Title: Rock hard nuts.....
Post by: Orange777 on July 12, 2012, 09:22 PM: I have an SR one piece stuck on a GT Power Disk that I bought from the US....

I cannot shift it with a giant spanner, I cannot shift it with blow torch heat, large spanner and vice

In fact its officially stuck! I even took a chisel to it today and it was hardened so the bugger would not move......

Where do you take these things? I am not even sure what tools someone could use...

All help appreciated!!

Post by: oldboyburner on July 12, 2012, 09:39 PM: Anti clockwise only mate keep at it in the vice
Title: Re: Rock hard nuts.....
Post by: Orange777 on July 12, 2012, 09:43 PM: Had a two man attempt, with the vice - anti clockwise with a blow torch........it won't shift!

Hammers, the lot........ does anyone ever glue these??
Title: Re: Rock hard nuts.....
Post by: bobbbbsy on July 12, 2012, 09:43 PM: id probably try a lump/club/mini sledge hammer on the spanner end or if all else fails the bike shop where they have loads of big park tools spanners and appropriate work bench!

Post by: oldschoolace on July 12, 2012, 09:47 PM: Apply some physics to the equation :daumenhoch: find a long steel tube that will fit over your spanner and the extra leverage should pop it off no problem ;)

Post by: Orange777 on July 12, 2012, 09:51 PM: The spanner I tried today is for a HGV, its about 3 foot long...... did nothing with two of us pushing it! :(

Thanks for Physics tip though - good call!

Christ :shocked: errrr... double the length quadruple the force.... or summat like that.
Try a longer lever :daumenhoch:
Title: Re: Rock hard nuts.....
Post by: Orange777 on July 12, 2012, 10:03 PM: Going to try the longer shaft method.

Failing that - not even sure where could take it to! Maybe a bus depot? Do we still have them in 2012?
Title: Re: Rock hard nuts.....
Post by: BENDYCAT ELEVENTEEN on July 12, 2012, 10:05 PM: have you tried turning it off and on again ???
Title: Re: Rock hard nuts.....
Post by: Orange777 on July 12, 2012, 10:09 PM: Not tried that yet Bendycat! Very shortly it's going to fly off a 4th floor balcony! :)

Post by: Orange777 on July 12, 2012, 10:14 PM: Thanks for suggestions. Will see what I can find locally. Engineers or bus depots. Have a feeling that in this quest of man vs. machine, machine wins! :(

Post by: oldschoolace on July 12, 2012, 10:16 PM: Never yet been bested with stuck nuts when i've used a long lever. The creak/ snap sound as it finally gives in to pure science is satisfaction guaranteed :daumenhoch:

volvo amazon wheel nut
Lambretta kick stand bolt
Datsun 100a exhaust mount bolt

and many others have all resisted wd40, blow torches, diesel, freezing and a few other methods but ALL have secummed to a mighty lever
>:D >:D >:D ;D

Post by: BENDYCAT ELEVENTEEN on July 12, 2012, 10:18 PM: pour some coke~a~cola on it and and if you can make it stay there, then the coke will loosen the rust which is locking it on ;)
Title: Re: Rock hard nuts.....
Post by: Orange777 on July 12, 2012, 10:28 PM: Old school ace you are the king of nuts!!

Thanks Bendycat - do you mean leave soaking in a coke bath?

Would overnight be long enough? Will get 4 litre of coke.

Cheers!!!! :)
