It was only after removing everything from the cabinet that I realised how bad it was.
Check out the angle iron on the leg side of the cabinet picture.
The repair must have been carried out with the machine intact of playfield. Placing the straight edge along the body showed a huge bow out. Removed screws and re clamped the cabinet and glued. There was also damage to the bottom side where the base slots into. I made up a timber fillet and glued it into place. Planned off after glue dried.
Most of the corners were pretty good and sturdy. I was able to get away with injecting glue into any cracks/openings and clamp. A hypodermic syringe with a large gauge needle did the trick !
Bolt head taken back to bare metal. A wire brush in a drill chuck on the lathe made light work of it.
Cabinet filled and sanded.
Replaced the piece of timber where the glass plastic channel screws into.
