Hello all

Really could use a little advice / tips on how to get a broken spoke out of my back wheel.
A few broken but there is one which is stopping play - it has snapped clean off at the rim and left nothing projecting. SO just the nipple and a short stub of spoke left which is inside and fluch with the rim.
My local wheelbuilder broke into a sweat trying to push it through with his tap and I have damaged the rim a little trying myself.

I was thinking applying some heat to the rim to help get things moving - anyone know if the rim anodising will discolour with a heat gun?

Any help gladly received! :beerjug:

Well, I've got hard anodised aluminium pans that are still just the same colour after a few years use. Whether the same will apply to a wheel rim is anyone's guess but I'd risk it.

That said, given the state our your rim after your spoke breaking incident, I'd have said a little discolouration is the least of your problems :D

Heat and plusgas would be my approach - the alloy rim will expand more than the spoke nipple and may just relax the fit enough for you to tap it out with a parallel pin punch.
 
aye i think i am just going to go for it.
The rim can just look after itself i reckon - got to get that broken swine out to use the wheel again anyway so (gulp) i think the heat gun will be out tonight... :eek:

fingers crossed I dont kill the rim
 
They are barstewards as Steptoe knows.
I did a short thread somewhere about my experiences last year.
You cannot tap them out because you cannot get purchase or bash in the right direction.
I would carefully drill the head off, then tap inward ! Taking great care with the rim. Or get professional help.
 
I have one missing at present. Seized one in the wheel. Drilled the head off and still can't get the old one out. Patience and Plusgas is the way forward for me.
Still using the bike though.
And the BMW service manual states you can only change one spoke then the wheel is done anyway.

ah haaaa - well i got one out just by bending the end over and mole gripping it / rotating to break the bond - eventually it came out!

BUT the other is stuck, so technically i guess with a new one back in and the missing one, well, missing, it should be ok to drag SWMBO and luggage around the coast of the entire UK next month ( :eek: ) - best not tell her though :D
 
DONE IT.

p1ss easy dont know what i was worrying about! :D

Forget trying to drive a flush spoke through from inside to out - get a little patience and a decent 1.5mm metal drill bit, drill off the head (increasing drill size slowly to 4mm) and the head just pings out.
Follow up with 4mm parallel punch straight into the resulting hole (self guides so no worries on alignment) - out it pops!

Took ten minutes after p1ssing around for an hour trying to go the other way...

happy cat. No damage to outside of rim neither (unlike the inside :()

Photos on way if a friend can help again ???
