Hello all Not so much a question about cars but i figured some of you will probably know a thing or two about seized parts.
Basically ive got an old Pug racer bike and I'm trying to dismantle it so i can repaint the frame. However i cant get the quill stem out of the forks. Ive undone the screw out the top and tried hammering it but it only hammers flush with the top of the stem, thats if i don't miss and make a dint in my stem. Also tried letting it soak in wd40z and twisting it to free it up, none are working!
Anyone heard of Plusgas? Ive heard its good for seized parts, anything else i should try?
Cheers

Soaking stuff in petrol has never failed me. I've unseized old lawnmower engines by just bathing them in petrol before.

You've moved it by hammering it, and it twists, so it's not seized, just tight.
Have you tried heating it?

Yeah its the general section, but this is retro rides....for cars...not bikes. I'm not bothered in the slightest but someone will report this and it will get locked...

get the fork CROWN in a vice and swing away at the bars a few good thumps to the stem may help as long as its not alreary bottomed out. heat wont help here, something like coke or diesel poured into an upturned fork may help but due to the tolerances involved itll take some time to do anything much at all, the buildup of corrosion can add a lot of pressure + friction

Andyboy is right, this Forum is about cars...and even so, the technical section would have been a more appropriate place to ask. Seeing as you're from Grimsby, get in touch with Mike D and ask if you can borrow some of his Penis-oil* - I'm not joking either, it's the best stuff I've ever used for siezed bolts etc. There are plenty of Area 52 regulars that would say the same too. It's like plusgas. And then some. * Penis-oil is a registered slang term of Area 52 and not to be used wihout our written consent. However, you may use this term just the once to ask Mike if you can borrow some. Any further use of the term outside of Area 52 without our consent could result in a lifetime ban of the use of the word Penis, even if referring to your own or anyone elses.

Assuming you're dealing with an old pre-aheadset arrangement, I'm not sure how you could hammer it any further than flush? If you've wound the bolt far enough out and then hammered it down, it doesn't sound like the wedge is what's keeping it in place. This site seems to explain the operation nicely: www.bikeradar.com/road/gear/article/workshop-how-to-service-a-headset-22225/My apologies if I am actually teaching you to suck eggs here. ps. It's a general section not a general chat section. It's still only about cars. I'll move this thread to the reader's other mods section.

Seized Quill Stemretrowagen1234

I'm having the same problem with an old RHONSON AUTOCYCLE at the mo.. The stem itself is seized into the fork rather than the wedge keeping the quill flared.
Take the front wheel off, Flip the bike over and get a long rod. Hammer down the fork tube from the bottom... (try get the wedge out the bottom first or youll just be flaring the quill each time you hit it.

Loosen & remove the stem bolt, then cover the hole with some gaffer tape (or simular). The turn the frame upside and pour "DEOX C" by "Bilt Hamber"into the opening in the bottom of the forks until its full of deox C and then leave it for a few days I used this method on an old raleigh that someone had manage to flatten the bars with a hammer trying to remove them after a few days soaking I managed to twist them out by hand www.bilthamber.com/pro-introduction.php?cname=Corrosion%20Removal&name=deox-C

Take the front wheel off, Flip the bike over and get a long rod. Hammer down the fork tube from the bottom... (try get the wedge out the bottom first or youll just be flaring the quill each time you hit it. On better-quality frames the steerer tube is butted so you can't remove the wedge from underneath - so this might not work. Anyway, if it's moving with a hammer then you should be able to twist it with a long bar. If the frame is steel and the stem is aluminium, and if it's really stuck, then you can find a trough or container large enough to fit the forks in, upend the frame so it's resting on the forks, and pour a strong solution of caustic soda into the trough. This will eventually dissolve the aluminium (takes a few days) but won't harm the steel. I have removed a couple of stuck seatposts in this way - it does leave a hard white crystalline substance behind (any chemists?) which can be dissolved with ammonia.

Sorry about posting in the wrong section
As for penis oil I'm not sure about that haha! What actually is it?
Will ask my dad if he's got any petrol that isnt in a car for the lawnmower or something. As for the wedge I'm not sure if it actually moves I don't think it does, I'm not sure what happens with the bolt when it hammers flush but it doesn't seem to be messing up the thread on it so I'm not sure.
And I live near peoples park Foxy
Edit: thinking about it i might buy new forks and possible a new stem anyway so might just saw the curse word out of it ;D

Chemodex PenolUsed so regularly, and under the above mentioned phallic slang at Area 52, that nobody even smirks when it is said. It just is its name ;D

The bottom bracket shell is threaded so it will unscrew. You'll need a big-ass bar though, as the torque rating is unreal!

As you can see from the pic it just a round disc with only 2 flat parts so its pretty hard to get a grip on it, was twisting with pliers, the widest they would go :/
