Finally got that seized seatpost out after three days of trying

It was a steel frame road bike from the 80s, the post was aluminum and totally stuck. I tried the usual tricks like ammonia and a bench vise, but nothing moved. Ended up making a homemade slide hammer from an old axle and a big socket, and it popped free on the fifth hard pull. What's your last resort method for a really stuck post?

Nice. Just a heads up, ammonia doesn't really do much for aluminum stuck in steel. You want a penetrating oil or a caustic soda mix. Slide hammer was the right call though.

Caustic soda can get pretty nasty if you're not careful.
