I just had returned to me a Gottlieb Queen of Diamonds that a year ago was just perfect. I loaned it to a museum and they had left it on so long a that the spinning bakelite disc in the head warped and scraped the backglass.... Totally disappointed.
I need to flatten it out but because its a mix of the two materials and has snow shoes on it i can't just press it between glass. I need to bake it until its warm and try to flatten it with separate pieces of glass or books.....
What temperature should I heat it to, and for how long?
Any help would be great........
