Like so many of these forty year old cabinets, this one is crumbly and swollen from water damage. In addition to all the damaged particle board, all the metal parts are lightly rusted, its almost like it was left out in the rain.
As much as I hated to do it, the lower half of this cabinet would need replaced. This would then require a re-stencil of the side art. Also the top panel, lower back panel, and back door would need replaced.
Below are a few pics of the progress so far. Also the metal plates used to mount the missing leg levelers needed soaked in Evaporust for several days. After they were cleaned up, they were bolted back in place, then four new leg levelers were installed.
These new pieces are held firm with wood glue and biscuits. Using the router helps keep the cuts perfectly strait, and will make blending in the new wood simple.
