Rope Bridge for Master Classic

I'm looking to add a rope bridge to my Buckingham Master Classic saddle. I am planning on using Samson Warp Speed in either the 9mm or 11mm. This is the same rope that is used on the Buckingham Glide saddles and I have not heard of any problems with them. I'd like to tie the rope bridge to the loops that are on either side of the saddle near the leg straps. I'm researching knots to use to tie the ends of the rope to the webbing loops on the saddle. So far I'm looking at: bunt line hitch, scaffold hitch, anchor hitch, fisherman's, bowline. Does this sound like a good set up? Any other suggestions for rope or knots?

Thanks Everyone!
 
use a double fishermans(scaffold) they are the same thing. what means of attachment are you using? id consider using small quick links that are rated above 5,000 breaking strength. use one of the pre existing holes on the saddle that is there for clipping a carabiner into and put the screw links in. tie your rope bridge down on to the links and adjust to the length you want. then after you get it all set get some loctite and lock the threads down on the screw links. there you go :) good luck.

these are the screw links. the 1/4 inch ones are small enough to not be a problem with bulkiness on your saddle.

remember the loctite!
 
Thanks for the suggestions. I'd like to try and eliminate as much hardware as I can, so I probably wouldn't use the delta links or the clevis shackles mentioned in the previous thread. I could see how the thimbles could be helpful, but are they necessary? The webbing loops are about 1" wide, so it seems like the loops would be really squished inside a thimble made for a 1/2" rope. A poster on the other thread mentioned Ultra Tech, I wonder if that would be better than Warp Speed?

rope on webbing just like rope on rope will wear much faster then plastic on webbing which is why you should use thimbles. they weight and cost almost nothing...use em.
 
I use a rope bridge on my buckingham pinnacle. I just tie it on using velocity and bowlines with yosemite tie offs. The knot maintains a bit of an open loop so the webbing isn't compressed in the eye. In my opinion, the movement between the rope and webbing is so minimal that wear isn't a big concern. I've changed the bridge four times and inspected the inside of the webbing loops each time and the wear was virtually non-existent.

ultra tech is a bad idea becuase it has self abrading aramid fibers. heat resistant prussik cords tend to self abraid and fail. i think i remember Blinky and someone else talking about this.
polyester or nylon is the only materials a rope bridge should be made out of.
 
Interesting GORD, I'm sure your way is fine, but wouln't it be neater and streamlined to have thimbles and scafold knots? just my take not putting your way down as you have proven it works.

Absolutely not! Warpspeed is the way to go.
DO NOT use ultra Tech for a bridge. The inner fibers will 'self abrade' into fine particles and look like beach sand.

Gord, is that the "regular" pinnacle or the "deluxe" pinnacle, which I believe has webbing loops on the inside of the thick webbing which attatches the 2 front dees to the saddle. I have the regular which I love except I would like to try a rope bridge.

Can you post a pic of your set up?
 
It's the deluxe with the inside webbing loops, which is what I have my bridge attached to. I cut off the steel dees.

I don't know about the safety of using scaffold knots with thimbles. We all know that the scaffold knot cinches down under load, my concern it that the lowest turn on the knot could be spread out far enough by the thimble in a shock load scenario that it capsizes the knot. I did have it set up that way once, but after looking at it I decided to go with my gut, remove the thimble and switch to the yosemite bowline.
 
Cut off the steel dees? Radical move, which answers my question about what the dees are doing now that you have a rope bridge.

So with that alteration away from a standard Pinnacle setup, how do you like the saddle overall?

And a picture would still be cool, if you have the time!
 
I think I figured out my set up. I chose to go with Velocity for the bridge. I've heard that's what is used on the Ergovation and I've also read about other posters who use it as a bridge too. I originally planned on Warp Speed and although it has a higher tensile strength, I didn't like the idea that I couldn't inspect the rope underneath the the cover. Velocity doesn't have that problem. I also only put on about 120 hours a year and I plan to change the bridge every year.

I'll be using scaffold knots with thimbles around the webbing loops on the master classic. I also ordered a small steel ring to float on the bridge.

I'll post pics and let everyone know how it works once I get it all together.

Thanks for the info!
 
Are the gold Petzl gated rings big enough to capture the red webbing loops?? Not sure if the opening is big enough.
That's how I'm thinking of doing it...
 
All I can say is, don't use anchor hitches. I did on my master classic and found one had pretty much inched out in a very exciting way about 40' or 50' up.

Get a Butterfly II, you won't regret it.
 
I plan on dipping the ends of the rope in that liquid rubber stuff. That should help prevent the knot from backing out. If I notice any movement of the knots, I may end up stitching something with whipping string sort of like the treemotion bridge or adding some kind of stopper like those heavy black bands that they use for spliced ends of rope.

I have heard a lot of good things about the butterfly II. Whenever I consider buying a new harness I will look into it more.
 
When it was time for me to add a bridge to my master classic, I ordered the replacement bridge for the BF II. It works out great. I could not be happier.
