Is your axle slipping in the hub?
I've got pictures of removing the axle from a Profile hub in my
'Dissected Profile Hub gallery'
(http://gallery.unicyclist.com/Profile_hub). The process would be very
similar for a KH hub.
I used 'JB Weld epoxy' (http://www.jbweld.com/) to secure the axle in
the hub. When Unicycle.com fixes the KH hubs they use 'Loctite 660
Quick Metal retaining compound' (http://tinyurl.com/6qhyk). In both
cases it is important to clean the parts before using the Loctite or
epoxy. With the Loctite you should also use Loctite Primer which is an
acetone based solvent that also accelerates the bonding and gives you a
stronger bond.
I would suggest using the Loctite 660 first. The Loctite will be much
less permanent than the epoxy. With the Loctite, if the axle starts
slipping again you'll be able to undo it, remove the axle and reapply
the Loctite or switch to the epoxy. With the epoxy you're stuck cause
once it is dry you are not going to be able to ever remove the axle
again.
Since you're in Australia, you could find out if Unicycle.com NZ can do
the repair if you don't feel up to it.
