Uni-bushes.....

[Random_guy]

Ok, managed to shoot one of my X7's up the rear end of another one tonight, the shaft itself appears to be fine, but the uni-bush is trashed. My coach reconed you can replace the uni-bushes somehow, but was unsure if they are hot-melted into the shaft or super-glued......

Soooooo

a) is it possible to do
b) how do you do it
c) where on earth can you buy a uni-bush?!

Thanks in advance for any tid-bits of wisdom!

[Tarkwin]

a - yes
b - see this doc p27
c - here is one supplier...

I'm having to do that very thing quite a lot at the moment - the perils of improving accuracy.

Some unibushing sizes are unique to X7s and must be specially ordered. My 1914s are such a size.

Easton's instructions say to superglue them in, but I find that the superglue sometimes sets too quickly to seat the unibushing properly, so they jam in place about half a mil from where they should be. I've had better results with hot-melt.

Yeah, I've had similar problems using superglue and now only ever use hot-melt.

I've replaced a fair few and always used hotmelt to put them back in. They are glued in place with some sort of black glue that breaks down when heated over a flame. You'll (almost certainly) trash your fletchings getting it out so I tend to remove those first.

Make sure you order the correct type of uni-bushings as well. I've ordered uni-bushings before when I actually needed super uni-bushings.

Good luck getting your bushings. Trashed two of mine two weeks ago and all my usual suppliers (including Alt) don't have them in stock. I didn't think it would be that hard to get busgings for 2114 xx75

The Easton Tuning Guide (downloadable from their website) says to use 24hr flexible epoxy for carbon shafts, or hot melt for aluminium/aluminium-carbon shafts. The technique is to heat the glue stick and apply a thin ring of hot melt to the inside of the shaft, then stick the unibush onto the sharpened end of a wooden pencil and heat it gently (if the pencil chars it is too hot). Then apply hotmelt tot he unibush and push it into the shaft with the pencil. They say not to heat the shaft itself.
They also say that some flexible 'instant glues' can be used bu the bush needs to be pushed intot he shaft very quickly in order to prevent the glue from setting before the bush is fully in.
