I feel your pain. I held the main turret component of a 1/25 Tamiya Centurion up too high and too close to a halogen bulb while I was working on the other end. I had to scratchbuild the entire section, including the add on parts. Hot water will help with alignment, but you will have some carving to do to get it back into shape.

 

Good luck.

Sincerely,

Mark

I do not have to tell you this, obviously, but you have to be very careful to keep thin wall styrene away from heat.

I learned that at another's expense back in the early 1960's when I saw a Revell Battleship Missouri kit that was assembled, carefully painted and placed proudly in the hobby shop window. Unfortunately, the window faced the sun during the hottest part of the day and there was no protective tinted clear plastic inner window. So the silly thing just curled up into a snake, with 16 inch guns pointing every which way, because of the heat from the sun.

So I learned my lesson from the hobby shop owner's error.

I'm sorry that you had to learn it the hard way.

 

By the same token, when storing kits keep them away from sources of heat!!! I have seen guys storing their kits atop steam radiators, next to hot air ducts, up against a sunlit window, etc.

 

I have heard guys bitterly complaining how their vacuform kits do not fit together because they were warped. Then when I ask where were they were stored, and, well, there is the reason. Vacuform kits have very thin walls, do not store them next to a heat source of any type.

YIKES!!!

I cant put any laughing or LOL type smiley faces here however....................as I know your pain ALL TOO well Ads...........

 

Had my P-51 resting comfortably near (but not VERY near) a space heater........and unbeknownst to me, while it was masked up for painting, and drying, it fell down and came to rest with her tail right near the heater. Needless to say I ended up with a HUGE mess:

TRIED to fix the melted part and ended up with a LARGER mess...............

Had no choice but to cut the entire tail section off..................................Only 1 fix on this that I could see, and its the one I implemented. Got a doner Has P-51, hacked the tail completely off way forward of where I needed to be, squared things off on a REAL flat surface, put in some plastistructs internal braces to keep things straight and aligned and Frankensteined the whole thing together. You can see in the last pic the difference in color between the two kits.

The fit ended up being not too bad at all if I do say so myself. In the end you would be hard pressed to ever know it was a wholly different tail off of an entirely different kit.

 

 

HTH,

Cheers,

Brian

We could probably do an ongoing thread regarding disasters. Not too long ago, I was trying to quickly force cure some modelling clay. Item was placed and sculpted on a 12x12 mirror, heat applied with my heat gun (on high setting), and mirror shattered into a hundred pieces. As to a fix for your boo boo, that's what putty is good for.

oh man!

 

This reminded me of that 'superdiorama' called 'legacies' (bob letterman?) - anyway it was about 5 square feet & I recall Verlinden productions moved premises years ago - the removal guys left the entire thing in blazing sunshine for hours & it melted! :BANGHEAD2:

 

anyhoo, I think you should be OK using the hot water retrieval method and a tonne of milliput - good luck!@
