Right, I have the old stuck alloy post issue, so I have rather reluctantly began the potentially lethal task of dissolving it with caustic, trouble is this has been going on for the past five days and nights now with me out there pouring in the crystals, followed by a load of boiling water then hot footing it back indoors like i've just lit saddam hussains favourite firework he had hidden under his mattress, trouble is everytime I go back to inspect my handywork(sunglasses of course on) nothings happened, just a small amount of blackish slime, am I doing something wrong, do I need to invest in more potent chemicals, any advice would be much appreciated neighbours are getting suspicious ;)

I would dissolve the crystals in hot water first, then pour into the seat tube. i think you may have clogged the tube with crystals (which seems to set like stone)
Try getting a long screwdriver and bore a hole down it so the water has a better chance of dissolving the caustic.
Good luck :daumenhoch:
it is a slow job, try not to rush the process... slowly slowly catchy monkey ;)

Yeah, he's bang on. Make your mix, pour it in. Patience is needed.

cool, think you may have it there I will try the screwdriver tomorrow :daumenhoch:

U don't need a lot of crystals buddy ;) bit at a time fella :D I have done loads and it always works ;) Helps if it isn't done outside in the cold . I used a blow torch 2 reinvigorate the mixture . Plus every time u do a mix flush out all the gunk then start again :daumenhoch: murder that ally post fella :daumenhoch:

well funny this question has been ask as i'm doing the same boring thing - and guess the CS has gone solid inside
had a look today and it seem to of been sick, as it looks like a poltergeist has thrown up black stuff and it's drip down the frame and started to dry white - freaky stuff :shocked:
I can see the post has got smaller and just wonder if next year it will be ready to let go ;D

. I used a blow torch 2 reinvigorate the mixture .
:LolLolLolLol: a few deep breaths over the end of the hole just to check the mixture is working too ...... you should feel a slight burning sensation around the inner lung area :D
Good luck Fraz , it does work ;)
-
cheers , will keep at it then :daumenhoch: was about to give up and try to get it drilled out somewhere , hopefully won't have to ever use the sh1t again after this, chemicals and me is just not a good idea :LolLolLolLol:

caustic it again :daumenhoch:

Flush with warm (not Boiling Hot) water and as is says on the bottle.....
Rinse and repeat :daumenhoch:
Flush a few times sounds as if you have too much gunk/CS/debris down the seat tube.
