It took me about 2 hours to put 3 cuts through a chro-mo seat post that was wedged in a good 4" into the seat tube. I used a hacksaw blade that I'd slotted into a piece of 3/4" x 7" dowel,for extra purchase. A lot of work/patience but my only option once I'd been down the vice/lubricant/heat gun route.

i removed a mk1 burner post by first of all soaking in plus gas down the seat tube(also thriugh the bb if you can access it).i then drilled a 10mm hole through the post .i then inserted a bar through the hole so that there was no play.i then give the post a few taps from the top with hammer and then used the bar to turn the post out.i think i read this somewhere on here.this might not work all the time but it certainly worked for me.no caustic nor heat required.
