Assuming it's a cutting disk then the edge. Should go through a crank arm like it's cheese. Make sure there's nothing too flammable in the line of fire of the sparks.
Was just looking for a picture. Found a few unpleasant ones... be careful with it!

Edge into the top of the axle hole.
oh, so effectively cutting the crankbolt hole in half? Ah, I was grinding the whole "outside" back to the BB
^^^ that deserves a 🙄

I'd just cut the crank arm close to the axle on two sides so you can lever it apart and off the axle.
The steel axle's going to be a lot harder to cut.
Kryton- not quite, I mean here, from the top of the bike, not the side.

Once you're through to the axle the hole will open up and it should come off. No point cutting into the axle as it's much, much harder.
Ah well, new frame time.
The bit on the spider the arrow above points to is conical - narrow end in. Cant get the grinder near it, crank now a pile of crap attached to a frame - which I just slipped and took a chunk out of the chain stay.
Recommendations for frame and fork? 😥
Oh god.
Oh, phew, you did a stealth edit. I came in, saw this -
Ah well, new frame time.
And assumed you'd chopped your downtube.
Alternatively go into it like this, cheaper than a new frame-

wtf? Just looked at all this and kryton has slipped with an angle grinder and gone into the chain stays!?
yikes! just a scuff I hope. 😯
Still got yer fingers then ?
Good.
Frames are cheap compared to fingers and much easier to get hold of.
Heres a link you might find useful...

Oh shit,sorry to hear that Kryton,I thought you were on a roll with your new grinder skilz.
I now feel bad for putting the hex on you with that 'grinder/frame interface post' earlier. 🙁
I'm embarassesed to post this, but for the sake of any help, the mess:
see the nicks in the frame?

Giant Defy?
Just a thought, if you can't shift it & don't want a trip to the LBS why not try your local back street garage? They'll probably have a puller that will do the job or just smack it off.
If you're coming down this way I'll happily have a go.
Edit: looks salvageable.
So I reckon thats a ribble / planet x frame for winter thats cost me.
Doesn't look that bad.
Might get away with those nicks if they are chain-suck sort of deep.
is it a sticker?
That'll be fine I reckon. I'd ride it. Just keep an eye on it. If you're really worried, get a carbon fibre kit and wrap it.
Or duct tape 🙂
awww shit!! this thread seems to be coming to an abrupt end due to Kryton's cack-handedness with an angle grinder!
i was hoping it would have had the longevity of his Phall munching escapade! 😉
you should have continued bashing it off with a hammer...15 minutes? you werent even getting warmed up!!
But how do i get the crank off?
Here's e backup, seeing as I was going to go 105 and splash 850 on a tcx any way....

Get a drill! Surely it's a useful tool to have around the house anyway?
I've got a drill. What do I do with it? I do t have a bit big enough to drill out the spindle.
No, you just drill a series of holes into the crank (the part at the top of your pic) in a line(ish) so that there's hardly any metal holding it together. Then hit it or ride it a bit and it'll break/split and fall off.
4 or 5mm drill bit I reckon. Alu is soft so it won't take long to drill a few holes.
Seriously though, if you can secure (what's left of) the crank arm in a vice or something then use your chisel to **** the end of the axle with your biggest hammer I reckon it'll go - you just need to have someone/thing to hold or catch the frame when it does.
put somethign behind the crank arm so you can't cut the frame and carry on cutting.
if you held the blade parrellel to the ground as it is in that shot and cut into the arm just above the spindle you'd get through without hitting the frame.
good lord....
I think i will turn down your kind offer of the angle grinder kryton..;-)
Does anyone else feel this thread is rapidly becoming worthy of inclusion on the 100th edition cover?
Tpbiker I suspect the problem isn't so much the tools...
Hoo-****ing-ray...

Now, will my paranoia let me do a 100k without worrying about the frame snapping...
Bike upside down?
Oh dear.
EDIT just seen that Kryton trashed his frame then carried on. I almost feeling like retracting my comments above.

You don't have the BB out yet.....
Filthy Bike...
Filthy Boy...
At least you have your fingers left, you do don't you?
That frames fine, just keep an eye on it and cover the marks in black paint..
You
Are

One
Aren't you. 😀
anono - MemberDoes anyone else feel this thread is rapidly becoming worthy of inclusion on the 100th edition cover?
Yes. Most definitely!
If anyone ever asks again why we need LBSs ,show them this thread.
😀
Don't worry about the marks Kryton,no one cares about their winter bike 😉
Does this mean he needs ANOTHER THREAD to choose what to replace this with?
Well, the latter irony is that its all done, and I was able to turn the BB by hand and remove it. The 105 HT2 fits straight in nicely.
Here's the damage; Now I've stopped panicking all of the marks are white paint except for the middle on of the three on the left where you can see some alu.

I'd better place that Merlin order now I guess.
Oh, and I'll never by anything with square taper again...
Oh, and I'll never by anything with square taper again...
LOL, you chose not to use the right tools.
Classic "bad workman"...
Well to be fair, the puller stripped the threads, and I had turned it right in with a spanner...
Hmmm, can I trust the above. N+(N-1)1?
In that case you can kind of blame the tool (and I don't mean you) 😀
I'm happy to be the tool on this occasion. I'll never be letting an angle grinder near one of my bikes again either.
best thread for ages....had me in stiches.
ineptness at it's best...... ;o)
Hmm there's a Kinesis race light frame in the clasifieds in my size for £160. Maybe I should cut my losses and put the 105 on that, I've aleays like them.
But will it take guards...

Get.
