Help with a Bent Smoke Stack

Hi -
For what it is worth, and I do not offer this as expert edvice, I'd be careful - I remember as a child trying to 'mend' various die-cast models and, almost without fail, the metal would break and crumble like cheshire cheese. It depends what metal has been used - some alloys are more ductile than others. If you are going to try to bend the smokestack back into shape, I'd find a metal rod which fits as close to exactly inside it as possible as gently use this to bend it into shape. If you manage to get some heat on all the better - some of these alloys have very low melting points and may soften at boiling-water temperatures (which shouldn't harm the paintwork). Or you could use the tip of a hot soldering iron perhaps to gently ease it upright?
But do not act on any of this until some others have thrown their oar in - just offering advice based on some experiences many years ago.

***Definately use a snugly fitted rod as advised. This distrubutes force and prevents local cracking. Definately use heat - the FLM metal will take a lot of heat compared to whitemetal so a total immersion in boiling water will not hurt the model - but MAY damage paintwork or lettering. Local heat could be applied with a heat gun or hair dryer set to hot and used close.

I'd not use a soldering Iron as the "rod" (tip damage will happen) or as heat as it will be a little too local as a heat source.

Take it slowly and if you can get a little movement, then reheat and apply it will be better than trying in one go.

Note: the very acction of bending will have weakened the casting at the base of the chimney so the result may be a fracture no matter what you do. If thats the case, clean up the base, clean up the stack and epoxy them, if possible using a sleeve or short rod as reinforcement.

Nicest option: Get a new stack from Wienart, cut off the original and replace it.

Thanks for the advice Richard and Mike

All taken on board , I will try the heat gun , I will try to get the screw out first as it will be in the way of the Rod
