Stuck seatpost problems.
First of all, many thanks to all very knowledgeable users who through their posts have provided me with many good tips and advice.
Now on to my problem, a stuck aluminium seatpost (27,2 mm Dura-Ace) in a carbon frame. The seatpost is inserted about 14 cm in the frame.
When problem was first encountered I never imagined the headaches this would cause. I first tried twisting/pulling with all the power I could come up with. Tried to use saddle for leverage, only resulting in top bit rotating in the post (press fitted clamp bit).
By this stage I was getting frustrated and moved on to chemicals, etc. Some of which I should probably have avoided due to CF (WD40, lubricating oil, Coca Cola and ammonia). These where all applied through waterbottle bolthole using a "pipette" but without success.
I then had to bite the bullet and sacrifice the nice post, which I have been cutting/filing for about two weeks. I can't believe how tough this post is. The outer shiny layer will not break and I do not want to risk the frame, any advice?
Would say about 50% of post material has been removed, problem with hacksaw blades is to make the cut equally deep all the way down. Post has been cut/filed down in places 3/4 around the post.
Atleast I am a stubborn bastard and in the worst case scenario I will end up filing it all out, will probably take another couple of weeks.
Already at this stage I have ended up with LOADS of filings in the seattube which I plan to remove by turning frame upside down/hoovering out. Could this have damaged my Dura-Ace BB (BC 1,37 68)? Will this have to be removed and cleaned/replaced?
If/when post is removed it will be replaced with carbon post (carbon in carbon), what is the best to do regarding grease/copper paste? I never want to have to experience this again.
Any advice will be greatly appreciated, I can't wait to get back on the roads.
