idiotic bolt question

    So.

    I have a seized end-can bolt on the 'blade, and the allan-key hole is
    rounded off.

    I've tried hack-sawing a slot in it and using an impact driver, but
    still no joy.

    So, what's the next option?

    I've seen mention of people "drilling out" seized fasteners, but
    what's actually the score with this?

    Try the point of a cold-chisel in the end of the slot you've sawn,
    hammering along the circumference of the bolt head, anti-clockwise
    obviously. It's worked for me before.

    LH drill bit. It just works.

    that's something to try - definitely.

    The problem is that it's the bolt underneath the can, towards the
    swing-arm, so it's a twat to get at; ideally I'd turn the bike upside
    down for easy access[1]

    humour me - *what*?

    I don't have a drill that goes backwards, for a start.

    Well that's the next tool on the list then. Once you've got one you'll
    also need a LH drill bit, of course, and it should ideally be somewhat
    narrower than the bolt you're drilling. Then yes, simply drill down
    the centre of the bolt. As it starts to enter the bolt it will apply
    loads on undoing torque to it, as well, if it gets that far, as
    thinning the middle of the bolt such that it will no longer be as
    tight in the hole[1].

    Never done it myself, mind...

    I could facilitate this en route to move the Beastly Blade, perhaps.

    Even better, I could drop TOG's stuff off too.

    I can see a plan forming.

    Just don't break the fucking drill bit off in the hole, or you'll never get
    it out.

    <g> The other option is to drill a normal hole down the centre and use
    an extractor such as an Easy Out. I've also had success with this
    method. Of course you need to have a set of extractors to hand, and if
    the bolt has well and truly welded itself in there is the possibility
    of snapping the extractor, making any subsequent efforts even harder.

    me too, though somewhere along the line it needs to include getting
    the 'blade an MOT, as the prospective buyer is somewhat squeamish
    about taking it without one[1]

    [1] to be fair, understandably.

    Ah, that's good, because I forgot that this weekend is our annual
    Morris side's tour of Kent & Sussex[1] and I'm dancing all weekend so
    can't pick up until the weekend after...

    [1] Something like 15 pubs in the weekend

    Gas axe and application of heat then tack weld a suitable bar on the end
    (Unless it's stainless) and apply mole grips. If still stuck the drill
    through it, remove excess threads etc and re tap hole if space allows.

    All the equipment for this operation is in my mobile workshop sitting in my
    drive.

    A mixed side.

    In fact, so many women that I doubt the blokes could have made a side by
    theirselves.

    Discuss.

    Well get it round here & remove this stuck bolt from my Corvette then -
    the one in an alloy casting, with nothing left sticking out the hole, &
    a snapped off tap down the middle :-/
