Have watched Facebook videos of people using hammer drills, on the hammer setting, with a modified bit with a socket on the end to vibrate seized nuts or Then this frees the nut/bolt to be unscrewed.

Hence the idea that forcing the seat post to move down will break the corrosion so I can remove the seat post by twisting or pulling.

I liked the idea, but in my head it said impact drive with modified socket to latch onto a bar drilled through the post (with pulling leverage from the bar with rope), if it's a 1/2" mechanic's impact driver then it may stress the seat cluster but it's all a game of risk

Have tried something similar with a stem stuck in a fork and a 12v wheel bolt gun and bolt remover. Just twisted the forks.

Be afraid to damage the frame.
