    RADS Theoretical Ratio

    Hmmm, my bad Reg, looks like I 'read' stuff into your comment that wasn't there. Seeing your clarification, I agree 100%. And regarding the vids, thanks much for the kind words - that means a lot to me.

    In fact, here's the RADS vid; I had it private, but now it's public: http://www.youtube.com/watch?v=v1p-xuZNq5g

    RADS Theoretical Ratio

    Reg, All due respect, but you have to be careful about how a redirect is connected to the load. If both strands come back to the load, i.e. the climber, as in a frictionless DdRT, each strand only experiences half the climber's weight. So if the climber has to hold himself in position, or lift...

    RADS Theoretical Ratio

    TLHamel, You are seeing a 2:1 because you are ground referenced. You don't move off the ground at all, so you are ground referenced. The system is not supporting your weight at all. If the system had you fully suspended, there would be three lines supporting your weight, not two. When you pull...

    RADS Theoretical Ratio

    [ QUOTE ] Ok, rads is 2:1. Ddrt by the same logic is 1:1. What would we call SRT? [/ QUOTE ] I gather your statements should be taken to make a point rather than actually claiming the ratios to be factual? RADS is a 2:1 to a ground referenced person; it is 3:1 to the climber. I can prove...

    [ QUOTE ] Hey that's cool..if you got a lil extra time on your hands I would love to get together and see your protype try it out maybe...just a thought if your free and in town on the weekend! [/ QUOTE ] Hmmm, good idea, check your PMs.

    Moss, I've shot horns up over a thousand times - likely David has too - there is no snag issue because the line runs over the head. I may have had a snag or two, but then you have too with the horns down. I fully agree with why you shoot horns down; I don't want convince anyone to shoot a BS...

    I have never had a tubing break at the horns or snap back. In fact, I've been shooting horns up with both pieces of tubing with small tears at the horns. They still didn't break after hundreds of shots with them like that. What I'm getting at is tubing breaks from at the horns is extremely...

    [ QUOTE ] Snap back in the face is a good reason for horns down. [/ QUOTE ] I've had all kinds of misfires, some purposefully induced to see what would happen; I've had multiple tubing failures and of all of those, out of thousands of shots by me personally and even more counting a buddy using...

    I wish I could claim something like stablization, etc., but as I recall, I made it horns up because....hmmmm, I'm not sure why I did it that way??? But I do like it. I'm leaning toward horns down on the BS version, but I don't have any real good reasons to do it that way other than that's the...

    [ QUOTE ] Cool. What happens when the throw-line gets wrapped on the end of one of the "Y"s because the line is feeding over instead of under? Looking down the barrel might not be the best place to be? Have you thought of inverting it the way a Big Shot is when correctly used? [/ QUOTE ] I...

    RADS Theoretical Ratio

    OK, Dave, you're embarrassing me. , but thanks for the kind words - not so sure I deserve them but I do appreciate it. I had the thought on the way to work this morning that a RADS analysis might be good, so with your encouragement, I'll try to get that done this weekend. But it's not just...

    RADS Theoretical Ratio

    I'm sorry treebing, I must have missed your original description of what you set up. Still not real clear what the set up looks like, but if you are absolutely sure the system is a simple pulley system, by the definition of a simple pulley system, then counting the lines supporting the load...

    [ QUOTE ] Are you talking a wrist rocket set up. What size beanie would you deploy if a hand model like that? Really looking forward to your model of this type. So much easier to handle than the poles. [/ QUOTE ] No, that's not even close; it will be a full size unit, fired very much like...

    [ QUOTE ] Correct, the scale read 26 pounds. [/ QUOTE ] Whew - I like it when theory and 'real' agree!

    RADS Theoretical Ratio

    [ QUOTE ] the only ratio that matters is the one relative to the person doing the pulling. The only measurement that matters is in relation to the person doing the pulling. RADS is a climbing system and so the ratio would be relative to the climber. I dont see how RADS can be called anything...

    RADS Theoretical Ratio

    As Jack stated, the RADS is a Z-rig. If a person on the ground pulls the climber up it is a 2:1 to the person on the ground. If the person on the ground hands the pull rope off to the climber, it becomes a 3:1 to the climber. Unless a pulley system falls in the 'simple' pulley category...

    Hey Dave! The release in the vid is for a recreational version. It's not that rec climbers don't need height too, but the pole a lot of the rec climbers are using, I don't believe are safe for Big Shot pull forces. Hence, I have a housing designed and partly fabricated for a true Big Shot...

    [ QUOTE ] I've given the pistol grip/trigger idea considerable thought and scribble time. Yours solves (nicely, I might add) the problem of having the trigger on the under side of the pole and the release on the top side. You make your version semi-affordable, and I'm a buyer. [/ QUOTE ]...
