Even though the cabinet was structurally sound, the lower coin door laminate had separated (if you know what I mean).  Tonnes of wood glue and clamps. How lucky am I this is the only wood separation.
Whilst the glue was drying, I moved onto the legs. The fronts weren't too bad. A quick coat of rust remover, WD40, buffer and Silvo, they came up nice for 30+ years. The back ones had no hope.
Luckily I discovered Neno on Aussiepinball. A brand new set 27" (27" or 28" legs, I know they were buggers to find). Why was I wasting my time removing rust?
Now got the cabinet down to bare wood, ready for primmer.
