once it's pounded down that far, you're probably likely to never get it back out again. most all steel frames are reamed to their specified diameter only a relatively short distance down the seat tube, hence if you put a 440mm thomson or such into a frame, with only 80mm of it showing, you had better ream the seat tube deeper, or simply cut the post shorter. this can be done by any professional mechanic that posses the proper tools.

The tool you are describing is know as a "slide hammer".

can you use a hand hacksaw or a file to make a complete
slit down the old seatpost to help cut it out?



if you can hammer it down into the seat tube, is there a way to hammer
it up and out?

I'd imagine constructing a tool to hook onto the bottom of the seatpost
then come up and out of the frame so you have a part to hammer.

So I have a steel frame with a steel
seat post stuck in it. I did my research and tried all recommended
methods. I eventually hack sawed the top off and cut a slit in the seat
post and rolled part of it in on itself and it still wouldn't budge. At
that point I decided just to hammer it into the frame. Now my question
is it safe to use an old seat post to hammer the stuck seat post down
farther into the frame so that I can just put a new one on top of it?
The only thing I see wrong with that is added weight but maybe I'm
missing something...Any insight beyond my own teenage brain would be
appreciated.



Thanks,



Chris Robinson
