seized setscrew

[Rubce]

Evening All

I need to remove the front brake disc dust shields as they are damaged. They are secured by a single setscrew which runs through the lower part of the strut/hub assembly. One of the shields came off after use of PLusgas, lots of heat and brute force loosed the setscrew.

However, the setscrew on the other strut just will not shift. I don't believe I am able to apply sufficient heat with my blowlamp. Have any of you tried either of the following two ideas?

a) place the assembly on the gas hob of the cooker and leave on there to cook until a nice cheery red. Remove, apply Plusgas and then attempt to remove the setscrew.

b) using a drill bit, hollow out thebottom 1/2 inch section of the setscrew which has the thread on it. I believe that this will weaken it thereby allowing the setscrew to move when subjected to heat and force.

Suggestions, comments welcome.

Regards

Yes, you don't want it a grumpy red :P

Nope. I have just purchased one off e-bay so will give that a go later in the week. Should I attempt to use when the setscrew is hot or cold?

Mine came off OK without any heat, worst that can happen is that it will snap.

I don't know about you, but if I put car parts on the cooker SWMBO would not be a happy bunny ! If you do get it cherry red, I wouldn't put plus-gas anywhere near it. Martin.

SWMBO can't complain as she is often hinting that I don't do enough of the cooking

Think I may try that tack next time, but better have 1st Aid help on standby!

Success

The stubborn setscrew is out and the entire front & rear suspension is now officially dismantled and bare metalled ready for painting to commence this coming weekend.
