[Closed] Where can i buy ammonia?

Get really de-hydrated and wee on it. Not sure how easy it is to buy pure ammonia with it being an ingredient for lots of explosives.
You can buy solutions (as cleaning products) from hardware stores.

as a fetiliser from a farm shop? I know NO3 is used as a fertiliser. actually... we made ammonia in school just the other day!

Walla24, you can bet with that post something went 'click' on the computer programs of one of the security services!.

PML @West Kipper

You can buy it online normally in 500ml bottle from various places. I bought some for the same reason but it didnt work or maybe I didnt leave long enough. Just make sure you have all the windows open and cover your eyes and nose when using it. Just search for household ammonia.

are you building a bomb ?? (secretly)

No need to laugh ,Cullen.
As we've all taken part in this thread, we'll probably ALL be named as co-conspirators at the trial.
Anybody got Aamer Anwars phone number? 😐

Quite popular for use among gangs etc or was..
ie Bernard o mahoney used it alot..

Some poor GCHQ chappie or chappess will now be obliged to wade through hours of STW shite to confirm that we are not in fact international terrorists hell-bent on the destruction of the Western world, but are in fact silly middle-aged blokes who ride bicycles in mud..

But if they read the actual mag and see the amount of bushy beards that are featuring, we might be in trouble.

Time to shave!

Middle aged blokes

Speak for yourself...... 😉

Anyone know where I can get any detonators ??

Don't know what I'll do with them, but it'll keep the secret service busy anyways...... Maybe I'll get a late night/early morning knock on the door 😉

Would you like some Chapati flour to go with that sir?

Ammonia? Detonators? Beards?

GCHQ have just changed their light bulb from yellow to red.

When I left school had a job as I dyeline printer, for an oil exploration firm full of sandal wearing long bearded geologists (probably rode SS) used a rotary printing machine that used Ammonia to develop the image onto paper or sepia, place used to really pen & ink. Doubt they still use that methoid now. Could try a printers.

"As judge, I direct the jury to disregard the defendant(s) claim to be naively researching seatpost removal, and find them instead, GUILTY of attempting to cause explosions, and conspiring with the full intention of committing acts of terrorism"
I'm tellin' you I can see it now...

Ammonia is horrible horrible stuff to use and anything that you can buy for household use won't be anywhere near strong enough for what you need.

What's the frame? Steel or alu?
A mate got his seized seatpost out with very strong caustic soda solution but it took about 10 days of him changing the solution every day. That was in a steel frame; he stripped it down completely and poured the caustic in from the BB shell down the seat tube.

has anyone said mohammad jihad yet?

Just nipping down to the woods to film myself crawling in the undergrowth with a tea towel on me head and a [s]toy gun[/s] seatpost achem!

Yup, publically available ammonia is nowhere near concentrated enough, I've tried the very same trick.

I've also had the same funny looks when asking in B&Q for drain cleaner that specifically contains H2SO4, NOT the usual cheapy one that contains alkalis lol (Home anodising!)

Hmm! I bought a kheffiyeh (sp) scarf in Jordan last year, and we have some Arab head dress type things from Egypt.

Very incriminating if I get a knock at the door.

Give them something to read anyway.

i dont no if this will work for you but coca cola work for me turned bike upside down and soaked seat post for about 6 hours.

Heh heh, Idlejon, at least the rest of us are gonna get a loaded trial.
you're not even going to get that, Its straight to Guantanamo for you!
D'ya suit orange? 🙂

You dont want to use coke, its A) sticky and B) acid, it creates more metal oxides. If it would come out with coke it would come out with wd40 (by which I mean it's purely the soaking thats helping moisten things, which WD would do just fine).

aluminium oxide is amphoteric so it will react with both acids and bases. You best bet will be to try a dilute hydrogen chloride solution.

but before you try mucking about with chemicals have you tried the brute force technique of removing most of the bits off the frame. Put seat in bench vise and rotating the frame around the seatpost using all the lovely leverage you get by hauling (carefully)on the headtube. (the trick is gradually apply the pressure, not maul it and it should release easily as it rotates.)It's not as brutal as you first think and has never failed yet.

Homebase sells it. Use it to cycle fish tanks instead of using "suicide" fish!

