  1. Ziplines, slacklines, tyroleans...all basically face the same anchor load problems. When in doubt, let it sag.
  2. Do the Totem Basics have less range than the Fixe Aliens or are the basically the same design?
  3. This is also why, when climbing, you... a) should never use the American Death Triangle for anchors and b) should set up your equalized anchors such that the angle of the dangle (angle between the two equalized stands) is 60 degrees or less.
  4. Slack lines put anchors under gigantic loads via the following equation: Load = 1/2 * (Wt of person + slackline)/COS(1/2 * Catenary Angle), where Catenary Angle = 180 degrees for a perfectly flat slackline under load As Catenary Angle approaches 180 degrees (taughter slackline), COS (1/2 * 180) = 0, so Load on the anchor goes to infinity. If your Weight is 1 kn (224 lbs), and Load at Failure for a 1 biner anchor = 22 kn, then your Catenary Angle is Angle = 2 * ACOS(1/2 * 1 /22) = 177 degrees If the gate was somehow kinked open, your biner breaking strength drops to 8 kn Angle = 2 * ACOS (1/2 * 1/8) = 172 degrees If you want a 3x factor of safety for a single biner anchor at this weight, then you need a Catenary Angle that is no larger than: Angle = 2 * ACOS (1/2 * 1*3/22) = 172 degrees BTW, the shorter the line, the less spring deflection you've got, the closer the Catenary Angle gets to 180 degrees, and the larger the loads. Longer slack lines, despite adding the extra weight of the rope, generally have lower anchor loads. You might consider using big stainless locking biners for slacklining rather than those light weight jobbies. Don't use clove hitches for attachments either. They can get so tight you've got to chop the tat/rope to get them off. Rewoven figure 8 is good.
  5. So a mysogynist and a hipster walk into a bar....
  6. Oops. Might wanna check that again, Frank. I'm on my way, Gene! FUCK YEAH. GORGEOUS DAY

    Red Dwarf

    So, it's looking likely that red dwarfs, which make up 8 out of every 10 stars in our galaxy, probably have the majority of the universe's habitable planets per Kepler's data so far. What would life be like on such a world? Alpenglow all day long? Beautiful skin, even if you're actually fishbelly white? 9 Essentials? REALLY short (like, 3 days, although there might not be any days with tidal locking) ski seasons?
  8. I think we should one-up The Terrorists . Cut there heads off AND pee in their mouths. On camera, of course.
  9. WILL SOMEONE PLEASE THINK OF THE CHILDREN!!!!!!
  10. Yes, yes, yes, I believe we've all heard that joke... God knows I have.
  11. Can anyone who votes to defund Planned Parenthood (and when you vote GOP, that's what you're doing), the number one provider of health care to poor women, have a right to apply the term mysogyny to anyone but themselves? Even if you're anti choice, a women-hating policy if there ever was one, given that abortion constitutes a whopping 3% of Planned Parenthood's budget, wouldn't you still want to support 97% of what Planned Parenthood does?
  12. FW: the Frank Burns of CC.com.
  13. So you didn't think that was funny I take it?
  14. I actually cracked myself up with that one...
  15. Ya gotta realize, I don't have a cat and a laser pointer.
  16. I'll pee on your back, but that's as far as I go.
  17. Number one stopper? Hell, those things are HUGE.
  18. There's civil engineers and uncivil engineers...
  19. FW doesn't pee at all, he leaves tiny yellow crystals. He also hasn't pooed in years.
  20. I hear ya. KKK asked me to climb with him once, but the caveat was he wanted me to pee in his mouth. Suddenly...my calendar was full.
  21. Oh, I meant real engineers...sorry.
  22. Yeah...In clear weather the wind is often brutal. Bring some shelter unless you want crunchy, uncooked meals and no melt water. And ear plugs for the flapping, snoring, and farting.
  23. Ivan lead up P1 to give her some jug practice before going up the Monkey the next day. P2 might have been a bit much for the poor girl...
  24. Oh, you meant 'morons'. Clear enough.
