But, what to stick them back with ? The shop hasn't been totally helpful (suspect that adhesive technology might not be a strong point) and suggested things including PVA wood glue, Cynoacrylics (superglue), Epoxy resin (araldite). These are all somewhat different adhesives. I certainly wouldn't go for the Serious options like Araldite, because once that's on it'll never come off (not a problem if you're happy to throw away a grip if the pole busts, but good grips are worth keeping IME, just in case the replacement has been "improved"). Think I'd be inclined to use a glue-gun, since clearly the glue will soften at high temperatures, and those are unlikely to affect you while skiing... That's a hunch rather than hard knowledge, though.

Will go off and google the low temperature flexibility. - Nigel -- Nigel Cliffe, Webmaster at http://www.2mm.org.uk/ |

I am not sure where you could mail order furrule glue in the UK, but
here is a website from the colonies: http://store.yahoo.com/gear-west/exelglue.html If you check this web site you can at least get a image of what it looks like. (It looks like a can with glue). I bought a can of exel furrule glue 20 or so years ago and it does not take much to glue ski basket/furrules to the sticks. As mentioned, the glue that remains on the stick when removing and replacing baskets is usually adequate for the new basket. Ski shops that sell roller skis are likely to have a supply of furrule glue. If you cannot find a supplier in the UK (mail order or otherwise) it may be a good time to go on a ski holiday in Norway.

If the handle can be unbonded by heat (i.e. hot water), it is probably glued using ferrule cement or glue. Pole ferrule glue is applied by heating the glue and applying to the stick. Replace the grip, properly positioned, before it hardens as it cools. Same process for replacing backet/ferrules. A full service ski shop should have furrule glue. To remove, heat as you have been instructed, You do not need to add new glue except where you cut the glued section of the stick off. Edgar Why not hot melt glue used for crafts and various fixits? gr |

Edgar Why not hot melt glue used for crafts and various fixits? gr Good question re craft type hot melt glue. The answer will depend on the temperature needed to soften or unbond the glue. Ferrule glue for poles seems to unbond at a temperature below 100C (boiling point of water at normal pressure). The handles or baskets/ferrules can be unbonded by heating the pole in boiling water, or with care, by a hot air gun. At 100C, the heat does not seem to damage the plastic of the baskets or handle, or the resin of carbon fiber poles. So, the question is what temperature does craft glue need to be heated to to unbond the glue and will that temparture (heat input) damage a resin-fiber pole shaft, plastic ferrule/basket, or the grip? Of course, if you never need to redo the grip or ferrule, then any good waterpoof adhesive will work. Edgar |

To which the answer seems to be 170-200C for most hot-glues. There are some "low temperature" types, but they are around 120C. Ferrule glue for poles seems to unbond at a temperature below 100C (boiling point of water at normal pressure). The handles or baskets/ferrules can be unbonded by heating the pole in boiling water, Something I'd be keen to be able to do if required. The leather handle can go inside a high temperature plastic bag (grocery store for cooking purposes), and then be dumped in a pan of boiling water. The handle gets hot, but the leather doesn't get a soaking. air gun. At 100C, the heat does not seem to damage the plastic of the baskets or handle, or the resin of carbon fiber poles. So, the question is what temperature does craft glue need to be heated to to unbond the glue and will that temparture (heat input) damage a resin-fiber pole shaft, plastic ferrule/basket, or the grip? Ferule glue looks like the best idea on the table so far. Possibly its Shellac under a different name ? Its getting a bit late for googling here, but I'll look up Shellac properties another day. - Nigel -- Nigel Cliffe, Webmaster at http://www.2mm.org.uk/ |
