Removing stuck or seized seatpost?

this method could damage your frame though.

I wouldn't recommend this be done on a carbon or aluminium frame.

Only succeeded in tearing off the seat post. Gonna have to get me workmate and try hammering fcuk out of the post.

That must have been fairly stuck in there. Seeing as aluminum is much softer than steel I would very much doubt you could damage a steel frame with this method, as shown by the post above the seat post will simply break/tear if the corrosion bond cannot be broken. Unless of course the hammer makes contact with the frame.

@Beanpie, the problem now will be avoiding damage to the frame when you start hammering as it will need to be somehow stitting/clamped/both to something totally solid. Might be best to go with the caustic soda dissolving option.
