Making a bark saver w/rope without splicing 3 Years, 8 Months ago  
After hanging one of my homemade bark savers (and my climbing line) this morning on a not very tight crotch I think I need a redesign. My current device is a length of 11mm rope with a double noose knot (aka fishermans knot) on each end. I'm using 'biners instead of rings. Installs fine, works great but one of the slip knots hung the tail end of the saver on a small but very tenacious bit of bark in the crotch when I was taking it down. Removable by rethrowing a line and pulling the rope back through the crotch in the other direction but a pain in the butt.

I'm thinking that I could make a continuous loop similar to a footloop out of 11mm rope, using the double fishermans knot as shown in Jepson's to close the loop. Then tape the knots to make them more smooth for going through the crotch, and make them more secure. For ring attachment either tape or whip wrap the ends to create a tight loop for the biners (or rings).

So bearing in mind that I don't want to spend money right now on a ready-made false crotch and I have no splicing skill at the moment ... Any ideas on how to make a bark saver with rope without splicing? Does the design I proposed have any obvious flaws?

Thanks!

You're on the right track. But any way that you make a false crotch with knots will leave a glob that can hang up.

A cheap way to make one that is neater is to get a sewn webbing loop made from one inch tubular webbing from a mountaineering shop. YOu might find 5/8" Spectra loops too. You can either tape or hand sew a tight eye on the webbing to capture the large biner. I move the sewn splice close to that end so that the sewn eye is just a little ways from the splice. Then you can either sew or tape another eye on the other end. Be sure to sew or tape the webbing flat too. Since the sewing you're doing doesn't have any support needs you don't need to be concerned with strength. Using a speedy stitcher or sewing machine is fine. You could probably get a shoe repair shop to sew it for a couple of bucks.

New Tribe makes false crotches out of webbing. Their eyes are large but I'll bet they would sew them down for a slip fit on a biner. That keeps the biners from flopping around so much when you set/retrieve them.

The webbing FCs that I use are four feet miniumum.

braided false crotch design 3 Years, 8 Months ago  
Here's an alternative bark saver that I made last night:

Braided bark saver

It's made with two lengths of 11mm Blaze because I didn't have a long enough piece to do it with one. I made a shorter version with one length of rope.

It's tough as nails, probably overkill 'cause it's a little heavy. The length is 66" from loop-to-loop. There are no knots (well the whole thing is a knot). The loop to braid transition is nice and smooth so it should slide through a crotch pretty well.

There is a non-structural splice on one braid strand in the center of the saver. It's pretty secure since the braids create so much friction in the length of the saver. The strength of that section of the saver is 2x 11mm instead of 3x if a single length of rope was used.

Tom's suggestion to make a saver from webbing makes a lot of sense, I'll see what my local climbing store has to offer.

Moss,

That's sure a nice looking false crotch.

If I understand what you're saying, the ends of the ropes aren't spliced together. Is that right? you're relying on the friction of the braids to secure the whole works. This could have merit, but without some testing I'm leary. How do you secure the ends? Stitching the ends would add a lot. Putting in some stitching at regular intervals would be a good idea too.

Yes, theoretically there would be no splicing.. The end loops are a continuous part of the entire rope.

The ends of the rope are located and taped at the loops after being braided the entire length of the saver, so even with my bogus splice on one of 3 strands in the center of the saver the sucker is strong. The rope ends are hot cut at an angle so there's a smooth transition from the loop to the braid.

The weakest point is the single strand of rope at each end loop. I will test it low of course.

Cheap Savers 3 Years, 8 Months ago  
How about some old garden hose for a friction saver. Can that damage my rope.
I also am concerned about my "Fly". One of the product de_script_ions I read said that it is like a static kernmantel. Can it still be used dynamically for DdRT climbs?

You guys are a real help with this board by the way. Thanx Joe
