/ Undoing the bolts on Quarks - help!
Not that I imagine they'll have changed, but my axes are the previous version to the ones currently on sale.
Any help appreciated!
Try soaking the heads in boiling water (or as hot as you can get).
Anti clockwise for undoing stuff unless its something like a wheel hub where the left had side one will be a left hand thread. don't concern yourself with that though, it'll most def be anti clockwise. Are these bolts or hex headed things? <allen key> If the latter I'd look at investing in or borrowing an impact driver, this is like a big thick screwdriver and you hit it with a hammer, the downward force of the hammer blow is turned through 90 deg to tighten or loosen stuff. The plus point of the impact driver is that the hammer blow will keep the hex headed bit deep within the bolts socket and reduce the risk of chewing up the hex socket in the bolt. If they chew up there is nothing to drill and drilling out is the only option. If you can't get access to an impact driver ask a garage or engineering shop to do it for you, it would only take a few seconds. If they are 6 sided bolt head don't use a ring spanner as these only grip the corners of the hex shape, not the flat. Use an open spanner that grips the flats or a socket set with flat gripping sockets. HTH
Use a piece of pipe to give you more leverage by slotting it over the alan key. I used an old ice screw to do this... but any pipe would do, so long as it doesn't bend.
Go to the Petzl website, download their maintenance dowmload pdf and it describes this there, if you've any doubt.
Make sure you use a good quality allen key as crap ones will round out the heads.
If they are Allen headed bolts and v.tight, a male torx socket lightly tapped in is usually more successful than an allen key at undoing without rounding things.
When in doubt....WD40 ;-)
Thanks for the suggestions all. I had already checked Petzl's advice, trying to increase the leverage on the Allen key seems to be the answer though will have to improvise without dedicated tools or a vice. I figured it was lefty loosey but wondered if any one knew any better! Will have another bash (literally!) tomorrow.
Incidentally, I wouldn't use (nor do I own!) a blow torch but wondered how heating would help loosen when surely it would cause the metal to expand? My limited knowledge of materials/physics would make me think that it would be better to cool it...
I think you're right.
The thermal expansion of aluminium is about twice that of steel so if you think friction against the aluminium head is stopping the bolt turning, then it would be well worth sticking the axe in the deep freeze so that the aluminium shrinks more than the nut/bolt.
The only possible problem with that is that istead of rounding the corners, the head of the bit can shear off and get stuck in the head of the bolt. Saw it happen on my cousins nomics. this resulted in a couple of hours trying to coax out the stuck bit before getting some decent allen keys.
I think decent allen keys and a vice are the best way, although with out a vice I'm not sure what I'd do
Nice vice advice.
Not a very good idea on highly stressed and safety critical heat treated steel. Judge it right and you loosen the bolts, judge it wrong and you change the temper of the picks.
I'd be happier adding an extension to the allen key, rather than holding it in a vice and using the axe as a lever - I think it would be much easier to ensure the allen key was in the right place and there would be less chance if anything slipping and rounding off
If you're struggling to find something to use as a lever on the allen key - you can use a ring spanner quite succesfully.
It's pretty obvious how to do it if you just have a play.
Definitely advise clamping the axe securely rather than the allen key as mentioned above.
If you haven't got a vice you can use a hard edged step, just stand on the key in stiff soled shoes and turn the axe.
If only I'd read that 10mins ago! Ah well, never mind...
Success! Soaked the bolts in DW40 and left the axes out in the cold conservatory overnight.
Then inserted the allen key so it was at the same angle as the pick, turned the axe on its head and put my foot on the allen key to hold it then applied brute force to the other end of the axe. Longer levers and a bit of lubrication was just enough to do the trick :)
Repeated six times, now I have one slightly sore foot and two shiny new picks!
Thanks for the advice and happy winter climbing all!
