2 BD cams (sling is through small rigid metal eye at end of cam stem), that have seen light use but still have ~15 years of age. I was thinking about reslinging them with cord, and the local climbing shop recommended using 8mm cord if I can get it to fit. Is that really necessary? I was hoping to put 2-3 loops through and then tie off with double fishermen's; that way I can clip to my rack short and then extend. - what minimum cord diameter would be acceptable? - will 3 loops cause issue with the cord cutting into itself when extended? - would webbing work better? I was worried that I'd have issues with webbing knots loosening over time, hence my gut reaction to use cord. Cheers, Hamish |

two loops of cord will give you plenty of extension, but you'd have to use 6mm tech cord and a triple fishermans, which would be pretty bulky compared to a sewn runner. I'm not sure if you could get even two lengths of 7mm cord through the "eye". 9/16 webbing with a double fishermans will also work, but only for a single loop. Don't use a water knot with webbing unless you leave xtra tail and check it frequently...again too bulky. Or you could send them to Yates for $6-$7 per cam (single loop sewn dynema runner)...stronger and less bulky.  |

Send them to me. I will resling them with cord and provide feedback on their performance. Next time you want to resling cams you can make an informed decision. |

Plenty of companies resling cams for $3-$7. Why not just get it done right? Metolius reslings and cleans your cams for $3 each. It's so cheap. Ebmudder: what's the extra cord/wood for on that 4.5? |

If it was doubled for extension and then you took a whip, the cord could cut itself around the eye where it is crossed over itself. I would recommend getting a nylon loop to resling it like original and BD will do it for $5 bucks or so plus shipping. Look it up on the warranty page on their website. |

Hamish, I had three of those cams sling with cord for a few months before I got them properly reslung. I used 5.5mm titan cord with a triple fisherman's knot. It was a pain in the ass, just save yourself the effort/annoyance and get them reslung. I used Caccia Equipment and the service was great. I definitely would not double up the cord - as Jon mentioned, it can self-abrade when high forces are applied. |

I'm not sure if BD placed the holes there for weight savings or what I'm using them for. BTW, while the dowel slides in and out of the lobes fairly easily, it does bind against the stem (when inserted through both sets of lobes), and is a bitch to remove one-handed...you defintely want to "unlock" the cam before you need it. |

Common thing to do with the bigger cams. We use a short piece of coat hanger in a similar way and positioned so that when you squeeze the trigger, the hanger usually slides out by gravity. |
