I have a 1985 Williams Sorcerer with a problem I've never seen addressed before. The bottom of the backbox has a very nasty crack in it that goes the entire width of the machine. This crack is causing the backbox to lean forward precariously; right now I have a piece of metal with two wood screws (one above, one below the crack) that's quite possibly the only thing keeping the backbox from cracking the rest of the way and crashing down onto the playfield box. The crack is as much as 2-3mm wide looking at it from the back of the machine.
Anyone have any advice about how to go about repairing this? My tentative plan of action is to use Q-tips to get wood glue inside the crack, then take off the back legs so the backbox is leaning backwards to close the crack, and leaving it that way until it sets and dries. Does that sound like a reasonable plan?
