I recently did some trading with member IB57 and ended up with an 81 Panda 24" BMX cruiser. I went to tear it down and ran into the dreaded seized up seat post. My first attempt involved a set of big Vice Grips and a big hammer. The seat post didn't budge a bit...and I was hitting HARD too. :shock: Next I started spraying some penetrating oil down the seat tube hoping it would loosen things up a bit. Tried the Vice Grips later on in the day and nothing. Did a bit of searching online and saw all kinds of approaches from using dry ice and a torch to some dangerous chemicals to cutting it out with a sawzall. Then I stumbled upon someone's suggestion of clamping a BMX stem around the seat post down near the seat tube and then attaching some forks onto the stem for leverage. Sure enough....tried that approach, took the frame out in the grass and set the frame on its rear drop outs, held onto the bike's forks and then stepped down on the fork/stem combo and it broke the bond immediately and after a little wiggling it slid right out.
