I’ve tried this and it was made of such flimsy metal all of the force went into destroying itself rather than getting the crank off. Eventually the top casting sheered in half.
The crank is still attached.
My conclusion was you won’t get it off without heat. Find an LBS that has a blow lamp and a GBFO hammer.

i've normally just taken the bolt out and ridden around for a bit, it'll just drop off.

I made an angled wedge to fit between the frame and the crank with a slot for the axle, this work\ed for me.
-
wondering if people have tried and had success with any particular model.
This pattern has always worked well for me on cranks, also does many headset crown races.

I need to pull off a crank from a bb where the crank extractor thread is toast. I'm thinking of getting some kind of cheap bearing puller from ebay but wondering if people have tried and had success with any particular model.
