Ice Tools: Upgrading Quarks with Trigrest piece

[Skirotica]

So I picked up a used set of quarks (pre 2009). They have the heel rest but don't feature the trigger rest found on the latest version. Well, that was a major priority for me so I bought the trig rest upgrade (http://www.petzl.com/en/outdoor/vert...ories/trigrest) and went to work installing them.

I've found that they don't install on the shaft above the rubber grip. And when they do install on the rubber grip, I can't get them tight enough to ensure they won't slip. They're supposed to be adjustable, which I assume to be, flip up the trigger and move them up and down. Doesn't seem to be an option given the ergonomic shape of the handle and the width of the shaft right at the grip. I've installed them two different ways to see which I like better. I'm ok without the trigger, I really just want the rest at about the half-way point, but then I worry about the integrity of the add-on if I leave the trigger off (seems to get in the way in the setup I've photographed). Note, when the trigger is on the shaft above the rubber grip, I can't flip it down. I've tried, but get worried I'll break it before it flips. Seems the trigger has a nice lip on it where it connects at the bolt. That lip is meant to create a tight fit, but it offsets the holes and I can't run the bolt through anywhere on the metal shaft.

Has anyone else made this upgrade and resolved the issue in another way?

KISS - "keep it simple stupid" is the philosophy I fall back on. One because I am stupid (hehe) and two because I don't like a lot of moving parts. Shit breaks and I don't like when shit breaks while on the sharp end.
I like the second hand position this add on gives you but don't see the need or desire for the finger trigger - this is my personal opinion.
As far as trying to get them to fit the handle or shaft for an older model tool (clearly the new design must be thicker?) you might try this: cut a bicycle inter-tube and place it between the two parts. Light weight and will not slip. Worked for me on my old pair of Petzl Axars - I modified them with both the heel and trigger rest and still going from old school to new school without forking out big $$$ for new.
Try it? You might post this on NE Ice or NE Climbs too? Not sure how many ice freaks lurk here?

Thanks lynch. did actually post it on NEICE.com first. Went for TGR because I worried no one was looking on the other these days.

The innertube could definitely be a solution. Alternative is to cut the trigger off at the base and just keep the base there for integrity. A clean cut and i might be able to make it look like it was meant to be that way.

I have big hands so the trigger on the rubber (e.g., tool sitting on the left) is awesome bare handed but not so great with a pair of thick winter gloves on. I'll probably wait till next season when I can do a little experimenting on a top rope before deciding on a permanent setup.

Well first off it doesn't fit because it wasn't designed for the older quarks. The best modifications were using the old grivel triggers. Thats what I would suggest if you really desire your second hand position.

My thought is why add the trigger rest? I used simple grip tape on mine and it was adaquate for the all the climbing I've done with it (AI2-WI5+). As you probably know, it creates a sticky surface with out bulk, weight or extra object sticking out when wielding the tool. Just my two cents...
