Could you not get it machined out? There was a guy on recently, a relatively new guy with a mid school GT and drilled the post completely out. He did it at work if I recall ???
-
have you tried caustic soda?

have you tried caustic soda?
X2 - you'll be there longer than 2019 using OA.
-
Tis my mistake ;D i have been using caustic soda on the seat post - the bubbling might be a bit of washing up liquid on the pipe brush i used last after giving it a good clean out of all the sludge - acid oxide was for the rust parts i have been doing ;)
it will come out soon i'm hoping :angel:

Looks like it's wide enough to fit a hacksaw blade down the inside of the post now. I'm sure people on here have got them out using that method. Might be worth a shot...
-
Would it be easier to just replace the whole tube?
-
should have dissolved easy by now :shocked: I got daves out his GT in 4 days ::)
-
have used before in no particular order ... Electric saw as used at any decent garage, 3 cuts down the sides 10 mins and out , Heat , Old stem down the seat post tighten up heat the post , twist etc 20 mins , diesel ... didnt work ... Good luck , on that I would go down the leccy hacksaw route ...
-
I used a air saw on one of Digglers frames , took abit of time but came out in the end :daumenhoch:
i did it for free as he offered me man sex for payment :shocked: ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, :LolLolLolLol: :LolLolLolLol:

while i was waiting for it to do it stuff it gave me a chance to try and find some lost bits - a year and a half later i found the packet i lost containing my DX end caps and the old set that were in the pedals - then i found a lost renthal post (used and needs work ) cheers for the one you sold me Daz ;)
I think the seat post is well seized all the way down and that is why it is not coming out well ::)
-
how much of the seat post do you reckons left in the frame ?
theres a good chance i could drill this out for you :daumenhoch:
-
It's got a hole in the side of the inside of the tube i can feel
I think that the thing is that is has welded all along the tube and not just a bit at the top - this is why it's taking it's time
it's getting more out each time i look at it
this is a build that i can work on as i still haven't got all the parts and the mags need doing - so i just work on one of the others while this is doing
thanks for the offer but it will come out in the end
i'm gonna need a good welded - seat tube has been cut at some point in the past and just need a new bit in it's place or weling adding to it to close up the parts ? any one ? a name ?
cheers B ;)

Sawzall or Animals the fellas for that BE :)

no problem just that i have my own engineering machine shop and work for myself :Great_Britain:
this is my skyway frame having the rust and muck honed out
i was struggling to get a seat post in............. the exact opposite to the trouble your having

;D now you fricking say Daz ;D
It's nice to see the pic's now to back up the talk ;)
i think you may have some pm's from members and just what you can do
do you do any welding ?
cheers B ;)
-
i can weld but i only have a basic mig welder
this seat mast of yours needs tig welding ideally
a very good friend of mine does any welding i need
he can weld steel, stainless steel cast iron bronze, copper ,brass and aluminium :daumenhoch:
well you know where i am if you get stuck B :smiley6600:
-
skyway67.....i think you've just become EVERYBODY'S new best friend. :LolLolLolLol:
-
:LolLolLolLol: true
so where abouts are you in the country
we might have to talk ;)
-
i'm in worcestershire near the safari park and severn valley railway
as i said earlier in your thread a post like aluminium would drill fairly easy ........... is it 22.2 mm ?
also the seat post damage looks straight forward as long as the metals good
would the frame be powdered after ? :)
-
Your about 2h48mins away from me so a courier it would be
yes it alloy - most likely 22.2
yup tube top has two cuts (not by me) and done back it the day i think - will just need a weld and then maybe another cut ?
yes being powdered up
there is one of the extra tubes that is missing a bit of welding ? and as it will be under powder, can your mate do that ? 1/4"
cheers B ;)
-
no problem
the seat post would have to be drilled out first
then the tube prepped and welded up and have the expansion slot machined in after :smiley6600:
