can't get the bolt off my ski pole grip

post #1 of 22
Thread Starter 

i have a pair of salomon kaloo poles and i was going to swap the grips for some bike grips but i could not for the life of me get the screw on the top of the grips off! the straps seem to go through the side of the grips and the screw goes threw it, but iv twisted and twisted and the screw wont come out. iv tried to pull the grip off with the screw in, and it wont move. i tried the door method and also heated them.

Typically the screw is there to hold in the straps, and the grip is just jammed on.  The grip will come off the pole with the screw still in.

 

I dip the grip into boiling water for a short time to soften and that tends to do the trick.  Same thing (sometimes) in reverse, to get them back on.

 

Good luck.

hmmm.... not seeming to work

If it's a metal pole, maybe put the pole in ice to make it shrink while you heat the grip.  I had to resort to packing the stub of a broken pole with crushed ice once.

i could try that but i was thinking maybe a hair dryer would work?

Can you put a length of pipe in a vise and pull it out through the pipe?  You'd have to take the basket off, but they seem to come off easier than grips anyway.

 

Last resort - cut them off.  THat's what you do with golf grips; slice them off with a box cutter.

that tube idea might work, i will try to find some tube to do it. heat is NOT getting them off. i cant cut them off because they are hard plastic.

I've heard of people sticking the grip into a door jam (above the door), closing the door on the pole and then hanging their weight off the pole.

If the grip is not coming off after soaking a few minutes in boiling water and then securing the grip with something solid while you pull, and you can't get the screw out, I'd like to suggest that you cut them off.  But I'm afraid you would hurt yourself.

sounds like it might damage the poles but ill try anything

cant cut the grips because they are hard plastic and iv done that with the heat

How hard are you pulling?   Some will take 150-200 pounds of pull to take off, even when heated.

iv pulled as hard as i could by holding it and pulled as hard as i could in the door so i think i need more leverage

yea, heat up in boiling water, then definitely you need some kind of puller to pry with your body against it.  door jam is the common suggestion, but I couldn't get a good angle on it, and it seemed it would ruin my door.

If you have a benchvise, you can easily set that up to have a gap that you can then pull gainst.

For me, I had folding ladder, and set it up so and closed the ladder legs onto the pole, then I could legpress the ladder frame and use leg power to pull the pole out of the grip with arms just holding on.

 

Required me to use a bucket of boiling water, and I had to reheat a couple times.

 

If you;re really stuck, I suppose you can use this same technique, and cut a notch in a solid board (exactly pole diameter, but smaller than grip diameter, that you can slip the pole into that board, then legpress against that.

i think that will be my next attempt. vise, here i come!

Yeah, pulling while holding  isn't going to work unless you're a master longbow archer or something.    You need to be able to apply force comparable to a large fraction of your body weight. 

 

 

If you really get desperate, you can try to work one of those plastic thin nozzles on a silicone spray can in between the grip and the aluminum.    Rubbing alcohol and ammonia spray can also be used as lubes.

do you think wd40 would work?

post #18 of 22

wouldn't hurt. but for my poles, i definitely needed to get the legs involved to help out.  Arms couldn't do it by themselves, especially since they're also doing work to just grip

WD40 is mostly Stoddard solvent and will melt styrene  - for unknown plastic next to aluminum, silicone, ammonia and alcohols are best.

I'm actually wondering if ice water would work better.  Heat softens the plastic so that you, in effect, don't have to get the whole thing to let go at once.  But I bet the pole expands more than the grip, which works against you.

Alternating between immersion in very hot and very cold buckets might cause enough microscopic motion to break the adhesion or the suction.

 

I know that for stubborn baskets, a big adjustable wrench set to just go over the pole diameter makes a good helper that you can stand on.  An analogy might work here.  If you have a vice, wrap something protective (scrap rubber for example) around the pole and secure it in the vice.  Put the adjustable wrench over the pole against the rim of the grip.  Tap with a hammer on the wrench.

I'll take that bet :).      The TCOE of plastics does vary, but you will have trouble finding an injection moldable plastic that has less than three times the thermal expansion rate  of aluminum.      PE and PP - anywhere from 10 times to 6 times.   Nylon - 5 to 4 times.   ABS - 4 times.    PVC does pretty well, better than some epoxies, 2.8 times.

Yup, +1 on this.  It's ridiculous how much black HDPE piping will expand in the summer sun, especially if you install it during the winter.

 

Snapple, sounds like those old grips might have been epoxied on or something similar.  You might be SOL - they're just poles, you know.  $25 or so...