Do you want to be able to use the seatpost again?
If not, crush it in a bench vice near the bottom. Rotate 90degrees and do it again.

aluminium oxide is amphoteric so it will react with both acids and bases

That's quite odd though, as Al2O3 (anodised surfaces, which as far as I'm aware are the same as normal oxidation products) strip quite nicely in fairly weak alkalis but are perfectly happy in very concentrated h2sO4?

wo...wo.... enough of the bomb jokes people i dont fancy being dragged off by men in suits!

yes i have tried many other brute force methods as you describe...

does crushing the seatpost work? there is only about 6cm of its length exposed?

its aluminum frame and alu post.
The post is already ahem broken....the seat clamp is no longer with us.

so whats the best ideas:

amonia
hydrogen chloride
crushing
(also tried the drill through + rod +spinning)

beer to whom ever picks the winner! this is annoying beyond belief!

Clamp the seat post in a vice & twist the bike..whats the worst that can happen?

I tried the grab and twist solution, it didn't solve it on mine, it just started bending the frame. I cut the top off the post, sawed down the length of the inside of the post with a hacksaw blade (took sodding forever as you can put very little force on it, but I have a pierced seat tube so I could re-attach the saw handle, radially out from the centre, making sure not to go into the frame, then crushed it with mole grips. It fractured into about 5 pieces but I managed to "roll" one edge inside the rest of the post, at which point the bonded joint failed spectacularly and all was good.

I've done what coffeeking suggests (as a last resort) on a BMX frame.
I used a large hacksaw blade that I 'backed' with a thin piece of wood. Took bloody ages to do though, and I'd use extreme care considering the frame is alu too.
(sorry about the unhelpful OT jokes BTW) 😳

yep done the vice thing, no grip first off so drilled hole put bar through to give the vice something to grip....bent the bar, had a couple ppl swinging on it.

coffeeking isnt there a large risk that i will just crunch off the top and leave the rest in the frame?

There's a small risk, yes. But you're ****ed anyway at this rate, at least with the top cut off you could get it reamed. I meant make a cut down the length of the inside of the post, in case that wasn't clear. Once the cut is made you can slowly work round and force the post in on itself.

that is true.
someone would be able to ream it yeah, just need a big drill?

bit confused how to cut sorry, do you know of any diagrams/photos to explain?
cheers

Most MoD establishments are on th elook out for bike frames left for a while as they make pretty decent pipe bombs, just in case you think going back to the frame problem get you out of the sniper's sights

[i]its aluminum frame and alu post.[/i]

You're f***ed then, chemical methods aren't going to work.
Using base (NOT acid) would work for steel or ti frame/alu post but not for alu/alu.

If you really don't want to damage the frame, send it off to Argos or similar, I think they guarantee to remove any seized components.

Acid FTW...

plugas might be worth a try

walla - best way I can describe is imagine your seatpost is a banana and you're going to make a banana split, but from the inside. I hack the top off the post (a a few inches up), then use the blade inside the post but along its length. If you're very careful you can do it without putting a slice in your frame, but if you do put a slice in your frame it is pretty much finished, so err on the side of caution!

crazylegs- who are Argos? not the supermarket chain im guessing?

haze- what acid was that? and how did you go about it?

coffeeking- yep i get that thank you, on the look out for a long/low profile saw!

thank you all for the ideas, keep em coming along with any success stories!

Don't bother with the ammonia. I got some from work (our lab) and it was nice and strong. Did nothing to the seatpost, just made my eyes water and took my breath away!!

Only thing is to get the hack saw blade out and take your time cutting the post out. Takes a good while though so get something good on TV and enjoy!!!

Been there, done it. About 3 hours and your done!!

ok looks like thats what il be doing, where aboutss can i get a hack saw thats that small mind? as it has to actually fit inside the seatpost?

I just used a normal sized one. Post was 26.8mm outside dia and a normal one fitted inside that. Just put gaffa tape on one end (stops the teeth digging in your hand) and get cutting. Change blade on a regular basis though to make it easier. Best when they're nice and sharp!!

ahhhhh.....so use the blade not the handle, got it.
righty-ho will get on that later.
cheers

Yes, just the blade!!

Good luck!!
