I recently spent $35 on an early 80's Univega with the infamous SR LaPrade fluted seatpost. It's stuck - REALLY stuck. The paint burned off around the seat cluster should have been a clue - live and learn, but at the price I paid, I probably would have taken the bet, anyway. I've worked my way through all of the suggested solutions, including alchemy, in Sheldon Brown's "15 ways" article - freon, PB blaster and ammonia have all failed, as has brute force in the vice and hammering on a pipe wrench. Sheldon's suggestion of using the saddle for leverage was a joke - I mangled the saddle with my bare hands in about 20 seconds. I'm right at the "last resort" point where I'm about to cut through the post and slice it into sections. Unfortunately, I spent some time reading the "screwed the pooch" thread from a few months ago on the C&V forum, and I expect I'll find a tube with 1/2" thick walls when I make the cut.
So, I'm wondering if anyone has some creative solutions for living with the post as is, or modifying it to make it work without getting it freed. The saddle needs to be about 1 1/2" higher. One thing that's occured to me, for instance, is that I could just cut the post and drill/tap into the two sections, and put a smaller-diameter hollow tube and supporting spacers in the middle. Anybody out there have experience with some other "live with it" solution to this problem?
