You sure that's oxalic acid B?

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

X2 - you'll be there longer than 2019 using OA.

Tis my mistake

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

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?

animal · « **Reply #10 on:** December 19, 2011, 07:28 PM »

should have dissolved easy by now

I got daves out his GT in 4 days

stfc · « **Reply #11 on:** December 19, 2011, 10:18 PM »

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 ...

Darren KAP · « **Reply #12 on:** December 19, 2011, 10:25 PM »

I used a air saw on one of Digglers frames , took abit of time but came out in the end

i did it for free as he offered me man sex for payment

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

skyway67 · « **Reply #14 on:** January 04, 2012, 11:18 PM »

how much of the seat post do you reckons left in the frame ?

theres a good chance i could drill this out for you

BENDYCAT ELEVENTEEN · « **Reply #15 on:** January 05, 2012, 12:37 AM »

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

skyway67 · « **Reply #17 on:** January 05, 2012, 07:19 PM »

no problem just that i have my own engineering machine shop and work for myself

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

i can also make wheel spacers brake parts crank washers etc

and cylinder heads are a speciality

BENDYCAT ELEVENTEEN · « **Reply #18 on:** January 05, 2012, 08:43 PM »

now you fricking say Daz

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

skyway67 · « **Reply #19 on:** January 05, 2012, 08:56 PM »

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

well you know where i am if you get stuck B

BENDYCAT ELEVENTEEN · « **Reply #21 on:** January 05, 2012, 11:47 PM »

true

so where abouts are you in the country

we might have to talk

skyway67 · « **Reply #22 on:** January 06, 2012, 08:21 PM »

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 ?

BENDYCAT ELEVENTEEN · « **Reply #23 on:** January 06, 2012, 09:06 PM »

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

skyway67 · « **Reply #24 on:** January 06, 2012, 09:37 PM »

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
