Patience is the best practice for the challenging
corrosions ...
My latest battle was approx one month battle to remove a seized seat post that was stuck in metal frame seat tube.
AL Nitto seatpost.
Start using PB Blaster spending one week applying to post from bottom bracket and from top of seat tube.
Flipping frame and using rubber mallet to hit / twist seat tube from top.
Next using KRoil spending one week applying to post from bottom bracket and from top of seat tube.
Flipping frame and using rubber mallet to hit / twist seat tube from top.
Next using CRC Freeze-off spending one week applying to post from bottom bracket and from top of seat tube.
Flipping frame and using rubber mallet to hit / twist seat tube from top.
Next cut off top of seat post and drilled holes on both side to insert long screw to be used with longer metal poles.
Used this to gain max torque for twisting seat tube.
After many attempts to twist off over one day and adding more penetrating lubricant between attempts, the post finally twisted free.
Victory !
