Removing a seized seatpost
The seatpost on my Allez is well and truly seized-I took it to my LBS and they could do nothing with it. I have tried all the different approaches except for sticking it in a bench vice- unfortunately I don't know anyone who has one (although to be honest I don't think it will make much of a difference anyway). The heating/freezing approach doesn't work because both post and tube are aluminium so expand and contract together. I've tried penetrating fluid (loads of it) and every other suggestion I can find, so it looks like I am going to have to sacrifice the post so that leads on to my questions-
What is the best way to cut the post so that it can be removed (ie how many cuts and in what direction?)
What is the best thing to use? I have hacksaws etc but someone did mention a Dremel with a metal cutting bit. My big fear is cutting down to the seat tube and being unable to cut enough of the post still in the frame to remove it.
Simply put I don't want a cut seat post that still won't come out!
Any suggestions as to cutting (or any radical new approaches I may not have tried yet) would be more than welcome.
