Not fused about paint. I'm going for caustic. A hacksaw blade only just reaches towards the bottom of the post and even with a torch, I can't see how well my cutting is going lower down the shaft.
I've cleared some space in the shed so I can apply the potion outside, wait for it to settle down and then lock it in the shed out of the way while it bubbles slowly away all day. Then, in the evening when home from work, reapply as many times as possible before bed, where it can again soak overnight.
Hopefully, given a few days of this process I'll be somewhere close. Will try to pull/chip bits away once some of the material has left. As I've prised the top part of the post away from the tube, I'm hoping it can get down the inside an eat some of the galvanic corrosion that is causing the problem. May be wishful thinking.
