I'm in the process of re-doing a Street Fighter 2 pinball machine cabinet. Overall, the cabinet is not in bad shape, expect for the bottom. It looks like moisture sat in it for a while, and the bottom is sagging pretty badly. The bottom appears to be 1/2" MDF. As you can see from the picture, there is about a 1 inch sag. Saggy Bottom...

Ive never done a cabinet bottom before. If I have to remove it, I'd like to get it out more or less intact so I can use it for a template for making a new bottom. Beside the sag, the bottom is not in bad shape. Is there a way I could mold the MDF back into shape?

How did Gottlieb attached their cabinet bottoms? Are they in a groove like Williams machines? It does appear the it is glued in place around the outside edge, but I can't tell if it is in a groove.

Thanks,
Alan

Anyone?

I have the same issue with the weather. Im going to get all my wood working done, and wait for warmer weather. It's hard to paint when your shop is heated by a wood burning stove.
