I need to get a bolt with a snapped head removed from my swingarm that also has the tip of an EZ-Out snapped off inside it. Great - I know!
So, does anyone know a good engineering place or person who can get the fecker out as I don't have the necessary tools!?
Cheers

Get a small masonry bit and sharpen the fucker up with a grinder, and drill the easyout out. Wear safety glasses plz kthx.

A dirty trick that tends to be 90% sucessful is to tig weld another bolt to the one withthe snapped off head. The thermal shocking seems to loosen it and you can (carefully) wind the rooted bolt out.
The trouble with all this drilling etc is if you run off center it is easy to damage the thread and create new problems
Take the bike to w welding shop or panel shop that has a MIG welder and capable operator.
Get a nut that is say 1 size bigger than the bolt...ie 10mm bolt, get a 12 mm nut.
Hold the nut in the welder earth lead clamp up against the broken end of the bolt
MIG weld the nut to the end of the stud and leave to cool.
The heat often helps to loosen the thread.
Be careful of burning rubber bushes
Disconnect battery before beginning process...if possible, un plug ECU
May need to repeat several times as weld may break several times....it can be hard to get a good strong small quick weld.

Oh yes plus one on this method. Used it before very sucessfully.......

Bit late now of course but I have a stash of left hand flute drills in my toolbox in common sizes. I always try them firt. Then the ezy out. Then the magic electric glue gun

You get something in the eye Steve? You're hard out on the safety goggles now :laugh:

Has there ever been an instance in the history of spannering where an ezy-out has been easy or got something out? I mean something that wouldn't have come out almost be itself anyway.

I know a few good engineers based in Welly. Give Garry at Metalworx Engineering in Vivian Street a bell & tell him Chris says Hi.

An ezyout isn't about extracting broken off bolts or studs, regardless of what the packet says. It's actually a way of removing the remanants of a thread without damaging the hole its threaded into. If you don't sufficiently drill the broken bolt out, then the threads left in there don't get sufficiently weakened, and thus the ezyout snaps instead of winding them out. Bottom line, always always drill the broken bit out as much as you possibly can.

Great - I know!If you have plenty of spare time, attack the ezy out with a hardened pick. Keep picking away at it, and it'll start breaking it down into tiny chunks you can remove. Does not alway work, but it's free to try.

Actually, I snapped 2 bolts in the crash! The first one came out without hassles with the EZ-outs. I just couldn't drill much of the bolt out which is why it snapped

Cheers for all the replies! I don't own a MIG welder let alone TIG! I'll have another go at it tonight, but failing that I'll give Metalworx a call

I mean something that wouldn't have come out almost be itself anyway. depends on the type of ezyout, the spiral tapered ones are not worth a cunt full of cold snow as as they go in they expand the hole, the quality ones are fluted parrallel to the shaft like a long torque head tool and I have pretty good success with this
otherwise some of the other methods are great best of course is spark erosion, not cheap but pretty well infallable

I always wear safety glass if there is any chance if crap in my eyes. It's like drinking too much and ending up with your face against the ceramic.. after a while you just won't do it any more. :no:

If that's the case, take the dollar hit and go see an optometrist. Be a shit of a place to get an infection.

Be a shit of a place to get an infection.Thats what I'm sayin' - an ounce of prevention.... it's not worth it any more.. and when there is hard steel on hard steel - doubly so. In this case, easyout meets rotating sharpened masonry bit - doesn't bear thinking about does it. :shutup:

Well? Didja get it out?
The bolt is out! Nice chap called John Mines TIG welded a bolt onto the end and was able to get it out. It really wasn't seized at all - just didn't snap off cleanly so I had hassles drilling out dead centre which is why I think the ez-out snapped. Also the first few threads of the bolt had stretched before it sheared which didn't help.
Anyway - done now, thank god!
Cheers for all the help

snap-on make the best screw-extractors. we remove heaps of titanium screws with 3/16" diameter thread - mostly as the titanium tends to break out when using hi-grip tips - it's actually quite soft but heat/work hardens in a flash when trying to drill it
