dbb Posted October 5, 2006 Share Posted October 5, 2006 I had a request for how I did this so I figured I'd write it up. How to make your own leashless umbilical cords similar to the grivel double spring: http://www.alpinedave.com/leashless_rig.htm Quote Link to comment Share on other sites More sharing options...
DanielHarro Posted October 6, 2006 Share Posted October 6, 2006 Thanks Dave, good info!! I just might have to make these since the ones from Grivel are $50.00 Quote Link to comment Share on other sites More sharing options...
Ade Posted October 20, 2006 Share Posted October 20, 2006 My design was similar. Quote Link to comment Share on other sites More sharing options...
dbconlin Posted October 23, 2006 Share Posted October 23, 2006 I have a question: why is it important to have a shock-cord/stretch leash? Why not just use some thin accessory cord? Quote Link to comment Share on other sites More sharing options...
Ade Posted October 23, 2006 Share Posted October 23, 2006 The shock cord means you have less leash dangling around getting tangled on things. You could just use some lengths of accessory cord but it would have to be longer than the shock corded leashes. Quote Link to comment Share on other sites More sharing options...
wdietsch Posted October 23, 2006 Share Posted October 23, 2006 Dave ... on your site you mention the use of the lighter weight "military/hikers" tape-webbing. I'm curious ... for a non-load bearing set-up why not do away with the webbing all together and just use shock cord. Perhaps not as durable but less pieces/parts/labor, etc...

dbb Posted October 23, 2006 Author Share Posted October 23, 2006 not a bad idea... I think a good reason is that the bunched up webbing actually keeps it from getting caught on your screws/cams/slings, etc. Accessory cord (or just shock cord) tends to easily wrap its self into that stuff.. Ade- nice! did you ever get viper strikes on the quark? I looked at one and it didn't fit. I suppose you could drill into the shaft...

lI1|1! Posted October 23, 2006 Share Posted October 23, 2006 My design was similar. so basically you're saying leashless umbilicals are ade? Quote Link to comment Share on other sites More sharing options...
scheissami Posted October 23, 2006 Share Posted October 23, 2006 Along the same lines, does anybody know if the "Trigger" made by Grivel will fit the Quark? It comes in two sizes.... Quote Link to comment Share on other sites More sharing options...
Farrgo Posted October 24, 2006 Share Posted October 24, 2006 The bigger one will, I forgot the color (black perhaps). Of course Grivel sells those for $25 a piece. I got a hose clamp and a pipe holder from the hardware store and made the same deal for $3. I just covered it up with rubber splicing tape and voila, I saved myself $47 duckets.

I have a Grivel Trigger I picked up last year, just before all the ice melted I should put it on. The Strikes didn't look like they'd fit.

Farrgo Posted October 24, 2006 Share Posted October 24, 2006 Here's the tool after its all finished This is what the trigger looks like. Only the screw part of the hose clamp is exposed after taping. It's important to put a couple layers of tape beneath the hose clamp as well or else you can damage the soft rubber on the Quarks grip.

Farrgo Posted October 24, 2006 Share Posted October 24, 2006 I'm a little confused about the umbilical. Why does the webbing bunch if its equal parts webbing and shock cord? How do you attach your tool to the umbilical? With a biner? Doesn't this get annoying as it smashes around with every swing? Quote Link to comment Share on other sites More sharing options...
Figger_Eight Posted October 24, 2006 Share Posted October 24, 2006 It's equal parts webbing and "stretched" shock cord. When the shock cord springs back, the webbing will accordion. Quote Link to comment Share on other sites More sharing options...
dbb Posted October 24, 2006 Author Share Posted October 24, 2006 F.E. is right. you strech the shock cord before you tie it. And I tie my tools on with shoe-lace type cord so I don't have carabiners banging around with every swing.. Quote Link to comment Share on other sites More sharing options...

I have a Grivel Trigger I picked up last year, just before all the ice melted I should put it on. The Strikes didn't look like they'd fit. The viper strike doesn't fit the quark but a visit to your local bike shop will do the trick. FYI grivel triggers: depending on where you place the trigger on a quark will decide which size trigger you need. Speaking of if you have the newer style trigger and cut the trigger portion off and mount the remaining piece backwards this will also work as an upper hand position/same thing the strike does.

OlympicMtnBoy Posted October 24, 2006 Share Posted October 24, 2006 I made some umbilicals about like this last year and they worked pretty good. I neglected to put in a swivel which I'll do this year as they can get twisted up if you're not paying attention and you match and switch tools a lot. I attached them to my tools with keychain biners. It worked alright and didn't bang around, until I fell while drytooling and left a tool jammed in a crack. Actually the biner held, although in a quite mangled state. I'm not sure exactly what the desired outcome is at that point (leave your tool on the route or have it zinging back towards you).

I'm not sure exactly what the desired outcome is at that point (leave your tool on the route or have it zinging back towards you). That is a part of why the grivel spring thing costs so much... though they use keychain sized biners the biners are rated to 3 kNs so that in situations like what you just described you don't have to worry about destroying a biner and loosing your tool (which sucks). A swivel on any attachment system is key though... But yeah... you can make them for a lot cheaper like a lot of you have but for me the spring thing was worth it.

kurthicks Posted October 24, 2006 Share Posted October 24, 2006 Along the same lines, does anybody know if the "Trigger" made by Grivel will fit the Quark? It comes in two sizes.... I have the yellow one on my quarks. it will fit on the rubberized handle (as a trigger) and on the shaft (for matching on). pick your poison depending on the type of climbing intended.

cj001f Posted August 20, 2007 Share Posted August 20, 2007 Hmmm. Anyone have a chip climbing swivel for sale? Rip the double spring Sorry - sold out! Unfortunately since Andy Kirkpatrick's rather spiffing review of this leash, demand has rocketed and caught Grivel unawares... However we have sadly just learned (23/7/07) that Grivel have decided that the Double Spring Leash iis economically unviable and the do not intend to make any more. We have written to them to try and persuade them otherwise... Quote Link to comment Share on other sites More sharing options...
