HELP!

Fitted my fork gaiters tonight....done one side at a time, first fork went like a dream, off and on in ten minutes.

The other fork was a different story - went to undo the bolt on the lower yoke, hardly any pressure and half the bolt snapped off....

So I'm left with half the bolt still in the yoke...

Tried drilling it to get an easy out in there but the drill has barely marked it

any advice??

Ok I've sorted it - engineering workshop in my dads work are gonna sort it for me If I bring them the yoke

Had something similar... When removing the mudguard mounting screws, which are bolted into the fork legs, one of the heads snapped clean off, leaving the remains recessed beneath the hole. Drilled into it, with slow speeds, which is the secret to getting a good cut from the bit. In goes the easyout with the aid of the tap wrench. Bugger doesn't want to unscrew, so I give up, without risking snapping the easyout and leaving that in there, making an even bigger mess! So I move up to a bigger size drill bit and repeat. The remains are still seized in solid, even after much penetrating oil is applied. So in the end it was a case of drilling it through with the same size bit as the screw and then tapping a new thread, which did the trick. Took bloody ages though. Patience is the key with this stuff.

A lot of people have had success with cobalt drill bits, although in this case I just used whatever HSS bits were in the box. The penetrating oil seemed to help the bit to cut in as well.
