If anyone here has an extra coarse-tooth hacksaw blade lying around that I could borrow/buy i'd be interested. Trying to cut a seatpost out of an old frame and what better way to spend my winter hours right? Thanks for the help!

dump some 3-in-1 or other lubricant around the seam and put a radial sander on whatever is exposed, it might wiggle it loose, worked on mine anyway.

I'm already commited to the cut, this guy is SEIZED, still looking for a blade, I'd buy one myself, but I assume they come in packs of 3 or something, and I only need it for one job, i don't even have a hacksaw. Just trying to pinch some pennies, and i've already got too much random stuff lying around that I bought just for one job.

Alex Brooks might be the guy to talk to... he had a similar situation a while back.

dude... don't use a sawzall....it will sawz all, including your frame

the problem with aluminum seatposts, if you get them wet they will oxidize and expand - creating a very small layer of aluminum oxide, but a very strong force pushing outwards. this used to happen to quill stems a lot. the only way to fix it is to saw down the length of the post, once you get all the way through and the cross section looks like a 'c' it will come out with no force at all.

you can take one of my old hacksaw blades but I would just get a new blade. it will be worth it to buy a new, sharp one - it will take you half the time. wrap one end with string or tape or leather and watch a couple movies while you work at it. eventually you'll be successful...

james you should go ahead and buy yourself a pack of blades and a hacksaw to use them with. You'll need one someday and will be glad you purchased one way back when you had to get that damn seatpost out. An over-abundance of tools is never a bad thing... except on this website.

Did you try alternating ice and a torch? If the post and frame are different metals the difference in expansion/contraction can sometimes be enough to free it.

Nope, steel on rust on steel. It's like a chocolate oreo, except much harder to twist apart, and not as tasty. I think i'm just gonna buy the hacksaw blade and a twelve pack and get to grinding. Thanks for all the feedback, to anyone that's done this already, did you make 1, 2, 3 or 4 cuts? I was told 4 cuts to be sure, but has anyone here tried any lesser cuts with easy success?
