    OK, I have a question for you diecast pros, how do you, or can you straighten the door frame on this diecast 34 that I just picked up. Hope you can see in the pic that it has a twist in it and bent in towards the cab too much. And yes, the roof does/is removable. Don't really want to make it a coupester! Any info will be greatly appreciated.[​IMG]

    Zinc usually bends once, then when you try to bend it back, it snaps off.

    After it snaps off, you can epoxy it back where it's supposed to be, perhaps use some wire on the back side to give it a little more strength.

    IMG_8032.JPG I agree with squirrel.
    I have found that if you copper plate zinc components,
    like a horn ring, they can be soldered back in place., but is not super strong.
    Twisted parts would be really difficult. You could machine a duplicate piece
    out of 6061 aluminum as was done to make a duplicate of the original
    die cast zinc convertible top piece shown below but, it would be expensive.
    I am assuming your twisted piece bolts to the cowl.
    Any chance of posting a larger photo?

    I believe it's a die cast model.

    Bending diecast on toys can be hard. Heating it up and bending it very very slow sometimes works. If it breaks a good repair with some JB weld or other epoxy can save the day.

    When you bend metal it work hardens. If you want to bend it again , it will need to be annealed.

    If it's a model make a new piece out of plastic wood.

    You may be able if you're slow and careful.

    You might get some tips here:

    Yeah I thought it was to. I was looking for a die cast video on repairs and came across it. I thought it was weird enough to post. No offense.

    The videos were great. The one showed some of the things I am familiar with and I learned a new trick I want to try with the super glue and baking soda. The second video gave my Grandsons and I good laugh. I had showed them videos from this press guy before which we always enjoyed.
    Good luck with your project Rich S. I am sure you will get it figured out. I like working with diecast and have built some small scale replicas of my real cars that I have designed and built. Always a fun winter project.
