I am likely not the best resource for removing stuck parts. But I have tried Acetone/ATF with good results on a 50th Paramount, and paint damage on an Terry from the lye process. The lye caused a $200 paint job so I don't favor the process. When destructive processes occur I am a big fan of using a pin through the post with a socket specially made to fit over the post and am impact wrench. After that a slicing through the seat pillar with a long blade using a Saws-All and pulling the pillar apart bit by bit from within the tube. Lye is my least favorite method. Smiles, MH
