hi. Just wanted to check if a heat gun on the lower nut n bolt holding the front strut to the brake hub is an acceptable substitute for a blow torch? Really dont have the funds to go out and buy a blow torch :-( but i do have an awesome heat gun :-)

[TheBoy]

Shouldn't need heat on that

[Lazydocker]

2nded... That shouldn't get that tight Get manly with it and it'll probably go

But in answer to your question... If you can concentrate the heat properly then yes, although I doubt it will be anywhere near as hot as you need

Correct sized socket plus big breaker bar, deep breath and heaveeeeeee

If all you want to do is heat up threadlock, then a heat gun might work, and a blowtorch will probably work.

If you're trying to shift a seized or damaged fastener(exhaust manifold nuts/bolts/studs are typical examples), then you'll need to get the entire fastener red hot. That will require oxy-acetylene welding gear. Anything else will be a waste of time/consumables.  And if you're going to use heat, use it before you damage/round off/snap the fastener using any other method.

ok thanks guys.... but seriously this aint coming out! lol

ill try and smack an undersized socket on to it first and then get evil with it!

ive got a gas torch if you need to borrow it,need to find it in the garage and i also have a big bertha gas bottle and torch,but i think that may just set the car alight lol

I can't quite picture in my head what it is you're trying to undo; but is there any chance that you're trying to turn it the wrong way because the head is facing away from you, if you see what I mean?

As a license is needed to store acetylene a good substitute for at home is propane, my boss has recently replaced the acetylene with propane to save money, although the flame is larger and it doesn't burn nearly as hot it does get the fastening more than hot enough to loosen them up.

heat gun is too diffuse, inefficient and slow heat transfer to heat conductive materials like steel,  , and not nearly hot enough ,   by the time it's put enough energy in,  it's already been conducted away ....   

you'd succeed in heating the planet before you got that hot enough with heat gun.

Agreed,about as much use as a chocolate fireguard

Have you got that nut off yet webmeister , if there as tight as my wheel nuts were you will be needing two 16 stone mechanics bouncing off the end of a breaker bar to get it off   --^--

[dbug]

Further to my post above - big hammer on breaker bar!!   . . .  or scaffold pole

Care to expand on that? Although there are regulations regarding how you store acetylene(or any other compressed gas for that matter),including how much, what's kept near it, and the actual cage it's kept in, I can find nothing about a licence. Plus the regulations state that they only apply to industrial applications.

I'm not convinced about using propane as, to me, the whole point of having the kit is that it's usable for welding, cutting and heating, all without the need for power.

I was told whilst in college a license is needed to store the acetylene but not to use it, as for using propane, the only reason the boss has changed to this is that it is cheaper and we do not use it for anything other than heating objects.
