Hey Howard, It was very nearly a Pyrrhic victory... but it goes in the books as a win. I ended up using 8 lbs of powdered lye, which translated into about 4 gallons or so of mixed liquid to dissolve the aluminum seatpost after I hacksawed it about an inch over the seat tube. I can't recommend the process. If you have any other means available do that first. It took about 4-5 hours and in the end I still had to use a hammer and screwdriver/chisel to get the last of the post out. Definitely a testament to steel frames as this one took a walloping. I was expecting a much more catastrophic chemical reaction but it was fairly sublte... I'll post a pic of the remnants of the offending seatpost tomorrow or Sunday. It was really amazing that even w/ 80% of the material dissolved the corrosion was strong enough to require the hammer/chisel approach for the last bit.
Back to the coffee, it was such a nice interlude in the week that I'm planning another one for next week. Thinking Tuesday at the same spot - LBJ Memorial Grove. Any takers?
