OK that could be misconstrued! I have a name (Alistair) and the GOD was an exclamation of exasperation! Im clearly not an extraction god.............or a ninja
But you are a God of Extraction now Alistair, where as I am a God of Insertion :Wideyed: My name: Vlad the Impaler
There is a major difference between a Grabit bolt extractor and an Eaziout - seriously, if you'd tried using a cheap (ie £10) Eaziout chances are you would have ended up with two broken bits of metal jammed in there instead of just one. Eaziouts are for removing bolts that have broken due to over tightening, not ones that are seized due to corrosion... Or - just a thought - had someone stuck it in with thread-lock ?
Nope. Just a bit of corrosion on the thread. It was like this when I got it..... I've got a big tub of copper slip for this sort of thing!
Yes but he said Extractor or Easyout, hence the comments - as he was wrong in view of a lowly 34 years of engineering experience and building bikes, that's all :smile:
I used a bolt extractor to remove a titanium bolt from a timing chain adjuster last year that was seized through bimetallic corrosion rather than over tightening. Worked a charm once I had finally drilled deep enough using HSS bolts. Took longer to drill than to extract. But there are a lot of people on here that have more experience than me. I'm a means-to-an-end type of chap. I don't care for the method as long as it ends up removed.
Most of the friction is likely under the bolt head. Drill the head off heat the calliper with a heat gun until it's HOT way too hot to touch smoking but not blistering get a GOOD pair of mole grips and really bite hard with then. Work the bolt up and down. There's an old saying in engineering if it wont loosen tighten it first, worked many times for me. Or if you'r chicken, try the impact to tighten. you just need it to move a fraction. Also heating HOT and dumping in WD40 or similar may help do it a few times and let it cool for 5 min submerged.
